Re: Interesting discovery - receiver "modes"


It became even clearer when I had speakers set to small, XO at 80Hz, switched off the sub and ran a sweep via Direct (even though the XO was at 80Hz) and then a series of XO via the Stereo.

Graph shows for MAINS only:
Direct
40Hz XO
60Hz XO
80Hz XO
100Hz XO

Interesting that with room gain my mains are producing more or less target level output (75db) at less than 30Hz on a crossover of 60Hz. But there is quite a dip in the all importnat 40Hz region!
