A:AnswerThese are speakers only. You must WIRE them to your sound system. These are NOT amplified and require you to already have a sound system. A standard DVD, Blue ray, or projector will not power these speakers.
A:AnswerI have mine mounted 10 foot off the ground and you can hear the tweets perfectly clear. Don't sweat it with worrying about the tweeters, they sound great and aren't designed to be directional to the point that placement is that critical.
A:AnswerYes you can or they have a hole under the screw terminals where a bare wire can slide through and you can tighten the screw down on it for a secure connection.
A:AnswerProbably not, these kits are complete and usually offer no replacement separate parts. However, you could find some metal brackets at Home Depot that you could make work I am sure. Take the speaker with you to Home Depot and just find something that will work.
A:AnswerThey will pivot up but may not pivot as far as you would like. I wanted to direct mine out more but was restricted but the mounting. You could alter the mounting brackets with a thick washer possibly.
A:AnswerThe connectors on the speakers are bare wire posts that finger tighten. If you provide the wires with a iPod compatible connector they could work.
