Back on topic about whether the Statements can play at high SPL, probably not by PA standards. But Jim Holtz (co-designer of the Statements) replaced some large ribbon/cone line arrays with the Statements and didn't notice any loss of...

Hey guys, Been away a couple of days. I apologize for being rude to any and all. I think, if you disagree with someone, you should man up and tell him (politely) to his face and explain why you disagree. Starting a thread on another...

Quote: One of the SMPS side heatsinks gets hotter and hotter Hmmm, that could be a problem. The old models, and presumably the new ones, will shut down if the output stages get too hot but they may not have put thermal protection on...

In a perfect world, your speaker would roll off 2nd order Butterworth at 80 Hz. That's Q=.7, -3dB at 80. That adds to the receiver's BW2-80 electrical filter to give an LR4-80 acoustic response (-6dB at 80). I'd consider using a sealed...

FWIW, here is a typical air-core coil you might use in a 1K crossover. .6mH, .15ohm, 800W capacity, no hysteresis, $15. http://www.parts-express.com/pe/psho...number=266-330
