Hi, Al,
This is one of the concerns I had, or at least one of the things I was wondering about, regarding the X5s, how simply raising or lowering the volume on the powered woofers would affect the quality of the bass, whether controlling bass output by adjusting the decibel level would have an adverse effect, going in either direction, on the musicality of the bass and its integration with the other drivers. Sorry. Long sentence. Hope it was clear. The X5s I heard were barely out of the womb - I think they had 10 hours on them - and the bass from them, while impressively extended, was a bit boomy and seemed to ride under the mids and highs rather than join in with it, like oxpeckers on the back of a hippo. This was due in part, no doubt, to the room, probably in part to not being broken in, and in part to my being a nitwit and not thinking to just turn them down. I was heartened to hear you say you get balanced, natural-sounding bass. I listen primarily to jazz (west coast, hard bop, for whatever those sadly insufficient categories are worth) and classical (smaller ensemble, symphonic, and a lot of opera), neither of which are terribly demanding in terms of outright bass power, but bass is about more than just the depth and extension of a given note. Done right, it both supports and informs the music with texture and solidity and richness, fills it out, puts meat on its bones, pick your abstraction or metaphor. This is why I wondered if simply turning the bass down would rob the music of some of that essential underpinning and nourishment, or if turning it up would overwhelm it, make it fat. It seems you've solved that problem with room correction and treatment. While I'm amenable to both, I have neither and am loathe to think I would need both to make the X5s, or any speaker, work. I suppose you have to pick your poison. You either live with the bass as it's manipulated by your components, your passive speakers, and your room, and call it a day, or you take the offensive and get bass you can at least somewhat self-determine via a powered woofer and room correction. It's a conundrum. I'd like to think I could set the X5s up in my room and, turning them up or down as needed, have good, tuneful, genre appropriate bass, without any other muss or fuss. Probably a pipe dream, but I'd sure like to know if anyone has had just that experience. Thanks.
Josh
