I've spent more time on the Klipschorns. I've always had good bass with them, someone did suggest to use pipe insulation around the back to get a tight seal around them. I picked some up at Home Depot and it seems the bass is a little better, or maybe all in my head, but it sounds like little more, little tighter, little fuller. I have some good gear that mates well with Klipsch, learned years back when I started out with Klipsch speakers it needs good gear . I did take a Solid State amp I have that has 360watts per channel and more warm sounding to check the brightness out. Giving more current helped get some detail and resolution out more but sounds little bright from my other Klipsch speakers, maybe it's the room, it has mostly carpet. Another person told me it's the AK-4 crossovers too! Brighter sounding out of the past Klipschorn crossovers. I've never heard past Klipschorns to compare to know for sure. When I say 2D, not meaning to imply the Klipschorns are only two-dimensional in sound but when compaing it to the Super "C" speakers, it's the only way I could think of how to explain the difference I was hearing, probably not the accurate way to discribe it and wondering if the difference was from the tractrix horn or crossovers. From what I'm hearing, sounds like the tractrix horn is making the difference with the fill-in soundstage and detail, resolution, bright would be the crossovers? It's hard for me to imagine that Klipsch would design a crossover (AK-4) to sound more towards the bright side, so I'm thiking it must be my room? I guess the next thing to do is add more damping materials to the room and see if that helps. I like the way the Klipschorns sound, just want to get them where I can hear the detail and resolution without having to turn them up at a higher volume to hear it without being too loud, gets brighter at that volume for sure. I guess it could come down to trying new crossovers to see if this helps, just want to make sure it's the right choice so I don't change them and find they are still doing the same thing? Thanks for all this great information so far!! Very helpful!

Thanks HarryO, appreciate that! True, you're right, it is a very good feeling! I saw your Wallrus you built some time back, very nice!! Love the color stain you picked too, Great job!! Bet they sound great!

[] Thank you [<)] []

From some reviews I've read on that mid horn, it gets some great remarks of being very good. I don't have enough experience to know personally myself though how different it would be from others. I have several system setups and I was listening to the Klipschorns some more tonight with different amps. What I did notice tonight is that I have to give the Klipschorns more volume and then they start to open up and start sounding more detailed and dynamic but it's at louder volume than I listen too so it's loud, even at 20feet listening position where I worry if I will disturb the neighbors. I'll have to spend some more time with them to see if I can figure this out?

I don't have soldering skills but when I built my speakers, I needed to solder the wires to the drivers, binding post, and crossovers. I searched Google for: solder "how to" I found some tutors but some bad ones where I still didn't get it, then a came across a video on YouTube that one guy has on there that was an excellent tutor on how to solder and explained it really well. I was able to teach myself from that excellent video he did. I did a few test soldering until I got it down and them did the soldering on the speakers. So it's possible to teach yourself like I did by watching that video on how to solder. Good Luck!!!

The Super "C" Walls are using basically the same drivers as the Klipschorns.

I have a set of Klipschorns built in 2004. My plans were to keep it all stock and never modify them but after building the Super "C" Walls See here: http://forums.klipsch.com/forums/t/102542.aspx speakers, I'm thinking about what I can do to them to get the level of performance that I am hearing in the Super "C" Walls. The Klipschorns sound great but I'm hearing a little more detail, resolution, more dynamics (larger?), taller sound, fuller vocals, and more natural sounding. I would guess the taller sound is because of the taller mid horn? The Klipschorns also seem a bit brighter sounding and more 2D sounding compared to the Super "C" Walls sounding not as bright and more 3D sounding. I don't even know how to describe it but the only way I can think of how to. If I change out the crossovers in the Klipschorns, will this give me more of the 3d sound, or does this have to do with using a tractrix horn in Super "C" Walls? Will I have to change the horn on the Klipschorns? (I'm hoping not). The Super "C" Walls are using Bob Crites CornScala crossovers and if I remember right said sonicap on it. If I changed to Crites Klipschon Sonicap crossovers, will this give me the more 3d detail I'm seeking? I'm looking to bring the Klipschorns to the next level and wanted to ask your help if just changing the crossovers will do it? Thanks, Catbo

The Super "C" Walls are sounding very very good, incredible sounding to my ears. I was listening to these last night with a friend and he asked me when was I going to build his Super "C" Walls and when was I going to sale my Klipschorns. I told him he can't talk me into it, he will have to build it himself and I'm not going to sell my Klipschorns. He said I will not want to listen to them anymore with how the Super "C" Walls sound. Ok, I must admit that I am really liking the way these Super "C" Walls sound. I never was going to modify my 2004 Klipschorns but now I'm thinking I might. I would like to get the performance level out of them like what I'm hearing in the Super "C" Walls. I am wondering if all I need is a change of crossovers will do it? I guess I should ask for help in another post for my Klipschorns.

I forgot to mention for the bass ports, I also added inlayed veneered birch around the bass ports to give it a more finished look so it wouldn't have that utility look that my other half calls it without the veneer.

[] Thanks [] I wondered about this myself but if there is an advantage to having the tweeter in the middle (below the midrange) vs on top, the difference was very subtle to my ears, but a couple of friends that helped me out on where to place the drivers, both have much quicker ears than I on changes in sound so I trusted their ears more than mine because it takes me longer to hear changes in sound of what I'm actually hearing, I have to study if for awhile to figure it out. I did some test runs on positions and both liked it in this configuration best, said it was the most balanced sounding. I also sketched out different speaker layouts because my original plan was to put the tweeter on top above the midrange, it would have worked but after showing the sketches to many people and asking which looked better, most picked the look with the tweeter in the middle, saying it looked better that way because the mid horn so close to the woofer. The cutoff chamber doesn't leave much room between it for the mid horn and woofer, because the woofer was positioned higher up like the Cornwall III but it could work, just tight. It turns out the two friends who said it sounds better with the tweeter in the middle below the mid, also came up with a look most people liked so I went with that because I liked it better than the other looks/sketches I had. My two friends make sure I give them full credit for it too! [] and I do

Thanks again for all these compliments!! The crossovers are Bob Crites CornScala crossovers crossed at 400 and again at 4500. You have good eyes! Yes, it's more than two speakers, it's four. I have one pair in the room with the Klipshorn's and the other pair in the room with RF-7's you see in the pictures I posted. Here's a picture with all four together.

Thank you for all the kind comments! It's a great compliment coming from the Klipsch forum! I do have some pictures I took during building, not many as I should have but have a few I can post. I forgot to list the drivers, sorry. The internal volume for the bass is the same as the Cornwall cabinet, I just used a cutoff chamber, I'll post a picture of it. Drivers: Midrange - Atlas PD-5VH (Phenolic) Tweeter - Eminence APT-200 Super Tweeter (Phenolic) w/90x90 horn Woofer - Crites/B&K Sound - Eminence CW1526C (cast frame) Crossovers - Crites/B&K Sound - CornScala Crossover 400/4500 Midrange Horn: Goldwood GM-450PB 17.7 inc X 9.8 inc. (90X40) http://www.audiolabga.com/mal_cart/data_html/GM-450PB.html The sound is large and airy simular to the Klipschorns, little more relaxed, little less in-your-face but still very detailted, dynamic, smooth, and a well rounded sound. Both a little different in sound but it still has very much the Klipsch signature sound. I don't want to take anything away from the Klipschorn's because I still like it very much. I find it very relaxing and smooth just listening to the music flow out of the Super "C" Walls that is very pleasing and the subtle detail I'm hearing. Very impressed with the low bass too! I thought I might like the titanium mid and tweeter but I think I really prefer the phenolic sound, very clean and clear and very nice quality about it.

I wanted a pair of Cornwall's over the last 3 years, I've had no luck finding a used pair locally in great condition. Tried to buy new Cornwall's but after failed attemps with 3 Klipsch dealers telling me it's "special order" and will do no price dealings I realized I wouldn't be owning a pair, several people mentioned the new Cornwall has a smaller horn from the original that I should look into building a pair of CornScala's. I research the CornScala with great interest, admiration, and amazement! It had me wishing I could have the know-how to build like so many others have. After much research and learning from others, I decided I had to try to build my own if I was going to really own a pair of speakers like I really wanted. So this is my attempt at building a speaker type I really wanted. I have no woodworking skills, I have no shop or garage with work tools. I had to build these with my own two hands with few hand tools I bought to build these. It took me over 1 month to build the speakers because I could only work on the speakers in my free time only. Long work hours didn't offer much free time but It's finally completed. I've started working on front grill covers, it should be completed soon. Each speaker was glued with very strong bonding glue and each speaker has over 200 screws (internally only) permanently holding speakers together. The screws were needed as I had no way of holding the speakers together while the glue cured bond. The speakers were sealed completely at all joints/seams and also followed with complete silicon seal inside to ensure for air tight enclosure. Speakers were also braced and damping materials used inside. Front, Top, Back, Bottom, and sides of speakers show no screws as screws were done internally only so it would appear to be screw-less. I'm extremely pleased with the results of the sound quality from the speakers. It has exceeded my expectations and more surprising it produces the type of huge quality bass that is unbelievable in terms of clean, clear, crisps, solid, quick, very tight, with resolution that resonates througout without any hint of sloppiness/muddy bass, yet extremely accurate and fast. Speaker as a whole has a very uniform well balanced sound, smooth, detailed, dynamic, very realistic, very involving. Everyone who have heard the Super "C" Walls say they sound wonderful and think they can talk me into making them a pair but I've told everyone they will have to make their own! I wanted to call these "Super Cornwalls" but a few suggested that I call these [super "C" Walls] because Klipsch owns the Cornwall name so that is how I came up with the name Super "C" Walls for these speakers. All parts and high-grade birth wood purchased at retail prices, total cost about $1200.00 for the pair. Thanks to all who shared their projects and encouraged me to not be afraid to take this project on! I'm very satisfied with the outcome of these speakers! I'm set! Thank you!

I have RF-7 speakers and have a collection of different amps and Klipsch speakers. I find myself listening to the RF-7 much of the time with the Rotel RB-1080 (200wpc) and Rotel RB-1090 (380wpc). It's a great combo, I've been very pleased with the results. I also like the Rotel RX-1052 and Rotel rates their power very conservatively, and yes the RX-1052 will give the RF-7's the quality watts/power it needs. The Klipsch and Rotel forums have many satisfied users of the Klipsch/Rotel combo, do a search and read up on some of the comments. I don't think you can go wrong with this combo, it really brings life into the RF-7's, I was very impressed!

Thank you all for all your help, I really appreciate it!

The speakers had high voltage damage from the owners son and haven't been fixed in 17 years just sitting at office storage room and said they were mine for only $100.00 for the pair. The crossovers didn't work but now have crossovers working, only 1 midrange not working in one speaker and the other the tweeter doesn't work. I have other Klipsch phenolic and titanium speakers, the titanium just sounds clean, clear, smoother and little more detail to me vs the phenolic for both the midrange and tweeter so I was just hoping to come up with changing them to titanium drivers that could possibly be compatible with these Cornwall's since I have to fix them. The Grand-HF-T and KPT-904-HF sounds very nice, would love to try that but I'm too limited in the know-how to know where to start with that. speakerfritz, what are the other options I could try? If too large, I could always make it work from building a top section for it. Thank you every one for the advice so far, much appreciated !!!
