Thank you very much for the info and links! I checked it out and used it, I've used several online calculations and WinISD-Pro and everything seems right on from what it gives me but I'm thinking the woofer moved up is throwing off it's expected calculations, probably the very reason Klipsch had to shorten the shelf for the Cornwall III, to let the woofer breathe more. I'm still stumped! I'm going to talk some more with the speaker builder tomorrow and see what we can come up with. Thanks!!

Hi, I'm hoping to get more expert advise here with my problem, posted in the 2-channel but this is probably more the correct area to post this in. I had a set of Cornwall speakers built, they used two 4inch Diam. ports with 4 1/2 length. These ports aren't working out, as they said they usually do but because I had him move the woofer up 9 inches from bottom motor board, like Klipsch did with the cornwall III, that he thinks I need to add another port most likely. So over the weekend, I took the 7 inch shelf (really 6 1/4) out of my cornscalas and put in a 10 inch self (really 9 1/2) to see what it sounded like, the reason for doing this is because my cornscala has the woofer moved up 9 inches from bottom motor board too. What I discovered is this: Klipsch had to change the port shelf for the Cornwall III after moving the woofer up because the bass chamber builds up pressure faster than it can be released. The 9 1/2 shelf sounds just like how it makes the cornwall's with the 4inch port sound, not enough air released for the ports. In Moulin Rouge when the wind mill blade passes through the view of a window.... it cannot be heard in the 9 1/2 shelf but with the 7 inch shelf it's back and can be heard, same thing with the cornwall with two 4"diam. ports, it can't be heard. It's like the woofer is getting too much pressure build up and being choked down, I guess. I'm not sure how to covert the 7 inch port shelf into what it would come out to using for 4" diam. ports and was hoping someone could give some insight here. Do I need to add one more port, or two? If I plug one port, the problem is worse... if I plug both, there isn't any bass. If I remove both ports out of the holes, things get a little better. Any help would be appreciated if someone can help me out here! Thanks, Sky

Hello to everyone, I'm hoping to get more expert advise here with my problem. I needed some speakers for my home theater room so I purchased a used pair of cornwall III. I discovered I liked the phenolic sound better so I sold the cornwall III and I had a speaker store build them for me, cornwall speakers. He used two 4inch diam. ports by 4 1/2" length. These ports aren't working out, as he said they usually do but because I had him move the woofer up 9 inches from bottom motor board, like Klipsch did with the cornwall III, that he thinks I need to add another port most likely.

Emotiva is very good! They are not cheap! They are built very well and compare well to the likes of Rotel, Parasound, etc. They have a better value price wise because you are buying direct from the manufacturer and by-passing the store/middle man, where cost are added to the product for each to make profit off of it, like retail is! I own some Emotiva products and they compare very well to much higher priced gear I have. They are well worth it and a great value when buying direct from the manufactuer.

LOL[<)]

Southern, the XPA-1 are nice. I've been impressed with Emotiva products so far, I also have the RSP-2 preamp and ERC-1 CD. The bass is amazing how deep, tight, and clean they sound with the RF-7 and XPA-1. I have Klipschorn's and Super Cornwalls and the RF-7 are still a favorite of mine. They just do sound a little differently. The RF-7 have alot of presence and I like that about them. TheFactor, sometimes I wonder if some people take the more presence and revealing as bright? I don't find them bright, just more revealing with the presence. I do remember when the RF-83 came out, I went to the dealer for a demo, the first time I heard them they sounded not very good and bright. A week later I talked to the owner and he told me come in and listen to them again that the salesman should have never put them on the receiver he had them hooked up to. The second demo was a big different from the first. It sounded pleasant and nice sounding 2nd time. Teaming the right gear to the speakers is a big step in getting things right.

RF-7 came first, then the RF-7 classic, and now the RF-7II. Crossover 2200Hz on all RF-7 Crossover 1200Hz on RF-7II

Mallette, actually the Rotel is smoother sounding with it's rounding out the highs, the Panasonic isn't as much and a little harder on my ears but not by too much. Flat vs more air in each note, again you won't understand until you compare the two, then you'll hear the difference, sounds flat on the Panasonic and more air and heft to each note on Rotel. I've easily listened to the Panasonic's trying to figure out the differences and harder to do until I compared them side by side, and all things become very easy to hear what the big differences are. I don't find any problems with high quality SS amps as you say you do, and not a tube guy, I've already tried that a couple of years ago. My liking is more very high quality SS amps. Your misunderstanding me, the Panasonic can fill a room but in a lighter way. You won't really understand what I'm saying unless you try it yourself. I've used the Panasonic on my Klipschorn's and it's easy to hear what I'm talking about. My intentions were just to post my findings, not to upset or insult anyone's usage, it's just my findings and my honest opinion. You can read on the Rotel forums how many feel that the RB-1090 is still better than the RB-1092 being Class A/B vs Class D and still feel the RB-1090 still is more fuller, more 3D, and airy sounding, if you read those maybe you can understand what I'm trying to say here, reading those may help explain it for those who have expressed this better than I can or attempt to. It's also very possible that you much more prefer your Panasonic sound, if so, that's fantastic, hang on to it because Panasonic no longer makes these anymore, they've decided to not compete with the HT amps anymore. I never said the Panasonic didn't sound good, I still have a couple of them around but I hardly listen to them because I do have better sounding amps that I like better. I still think the Panasonic is a great little amp for what it can do, it's features, and size. When you have the chance to try many different things, you quickly learn and hear the differences and that's the best way to get an idea what the differences actually are.

There are many who feel that Bryston amps sound too clinical on Klipsch speakers, I tried going this route about 3 years ago and felt it sounded cold sounding for my Klipsch speakers. Bryston works better for warmer sounding speakers.

I've played around with some of the class T and class D amps. They sound good and can reveal some of the detail and nice highs that some of the better amps can do, but they sound flat compared to the high quality ClassA/B amps. I've played around with the Sonic T, Onkyo A9555, and Panasonic XR-SA models, no question you are getting all the detail but the sound is like someone popped the air out of the music and less powerful sounding. Simple test of just taking a Rotel RB-1080 and a Panasonic XR-SA model and play them, switching between them with the same source playing and you can hear the difference. The Rotel can fill a larger room much easier, sounds full and rounded, like air is in it like a balloon, while the Panasonic sounds flat, less rounded sounding and less powerful sounding. The Onkyo A9555 sounds more powerful than the Panasonic's but still flat sounding instead of the full rounded airy sound of the Rotel. Comparing quickly sums up the brain what you are hearing and what each can and can't do. I like the more rounded sound of the Class A/B amps. The class T and class D are amazing for what they can do for their size though.

That's how it is with this hobby, you have to find what best fits your own likes. I don't care for too clinical, dry, or flat that takes out the more involvement and emotion to the sound but I don't care for ones that mask over too much in detail for a more pleasant sound. I like it more to the neutral side of it, yet detailed, dynamic, and involving, yet have the emotion in the music. I guess for some, you have to find it some where in the middle to your liking, there's so many choices out there to get you where you want to be. A friend of mine has a very laid back and polite sounding amp and speakers, it lacks the detail I like to hear, the mid-range is overly bloomy and very large sounding, it sounds nice but not all that accurate but he loves it. It's not as much to my liking but neither is my setup and speakers to him. He likes the detail and resolution he hears from my setup but he prefers he's sound like butter he said, slow, smooth, enhanced mid-range, sound at the speakers and not in front, and not very dynamic to the ears. All we can do is list out the differences between equipment to help one pick closes to his/her likes, or sometimes it just takes experimenting with different gear to figure out what sound you like best for your own ears. Kind of the reason I don't like to give my opinions on advice to someone with sound, I would hate to misapply advice to someone that has different taste than my own and have them unhappy with the sound they are getting.

I would still go with the Emotiva XPA-2, more powerful, doesn't have the added warmth like the Parasound, cleaner, clearer, same wide vocals as the Parasound. The Emotiva XPA-2 is built like a tank and has better binding post on the back.

Both are basically the same 15" woofer. They just do bass differently by design. Klipschorn encased woofer ports from the sides out into the room, while the CornScala ports direct, both woofer and ports, still a very large bass sound but much stronger centered by design. My Klipschorn's are very good in it's corners, I have no issues with it, it's the best they've sounded in this house than the other house, they are also the tighest fit you can get, it won't get any better than what I'm getting, that's not an issue, they are just doing bass differently.

Yes, if I had to pick between the two, I would pick Emotiva. I like a more detailed and cleaner sound and that's what the Emotiva has over the Rotel, for my likes. Both are very good, dynamic and powerful. The Rotel is a little more warmer sounding and a little more veiled and the reason it sounds a little smoother. I like the cleaner sound of the Emotiva without the added warmth because it makes the male and female vocals sound more accurate to my ears without adding anything to it.

Rivernuggets, I totally agree with you! Thank you!! Southern, I have a very large collection of solid state amps and listen to different amps in my collection, each has it's own sonic signature. I decided to try out a few value amps, so as of lately I've been running the Emotiva XPA-1 amps 500w per chan. I've been pleasantly surprised at it's value and performance, especially compared to how much the other amps I have cost! It sounds very nice with Klipsch speakers I have. I would love to have a pair of RF-7II in my room to directly compare it to my RF-7. The dealer wasn't running the demo on as nice of equipment, but it still sounded good, but would be great to hear what a pair sound like in my room on my equipment!! I purchased my RF-7 from the same dealer, he gave me a discount on them. I've been doing business with him for years. He offered me a decent discount on the RF-7II.

Same here, tried several tube varieties but realized that tubes aren't my cup of tea either. I no longer use tubes at all. I have a large collection of solid state amps, I'm always changing and listening to different amps at different times. Each has it's own sonic signature. I do have Emotiva XPA-1 and Rotel RB-1080 and RB-1090 amps, they are a very good value compared to some of the other amps I have. The Emotiva is a better value than the Rotel but both go well with Klipsch if all other equipment are equal in quality. The Emotiva has a clear, clean sound with wider midrange and on the neutral side. The Rotel is neutral but a little warmer sounding with midrange more narrow, more towards the center and ever so slightly less detailed that gives it a little more smoother sound. Both sound very good.

RF-7 are not harsh, I listen to my RF-7 for hours at a time and my ears do not hurt. It has to be your gear, something in the chain of the equipment, if all your gear is up to par, it rewards you with a very revealing, detailed, and stunning sound. It need quality every step of the way. My RF-7 are stock form just how Klipsch made them and they still amaze me on the presentation of presence and sound. The RF-7 are very revealing speakers so it needs all things equal on quality. In general, all Klipsch speakers I've had, has to meet these rules.

Wow, the cherry color looks great!! The RF-7II demo I heard was black, wish I would seen the cherry in person, it's beautiful!

Wow, nice pictures of the RF-7II and your setup. Looks like the RF-7II survived shipping well, boxes look like they came in great condition. I had the same experience with my RF-7, they sounded much better at home than at the dealer store, so I had a feeling you were going to like the sound even better at home!! The RF-7 have a more critical sweet spot but I noticed on the RF-7II that you can move more right or left at listening position and not lose the sweet spot the way the RF-7II has a wider dispersion of the sound. Your cat looks identical to mine, anytime I listen to music, my cat jumps up on my lap and listens with me. Enjoy the RF-7II for many years to come! I've had many speakers over the years but after I discovered Klipsch, I still only have Klipsch speakers because of their resolution, clarity, detail, and quality of sound they provide.

The listen demo I had with the RF7-II, they never sounded compressed sounding when volume was turned up on the gear I heard them on, they stayed crisp, clear, clean, dynamic, airy and spacious sounding, all while staying detailed and revealing. They sounded wonderful! Maybe they need a little more run time.

Thank You!! And congradulations on your new RF-7II speakers! I know you're going to enjoy them! They do sound outstanding! It's going to be a very exciting day for you in the morning! Report back after you get them setup and spend some time with them and let us know how they are sounding in your room, enjoy spending time with your new speakers! []

RF-7II vs RF-7 review: Ok, I called my Klipsch dealer today to see if they've gotten the RF-7II in for demo, I was really surprised when he told me they've had them in for a full week now listening to them. He said I should come in and listen to them that they sounded better than the RF-83, I told him I was more interested in how they sounded compared to the RF-7, he said you better come in and have a listen to them. I have RF-7 and was very curious about how the RF-7II would compare to it. Here's the changes I could hear: The RF-7II has a wider vocal presentation. The RF-7 has a more centered vocals in the middle. The bass sounded very good. Overall I was very impressed with the sound. I think Klipsch really did a nice job on how they sound. They aren't as in your face as the RF-7, the wider spreading of the top horn (probably from crossover design) gives it a little more smoother presentation since it's not as direct to your ears. I really like how the RF-7 sound. The dealer was telling me that they are really happy to see Klipsch bring back the RF-7 because it was always a better seller for them than the RF-83 were. He said Klipsch realized this and that is why they wanted to bring them back, and to improve the sound while doing so. I'm not sure about improved sound, they both sound very good, that would more depend on how one likes their sound, more direct to them or more spread out sounding before it reaches your ears. The only way I can try to explain this, is that the way it spreads the sound out is simular how the Klipsch heritage does. Also the ever so slight softened midrange carried in the cones of the RF-7 seems not as noticeable with the lower crossover point of the RF-7II but the RF-II has a little less fullness in this cone area since the cone no longer carries this upper crossover point. The RF-7II metal feet are a nice change from the RF-7 plastic feet, even if they look a little odd. The platic feet crack easy, I did so bearly moving mine when towing them in, so anything metal is better than those plastic feet. I was disappointed that Klipsch took away the binding post like the RF-83 had and kept to the RF-7 binding post!! For the price being asked for these speakers, I think it should have the binding post like the RF-83. Also the grills are now back to the peg type again! I have broken one of mine even carefully taking them off, a simple uneven removal will snap off the peg, I was very unhappy with the peg type and I'm very careful taking them off. It should have the magnetic holding grills like the RF-83 for this price in my opinion! I do like the new grill design with showing off some of the speaker in front! Are the pegs stronger than before? I don't know, I couldn't ask the dealer to let me test it to see if it would break off and damage his grill! The RF-7II sounded really nice, I was impressed! I like them very much. I still very much like my RF-7. At $1,000.00 more than the RF-7 it's really up there in price. I'm still very happy with my RF-7. For those that think the RF-7 sound harsh, will probably like the RF-7II wider top horn sound and less in your face sound. The whole time I sat listening to the RF-7II, I kept thinking how really good they sounded. I have nothing bad to say about the sound, I wouldn't mind having a pair! The RF-7II is taller than the RF-7 and I picked up the RF-7II and noticed it doesn't weigh as much as my RF-7 so I'm a bit confused how it's taller but weight is less? How is the RF-7II internal volume larger with same size 10 inch cones and still the bass seems very good. The RF-7II has a very nice sound, I can't see how anyone wouldn't really like them!! Which do I like better, the RF-7 or RF7-II? It's hard to answer, I like them both. They are just a little different in how it does the sound. It doesn't make me want to sell my RF-7 but does make me want a pair of RF-7II! My friend who went with me to hear the RF-7II has listened to my RF-7 many times, his take was this: RF-7II sounded really sweet, he likes how it has a wider sound while keeping to the imaging and detail of the RF-7 but taking off the edge that the RF-7 can have sometimes to his ears. That was his quick take on it when I asked him what he thought. I think Klipsch has another winner on their hands!!

Just found out today from my dealer that they actually did finally get the RF-7II in and I went in and listen to them so now I have a very good idea how they compare to the RF-7. They do sound wonderful, I'll post my review in the 2 channel section since I only listened to them in 2 channel. Enjoy your new RF-7II, I know you will! []

I'm more curious on how the RF-7II compares to the RF-7. It will be a tough act to follow to out-perform the RF-7 so I've been waiting for the dealer to get his demo pair in for a listen but so far they still do not have a demo pair setup.

I have newer AK4 Klipschorn's. I used to have them in a very large room in a different home I used to live in. I struggled to get bass output as well as my CornScalas (Super Cornwall), it had great corners. I sealed the Klipschorn's in the corners with lining it with pipe foam as many have suggested, that did help the bass some but it was still just ok. I've always heard Klipschorn's to be used only in large rooms and read many warnings not to use in smaller rooms. I moved into a new home, I did not have perfect corners in the large rooms, only in one room that starts at 12ft long but then tappers down to 10ft at the listening chair, sort of like a triangler shape room, it's an odd shape room. Ceiling is 9.9ft tall. I thought this room would NEVER work but I had no choice but to use it in that room if I wanted to keep the Klipschorn's. What a shock! I've had the Klipschorn's in 3 different rooms over time in differnt homes that were larger rooms but this smaller room really shocked me how well it sounds! Now the bass is about the same output of my CornScala but the complete room turn's into a wonderful cloud of music, it's the best I've ever heard the Klipschorn's ever sound. I was shocked, I thought it would be the opposite. It just went to show me that I pre-judged something that wouldn't work, but it worked and did so far better. This might have something to do with the odd shaped room but it works! The vocals are smooth and enjoyable, I hear more detail than before and it doesn't over-power the room, even listening to albums at the same volume I listened to at the other house. Very strange! Sometimes you have to just try it and see how it works. If I use the Klipschorn in any of the other rooms, I would have to close the backs on them, I've thought about it but since all of the family really likes how it sounds where it is now, I've left them in the corners of that small room.
