Ok, I have a dumb question for people who know about the Audiocontrol crossover modules:

I have an 80 hrtz 16-pin resistor, but I need a 14-pin 80 hrtz resistor. Can I use a 16-pin in a 14-pin slot (with the two extra pins hanging over the edge)? Will it still be an 80 hrtz resistor if I use it at 14 instead of 16-pins.

Ok, that is my main question, but here is another question to discuss...if I have an overlapping crossover frequency between my subs and mids will their typically be cancellation?

overlap is something youve gotta play with. ive got overlap between my midrange and my midbass, helps with blending since my tweet and mid are right next to each other, and the midbass is farther away. midrange plays down to 140 hz, midbass plays up to 200

some call it "the art of making speakers disappear"

Yeah, the overlap I have is actually pretty minor...my sub is low passed at 80 hrtz, and my midbass at 70hrtz. However, my bass is flat from 35-65hrtz and just starts to drop after that (going up). The midbass is funny because it drops a few decibles below 90, but then it is flat from 80-60 hrtz (even with a 70hrtz LPF...go figure

Man, I need to figure out how to incorporate my midbass into my system. I have about 150 watts per side for the comps, and about 600 per sub...but I have 90watts per mid on the kickers that are rated for 125 watts (These are all rated numbers, and JBL amps are usually underrated by a bit). I have the mid gain on the amp half way up, and I had the x-over gain at like 3/4 of the way up (which seems high to me), and the mids started to noticibly distort at my maximum volume that I set...so I backed it off slightly and it matches up with the highs well, but not the bass.

Is it possible to clip an amp so much that it actually puts out less watts, and therefore puts out more distortion? Basically the concept of less is more?

umm i have the 18db/octave 80 Hz chips (14 pin), (hehe im an audiocontrol dealer!) so tell me if you want them

I do, but I can find most of them at Mouser.com for about 49 cents each...I can't justify spending $15 dollars for one

...80hrtz are hard to find though

lol, yeah i know, they've been in the back of the shop for like 2 years.

sir, just make em from mouser parts

I found this on the Audiocontrol site:

Q. Can I change the slope on my crossover with a new module?

A. The crossover slope (18 or 24 dB per octave) is controlled by the crossover design, NOT the module. There is no way to change the slope on our crossovers. If you plug a 24dB crossover module into an 18dB socket, the crossover will work but it will also still be 18dB. On the other hand, if you plug an 18dB module into a 24dB socket, you won't have sound playing out of both channels because it is missing a couple resistors.
