This presents one of the challenges. 40 hz may be more realistic, as I believe the plate amplifier on the Direct Servo has a variable 35-150hz crossover. When I order the system I can specify either a 12db or 24db slope. I'm not sure which will be best.

I plan on building the two 10's and see how they do and what their curves look like in the room before ordering the 15" DS. Brian Ding (of Rytmik Audio), while not loquacious, is knowledgable and helpful.
