Thanks for all of the responses so far.

Chris, you definitely have me looking beyond t-line cabinets. Given that I don't currently have any sort of shelf where the speakers will go, I'm still open to floor standing (hence, t-line) so long as the foot print remains small - otherwise I'm probably looking at stands if I end up w/ book shelf cabinets.

Re. position: my floor plan pretty much sucks for audio and I can't get the speakers more than a foot or so from the nearest wall (one is in a corner in front of a window, the other next to a doorway); listening position is against the opposite wall.

Re. crossover: I understand that a higher crossover generally makes things easier on the FR drivers but I'm not clear on what is actually problematic about crossing below 80Hz given that many FR drivers have Fs and F3 near 50Hz (eg Alpair 10.2). The whole point of a t-line cabinet is to take advantage of the bottom end of a FR driver.

Given that Chris put his FRs in 2L boxes, I suppose I could put the subs in t-lines and end up w/ floor standers.

Re. AN 15" - size is definitely a consideration, also not up for investing so much in the drivers for my very first project. I am open to co-axial although it does entail another xo which I'm not crazy about.

And lastly, Oakenfold, Digweed - good to know we're on the same page

Overload the room and sound, well, not good at all. And the size of a cab for the AN15 (or even the smallerones) would eat up a lot of floor space.

Chris & Zia areon the right track IMO, where the system needs to pump is in the mid & upper bass. A good 8" midbass (or a pair of 6 1/2), with a small FR xoed 160-400 Hz (active prefered) should kick butt... my room could fit about 8 of the OPs rooms in my room and anyone who has heard Sinead's Vampire with the woofTs (or the FonkenWoof) could extrapolate how well they would do in such a small room.

Based on my experience (limited compared to Dave's, I'll admit), you can use "mini-subwoofer" drivers for the low frequencies.

You gain some low end grunt over the average (similar sized) mid-bass, but extension higher up suffers. IMHO, if it'll get to baffle step frequency (500Hz for me), its high enough. But I use steep (4th order) active crossovers which allows me to get rid of the nasties in the woofer's higher frequency response.

If you plan on using active crossovers, I'd consider a pair of these per side. You could mount them for force cancellation (ie, mounted on opposite faces of the cabinet) to prevent vibration travelling through the floor.

Re your point on crossovers
I understand why people put FR drivers in transmission lines. The point here is that you can get more low end extension, more overall output, and lower distortion by using a woofer to cover the range that the TL would take care of.

Chris

I know. It sounds bloody awful. Many years ago I use to practice playing my bass guitar in my bedroom it was a single 15" cabinet, it sounded absolutely crap everything would shake and vibrate even at low volumes.
I never play bass through 15s anymore they don't sound as good as multiple 10s. Just much better tone and dynamics through multiple 10s.

Anyway that brings me to an idea, I really love the idea of the Ambience enclosure that Audio Nirvana publishes, that is 2 fullrange drivers per speaker one in front and one on top.
I think this would work really well for the seas full range or the Audio Nirvana Super Cast Frame 8 (or even the 10" cast frame).
I built a 1.5 way for the Seas full range and it worked really well. I think the Ambience enclosure is better because it does away with an inductor for the same effect.
