I just purchased a 15" Avalanche on special and I'm trying to figure out what enclosure I should put it in. I will be using this sub for 75/25 HT to Music but I don't want the music to suffer. Generally speaking I like the sound of a sealed enclosure but then again I've never heard a really well designed ported system.
The listening room in my apartment is ~15'X12' with an 8' ceiling. The room does however open up into the rest of the apartment on both sides so the total volume of space is about twice that maybe.
I was thinking of trying for a small sealed sonotube and try to stick to the recommended 2.2 cu/ft that I've seen posted on AA's website. By my calculations that would give me a sonotube that is 15" tall with a 18" diameter. This seems like it's pretty small to me which isn't a bad thing (actually a pretty good thing :T )but I just wanted to make sure my calculations were correct.
I was planning on driving it with a Behringer EP-1500 that puts out a claimed 1200 W at 4ohms bridged. I am also planning on getting a Behringer DSP1124P to help equalize the sub since I'd like it to still go real low for HT duties and room placement will be somewhat limited.
So I guess what I'm looking for is feedback on what I've got planned so far and possible alternatives. My main areas of concern are:
--Is this amp overkill for my application? If so what would be a better amp of choice in the under $250 category. Fan noise isn't a huge concern because I'm planning on replacing the fans with quieter ones like outlined on the cult website.
--Will the sub play low enough for HT if I can equalize it with the BFD?
--Is the sonotube construction ok in a small sealed configuration? Most of the sonotubes I've seen are big ported designs. I like the idea of a sonotube because of ease of assembly and it'll be pretty cheap to build.
--I don't know how to use any of the modeling software so I'm not sure what kind of response I would get given what I'm currently planning. So if someone would like to model it up for me that'd be great.:B
--Is there another enclosure that I should consider that will meet my needs more than what I'm considering now?
I'm also trying to decide how I'll end up finishing the sonotube. I really like the finish on Andrew Pratt's Tumult sub with the Velveteen fabric but I was also thinking of maybe doing something like a brushed metal look (but maybe that's better tackled in post more specific to finishing).
So let me have it. :wink: :B
