Gradient Revolution

The only experience I have with this speaker is hearing the active version at two different CES shows. In both cases they were set up in small rooms, with the speaker quite close to the walls. In fact, one room was not much larger than a walk-in closet. Given the limitations of space, these speakers sounded fantastic. They were certainly one of the most memorable piece of gear at the show.

The person running the demonstration explained how the bass cabinet of the Revolutions can be turned to change their radiation pattern to fit different set up conditions. This explains how they could be set up in such bad rooms to sound quite good.

I don't know how they would compete against other speakers in their price range under optimal conditions(my guess is that they would still be competitive), but I doubt that there are many better systems where one has to deal with tough setup conditions (close to wall and/or corners, etc.).

I presume you read the recent TAS review by Robert Greene. He took some measurements of the Revolution that weren't included in the article, but are available on his website. You might find them interesting:

The first Revolutions I heard were actives at CES 2001 (if memory serves me). They used three bass modules per side, and I thought they had the most natural-sounding bass in any room at CES (including rooms with speakers over ten times the price). I didn't hear any colorations from them elsewhere either. Several months later I became a dealer. I never had the actives, only the passives. In my experience the passives like a very powerful, lively solid state amp. I don't presently have any, and from what I understand the mid/tweet coaxial unit was updated about a year and a half ago.

i,ve just heard the passive version at my dealer showroom in Mexico. The most impressive trick they do is that you can identify very clearly the pitch in the bass lines due to its dipole boxless design, it is almost revealing. They don,t have a "cinemascope" soundstage like some that you hear a guitar 6 feet tall, but rather a real one where you can distinguish real proportions. Its a pretty neutral speaker and altough I understand it is most commonly mated with ss amps I heard it with a Jadis 60 watt p/ch tube amp working very nice specially with jazz & chamber music. I,m looking forward to hear the active version which should be a tour de force by using tubes on top and ss in the bottom. Although they just went up in price (from $5000 to $6300 for the passive), I think they are very competitive taking in account what they do with others in their price range, and most likely will be getting them in the near future.
