is there any ways to make your sub have a flatter response from say like 25 to 70hz. Im gonna get two sa 8 v.2s and im wondering if im gonna need a big box to accomplish that or not, some guy said he needed like 5 cubes for 2 of them to sound really good after lots of tuning

5 cubes for 2 8's? That's huge

a bandpass design with give you a flat response but they are hard to design IMO... but you could have ram designs design one for you...

download win isd and play around with box sizes and tuning to get a flatter response, its what i did for my dayton ho's, got it pretty flattened out

win isd does not figure in cabin gain, so you can model up a perfectly flat box, then throw it in a car with janky cabin gain and get no where near the flat response that you were looking for. Some subs just aren't designed to play flat to begin with.

I usually would support this claim but I recently found a feature in winisd that lets you help simulate cabin gain. If you goto the EQ/Filters tab in WinISD and goto add new Linkwitz Transform you can enter in some numbers to begin to play around with your peaks. Set the Q values to 0.707, set the f0 value to about where your cabin peaks. Not entirely sure what the fp value is, I think it's like your low end roll off or something -- just set it to 10hz. I'm still playing around with it

Hmm mine doesn't have that tab. I have version .44 (beta)

how do you find where your cabin peaks at?

Well there are 2 peaks there is one for the meter and one that we perceive. Grab some test tones and play around until you find the loudest one, it's usually between 40-50hz with the peak being closer to 50hz. Mine peaks at around 47hz

Grab 0.50. I think it's winisd pro alpha
