MTH-30 with Eminence Kappalite 3012LF?

@Josh. If you have the BP102-4 try the Billfitzmaurice.com page. he has a couple of designs for that driver.

Hi mate, thanks, I've already been looking at the T39 (Bought Plans) and the Tuba, undecided at the moment though lol

Both are great boxes. I am an authorized builder and have built both. Just keep in mind that you can only get so much out of a 10" driver. Don't expect to have monsterous bass. That driver can handle about 200 watts. I would recommend the T39.

Thanks nate, would you reccomend building 2 dual loaded? or 4 20" T39s?

It all depends on how wide you would want to build your dual loaded boxes. Keep in mind that an average door openning it 30" wide. I would do 4 20" boxes personally. The output of 4 20" boxes would be equal to 2 40" boxes but moving around 40" wide boxes isn't fun. So go with the 4 20" wide boxes.

can i use Beyma 12LX60 in this Cab ?

Or Selenium 12WS600

Or a cheap woofer from Paudio ,E12-250N

Wich one is better ? Cubo 12 or MTH30 ? The drivers that i'm atempting to use are those ones above. I already have 4 piece E12-250n, but if they are pretty bad in this bin, i will buy either the Selenium WS600, either the Beyma LX60 or 12P1000nd.
