i am thinking of building a custom subwoofer using a mmats pro audio 12" subwoofer. It is called the procast or p3.0...

It is dual 4 ohm voice coil. I am trying to sell them but not having any luck so i was thinking of building boxes for them.

i Don't know what i should use for amplifiers... Any suggestions would be great. 500watts and up can be handled by these beasts.. here are the specs.. If i sell these i'm looking at a sunfire sub or a klipsch rw-12d

P3.0 12

Voice Coil (Ohms) 2 x 4
Fs (Hz.) 26
Vas (Liters) 84.0
Qts . .18
SPL (1W/1M) 92db
Power (Wrms) 750

Hello,
Though I did not check your Link, I am guessing it is here where the best discussion pertaining to DIY Subwoofers lies.
Cheers,

Is this for home theater?

You'll need to find out what the Xmax is for this sub, without it only assumptions can be made when trying to model it. Try contacting the manufacturer, maybe you can get the expanded T/S parameters for this sub. From the parameters given it models to 2.5 cu.ft tuned to 21 hz. Xmax will determine the required power input and hi-pass filter as well as the SPL capabilities.

thanks. i already sent out a email to him for specs and to see about reconing them to a single 4ohm vc

When I first saw the "professional" audio when I did a search I thought this was pro audio drivers as in PA applications. I now realize this is car audio drivers. It'll be easier to figure out the modeling since car audio will have more Xmax then pro audio.

Since there are D2 4 ohm, both can be wired together for a 4 ohm load.

From your first post I assume you have a pair of these subs. Did you want 2 separate enclosures or one enclosure with both drivers?

i want seperate enclosures... I am just not sure what to get for amplifiers.. i might send them out to get single vioce coils put in.. Depends on what i need for amps...
