I got them from the original owner and they even came with the original boxes. They are the grey utility cabinets and are all original, though I wish they were in wood veneer . Because they needed foam surrounds on the cone drivers, I never got around to hooking them up; instead I tweeked my Klipsch Khorns and continued to build around the Khorns. Out of the blue, I decided to refoam the drivers and give them a listen. I substituted the 4343's for the Khorns in my biamp setup where I use a Crown DC300 on the LF and a pair of Marantz 9's on the HF's along with a pair of Heathkit XO-1's for the crossovers and a pair of Dukane Ionovacs to supplement the HF's. Though I loved my Khorns, hearing the 4343's sealed the deal for me as to which pair of speakers I decided to go with in the future. I was amazed and could not believe the reveling nature and detail combined with the smoothness of the 4343's when combined with my other gear.
Now that that is out of the way, here is my quick question. Based on my reading of some threads in connection with the 3143 crossover network, the threads seem to say that in bi-amp mode the crossover caps are eliminated from the network. Is this a correct reading? Though this seems counter to my understanding of the schematic, I readily admit I am a novice at these sort of things. If this is indeed correct, I see no sonic benefit to replacing the caps if one intends to bi-amp. Is this correct logic or I am I missing something (as is most likely the case).
