Re: Sierra-1's on their side?
if they are going to be on their side, the tweeter should be turned. i seem to recall someone on this forum receiving a "center" sierra with the tweeter positioned like a main, and davef saying that if they felt comfortable, they could go ahead and turn the tweeter themselves. you should definitely contact ascend before doing this, but it doesn't seem like it would be hard at all to accomplish...
