and the side walls ?

anyway, if your room really is small, forget about big speakers
big woofer, ok, yes, will do
but for a midrange you would need something much smaller
good 5" on a big shallow waveguide would be very nice

Alternatively you could buy some Tannoy DCs off ebay.
They'll work in any room big enough to fit them in which, I suppose, would be equally true for other co-axials.
Currently there are a few 12" 3142 drivers on offer and one guy is selling 4 Pumas (15" DCs!) for 800, no bids and one day to go!
You could sell one pair and use the proceeds to build something like these:
tannoy or even use 18" instead of the extra 15" woofer.

I think the main problem still exist, with any big drivers, coax or not
the 'forward sound tendency' needs more space to get did of the aggressive 'in your face' sound

I got the gist that JRKO is after an 'in your face sound' but the apparent sound source with Tannoys is about 30cm behind the voice coil so you'd gain a bit of virtual space.

Either way I never had that problem with my own Tannoys, they make excellent near-field speakers and that is my preferred way of listening.

That is the general symptom of too high directivity at high frequencies.

There ought to be enough of early room reflections to cure this nasty illness.

I've been down the Tannoy DC route. 10" Eaton & 15" Berkeley. Fun while it lasted

Not really in your face. Describing sound is tricky. I want to be able to play at realistic levels should I wish, but will be lower much of the time. I want a double bass to sound like a double bass, a violin like a violin and Alison Krauss to sound like........well you get it. Pared down music to sound open an haunting and live recordings to sound live. I know a great deal of this is down to the recording but if its there, I want to hear all this at ANY volume level. I guess glossy hifi mags would call it 'resolving'?

you will need lots of power, and bound to be a multiamp setup

efficiency ? 95db woofer with 92-93db mid will be very good
