I have made two LLT subs (nett Volume 20 cu ft) tuned to 13 Hz, each with a 18" Maelstrom driver powered by a Behringer iNUKE NU6000. Not in use yet, hopefully in a month. They are situated between LCR. It's a 5,000 cu ft space, hence ample woofage is welcome.
There's a spot available on the right wall lower 2 feet, 13 feet wide. Or I make 18" thick bass/broadband absorbers there, or... extra subs! After deduction of pannels, braces, driver and port, I reckon to have a total of 26 cubic feet nett Volume there to play with.
Several options come to mind:
two 13 cu ft LLT each with a single SI-HT18 D4 powered by a NU3000
two 13 cu ft each with dual SI-HT18 D2 powered by a NU6000
one or two smaller subs each with one SI-HST18 powered by a NU6000
The advantage of the last option is there is some space left for absorption. Not sure how low the tune would be. First option is closest to the spirit of the existing LLT. Second someting in between...
13 or 15 Hz tune would seem ideal.
Edit, I am a bit stressed on the depth. Therefore the HT18 (14") would suit me more than the HST18 (16"). Could still do two or four 4 cu ft sealed subs with the HT18 ofcourse.
Sonotubes are not an option. These are cool, but I want a low shallow build.
It's the room, stupid!
