Added a second sub DIY style

[bmccord]

Well, I ordered a dayton titanic 10" and daydont 804 plate amp (240ish watts) and was going to build a new box for it when I remembered I have a nice box in the basement with a blown sub in it....BANDPASS....haha. Anyway, the box is a 6th order, I think, dual ported enclosure. The main champer is 1.25 cu. ft. with a 2" dia port that is 8" deep and the cone side chamber is .66 cu. ft. and has a 4" port that is 4.5" deep. I build the box about 8 years ago and used it as a "really low bass" filler sub. Well, I stuck the dayton in it, and just externally wired my plate amp (temp.) and fired her up....I am tempted to leave it in there. I absolutely blows my yamaha 10 out of the water, it hits REALLLY low for just a 10. Its freq range sucks, most likely about 20-35 sweetspot but it is right where my yamaha lays over and dies. The only thing that sucks is that the ports are just black un flared pvc pipe and below 30Hz at moderate to loud levels, it port huffs like nobodys business....the kind you can feel 10 feet away, so, i just faced it into the corner and played with all the settings and I am very satisfied with it. 9 out of 10 times, the overall sound level masks all port huffing but in the into of the "Fifth Element" intro, its nearly all really low bass so it sounds a little odd, however I have found a solution. Turn it up even louder and you can't hear the huffing over the walls shaking ...hehe.

That box is a terrible match for that driver. You really might want to think about another box. If you add an additional 2" port and cut them both to ~7" it should get rid of the port noise.

no kidding, that Box is a POS in general, however I was just curious to see what it sounded like in it because I have yet to build a box for it. I am almost considering a sealed box. Basically I want max SPL in the 20-60Hz range so who knows. I was only posting to say that it hits really hard down low where my cheap Yami can't get to. Oh yeah, note to mod, don't delete this post now because this seems people are responding to this one

I think you are going to have a hard time designing an enclosure for that woofer that gives you that type of response. I looked at that unit for one of my subs and never could get the code to look like anything I wanted. It is designed for a smallish sealed enclosure, and to use an eq to compensate for the roll off of the box.

I hear what you are saying. I was sort of crossing projects, for that SPL and loudness was going to be a couple of 12's, however I am just using this sub in an old box in a different room, not my main theater area, although its in there now just for giggles...I still can't decide if I want to do a single 15" or a dual 12" for that deep loud earth shaking bass, yet still have nice tight punch for music. Thinking a sealed 15" may be the way to go...who knows
