Thank you for the response. Most of my concern is how linear the driver in as you go towards 20 Hz. I currently use a 4 cuft box tuned to 28 Hz. I then electronically eq it to get flat to 20 Hz. The Xmax on my 2241H is about half of these drivers. I have heard and used the 2242H however the cost is steep.
I will post back with my experience with these guys.
