I have twin turbos. I have PMC IB1s for mains. They are a TL design with good response below 40hz (30hz is about the practical limit) and excellent, "tight" bass. Like most of the PMC line, they can play very loud and clean. I have the xover set at 40hz. I may try a slightly higher xover in conjunction with some relocation experiments, but with my current locations, the sub interactions are causing a big null at the seating position at 60hz, the IB1s seem to smooth this out considerably.
