A:Answer Not sure I understand the question, but I'll try anyway. If you're concerned about assembly, the only thing you have do is place the dust/grill cover on it. If you're talking about speakers, it's 2 8" woofers and a 90° x 90° Tractrix horn. If you're asking about how many of these per box, the answer is one. You'd need to buy 2 for a left and a right.
