Hi Q, Thanks for the info. It seems you frequently get conflicting details, particuarly if someone has something they want to sell you. BTW, an alternative to buying new drivers is to have them repaired. There are a few really good speaker repair shops that can replace surrounds, do re-cones, etc. It's probably less expensive if all you need are surrounds. Ping me off the board if you need a recommendation for this. Regards, Jim ------------------ Jim@analogbros.com

Al and Tom, Thanks for the replys. Al, you make a good point about waiting till the networks are installed; I _am_ trying to do this methodicaly, one item at at time. Yesterday I completed the squaker horn swap from the stock aluminium horn to the dampend plastic LaScalla horn in one speaker. After a few hours of listening I'm not sure of the results yet....seems it may be a bit over damped to the point of slowing transient response. Either dampening the aluminuim horns or undamped plastic horns may be a better option. I'm very impressed with the work both of you have done to integrate larger horns to Klipsch bottoms, but at this point I'm not up to the woodwork involved nor is a "naked" horn going to be acceptable. For now, I want to try and get the maximum performance using the stock horn with an improved (?) driver. Tom, I'm curious that you feel there isn't a better woofer than the stock Eminence that I'm using, though I don't feel that frequency range is much of a problem source for my system. The increased top end response of the T-350 _was_ what interested me along with it's efficiancy. I imagine the sensible thing to do is to wait for the xover networks to arrive then replot the response and listen carefully. Thanks again! Regards, Jim ------------------ Jim@analogbros.com

Hello Al, Thanks for the reply. Here is my reasoning for looking into a more efficiant h/f driver. I made some response plots of my system and found the largest discrepency to be in the 10K and up region where the response is dramaticaly down. Taking into account your x-over design which allows for various squaker taps, it seemed a more efficiant h/f driver _could_ be integrated well into the system and perhaps alleviate this issue. As for the woofers, I had initially been searching for a pair of JBL D-130As; after a few conversations with some driver suppliers, I was advised that that would be an incorrect unit to use in this application. The Eminence Kappa was recomended as being quite similar to the OEM part, but about 3dB more efficient and much sturdier. I forgot to mention that I'm also using a sub (Velodyne UDL-18) crossed over at about 72Hz. By virture of the bi-amp system at the wooofer/mid interface (using a combination of low level passive and active x-over elements), I felt it would be possible to make any required balance adjustments via the power amp levels to compensate for woofer level. As for the squaker horn itself, seems many have suggested accoustic damping. I happened to have a pair of LaScallas' which the previous owner had done a pretty good job of damping the horns. I'm in the process of swaping out one to see how this effects things. Any suggestions would be most welcome as purchasing different drivers for expermintation can be an expensive proposition. BTW, a very impressive job you did on your Belles! Regards, Jim ------------------ Jim@analogbros.com

Greetings, I'm in the process of doing upgrades on my 1986 K (corner) Horns and have been reading this bb for a few months to get some ideas. I've been looking into different drivers and will probably go with the Emminence Kapas for the woofer. Not sure about the squaker driver (though I am installing dampened (plastic) horns from my LaScallas today to replace the aluminium stock ones. My current question is has anyone tried using the EV T350 tweeter (either in place of the stock driver or on top of the cabinet mounted seperatly)? I recall having read about it's use somewhere else, but couldn't find the article. Some info on my system: Al's x-overs on order, bi-amped with 75 wpc tube amp on woofer, 14 w mono blocks on sq/tw.
