Hello all-
What I have:
Dayton RSS315HF
SA240W amp (18hz 2nd order rumble filter)
~3 foot length of 20" Easy-Pour tubing (1/8" thick walls)
Precision port 4" x 17"
What I'm trying to do I figure out what the heck size to make my enclosure. I read on a forum that PE recommends a 3.5 cf box (100L) tuned to 21hz for the Reference, so that is one of my options. The issue is that it seems like I might have room gain issues above ~20hz, since I don't get rolloff until that point.
My other option is to get my response looking similar to the LLT Sonos I see built, and I think 154L @ 18hz does the trick, especially with the rumble filter in mind.
Excursion in the 100L box is at 11mm Xmax, out of 14mm. The 154L takes full advantage of the Xmax, right at 14mm at 240w.
I can't accurately say what room gain will be like because I'm moving out in 6 months or so and don't know what the room will be like. Sorry for the ambiguity, but I haven't really figured out the best plan for this driver yet. The modeled curves are attached. Note that the Unibox curves are without the 18hz 2nd order rumble filter.
I know uncertain room gain is a huge issue, but I'd just like opinions as to what people think is the prettiest all-around curve.
Thanks!!!
