OK, so I know, but I still have questions. These are huge, oversized
4 Pi's (~7cu ft) with Kappa 15's and PSD2002's on Selenium horns, 10db pad
X-overs. So, these are hooked up to a mixer, CD player, and a Berhinger EP2500.
Without cranking all that loud, the lights on the X-overs are flashing. I mounted them on the back wall beind the ports,
so it lights the ports up. Its kind-a cool.
I'd expect to be able to get a LOT louder before the lights turned on. Any clues about what might be happening?
I'm reasonably sure things are wired correctly.

BTW, they sound really nice. These were made to be PA speakers so the finish is truck bed liner (Hurculiner),
so the WAF is pretty low. My wife is a good sport, so as long as I make up some grills
I get to leave them in the "music room" in the house.
I'll post pictures when I can get some decent ones.

Thx, Chris

I always like seeing the insides light up too.

You might check your tweeter cable assembly, if you think the light is glowing prematurely. If you have the wrong resistance values, that might be the cause. I guess it couldn't hurt to check the other components in the tweeter circuit too.

Then again, you might be just cranking it.

As for the R values, don't these make the impeadance around the
X-over freq about 24 ohms and decreasing to 4 (in my case) as
freq. rises? What I'm worried about is that the X-over is
spec'ed at 1.6KHz at 8 ohms. Does the higher impedance at
the lower end skew the actual x-over freq? Seems like it would.

Overall sound is still impressive. Didn't try any other
CD's, but hooked up the Korg organ. Sounds really nice.

Thx, Chris

If resistance is too high, the circuit will be underdamped too much. It might even be so much that resonance in components L1 and C2 might drop circuit impedance quite low around 2.3kHz. That would increase current flow in the tweeter circuit and may cause the protection bulb to light earlier than expected.
