I am going to interrupt DMark's posts to say that I was fortunate enough to be at his house when the Legacy Focus SE's showed up. I helped him set them up and then I participated in the listening session. I previously had a set of Strata Mini's, which had planer magnetic/ribbon midrange/tweeters. I loved the sound of those drivers. Unfortunately, they didn't have enough SPL output capability for my system, and I ended up moving on from them. The Legacy Focus SE's had all the same sound quality of those Strata Mini's, but *much* more output capability. And they retained that same sound quality right up to the loudest levels. In addition, the dual 12" woofers belted out bass that was intense, tight and articulate.
Dennis initially set up his system with one of his Studios as the CC. It quickly became obvious that, as good as the Studio is, it was clearly out-classed by the Focus SE's. We ended up listening with a "phantom" CC as the Focus', (Foci?), did a better job of generating a believable and focused central image, with a perfect timbre-match and equivalent output and bass extension.
We also spent a lot of time playing around with using Bass Management with Dennis' M&K subs vs. running the Focus SE's full range. The SE's had flat output to 30 Hz in Dennis' room and they actually had more output than the subs down to 30 Hz. However, below 30 Hz, they fell off pretty fast, typical of a ported speaker. In fact, within their limits, the sealed subs had deeper extension than the speakers, and they had flatter FR, given their ability to be better placed in the room than the large floorstanders. Overall, though I loved the bass output of the SE's, I preferred the Bass Managed output of the subs, (up to their limits, which were lower than the speakers!)
Bottom line, for me, the Focus SE's are fantastic speakers with incredibly believable and realistic midrange and high frequencies. The imaging and soundstage are as good as anything I've ever heard, with phenomenal detail, transparency and articulation. I, (personally), prefer a system with the speakers crossed to subwoofer(s). Therefore, I would not opt for a speaker with the kind of bass response the SE is capable of. I would prefer a speaker with high output capability to about 60 Hz, and then send the bass below that to subwoofers that are properly placed and EQ'd to reproduce that bass.
For a 2-channel system with no subwoofers, the Focus SE's would be hard to best. They will reproduce almost the entire audible range, (30 Hz and up), with fantastic realism, impact intensity. If I were looking for a "full-range" 2-channel speaker, my search would be over.
