I think I've been over worrying. Found a sound level calculator and it says they should be able to get to 99 db at 12 feet with 100 watts. It also has the same 86 db at 1 meter as the Mofi and both are 6 ohm. I'm sure that speaker can get loud enough. I think that seals the deal for me.That's pretty modest if it's a C weighting. I think the bmr towers will be fine with adequate amplification.
