Was used to hearing them on Odyssey Stratos Mono Extreme Amps with the Odyssey Tempest Preamp. I'll have to put the Emotiva XPA-1 monos with Emotiva RSP-2 pre and see how that is noticed next! Calling the Panasonic ear stabbers really gets me! It doesn't sound that way to me! I do like very detailed sound that isn't softened though, I know some like the sound softened a bit but I rather hear more detail at the cost of not being softer. []

I was using my Panasonic SA-XR on my Klipschorn's last night and my other half sat down and after about 10 minutes, asked why are you listening to that? It sounds like ear stabbers compared to the other amp. [:|] I said, wow...I wouldn't go that far! Other half said, you can't tell me that your ears aren't hurting by now! [:^)]

Gary Anderson, Try and get some pictures while you are building so you can share with us! Curious to see what your build looks like now!!

Wow Cronwall70, You are making much faster progress than I did! It's looking great. Yea, your area is getting a lot of rain! Need some sun and dry air to cure and dry that glue up from the damp air your getting! You are going to be happy and proud of your new build! Looking forward to seeing the final results!

Mike Dubay, Nice bookshelf. Nice woodworking skills!

Ok, made the deal, will pick up the diaphragms on Saturday. Good news is, he said a co-worker gave word that he will buy the Chorus on Friday and pick them up, so it should be gone the day I'm there so no chance of me coming home with them! [Y]

I think he will get it figured out. Shouldn't take too much effort to figure it out, once he does, I think he will be pleased with the RF-7 bass performance, and overall sound

No, that doesn't sound strange at all. I haven't tried the oil cap cans, but from what I gather from what others say between the two, I have a strong feeling that I'll prefer the caps I'm using now over the oil cap cans. Some say the oil cap cans soften the sound out a bit. I don't really like mine to be soften out, I like it crisp, clean, and detailed, down to the last drop. So it will depend on what sound-wise you prefer. Atleast I won't have to worry about them leaking as they age as I've read some complain about. Might depend on what sound you get used to first, some don't like the change, but then some do. I've been happy with the Sonicaps. If you like your sound soften out a bit, guess the oil cap cans are the way to go, but aren't they hard to get new, or is another company making them now that GE isn't?

Strange as it is, got an email from someone that lives not far from me, about an hour and half drive that has an extra set of titanium dia. tweeters and titanium dia. midrange and said they have never been used, had bought an extra set when he changed to titanium on his Chorus 2 years ago that he purchased from Klipsch. Said he was going to sell his Chorus because he's upgraded to some huge speakers that I have never heard of, has my curiosity up. I think I might buy the diaphragms from him, he has a reasonable price, if anything to change the polymer tweeters to the titanium. I could give the mids a try. I'll probably go get them but I won't be able to really try things out until I get my HT build speakers completed. I'll just have to make sure I don't come home with the Chorus speakers too! Too many speakers already and the other half will have my hide if I attempt to!

Agreed, I've only used high powered/high current/and very high quality gear on my RF-7 with excellent results, but I don't know what an RF-7 sounds like on anything other than what I use. Probably why I disagree with the others that say the RF-7 are too top hot!

I'm very surprised no one has answered this by now. Yes, because the K-77 can't go down to 4500hz without an extreme slope crossover so you will blow the tweeter. If you use A-4500 crossover, you will have to change to a tweeter that can handle it. Bob can talk you through things and help you figure out which direction is the best way to go for you. You can peek around his website here: http://www.critesspeakers.com You can contact him here on the forum or on his website via email on the "Contact Us" You can also do a search on the forum for A-4500 to read up on some of the users who tried this. Good luck!

OK, I stand corrected from a couple of email reminders, so I'll correct myself. The tweeter from Polymer to titanium was said to be an improvement. The tweeter from Phenolic to titanium was said to stay with the Phenolic, but I was told Bob has a newer titanium tweeter dia. that might compare better now, first time I heard this, I didn't know he has a newer version? Guess I'm the last to know these things! The midrange from Phenolic to titanium had mixed reviews, some even said it seemed to be missing an octave or two from males voices and certain notes. Hum, interesting! I hadn't heard the octave one before.

No, you aren't crazy. I learned this years ago. A high powered/high current high quality amp will always give more authoritative bass with better control, and better overall sound. I used to think otherwise until I started getting more heavy into audio and trying many different equipment and speakers. It was a learning experience you only get when trying various products.

> John Chi-town said: Can you believe that this discovery came about by me losing an original driver while trying to install BC's phenolics? I remember reading a few years back with some replacing the midrange and tweeters with the titanium versions on the Forte, Chorus, and KLF models. I remember thinking about trying it with my Klipsch KLF but there were mixed reviews on going from phenolic to titanium. Some loved the change and others liked the phenolic better. Some were saying the titanium gave a little more distortion/ring that some people take as more detail, where as the phenolic didn't have this problem because it was a resin type material vs metal, a natural damping that didn't cause the ringing. I didn't try it in my KLF-20 after reading some reviews on it from one of the other audio forums they were discussing it on. I have no experience to say either way because I didn't try this but remember it being done a few years back and thought about giving it a try. Ok, here it is, looks like it was (marems) that may have been the first trying the tweeter and midrange to titanium. http://community.klipsch.com/forums/p/55776/539527.aspx Not very long ago I purchased a used pair of Cornwall III but ended up liking the Klipsch phenolic mid and tweeter better that I'm used to on my Klipschorn's and Super Cornwalls, so I think I'm more a phenolic guy. The guy I purchased the Cornwall III from had extra 52ti and 53ti diaphragms that he gave me with the speakers, both are the same so I don't know why Klipsch gives them different model numbers, they look the same to me. I did talk with Klipsch tech a few years ago when I was reading about guys changing to the titanium mids when I was thinking about trying it on my KLF-20 and Klipsch strongly advised me not to do it, so I didn't. Not that it does or doesn't mean it's ok.

I'm a bit confused as to why you are having bass problems with the RF-7 as you describe. I had Martin Logan Summit back around 2005 or 2006 and I found the bass to be more open with the RF-7 for the room I had those two in, and a bit different bass from each other. I've always found the bass of the RF-7 to be tight, clean, fast, snappy, and never slow, boggy, or muddy. In-fact, I've been quite impressed how well the bass on the RF-7 do sound compared to the Cornwall and Klipschorn's bass I have. The RF-7 hold it's own quite well. Does your ML have built in amplifier? This is where you may need to experiment with, try a high powered/high current amp with the RF-7. I have several amps that range in different watts per channel. I've always used the RF-7 with 200watt, 400watt, and 500 watt amps and the sound and bass have always been very good. Your built in amp on your ML is probably giving the woofers more power than you are giving the RF-7?

I would say yes, it does require some break-in. I've built 3 builds so far with Crites woofers and Eminence woofers and family members had to remind me on one of my recent builds when I thought the bass was lacking, they said remember you went through this on your Cornscala but after a few hours the bass started getting much better. I had forgotten about that and was just reminded of this recently when I felt the bass was lacking but I let it run a couple of days and the bass was much better but it continued to get better over that whole month of usage. I would say yes, in my experience, the spider and surrounds need to loosen up from stiffness and the bass therefore gets better after this break-in takes effect from the builds I've done so far. I'm keeping this in mind as I'm in the process of a new HT build now, using Eminence Woofers (Eminence Kappa Pro 15LF-2) When I purchased my Klipschorn's new a few years ago, I remember it took the bass some break-in as well before I started hearing what bass it could really do. Because of my experience from this, I think sometimes some drivers might need some break-in.

Looking good! I made my Cornscala (Super Cornwall) from this forum (Catbo design) and made them out of birch. I was very pleased with the looks and sound quality! Good Luck and have fun! [][Y]

That's not the bass I'm getting from my RF-7, you need to experiment with speaker positions until you get the bass right for your room. I have my RF-7 probably about 2 feet from the wall and about 3 feet from the side walls, you'll need to experiment what works best for your room. Good luck.

Some of the Al K crossover pictures I've looked at when on his website, were using Sonicaps and Solen, looks like the kind (model) I'm using.

If I remember right, I thought I read some where that the oil caps were made by GE but they stopped making them. My Super Cornwall's have Bob's crossover that use the Sonicaps that are white in color, my AK-4 have many yellow capacitors from medium to large, and the Solen Metallized Polypropylene Capacitors I just purchased are black in color but all of them look the same on the outside but I don't know if they are the same on the inside!

Well, if you close the backs on the Klipschorn's it makes it much more workable in a room, than that is probably the way to go if you want a fuller and more airy sound. I use to own the B&W Nautilus 800 in Tiger Eye finish but was listening to my Klipshorn's more during that time and ended up selling the B&W. They were very heavy and a work of art but I still prefered the Sound of the Klipschorn's overall over it. Sometimes I regret selling the B&W because I really liked the looks of them and they sounded great but the room had both the Klipschorn's and B&W and my other half was on me enough to pick one and sell the other so the front room would have more space.

Yes, that's still a good deal! I paid $400.00 for mine new. I saw them sell as cheap as $300.00 later on and I would have bought a couple more just to put away for future use had I known Panasonic was going to stop making them, with all the speakers I have, I could have used them in other rooms in the house. Real shame Panasonic stopped making anymore SA-XR models, they felt the percentage sales for the HT market was too low for these and decided not to compete in HT market anymore. One would think as popular as these units got over the internet, that it would have been enough to keep putting out more models!

Congrats on the finding, enjoy! []

It's my understanding from every thing I've read, that it's all digital up until the point of sending to RCA, and then it's converted to analog that still keeps to a purity close to it's original form, and why it's difficult to hear a difference. Soundwise, I don't think it's enough to worry either way of which to use, it's all good.

Very interesting! I've never seen pictures comparing these differences. I just purchased Metallized Polypropylene Capacitors for my HT build. The speaker technician that has been working with me, and building my speaker boxes for me, recommended that the Metallized Polypropylene Capacitors were the way to go for the detailed sound quality I am looking for. Hope I won't be disappointed!
