    need guidance designing vented box for 2 audiomobile EVO-R's

    I've got 2 audiomobile EVO-R 12's running off a US AMPS exterminator 400x which is pushing out 750x2. Currently I've got them in separate sealed boxes slightly larger than 1 cubic ft. for each.

    I want to build a vented eclosure that both subs will go in. I want to make a box with both subs on the face and the vent one side or the other of the two subs, but on the same faceplate.

    I figure with the space in the trunk I'm working with, I can have a box with internal volume of 5cubic feet max, and can get as small as 3.5 cubic feet. Can anyone help me with port dimensions (rectangle port) and how big or small I should make the volume?. Any help would be much appreciated as tech support from audiomobile in nill cause they went out of business.

    Lucky dog. I would love to have those woofers or a pair of Mass series even. Do you have a sheet for those with the T/S parameters?

    Ya I do. All the specs are metric. Here is a link to where the t/s paramaters are. http://www.adireaudio.com/Files/DUMAX/EVO-R4Adire1.pdf thanks for looking at my post. Any help would be appreciated. I've got between 3.5 and 5 cubic feet total to work with for total volume.

    Well I do remember them working great in very small sealed enclosures. I am not sure about ported.

    ya, they slammed in the small sealed boxes. in an elcamino with that us amps putting 750 watts into each one. Want to try them in a newer vehicle and see if they'll slam harder in a vented box. Just don't know exactly how big to make the port or total volume for the box.

    I owned a pair of Mass 2012's a few years back.

    Wasn't too impressed with their output
