A:AnswerThey can be installed on a drop ceiling as long as there is clearance for the speaker to fit and also the material is strong enough to hold the weight of the speaker. I would place them directly above.
A:AnswerYes but I knock them out when I do installs. They're basically there so the sheetrock or wood installers cut the hole for the speaker durung construction. You also have to make sure the installers cut the inside of the ring and not to the outside of the ring or the speaker will not latch on.
A:AnswerI had to fish wires from amp. Up to ceiling from its wall location to each individual wire. If you have an attic it can be done without cutting drywall
A:AnswerThey are made to clamp to drywall. Depending on your open ceiling style, you could build square box to hold speakers and would help with sound as well. The speakers would clamp to any 1/2 inch or so board.
A:AnswerPair these with any speaker that has a similar wattage sensitivity and frequency response. If that doesn't match, then it will definitely sound weird
