    Well im not shure if i spelt that right but anywaayz, i am installing a ib and right now i have an old pair of 12's im putting in with 80wrms each. I am making the box big enough so i can make holes for 15's later. I was wondering if it matters what side of the room its on? would it be best to be between my mains or more twardss one side? it would be more convinient to have it right behind my left main also the cube would have eaquall sides for2 more 15's after i get the other ones in case there not enough. But if i put it in the middle i can only have 2 15's because the studs are only 13" apart dont aske me why but can someone tell me what the best position would be and if i put it to the side will it make more bass on that side?

    If you had access to a normal box sub, you could probably move it around the room near the potential IB locations to give you a rough idea.

    You don't need to make a cube to add extra drivers. You can make a rectangle.

    Look at Kevin U's design, he's got two drivers on each side. Just turn it upright and mount it between the studs.

    Location is best tested by putting an existing sub in the listening position. Then going to the spot where you want to locate the IB and listen to the quality of the bass. If it sounds good, then a IB located there will work fine

    That's sort of dependent on the amount of room gain you get. A rough idea of the output minus room gain, can be created using a box modeling program, with a very very large sealed box model

    I have 2 Daytom IB 15"ers and the PE 250 watt plate amp in a 18'x26' roon and was easily getting 100db's at 18hz at the listening position. If that is not enough then you are probably younger than me. [​IMG]
