Had mine for a little over a year now. I think I was one of the first owners and I think it's my 21.0 (in Santos Rosewood) that's pictured on the website.
I couldn't be happier and can't imagine finding another subwoofer that's better either in terms of sound quality or aesthetics. It has all the power I'd ever need (and then some!) and even at room-rattling volumes there's no hint of distortion or strain. I'm using it with a Legacy setup (Whisper XDS mains, Marquis HD center, Expression surrounds) in two different configurations: for movies I use the Audyssey on my Marantz processor with all speakers crossed at 80Hz. For music, I prefer to let my Whispers play with the 21.0, though I had to manually dial it in via the Xilica processor that comes standard with the Whispers. Reason being the Whispers subs can clip on bottom-heavy movies, so I let the 21.0 do all the work, while on music they do not, and I think the added subs help even-out the overall response with even less distortion. Even with the most demanding modern films: War of the Worlds Pod Emergence, Tron Legacy, Edge of Tomorrow opening, etc., the 21.0 provides completely effortless power; and, yes, I'm one of those idiots that tried to crank Edge of Tomorrow only to find myself reaching for the volume control as it started to freak me out as it hit those lowest registers!
Personally, I'm more of a critical listener when it comes to music than movies, mainly because I think film is more of a visual medium and I watch a lot of old and foreign films where sound isn't that great to begin with. With music I'm one of those weirdos that actually listen to pipe organ music where it's not unusual to find heavy output under 32Hz. I've never found a system that could replicate the visceral feeling of organ music well until I got the 21.0. On a recording like Saint-Saens Organ Symphony with Guillou and De Waart conducting the San Francisco Orchestra
, especially in the slow movement it's amazing to feel like you're floating on clouds of sustained sub-bass output while the orchestra soars over it. On the other hand, on recordings like Felix Hell's Organ Sensation
the 21.0 feels like a demon intent on destroying you and the house! In a more pop/rock vein, the 21.0 made me really appreciate the textures of a band like Massive Attack, or albums like A Perfect Circle's The Thirteenth Step.
Not sure if I can heap enough praise on it, but, to summarize, the 21.0 has transformed both my film-watching and music-listening experience completely while looking drop dead gorgeous to boot. I can't imagine anyone being disappointed in it. Here are my measurements if anyone is curious: https://www.avsforum.com/forum/113-su...l#post35963746
I'll try to get some pics later. Been meaning to do that for ages anyway.
