OK, I feel like I've wandered thru the desert here for quite a while. Can you tell me what you use to predict in-room response and power requirements? Ie, what would lead you to your conclusion that one would want X-15" drivers and at least Y watts each?
Alternately, I'm happy to take an empirical recommendation. My room will be the upstairs of a story-and-a-half. Overall width 23 feet between 5' kneewalls. Ceiling side slope at 10:12 pitch, resulting in about 11 foot wide horizontal ceiling at 10 feet high. Room length 40 feet (unless I forego dedicated listening room at the end, in which case it becomes 60 feet). So that's roughly a range of 7,000 to 10,000 cu ft.
My mains are flat to 23Hz so can take a bit of the load, but anticipating at least 8-15" drivers. No idea how to estimate power requirement. Want it capable to hit reference level, but never play it that loudly.
Could you recommend, or point me to appropriate modeling software? Thanks! Tim
Most people consider this place an oasis not a desert.
You can model the anechoic response with any box modeling program, just enter the largest box size the program will allow. Unibox 4.0 is as good a freeware modeling program as there is. It uses Excel. If you don't have Excel then use WinISD Pro
As for modeling room gain there freeware programs to model that as well, all the ones I know again use Excel. Just do a Google search for FRD Consortium and look on their downloads page.
