I would not agree that 15's and 12's are both the same. From your background in DIY, you know that beaming and cone breakup modes occur at the usual crossover point of a 15" two way system. Also the crossover point can be higher on a 12, so the horn does not distort when pushed at low frequencies, and the resonance peak is more easily hidden (unless it's ferro fluid cooled). In my opinion, it takes a better designed 15" 2-way to sound as good as a 12" 2-way in the range you intend to use it. 12's are more portable too. Others may correct me if I'm in error. |

The room is a large lecture hall, with balcony seating, and a total capacity of over 400. So I want to know, what top boxes should we be considering with a budget of $1200, or $600/side. I spun this thread off from the single-18" subwoofers thread, because we are no longer looking for subwoofers, but mains. |

The noise about "beaming" at "usual crossover points" is confusing. And, no horn should be pushed "low" - that is simply wrong application. I don't get the impression portability is an issue... Budget, is, and that might preclude some othewise great choices. To refute the crossover noise (above), both these have internal passive xovers at 1,800Hz (and could be bi-amped if you choose). |

I sent two emails to you, but maybe I didn't have the right address (?). Did you get them? Dave |
