PE# 260-160

Has the same 12db low pass & 18db high pass characteristics as the Eminence pxb with a built in L-Pad for the tweeter attenuation. I'd be inclined to replace the cheap pot with a fixed resistor once it was dialed in but might be a nice all in one solution.

Any comments Wayne?

Notice, Dayton uses air core inductors, didn't eminence use those little iron core ones?

Seems like a good product.

Still have to add the high freq compensation and replace the POT with a fixed resistor.

Response curve of the crossover's tweeter circuit

The response curve shown above is characteristic of the tweeter circuit in all π Speakers using a compression horn tweeter in a two-way configuration.

Using the values shown on the crossover chart distributed with each of the crossover schematics, midrange attenuation values of 6dB to 21dB are given. In each case, the response from the crossover frequency up for the first couple octaves is flat, with 6dB/octave augmentation above that. This response curve is required to compensate for the tweeter. So the moral of the story is that the R1/R2/C1 compensation components are carefully chosen to provide a curve that exactly conjugates the compression driver's power response.

That's why I suggest that L-Pad's not be used, and that the values shown on the crossover document be used instead.

Any thoughts on using an active crossover with 4th order slopes?
