yeah, well, it's topics to chat on. Not to mention what is being talked about here is BI-WIRING, not bi-amping.

Just re-found the KAC and re-aquainting myself. have a pair of original kp301's (black, corners, and black grille cloth) bought new. They have served well as mid-sized reinforcement speakers. Some years back, when moving them, one was dropped straight down about 2' on concrete and shifted the woofer magnet, locking the VC. . Someone online (here perhaps...?) mentioned that they had a pair of LaScala woofers and I could have them (yes... that's right.. shipped and all... I am forever indebted...). Got them, installed them and the system sounded awful... thin in the extreme. The original woofs were 4ohm, the LS woofs were 8. My answer, considering what I had available, was to bi-amp them. crossovers make re balancing woof/hi easy. Once balanced with the original x-over point they were better than original. They took a years-long rest and are now in a living room that they do surprisingly well in... about 18" off the floor, no mid-bass room hump and remarkable low-end extension. It took me weeks of minutely zoning-in both a preferred Xover point (ended up lower than spec around 900) and the LR/R Hi/Lo balances but I haven;t fiddled with them in months now and just listen. My only tweak would be to drop the mid horn by 3dB or so but that's still the original mid/hi xover so untouched. An EMOTIVA preamp, CARVIN 1204 amp (200W x 4).

Briefly... years ago I bought a pair of kp-301's (original EV-style squak/tweet) for a very good price, new, at a music store that didnt know what they were. Used them for years and then one of them slipped fell straight down while loading them, to the concrete and shifted the magnet on the woofer. later a wonderful benefactor offered a pair of LaScala woofers which I grabbed. They are apparently 8ohm drivers while the original 301 woofs were 4 ohm... so, a VERY thin sound. As an answer I chose to biamp since the crossovers are good with that. woofers on one channel of [power and the internal passive mid/hi on another. Marvelous. recently got them out of storage and have spent a few weeks tuning them up and balancing them. I had forgotten... ! The room they are in is not large but sounds very good and the lo end extends father than teh specs say teh 301's should with the original 15's (which were tuned for more power handling at the expense of deep lo end) What I think I would like to do is in some way slightly reduce the tweeter level relative to the midrange ... suggestions? These have the tweeter-protection thing on them

Apologies if this is better covered elsewhere... have a pair of kp301's bought new in box ages ago. 5n transit one cab tooka drop to concrete and had its woofer magnet shifted, trapping the VC. I Replaced the woofs with some (i believe) LaScala woofs that have a different impedance and so messed up the crossover and sonics. Fixed that by rewiring the crossover and NL4 connector for bi-amp operation and they have served well like that. Haven't used them in some years and am getting them back out. System is a CARVIN 4x200w power amp and a Peavey electronic xover. Do I gain anything by damping the interior of the cab with fiberglas?
