Joe, no redirection of the bass from the mains to the sub occurs in general in that situation. Most receivers have a setting(LFE+Mains, Both...which would duplicate the lowest bass from the mains to the sub...


OK, understood and thanks.

This raises several issues:

(1) In a 5.1 combination HT/music system, why would you EVER want mains=large? It works OK for DD 5.1 material, but every time you play a stereo CD, your subwoofer is totally bypassed.

"Larger" speakers like the M80 have good bass but not equal to an EP500/EP600.

Newer stereo CDs (say within the past 15 years) often have a lot of material below 80 Hz. If you have a robust subwoofer, having mains=large leaves it silent for stereo material.

(2) LFE+mains/both seems a possible solution, but you have the "bass doubling" problem. Also, when switching back to DD 5.1 sources, wouldn't the bass doubling problem get worse?

(3) Most popular "help" articles I've seen don't clearly explain the difference between bass management of 5.1 sources vs stereo sources and how mains=large vs mains=small affects this. IOW they typically explain mains=large vs. small for 5.1 material, but omit the different consequences of stereo material.

Any further comments?
