you must be getting some good sound - I don't think a graph tells all the sonic story of a woofer's performance - Eminence's graph shows some rolloff but your Kilomax must be doing ok in the xover region or you wouldn't be so darn happy. I wish Eminence would detail conditions and give off axis data.

btw-I have a Behringer xover but had ground loop problems - will have to sort those out.

I need to locate some of the 1" Russian plywood - hope 84 lumber can order - you got it for only $30/sheet!! - I'd be happy @$50-60 for 5x5 - I'd be in 'box heaven' with 4-6 sheets!

Best wishes!
