Raising the While Flag on 604 Project

vuki :

I tried your hi pass XO section with my 605s , and it sounds great . What did you use for the coils ?

Todd:
Thank you for the Vocal Master plug . Limited BW, yes ," VOCAL " , everyone else has an amp and speakers. BTW to sound right they must be driven by a Shure : VA300, VA302 or PM300 , all of wich are current amplifiers. YES one VOLT in produces one AMP out. This makes the AMP into a equalizer, the output voltage follows the column impedance curve.

Nice to hear you like it - probably it works on 605 too, but it is designed for mantaray type horn- IIRC 605 has old, multicell type horn? It could be that the responses are similar enough. I used aircore inductors. Since both inductors on highpass filter are in series with relatively high valued resistors, Rdc of inductor isn't important -the cheaper the better

Hey Don,

Yeah, we used to call them the "VocalBlaster" - and the speakers "Sound Collyum's"...

Really quite inventive, though, wouldn't you say?
