[QUOTE="John Roberts, post: 82591, member: 126"] Re: Fun with Damping Factor I am too lazy to do the math. For speakers bolted to a hockey arena ceiling, damping factor is probably pretty low on the list of (audible) concerns. Ignoring damping, the next concern is wire losses vs, cost of copper for heavier gauge. Common practice is to push up voltage to reduce current. Series wiring of multiple speakers could be a service nightmare as one open would impact others in a loop. Perhaps a quick calculation of using 70v/100v distribution. (Cheaper wire, vs added transformers). I like powered speakers, and have heard about them being bolted to ceilings, while this means distribution of both power and signal that could be more expensive, unless power is already there.
