Finally bit the bullet on a pair, over a decade later, and was looking for some tips/suggestions.
I read a posting on a guy who upgraded the internal wire and swapped to an Infinity Reference Woofer (his website with photos I think is long gone and no longer on the net)...I've read debates about bi-wiring vs bi-amping vs bypassing the internal crossover altogether. I currently bi-amp a pair of modified Infinity CS-3009's, the Circuit City variant of their Kappa's, with a Citation 7.1. I had experimented with bridging the amp and bi-wiring, but using the 4 channels in a bi-amp config worked best for me. I suspect I shouldn't bridge the Citation 7.1 or 5.1 to feed the AL-III's, as that may push the limits, but I may experiment a bit with the 5.1 bridged and not bi-wiring, let the crossover work.
What's the current line of thinking as far as upgrades / modifications...from the simple to the complex? I suspect the 705x, even dedicating 2 channels to each individual speaker doesn't have enough guts to drive these. Anyone ever paired a Citation 5.1 or 7.1 amp? I believe Bob did a little EQ adjusting with the crossover and I while I have no fear of refoaming a woofer surround, I could see the value of potentially refitting a Kappa 10.1 or upgrading the internal wires to something beefier. It looks like the newer Infinity subs aren't as efficient and have different enough specs not to work (1050's on up). Or has someone had success?
But, perhaps the science of the AL-III's are beyond me...they look and sound like magic...and maybe it's not a good idea to go under the hood too much.
I know, high current (lots of amps and watts) to feed these guys. Just curious to hear what others have hooked up to their AL's....what if any modifications are kind of the norm...or if I should just enjoy them as is. The guy I bought them from had them hooked up to Pioneer receiver...so, I'm pretty sure I don't want to replicate what he did.
