I hate to try to highjack a thread as a LONG time lurker and first time poster, but I can lurk no more. I've been doing some serious lurking lately and am planning to build a pair of subs. Basically 2 vertical marty's with single drivers All the usual suspects seem to be on this thread and I was hoping to solicit a few opinions before I start chopping up my lumber tonight. In hand I have 2 ultimax 18's and a inuke 6000dsp will be here this Sat. I'd like opinions on which end of the spectrum to chase. I've designed 2 separate boxes in winisd and now need help.
First a few things that I think are most relevant. My mains are klipsch rf-83's which "should" respond down to 29hz, but at what spl I don't know. I have no measuring equipment yet. My room is a multiple purpose theater room that is around 6000 cubic ft. with the majority of the room having a vaulted ceiling with 4/12 pitch going from 8' on the sides to 12' in the center.
design box 1(red):
12ish cubic feet tuned to 15.5hz
1300 watts to keep excursion around 22mm
design box 2(green):
8ish cubic ft tuned to 20hz
2000 watts for excursion around 22mm
Which slice of hertz pie do I want to eat? Listening is 90% movies and 10% music. No WAF factor for the boxes and will have a several options for placement around a 22x25' room.
Clearly given my room size, a bass head may suggest 4 or 8 or 16 subs, but these 2 are it (for now
Any assistance would be appreciated. Please let me know if I left out any variables.
