Subwoofers that do both L/R & LFE simultaneously?

REL Strata III have another advantage in the sense that they are sealed enclosures which integrates well with any speaker in the chain. I use it with the LS3/5a as well as Kef Reference Two, both totally different speakers yet the REL seamlessly integrates with both and sounds superb.

I reviewed it earlier at A'gon for those who like to read it:

I like the way these sound.

Sorry, Nsgarch. I thought you were implying that the signal was rolled-off (via a low-pass filter in the sub) before being sent to the main speakers. As you know (but for those who may not) this is not the case with the REL. The full bandwidth signal is sent to the main speakers, and a "sampling" of the signal (via the 100K Ohm impedence of the sub) is sent to the REL to be low-pass filtered and amplified by the internal sub amp. The REL is then adjusted in terms of amplitude (volume) and crossover frequency to integrate with the natural low-end rolloff of the main speakers. The REL doesn't use another set of speaker cables (although you could make a Neutrik-terminated cable out of a speaker cable). A supplied cable is included with the sub (but you can find reasonably-priced aftermarket cables, too).

Can someone describe this Neutrik connector is detail? How many connections? You just slip it under the amps speaker outs on either the L or R channel? Can you use two subs? It does sound like something that might cause a different set of tranference conditions in that channel possibly negating big buck cables. Thanks for all the unput!
