We posted back and forth last week regarding the above. You mentioned a nice option of a large basshorn cabinet to acheive 20 Hz and hopefully 108 dB efficiency to match well with Oris horns (160 Hz 1st order crossover).

O.K. then, here's your chance to help design my sound room. Please send speaker plans (cabinets, driver specified, etc.) and optimally fit them into the room.

Any additional design features (already considering dedicated 30 amp circuit using 10 ga. wire; Golden Ratio room dimensions; absorption/diffusion at 1st reflection points between speakers and listener; and back wall set to a slight angle) would be great!

I would stipulate 8 foot flat ceilings with a loveseat and desk/office chair behind both in the sweet spot.

thanks tons.
