Do you adjust your subwoofer

A bit more info, the remote app for my SVS subs is very useful.  Adjust from your fave seat and enjoy.  Can't say enough vs getting up and twiddling knobs in a darkened room.  Glad to see that not everyone buys into set and forget, it was what the engineer intended.  

I’ve got a Rel s510 and once it’s dialed it pretty much stays that way across the board. Possibly a tweak here or there, but rare.

Often.     My subs came with a remote that controls all the subs Optimization parameters and its six customizable presets.. 

Slight volume adjustment are used mostly. Possibly one or two presets which embellish some aspects of the recordings low frequency to my taste which lie below the established crossover region (100Hz - 33Hz).

I'd like to second @mijostyn clarity regarding -6dB sub-bass products. Don't you just love it when someone does the math? Nice.           

"@akgwhiz Glad to see that not everyone buys into set and forget it" Me too! It's literally the most fun we have with our system. My preset for Rap KILL'S it.

My 2 RELs crossovers are adjusted at the point where the main speakers drop off, with the sub levels and phase checked once in a while. I have a Schiit Loki Max EQ and use that in there a little bit if a recording needs it. 

I’ve two REL Carbon Special and occasionally I’ll bump the volume up a notch when I pull the screen down and watch a concert DVD. It’s a bit of a nuisance with the RELs as the gain knob isn’t marked with positions and I can’t feel the notches which are supposedly there. Also, a couple degrees of adjustment results in too much or too little volume. Fantastic sounding subs but ergonomics could be so much better. LEDs on the sub with remote volume would be bliss!
