There is another option,
ARound 5 years ago, another Eminence CX10 build was going on but it used the giant 6 pound PSD2013 beast compression driver from Eminence. This allowed the crossover point to drop from 2 KHz down to around 1450 or 1,500 Hz. Since tens start beaming at around 1500 or 1600 Hz, they went with the beastly compression driver to tame that issue. There are two versions, an 8 ohm or 16 ohm but very interesting results. Post 228 shows the 8 ohm version in room (with room correction I'm assuming--theya re mounted on the rear walls)
Post 163 os wotj tje 16 ohm version--he did state that the dip at 5 KHz on axis was not as pronounced as when he took off axis measurements--not sure why that dip is there or how he screwed it up. The off axis measurements are both higher in SPL in that reagion and smoother--that gnerally won't happen so I would count the on axis dip there to be a measuring error. The designer of the 16 ohm version of CD uses a diffferent crossover than the 8 ohm version and he uses them as near field monitors. An interesting option and it includes off axis measurements
This year is my surrounds build, I left them for last.
I am seriously thinking of going with the 16 ohm veriant in a sealed box for several reasons. What kind of idiot would use an 85 watt RMS titaniam compression driver made for stadiums in a surround speaker? THIS guy!
Actually, I always wanted to play with coaxials and would try them out for outdoor parties fed with around 200 watts of PA amp to see how wide of dispersion they go. That way my wife can proclaim me the villiage idiot because those are "surround speakers".
Actually, I don't think you could damage them with AVR power even without a suboofer because of the small sealed box protecting them from over excursion--be next to impossible hurting that monster compression driver also. The perfect "idiot proof" speaker? I dunno, maybe they would be the hot ticket for folks that live with people that like to turn it to 11 and rip off the knob. This way it can be positioned in any way--being coax it don't matter so even my idiot brother could not screw it up. Figure if my brother wants a short center, the CX10/PSD2013 would give him something 12 inches tall when using birch 1/2" ply heavily braced and no worries about "timbre matching" with the LCR and surrounds all being the same speaker.
I will start my build in about 2 months--even the villiage idiot does not do woodworking in freezing weather.
On a side note, I did ponder using HTM-8's but I know I don't have full control over their end location for the next 30 years so coax would seem to be the best option. Never know, they might be idiot proof and this idiot will find out! Good luck in your question for surrounds, the above is just another option to muddy the waters in your selection process. Enjoy!
