We have a local sub builder here in Colorado named James Pantazes who built some 15's using the 3" coil version. JP posted a video of them on his youtube channel
I appreciate the suggestion. I did see the ebay ad earlier this week, but at 258 each shipped I think I rather buy something else that's new. I'm interested in buying some, but not over what they sold for new.
$311 for a M3000.1D is a superb deal. I wish I would have seen that. A 3k mmats amp usually doesn't go that cheap. What attracts you to these amps? Is it their efficiency?
