![]() ![]() If you are settled on a 10 cubic foot box then I would try and do an 18 hz tune and bump up the port size to at least 6" diameter circle port. Please let me know if you think those are off or if they are even good for a budget diy sub. I'm not sure how accurate WinIsd is but I could definitely live with those figures. 15hz is at 101db, 13hz is 96.8db, 12hz is 94 db with 10hz all the way down to 87.9db. Using winisd in the 10^3 box (11.6 cubic foot are bigger but that is just too big) with either a 4" x 8.2" circle port or a 4 x 4 x 11.25" square port the figures are: 100w/1m no room gain 107db even from 500 to 30hz with an f3 of 17.4 hz. I want a good clean 500 not a cheap 2000.Anyway, let me run these number by you, i'm kind of intermediate in subwoofer knowledge but the figures seem really good so let me know what you think. Don't want a behringer though, I only want around 500 watts and the Behringer's are all like 2000. Looks like having a 10^3 enclosure built will be about 200 and I'm expecting the amp to be around 150-200. Thanks brandon, I've had the Dayton 15" HF for almost 2 years just sitting around so that is absolutely what i'm using. My question is would it sound the same as the recomended enclosure or did it give me the odd numbers for a reason? I've never built a sub box and i'm wondering would 3/4" mdf do the job? Would I have to brace a big ported enclosure like this? I ran the figures with a sealed box and although it would be considerably smaller it seems i'd lose a good deal of very low bass for movies and some output. Those are very odd numbers, I've found that an enclosure with dimensions of 28.5 x 28.5 x 28.5 would have the internal volume of just. The outside dimensions of the enclosure it recomends are: 28.85 x 45.26 x 17.91. So i've entered the sub's specifications into winisd and it's telling me that with a 11.365 cubic foot ported enclosure it would be flat from 1000 hertz down to 20 hertz.Down 1db at 19, 2.5db at 17, down 3.5 at 16, down 5db at 15 and down 10db at 13 hertz.Those seem like very good numbers and I'm sure i've entered everything correctly. ![]()
