A while back when the W7s were first comming out my friends went to get some trainning at the JL facillity. They told me about this box within a box called a whole box or a hole box... I don't remember. You guys ever heard of this?

I would guess if it was at a jl training tutorial it would not be a waste, and I would bet they were refering to the design similar to thier high output boxes. I have built a few of these sucessfully, but no where near the SQ that they get out of them.

COuld be a high efficiency resonance chamber tuned to vibrate(not audibly) between a certain frequency range.

If that's the case, these were used back in the day. People put them under their home theater floor and coupled a few 18s/24s to it. Just think, 110+dB at 15hZ Hole Box or Whole Box? -- posted image.

It is the JL Audio H.O. box, and it is just there high output bandpass boxes, designed for SPL.

You guys might be right. They must have called it a HO box. You guys know where I can get more info on this?
