Seen on ebay: http://www.ebay.com/itm/Electro-Voice-U ... Sw03lY58Zx Wondering why the back of the cone is white? It's made of Styrofoam! Roscoe |

This is one thing I clearly don't need to own. So there's one. |

Alnico. And, remember the scale, that's a 30" woofer... Roscoe |

I recall many years ago a shop named The House of Sound had a pair of Electrovoice Patricians on display that was fitted with those 30-inch woofers. Let's just say that the Patricians did not break a sweat from pipe organ left-pedal work. My pockets were not nearly deep enough to buy them. |

I read a vintage white paper that discussed the ALNICO vs. ceramic magnet assemblies issue regarding sound quality. To make a long story short -- the ALNICO magnets completes the magnetic circuit around the voice coil -- the ceramic does not. Why does that matter? It provides damping and puts the "brakes" on the motion somewhat like how the pedals on a piano are used. The speaker follows the signal better and the rise and settling times are more in line with the actual signal. |
