Speaker choice without need for deep bass

@jbuhl Quad S4 might be cabable, but a single 5 or 6 inch low/mid driver may not cut it. The 6" in my Epicure 5 certainly don't. Hence the desire for 2x 6" low mid.

ghdprentice: "wrong direction"? Maybe. But my testing/experience showed significant improvement in almost all relevant categories when I added the powered 18" sub (replaceing two meager 10", and then my great Velodyne DD15, now in use in the 2nd system), and later 'cut' the main speaker/receiver off at 50 Hz. Note: the main speakers were B&W Nautilis 804.

Having 'no need' for very deep bass frees up the main speaker design from huge cabinets with big volume to facilitate the huge woofers and the required massive air volume. Ergo: smaller, less complex speakers are possible. And that has already been accomplished. And I could rest. BUT, if I want to listen at elevated (call it 'live') souid pressure levels in my main room, it seem a single 6" inch low/mid even cut a 80 Hz is 'getting it done'. 

Aside from that: price has obviouisly nothing to do with the issues, since that is relative. If the budget were $10k, your (potential) answer would be "you need $100k to get even close to a decent system", just when the next guy chimes in "no way you can put a real quality system together for $1000k (thats a cool million). 

And yes, the 1.85 mio (just speakers and main amps) system I listened to extensively a few months ago (Sonus Faber Suprema, 4x Burmaster) was impressive for its absolute performance level, but it never measured high on my 'impressive' scale, because I have heard systems for 1/100 of the investment (not to speak of another mio to build a house with a suitable listening room) that were not THAT far off,  lol. 

it's not going to work INHO simply because bass isn't just bass. It' s not LEGO. You can't skip low frequencies and expect good sound by adding a sub or two. It won't produce full range. Sub is addition not completion. It has to sound good without the sub(s). There are lot of choice mostly used for a 1000. Arendal, Polk, NHT, Dali, Canton, Wharfedale, Q, Klipsch all have floorstanders that may work well.

Would Mofi Sourcepoint 8 be too big?  That should do it nicely with a powered sub in a larger room. 

@gano: Like I said early, I already prooved that it sounded better (when cutting under 50Hz off the main), so that is NOT a discussion point for this posting. 

With no need for large woofers to handle 20 Hz, there is no need for 3 or more way complex system (and large ugly boxes). Small/slim design should also help. 

Only what (non full range) speakers can handle 50 Hz and up range for a VERY large room. 

Also not the question: what speakers can handle 50 Hz and above at low to medium levels in a very large room. 

Or maybe I should put it even blunter to avoid side tracked discussions: 

Are there any good 2 way speakers out  there that have at least two 6.5" or similar low mid drivers (required IMO to 'feed' the very large room)?
