CEILING SPEAKERS
These guys sell KEF, Visaton, and sonance, mainly designed for in-ceiling use.

The cheapest way is probably to buy a secondhand pair of KEF Q35 say? off ebay and discard the cabs. Free XOs to play with too.

Do you like dual concentrics?

Stereophile: Tannoy Churchill loudspeaker

http://stereophile.com/images/archivesart/tanfig7.jpg

John Atkinson:"In the time domain, the Tannoy's impulse response (fig.6) looks typical of a design that uses a high-order crossover. Indeed, the step response (fig.7) confirms my suspicion from the impulse response that the Churchill is not time-coherent, despite its use of a coaxial drive-unit that places the tweeter diaphragm close to the acoustic center of the woofer. The tweeter output arrives at the measuring microphone first, followed by the woofer output."

Wow those new Ciare Coaxials look interesting! The 10" especially

Tannoy have a constructor series or some such name for in wall or in ceiling speakers of smaller size. You can buy these and pull the driver and the xover.

I heard the tannoy dual concentric in a voight pipe at a diy speaker contest. Sounded quite good... it definitely had the coherence of a good full range driver. Produced good amounts of bass too.

The drivers were obtained from ebay... like James says, you can buy the ceiling speakers and pull the drivers from there.

great thats some leads for me to start following!

I would go FR but.... I have never liked the sound of the HF on any ive heard, esp above about 7k, and esp when cranked up LOUD. I figure this is the best compromise for me.

Thanks all.
