I am thinking about putting together my first DIY subwoofer. A sealed enclosure looks like a good one since its hard to mess up too much, don't have to worry about tuning and some other things. I found a nice speadsheet from diysubwoofers.org to plug in differnet speakers to see what they'd look like. This rls15 really got my attention!
If the speadsheet it right and I understand most of it the the performance of this element in a 10 cubit foot enclosure rocks! Because the Qts is very high (0.953) to get things to work out I needed to plug in a 1.09 for Qtc to get SS's recomented box size and everything to work out. Here is the graph I got:
Is this correct? This looks really good to me. Is it? With the SS element saying it can use 2000 RMS watts, a bridge Behringer EP-2500 would work really well with it too?
So how am I hoping to use this? Well it is from media room, lots of casual TV watching, some serious movie watching and some gaming. The room is 20x20x8ft in my basement. I ussually listen to movies between -10 -20db below reference. The other reason I am hesitant about a LLT or a ported design is I am in a end of unit townhome. I think being in the basement 7ft under gound level with 3 concret walls helps me not bother the neighbor too much, I don't want to push my luck with alot subsonic frequencies.
What advice do you guys have for me?
Thanks!
