The reason I asked is I dont know why id want the crossover engaged if I am using lfe+main, or if that setting ignores the crossover setting... and there are multiple crossover screens as I recall. There is one screen that shows all of the speakers and their respective crossovers.
Right, there are a couple of relevant screens, I just browsed the manual and this is how it works:
1. The "Bass Setting" screen (under Manual Setup > Speaker Setup) is where you set LFE/LFE+MAIN and also the LFE LPF (which only affects .1 LFE material, it isn't a crossover).
2. the "Crossover Freq." screen (also in Speaker Setup) is where you set the actual bass management. If you look on pg 26 of the manual, it says that if "LFE" is selected for "Bass Setting" then only speakers set to "small" appear and allow a crossover.
But (here is the confusion) if you are set to "LFE+MAIN" then you will also see crossovers for speakers set to "large". So I was partially wrong -- that "crossover" will be the LPF for the "double bass" on speakers set to large.
So, if it is set to "LFE+MAIN":
- if a speaker is set to "small" then the crossover operates normally, e.g. set it at 80Hz and it reroutes everything below that to the sub
- if a speaker is set to "large" then the "crossover" becomes the upper limit for the double bass also sent to the sub, e.g. if it is set at 80Hz, the speaker will play full-range and the sub will get "double bass" below 80Hz.
I need to find that screen for 2.1 settings and adjust that because the gap between music and games/movies is more like an impassible ravine when it comes to bass.
Also in checking the manual, I discovered that the 590/1610 does not have this menu (it's a dedicated 2CH DIRECT/STEREO menu where you can set different bass management for stereo mode). I guess that functionality is a "step up" feature of the 1910/790.
So, if you have set your fronts as LARGE and LFE+MAIN then when in STEREO mode you will get 2.1 with "double bass", e.g. both fronts playing full range and the sub also playing everything below the "crossover" freq.
The good news though is that speaker volume settings are memorized by SURROUND MODE, so you can have a different SW channel level in STEREO mode versus multichannel modes.
What I would do is re-run Audyssey (if you haven't already) and get everything tweaked to perfection for movie content (again, because this is a known REFERENCE that we can peg to). Dial the knob in on the subwoofer before re-running so that you end up with a Channel Level for the SW that is somewhat negative (e.g. -5dB), that will give you a lot of room for upward adjustment with music.
Then, post Audyssey, once everything is dialed in for movies, we can work on getting music content to sound right. Are you listening to music with Dynamic EQ on? And Dynamic Volume off? Do you find that the source level is way off, e.g. when you switch from a movie to music the volume is either super low and you have to crank it up, or it is super loud and blows you out of the room?
This may seem like a dumb question, but if I did want to add a second sub, would I just need an rca-y splitter? There is only 1 subwoofer preout.
correct, you would just need a simple RCA y-splitter.
