Axiom Home Page Forums General Discussion Advice from Axiom Owners I have more bass punch WITHOUT a sub

Here is what I have found from testing my own AVR-3806:

Large, LFE – Subs do not get Main low frequencies. They may get LFE (not sure)
Large, LFE+Main - Subs do not get Main low frequencies (this is the anomaly – but it is probably programmed this way because Large overrides anything else). The subs may get LFE (not sure)
Small, LFE – Subs get LFE, but not main low frequencies – The main low frequencies go to the mains. LFE is crossed over at AVR LFE Crossover point.
Small, LFE+Main Subs get LFE and Main low frequencies – Crossover is at AVR Main Speaker Crossover point.

Whether or not the manual states otherwise, several sources have confirmed that when set to Large, the subs do not get the main low frequencies. Granted, this is on older Denon AVRs (06 and before). The 08 series may have fixed this.
