Triticum Agricolam Posted May 14, 2016 Report Posted May 14, 2016 Nice job with SketchUp? How much power are you going to be running? Your port area might be a bit on the low side.

Clownrock95 Posted May 14, 2016 Author Report Posted May 14, 2016 Nice job with SketchUp? How much power are you going to be running? Your port area might be a bit on the low side. About 1200 watts at 1 ohm Something I should have added is I as worried about the back of the ports being to close to the back of the box is 4" enough??
Triticum Agricolam Posted May 14, 2016 Report Posted May 14, 2016 No a single 4" port won't be enough, you would need two 4" ports at a minimum or a 30 sq in slot port.

I meant the space behind the tubes they are 11" long and the box is 15" deep so that leaves 4" behind the port (actually 3 1/4") I wasn't sure if that would be enough

So I'm just barely in the clear there
