after you add CD Compensation it will.be more like 98 dB. BTW it works great withthe Celestion 15" Pro wooferthat PE has on buyout.

It gets jaggly down low because the software has to allow reflections in at lower frequencies to get anything. you can't measure a 250hz response without looking for at least 1/250 of a second (the period of 1cycle)... and really about...

I guess a lot of noise has been inspired by interpretations of my rough-looking, in-box, in-room plot of a SEOS12 during design of the 'Designer 10' speaker: Not as nice as something that's a little smoother-looking such as this...

For the record, Geddes also pays little attention to acoustic loading, even as far as saying it is irrelevant. This is hifi, not PA work - getting every last bit of sensitivity with mega power handling isn't a priority. Directivity is,...

You have to watch out, not just for the low crossover point as tuxedocivic points out, but also some of the SEOS designs have relatively gentle crossover slopes. If the designer mentions how smooth or linear the phase response is,...

One way to do the grille is to cut some thin masonite , add holes where drivers are, mount some neo magnets (Parts Express has some sets made for this) in the corners, glued inside small corners. Stretch cloth across the board, wrap over...

A way to avoid errors is to take the schematic and put a letter on each point where a component connects to another. All grounds are "A", all connections that are on the same wire get the same letter (B,C,etc)- including drivers and...

Quote:Will the current Big Mal x over still work with these or will a new one be necessary? I would like to build a Big Mal with these. I'm pretty sure a different crossover will be needed. The plan is that Erich's going to put the...

zThe "direct" sound should follow the 6dB per double distance law, after you get a few feet from the baffle. Reflections will change things though. My measurements were made outdoors largely reflection-free. HopefulFred, I don't think...
