Other than general terms, I don't see manufactures discussing the synergism their products create when in a room full of active speakers.
The synergism you speak of can be achieved with just about any subwoofer out there. A manufacturer can talk about blending, synergy, harmonious integration, etc. all they want however it's up to the end user to expend the requisite effort to achieve this. This effort requires not only the expenditure of time, but the necessity of learning how to measure and interpret. It's dependent upon your ability to have the freedom to move things around. It's dependent upon your ancillary equipment. Synergy might even be improved if one has the financial means to purchase a smarter processor or even additional subs. It's like taking a one or two semester course where you have to work.
Some manufacturers, Seaton come to mind, will assist you either here, their forum, or by other means, and he has pro bono. But there is a limit as to how much time a manufacturer can spend with one person after all, they're not giving you the option of a one year, 6 session, support rider. That's where forums like this come in where you'll find people who are willing to give of their time to assist you. No different than if you have a problem with Microsoft Access and can rely upon forums and newsgroups to help you figure out stuff. Figure out enough stuff and then maybe it'll be use who starts tossing out nuggets of wisdom.
As to crossing over from home theater into music, that's a yes/no answer. It's going be based on room acoustics. Everything I've seen and read so far says, for the most part, "ALL" subs are the same. Others will be upset by this comment but that's their issue to deal with, not mine; box, Amp and emitter with variations of the theme; poor integration into room acoustics.
With all due respect that's the individual's problem and even with just speakers there are issues one needs to address.
For the first time, I saw in the Martin Logan design, a subwoofer that spoke to my design concerns. And no, there's nothing cheap about the Martin Logan but what the design tells me, it tells me for the price, I'm actually getting something worth buying. That means everything to me. For the first time, I'm salivating over a sub and that's never happened.
Subs for the most part don't come with the most attractive finishes or even options for better finishes. It's going to cost money.
