Rel Sub Woofers..Any Experience

One of the great things about the REL's is they are very easy to integrate with any system and any listening room. They operate with your speakers. They can be adjusted at 1 Mhz intervals. There is no crossover between the preamp and power amp cutting off and or changing the signal to the main speakers. The high and low inputs can be adjusted, and both be set up so you can easily switch from Audio (high input) to Home Theater (Low input) if you have a dual purpose system.

REL's also have "Balanced" inputs.

I have a pair of Quest Zs & have tried several subs & the only one I could get to seamlessly intergate with them was a Stadium 2.

Correction: The adjustment to REL's is actually 2 Mhz intervals on my Storm III

One cautionary note: RELs appear to not work well with certain amplifiers (dual differential I guess it is), such as my Pass X-150 and I believe most of the Krell amps. Special wiring configurations are recommended, but I could never get a satisfactory result with my amp and just punted on the REL. Perhaps I should have punted the Pass instead, but that's my story. Never could get a good explanation from Pass or REL, though they tried and I suspect both think I'm nuts, which may well be true.
