Good question. The TST3 about the same price as the P362 (list). However, it has more drivers than the P362. The TST3 claims to go all the way down to 20Hz. So they are trying to compete with the Polk RTi12 and RTiA9? That would actually be 1/3 of the price rather than just half.
Needs more cabinet bracing? Sounds like the P362 all right!
8 Ohms and 95dB sensitivity? There's amps to spare with this one. A cheap Sony, Kenwood or Aiwa receiver can drive these things. Dual binding posts for bi-wiring/bi-amping? Yeah, that's similar to the RTi12. However, that backfiring port means there will be no corner placement for cheap bass reinforcement. I hope someone (calling Audioholics staff) will measure this puppy. Those numbers on the
specs page look just wow.
