Looking at a set of these to try in my A pillars. I wanted to go with a coax and something that was bi-ampable. Does anyone remember what the sq on these was like? Also possible xover points if run active? By memory, I think the passive that came with these was around 3k or a tad lower for the tweeter. Does that sound about right? The other big question is how low do you think these will play? I would be trying to get down to the 300 range ideally, but could possibly play as high as 500?
