I have changed Cornwall 1 xover from B to B2, I am glad that I did. B2 provides substantial, very noticeable sonic improvement over B.

I have a pair of cornwall 1 that is currently using the B xover, I would like to convert the xover to B2.
Per the difference between the B and B2 schematics, I only need to do the following:
- Woofer circuit - add a 20uF in parallel. No Change to Polarity +/-
- Mid circuit- replace the 4uF with 3uF. Change polarity to -/+
- Tweeter circuit - add a 245uH in parallel. Change polarity to -/+
My only issue is that I can't find a 245uH inductor in Canada, can a 14AWG 0.24mH (240uH) be used as a replacement?
Thanks,
Please, delete this topic; I have found the answer in this old topic.

Virtually the same, Inductors range in tolerance good ones are 1-3%.
Removing the steel screw from the inductor will effect the inductor more along the line of 10%, and may have an subtle audible difference.
Thanks for the answer; I just posted a new topic asking exactly that. I am converting my cornwall B network into a B2.

I have forte I, chorus II and cornwall I, all in the same 18x14ft room. After listening to each of them almost on a daily basis for about 3 months, I kept the chorus II in that room, and moved the other two to different rooms.
Performed the same test in a 11x15ft room with Heresy II included in the lineup, Heresy won hands down, and forte I was close second.
This is to say that a lot depends on the room size and layout.

Is anyone here using the Russian PIO capacitors in their Klipsch speaker crossovers?
I have been rolling caps in my chorus II and cornwalls II, so far all of the boutique caps that I have tried, leave me wanting for more.
I just replaced the 2uF tweeter caps with the Russian K75-10 hybrid-PIO caps in my chorus II x-overs, and I am quite surprised to how good they sound. I am so happy with their performance, that I just ordered more to replace the caps in my cornwalls.

My chorus IIs are currently being driven by a Yaqin MC-100C, and the combo sounds amazing. The Yaqin is a lot of amp on the cheap.

I currently own both -- cornwall II and forte II; while both are excellent and can't go wrong with either, but if you have to pick one only, I would go with the cornwall. Bigger soundstage, more open sound than the forte. Ex: with the cornwalls, you not only hear the bass, but you also feel it, with the forte you simply hear it.

You guys have convinced me. I am in Ottawa Canada, the speakers are in Toronto, I am heading to Toronto tomorrow to pick them up.
Thank you again for your advice.

Klipsch recommends a minimum ceiling height of 8-1/2 feet for Klipschorns. The Khorns will work in your room, but they won’t be able to sound their best. It may be because the squawkers and tweeters would be closer to the ceiling than Paul Klipsch would have liked, due to early reflections from the ceiling causing a less sharp image, in the same way that long ago, when we used rabbit-ear TV antennas, we’d sometimes get a faint “ghost image”, which would mess up the view.
However, if you get a great deal on a pair, and are happy to listen to them in a compromised situation, why not get them? Are you planning to live there for a decade or more, or do you have a roomier home, with higher ceilings, in mind for the not-so-distant future?
Only you can decide what’s most important to you, and which factors are less important. Good luck on your quest for great listening!
I do have bigger much bigger rooms with 9ft ceiling on the main floor, however, I never really spent anytime in these rooms; I spend most of my time in that basement working room, which is why I want them there.

Thank you guys,
I have the cornwalls as well. I just cleaned the room and tried the corns there; they sound fantastic.

Hi Guys,
I had the khorns before, but because of a few busy years I had no time to use them, sold them 3 years ago; I have been in constant regret since. I simply can not wait anymore I decide that I will buy another pair. But the problem is -- the only room I have available is my home basement office room, and it is only 15x11x8ft, not only that, it has a large desk with 3 large 27" monitors. Will that be acceptable if the khorns are placed along the 15ft wall and I sit way back at the 11ft wall? Ceiling height is just 8ft.
See attached a picture of the room
Thanks a lot.

I have the following pair of Klipsch horn for sale in excellent condition. Manufacturer date 1977.
I bough them in 2007 from a fellow klipshter (he bought them new in the early 80s). I have been using them once a week (2-3 hours on Saturdays) whenever I'm home
I have upgraded the tweeter and cross-over with Bob Crites A4500/CF125 kit.
I also updated the mid-range diaphragm with diaphragm from Bob Crites.
since I don't have a perfect corner, I have created two false corners as per klipsch instructions.(They are included if you want them)
The two wings are just for cosmetics, they have absolutely no effect on the sound. I have the original wings as well.
Asking $2000 for them. I'm in Ottawa (Kanata) Canada, of course no shipping, pickup only at my house.
See attached pics.
thanks,

I'm not going to replace them. I'm selling them because I have not used for months.
But I do have a second 7.1 system based on the RF-83 series

The speakers are in excellent condition. I upgraded both the tweeter and the cross-over with new parts (B&K Sound Type A/4500 Crossover/ Crites CT-125 Tweeter) from Bob Crites (http://www.critesspeakers.com/).
I created the wings to emulate the Jubilees look. (I still have the original wings).
Due to the size of these speakers I will not ship, pick up only at my house in Ottawa, Ontario (Canada).
$2500

The thing is I find the RF83 to be not too musical for 2 channel music.
Therefore, I disconnected the metal brackets that link the high and low speaker connectors and connect the heresy in parallel with the RF-83 low end
The RF-83 provides the low-end and the heresy provides mid and high.
This combination is breath taking.
However I'm wondering since there is no amp input to the tweeter wheter this can damage the tweeter over time?

Hi fellow Klipschters,
I have been looking for a tube amp to power my RF-83s
A fellow Canucks offered me a pair of Shanling SP-80 for $1200CAD (==$1190 USD) .
Any experience with these amps?
They are 50Watts/ch, is 50w/ch enough to power my RF-83s to75-85dB level?
Can I find better tube amp at that price range?
Best Regards,
-
I have found the root cause of the problem.The relay (part number NAIS LK1aF-24V, color black, right on top of the main power module) that turns the system on is no longer working.
If I short the COM and the ON pins of the relay, then the subpowered on fine.
I then went ahead and replaced the part with the equivalent, and voila!.

I have the exact same problem with one of my two ultra sets.
I noticed the problem yesterday when I went to turn the system on.
When I press on the Pod power button, nothing happen. I opened the back panel of the sub from both set of Ultra subs, swapped the fuse between the set that is ok and the one that's not, and the fuse is not the problem.
I then swapped one of the 3 supply modules, and it is not the problem. I believe the problem may be due to the main supply block.
The sub is not hot, no burned part, no noticeable problem with any of the components.
But, I will keep swapping module between the two systems until I find the exact module that 's causing the problem, and from there I can locate the exact component causing the problem.
I'll keep you updated on my findings.

Guys/Gals Help me decide.
Here it is, I have a fellow canuck offered to sell me a Shanling CD T300 ($7000 US) tube CD player for $2500 US.
I have read multiple good reviews about this CDP. But the problem is I have never used a CD player as my 2-channel playback. I'm curently using an HTPC based on the Lynx 2B (http://www.lynxstudio.com/product_detail.asp?i=12) audio PCI card. The analog out of the Lynx card is routed to a BAT VK-31SE tube preamp . All audio files are encoded in the FLAC format, and the sound is absolute breath taking.
My Question are:
Should I buy this CD player? Anyone transitions from the HTPC route to an actual CDP?
Has anyone ever witnessed a competition between a really nice CDP set up and a high resolution Computer Audio set up?
Which set up would you rather have if it was going to be delivered to your house tomorrow? the Shanling or the mentioned HTPC (leave cost aside, I'mreferring to sonic performance)?
Can this CD player really outmatch my current HTPC setup? I just don't want to spend $2500 just to find out that it sounds the same as my current HTPC system
The reason I'm asking is I never put my system against a CD based system, I take the HTPC route due to its simplicity and ability to have access to thousands of audio files at my finger tip.
Here is the rest of my systtem
HTPC::Lynx 2B -> BAT VK-31SE (Balanced In/Out) -> Classe CA-400 ->Klipsch Horns
If I decide to buy the T300, it will replace the HTPC::Lynx 2B from the chain

I Had 2 pairs of RF-7, I replaced a pair with a pair of RF-83. I usally listen to 2-channel music.
Then a while back a pair of Heresy showed up on my Local used item market.
I bought them and compared them against both my RF-83 and my RF-7. Same setup, same room, I simply switched the cables between the speakers while playing a song I know very well. Since then I'm using the Heresy for music listening and RF-83/RF-7 for movies playback.
I was so impressed with the Heresy, I then boutgh a pair of KlipschHorns.
The RF series while good, but are not in the same league with the Heritage.

It would have been so nice if someone had put a list of the caps.
