He was IB with the Maxes...and it doesn't take a ton of power to get the Maxes to reach full excursion IB. 300 watts to a Max IB and she will pretty much max out excursion.

On paper there are things about the AE sub that would make it more attractive for IB usage.

Then there is the weight savings.

Andy, go by Joey's and get him to show you the sub I brought up there today. Very impressive build for the price point.
