Rel Sub Woofers..Any Experience

I have CLS's (full range esl's) and listened to the Strata in my system. Really good integration and, surprisingly, improvement in imaging which I did not expect. I'll try the Storm next. IMHO, this is the ONLY sub that can be matched with ML esl's. So far as hybrid speakers like yours, I have no experience. REL is the only way to go with my speakers, though. You might give the Vandersteen a try -- not up to the standards of the REL in my system.

By the way, talekd to the folks at ML recently. They are close to bringing their own sub to market. They are pointing to the home theatre market (with ML hybrids) so I'm not sure how this will sound in a pure audio environment. Nonetheless, this is being designed around their current speaker line. Supposed to come out early next year as I understand it. You may want to contact them for more info. Really helpful people.

How do Rel subs compare to Hsu Research VTL-2? I also own Martin Logan speakers

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.
