My main left and right speakers are two way, and so is the center. Ignore that little supertweeter on top of them in the pictures; I used to have them crossed over with a single capacitor to the JBL supertweeter at 11Khz but found they caused more problems than they solved. So, what I have is my left and right are two way and crossed over at 1,200Hz. The cabinets which you may recognize are Altec Lansing A7-500s (!) that have been pretty heavily tweeked, since I used to work for Altec as an electronics engineer, and had full access to all their resources. The center has the same Altec Lansing high frequency horn and compression driver, but it is crossed over at 500Hz to two flanking 12 inch woofers. The crossover for this speaker is before the power amp and is a passive L-C type which feeds a stereo McIntosh MC240 tube amp with one channel for the bass and another for the highs. A passive crossover at line level is a completely different animal sonically than at speaker level. It is much more precise, and since the impedances are higher, more reasonable values for the capacitor and inductor can be used.

I have been tweaking this system for 20+ years!!! I have always used electronic crossovers for the mains, but different crossover slopes and different frequencies. Active crossovers are essential for these speakers, or they can sound really bad, which is why some people are astonished by my use of these A-7 speakers (they have a bad reputation mainly because of their horrid stock passive crossover, un-damped high frequency horn and flimsy cabinet). To answer your question, yes, I am very satisfied with them at this point.......until I think of something else to tweak
