A friend has 4 JBL 2206 professional drivers, and wants to use them to build a sub for his FP theater. Is there any scenario where he can put these to good use, or is there no way these will go low enough? He has a wedge-shaped storage space to one side of his screen area that measures 116" deep x 55" tall x 66" wide (hard to explain -- like 2 right triangles 66" base, 55" tall, approx. 86" hypotenuse, 116" apart.) Any way to use these drivers in this space to produce any decent bass? This is like the blind leading the blind, me trying to advise my friend, so I'm looking for a little help! Thanks!
