Here's the deal, having a hard time with the sub I have and want to figure what the best box would be for it and I'm waiting SQ with flat response --

Sub - DLS SP12

Specs - http://www.dlsamerica.com/speakers/sp12.htm

and manual - http://www.dlsamerica.com/pdf/manrultsub3.pdf

any opinions?

I would be iffy about choosing that sub. How flat do you need it to be (to what frequency)?

try a 6th order?

I was thinkin about going bandpass...

I just want the sub to be flat up to about 200 hz, not that I'll play it that high, but I want it to mix well with the varied music I play.

I love the sub, the output is great but was boomy in the previous box, but there is no way that it should only have sounded decent up to 50hz on my lpf previously. I need to fix it. I think maybe the box was just too big..... It sounded great sealed but I don't have enough power to run it to its potential in a sealed box and honestly I am starting to fall in love with ported enclosures :)

yeah...i see where your coming from...id rather eq it out then be limited by the enclosure

Yup yup, and the weird thing is above 50hz it sounds SOO bad..has to be the enlcosure.. I need a lil more than that out of it!! :) or at least the ability for that. I know this sub is capable of great things and the FR goes up to 2k.

maybe if you're really creative try to fit a Tline tuned to the subs Fs.

Not sure what that is, I'm pretty new to the world of ported enclosures....

200hz? You don't want or need a sub to play NEARLY that high. I would think it to be easier getting a flat response to a lower frequency.

Well I wouldnt play it that high, I really just want it to be flat up to 100 hz or so, it'll be x'ed at 63 or 80 if I can get smooth response at those freq.'s.

Would a larger than ideal box be more likely to cause boominess or a smaller than ideal box?

Larger usually sounds a bit more boomy...I had my old RE SX15 in 5 cubes as opposed to 3-4. It was tuned to 35hz with 3 aero's and dropped wayy lower than setups I've had before tuned to high 20's.

So I guess I need to go smaller to get away from the boominess :)

Yes, but you will never find an enclosure that will have a flat response from ~20-200Hz...

However, to get the response you want, you should deffinitly try a bandpass of some kind. It will never be as good as you are asking for though.

Looking for more like 20 to 90hz -- smaller ported box perhaps?
