Re: [help] sub driver recommend

If you mean outperform I would say yes.

Each PR's will need 550 grams of mass added to tune the box to 21 hz.

Re: [help] sub driver recommend

You want the dual 2 ohm subs, each sub is wired in series for a 4 ohm load, one sub connects to each channel of the amp.

Re: [help] sub driver recommend

The link won''t show your calculations, you'll have to post a screen shot.

Here is the cut sheet for the 24" cube design. This was originally for a SDX15 sub, your cutout diameters will have to be for the A.E. sub and Exodus PR's.

Re: [help] sub driver recommend

Shackster, also consider the AE AV15X driver. In a box of 6.5-7.0cf with PR's, it might be a better option than the AV15H driver which does very well in smaller enclosures. The H driver is a bit better for the low bass and the X model a bit better for the mid-bass. I'm using the X model in a 7cf box with 18" PR's and it has impressive performance. I also believe this sub with either the X or H driver in a 6-7cf PR box with some 1,000watts of power behind it will beat the Ultra 13 with no problem for the mid-bass (50hz-100hz). The low bass performance (below 30hz or so) should be very close between the two.

Probably not. Build the sub and see how it sounds first.
