You might also consider a TQWP/TQWT design. I've got a pair of the Dayton PS-220s (I think that's the right number) TWQPs in the home theatre, and they do quite nicely. You're welcome to come out and hear them sometime, I can easily put them in the main system.

Thanks very much for the kind offer to hear your TWQPs. I'd like to take you up on it. Where do you live?
My understanding of that type of enclosure is limited to what I've read on various DIY sites, mostly referencing Martin King's work. I haven't built any yet. Aren't they designed to extract all the deep bass possible, or are they also useful for midrange? I've got plenty of bass with my sub. I don't NEED to use a sub if the mains can produce enough bass, but I don't think there is much chance of any 5" driver doing that. Whatsmore, I found that my current speakers sounded better, especially at high volumes, when I eliminated the lowest frequencies from the signal. All remaining frequencies were clarified and the soundstage tightened right up.
When i started this thread I was thinking that my enclosure was probably not the problem and I needed a whole new speaker system. Perhaps I just need to try a new enclosure.
I looked at some of the Onken designs awhile ago. Planet10 designed one specifically for my driver, called the Fonken-steen:

If I use a 2nd order crossover I might attenuate the lows from the Fostex enough to gain the clarificatoin and soundstage benefits mentioned above.
