steelie Posted October 7, 2004 Share Posted October 7, 2004 I was scanning a magazine recently and saw a sub cable that seems to have a pigtail so that it can be connected to both sub inputs. I've always just connected to one sub input and seemed to have success. So, I'm sure this is old hat for most but what's suppposed to be the benefit of doing this. The signal from the output is still the same and the sub has its own amp so ... ? Just curious if anyone knew. Thanks for the help. Quote Link to comment Share on other sites More sharing options...
gcoker Posted October 7, 2004 Share Posted October 7, 2004 The three common ways of connecting a sub is either to the single LFE or to the left or right input or to both. Using the LFE input (if your sub has one) by-passes the subs internal cross-over and utilizes the receivers bass management. Some manufactures state a sight db gain by connecting to both left and right inputs. Quote Link to comment Share on other sites More sharing options...

The subwoofer doesn't gain total output capacity, nor will it sound better. OTH this can be usefull if you have a level incompatibility between the sub and the LFE output... where you are obligated to maximize both the LFE and sub level. Note that many components suffer slightly higher distortion at maximum gain. This will give you 3db extra of adjustability. Rob Quote Link to comment Share on other sites More sharing options...
sivadselim Posted October 7, 2004 Share Posted October 7, 2004 it can SOMETIMES be a remedy when a sub has a problem "waking-up" in auto-on mode. if you have no real reason to use a Y, don't. Quote Link to comment Share on other sites More sharing options...
steelie Posted October 8, 2004 Author Share Posted October 8, 2004 Thanks for the input. I have a huge room but the PB2+ seems to fill it well. No volume issues here. Still, all this talk about the Ultra is making me kinda jelous. I wonder how the automatic EQ on the Ultra would react if it was coupled with a second sub that isn't being EQ'd? EDIT: Is it automatic or are the EQ controls simply on the back? Quote Link to comment Share on other sites More sharing options...
