1500FE usable freq range?

[baldrick]

Anyone used the 1500FE? If so, how high can i cross them?

Hi baldric,

If You look at:
http://www.audioheritage.org/vbulletin/showthread.php?33555-1501fe&p=339111&viewfull=1#post339111
it can be realized that the driver FR is almost flat over 1kHz, but looking at the THD levels it can be seen that over 500Hz THD raised rapidly,
but if looking at the off-axis dispersion curves again something about 500Hz a kind of beaming start to form (what can be expected due to the diaphragm size). So all in all I think 500 ~ 700 Hz would be the upper usable frequencies.

Thanx! My original plan was to use 1500FE with 2451BE/Seos24 @ aprox 600hz, but the thought of getting M2 waveguide and D2 driver instead have occured, and if so I need to use them up to aprox 800hz. Haven't got the 1500FE yet but hopefully they will arrive in a few days.

I studied the systems and crossovers looking at the different ways to utilize the 1501.

RonThe 4365 is the system to look at with respect to using the 1501FE successfully. Greg did a really nice job with the volume/tuning on that system.
