I need to place a subwoofer, maybe two, in my stereo setup--music only--as my room is killing the bass from my floor standing speakers. Setup: Bryston 4BSST2, B17, BDP2, BDA2, Dali Epicon 6 speakers.

The dealer that I am working with offers Aerial, Paradigm and Velodyne subwoofers. He is recommending the Aerial SW 12 sub as the best solution, in part because the Aerial has a dual crossover configuration that allows it to meld with my Dalis better (just quoting the dealer) than the Paradigm S1 or the Velodyne Digital Drive 15+, which do not have dual crossovers???

Do dual crossovers improve a sub's ability to seamlessly integrate with floor standing speakers?

Are there other construction elements or components one should consider in selecting a a sub(s) that:
1) improves the sub's ability to integrate with stereo speakers?
2) makes the sub easier or more flexible to place in a room?

As in real estate the primary thing is location, location, location. Two, properly located, are better than one for an overall smooth response in the room, but location is the key whether using one or two. Your speakers are rated at + or - 3 dB at 35 Hz. Don't know whether that is in room or anechoic but it should not be difficult to integrate a subwoofer(s) with those speakers. I'm a bit biased, but I would spend some time optimizing the location of your speakers for bass response and use room treatments to optimize the sound quality for two channel music listening rather than investing in a subwoofer. The Dali's, properly located should produce sufficient bass in most rooms unless you are really into pipe organ music and similar fare.
