I have a Carver Amazing loudspeaker. The planar tweeters are going bad. I wish to refurbish (at reasonable cost) the speakers and donate them to the Montgomery College Planetarium which needs a decent sound system. I am thinking of the following for refurbishment. Replace each planar tweeter with an vertical array of 10 Fountek FR58EX 2" Neodymium Full Range Speaker Drivers -
http://www.parts-express.com/fountek-fr ... r--296-725Bi-amplify the midrange/tweeter array and original Carver woofer section using a miniDSP 2x4 so room correction can be applied. The crossover would still be at 150Hz. The question is, is there a problem because the Carver woofers are dipoles and the new tweeter array would be a sealed box. What speaker design tools are you guys using these days. Show me the appropriate software and I could simulate the midrange/tweeter array in both sealed box and dipole configuration to see if the excursion gets to be too big and what sort of spl could be produced.
In general at low crossover frequencies does it matter if one speaker is a dipole and the other speaker a monopole.
