    Flat response

    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

    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...

    Re: Flat response

    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)

    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
