SVS SUB BETTER WITH LOW PASS FILTER OFF

The only heresy I know is trying to do this all without measurements first.  I mean, it's dogma, but I find getting this right by ear alone is so random. 

Bloom and bloat IMHO had more to do with room modes, where a little EQ can go a long long way.

Glad you found a setting that works for you.

If you play just your subs you will probably hear male vocals in your subs this way. If it sounds fine… no big deal. The slope at your amps 80hz might not blend well with your mains. Maybe try a different slope if possible. If the slope is 12db for example it is out of phase and you would need to make the sub 180 degrees or change the leads on the speakers. Could just be nulls and room nodes 

Super good tip! My mains are Klipsch Lascala (II) so the bass is weak. The amazing thing is that the music sounds so much more "organic" (if you can imagine what I mean by that). Cohesive may be an even more unhelpful word but whatever...I like it better. My room too is unique in that I live in a yurt which fails to provide any reflective hard surfaces. (All fabric) So the normal rules don't apply.. I'm afraid I'm on my own on this one. But...it sounds amazing...just sayin'

I’m not 100% sure but it sounds like you might have been double ganging the filtering. You say your subwoofer output from your preamp or amp is 80 dbs, I think you might have meant 80Hz. If so, in most cases you would NOT need the low pass filter set at all on the SVS subwoofer itself then. The correct thing to do in this case is to either bypass it entirely (which you have found sounds better) or to turn the setting on the subwoofer as high as it would go, say 250 Hz or whatever, such that the slope of the crossover in the sub doesn’t interact with whatever slope is used by your preamp when it does its low pass at 80Hz. Anyway, that is what my old Klipsch subwoofer manual says to do. In other words, you’d only engage the sub’s crossover and low pass filtering if you were sending it a FULL range signal from your preamp. So, I’m just guessing here, but what you were hearing before might have been the crossover slopes of the preamp or amp subwoofer output interacting with the slope of the crossover in the sub. Removing the one from the sub filled in that "hole" you were describing, so it now blends better with your main left and right speakers.

Yes, of course 80 hz was my intention, and as usual for me its the most obvious stuff I miss. Glad I randomly discovered my mistake. Sure is much better. Now to put more Nano goop on my contacts! Any obvious advice on this sub I might have missed as well?
