LE15B + 2450SL W/ TrueExtent Be Diaphragm + Compensated network

[CauYem]

Based on data, which Guido & 4313B measured, I built a 2-Way 640Hz Crossover with EQ network to compensated for both Low & Hi to see how the 4" Be diaphragm in a 2450SL driver & LE15B (in Hartsfield box) perform.

The 2450SL/Be is mated with a SAM1HF horn. The crossover measurements were done with HP Network Analyzer & HP Impedance Meter. Here is the result:

SWEEEEEEET! Nice work!:applaud:

I increase the slope at the low end a bit more than 1dB, and here is the new measurement. The sensitivity of the Hartsfield now drops probably to about 93-95dB. Parts used are not the best, but they work fine with the designed network.

Nice. I'd love to hear/try that combination!

How does it sound to you? (I think I already know your answer) ;)
