It seems there is still confusion concerning the LFE+Main feature. The LFE+Main feature was never, and still is not, a two way street and while lower frequencies from speakers set to Large are copied to the SUB Pre Out, LFE is not sent to Large speakers. LFE in older units was sent to speakers set to Large only when a sub was NOT present and the Subwoofer presence setting was set to None.
To send LFE to speakers other than a subwoofer connected to the Sub Pre Out, one must use the new LFE Distribution LPF setting in some new Denon/Marantz units when the Subwoofer setting is set to Use and not set to None and other speakers are set to Large. This is the feature
@gene pushed to get on Denon/Marantz models.
For those using the LFE+Main feature on the new AV 10 and AV 20 models, there are no less than three places to make the setting as the IMAX and 2CH Playback settings also have their own LFE+Main settings. The Bass Extraction LPF setting can be found under the Main Speaker settings and also in the 2CH Playback settings which allows for adjustment of the level at which low frequencies are copied to the Subwoofer when Fronts are set to Large and the LFE+Main setting is used.
