Asa,
The LM755 field coil speaker with your Air Tight 300b amplifier would seem to be a potentially superb combination.
I woulnt rule out Border Patrol. Exceptional build, styling and sound. I am a manufacturer myself and still would recommend putting Border Patrol on your list of considerations.
I know the amps mentioned here are top dollar...but I think the Cary 300b SE monos are fabulous for the money.
