Default Who in here apply EQ to their subs?

And how do you like it? I'm of the impression that many bassheads and HT enthusiast don't apply eq to their subs.

Anyone who cares about sound quality would almost surely use some type of EQ. Rooms/boundaries/walls do strange things to bass, and one of the most effective ways to tame those anomalies is with proper equalization. Bass traps and room treatments are another good method, but electronics is the fastest and easiest way to mitigate most issues.

There are two excellent ways to get your ass whooped: staggering, stone drunk, into a biker bar and shouting, "Who's riding that piece a crap out front?", and depending on electronics to equalize your subs.


Either way, you wind up spitting teeth, and bystanders will tell you - to your face, if you still have one - that it was a serious mistake to even go down that road.


I adjust subs, manually, and I stay out of biker bars altogether. Voice of experience here.

I'll definitely take my chances against phony aggressors and wannabes who allege to have experience. You're free to waste your life fiddling with knobs and dials, but that's a fools errand reserved for those stuck in the stone age. Those of us who want to spend our time enjoying what we bought, and not dicking around with minutia that will has no perceptible value, will laugh as you while away your time in a vain effort to eke out the inaudible last percentage or two.

Be sure to bring your little sister the next time you go to a bar. That way, you'll have some protection.

Hostile, much? I don't have any sisters.


Currently, I have four theaters in my home. All are mixed use, and the living room is the biggest. Four subs - two Fathom F-113 units (one is the more recent Series 2) and two SVS SB-13 units.


There's other gear in there, but of note is the Marantz 8802A, pushed by a Marantz power amp. It's a fairly complex setup, but not too bad.


The real problem is that everything has electronic adjustments for sound. The amp uses Audyssey. JL Audio has one type of parameter setter; SVS another. Which one should run first?


Should the audio environment (sound treatments) be dealt with on an individual basis, per speaker, or in concert somehow? Is fancy equipment like spectrometers necessary, or should it stay rudimentary, and subjective for the knob-twiddler?


It took about half a day to figure out the so-called electronics were overwhelmed by all this stuff. There is more (and less) involved than all these pyrotechnics - it's fine for one sub, dead in the water for four, especially for a basshead like myself. It took another (separate) half day for some basic sound treatments and adjustments, level matching and whatnot.


I started out in radar, moved to computers, and I don't understand why you consider that a wasted life. Of course, everyone is entitled to an opinion, even about the Stone Age. In fact, I'd rather have one of those guys with me in a rough bar, than somebody's little sister, unless it was
Ronae Rouse or Gina Carino or somebody like that.

I think sound treatments like bass traps are included in the eq scenario.

I do any EQing after I've measured with sound treatments. I generally find that I need fewer filters. With MathAudio - its even easier, I measure (about 8-20 measurements), save the sum measurements, put it into the VST in JRiver and adjust my curve. Comes out very nice.

Yeah, but you're some kind of genius, unlike myself. I'm a knob-jockey from way back, unfortunately. Using the built in gear is inadequate, and can result in language that would make a sailor blush.


I've watched the gearheads from MIT and Caltech go from casual beer-drinking to name calling and non-contact fisticuffs more than once, and it scares the crap out of me. Obviously, you have it under control, simply by doing it yourself. I do it by ear, Neanderthal style, but at least it keeps my nerves from jangling like an old-school firehouse bell.


It's rough out here, man.

As do I.

Seeing as I'm using older gear, that's the only option I have. Let me just say, NOT ONCE has anyone ever had anything negative to say; even those with newer equipment costing A LOT more than mine....the only thing they say is wow! I have no problem taking the time and effort to do the best I can, with what I have.

I got the PBK kit when I got my first Paradigm sub. In a review I read somewhere, I ran PBK first before running YPAO on my AVR. I can't tell the difference wether it improved or not. As far as I know, it didn't degrade the sound, but that sub is fairly small.
I now have a different AVR that can eq LFE, but just to certain level, which I don't know.
I haven't bothered to eq either of my subs. I'm not too crazy about what YPAO did with my last AVR and won't be doing it again.
I won't be using my PBK kit again. When I bought it, my stepson had a pc, which is what operates the PBK, but he now has a Macbook, like myself, and PBK doesn't work with Mac.

I like the above posters who tweak their bass themselves. Maybe someday, I'll do the sub crawl, but so far I like what I hear and don't feel the need to atm.

Best of luck to you!
I feel like our ship's going down tonight.

I use the Velodyne Auto-EQ feature on my sub. I like it although I haven't played around with many of the preset values.
McIntosh C220 - McIntosh MC252 - EAD T1000 - EAD DSP7000 III - Castle Acoustics Howard S3 - Velodyne SPL 1500R - RGPC 1200C/400 Pro/400 MKII...and other stuff

With one sub, it works great. Two of the same model, you can get away with it if you're careful with room modes and things that affect room treatments.


Four - especially different models - and you've got a robot fight. You can try to sell tickets to it, but if you wind up like me, everybody will just throw tomatoes at you and cover their ears.

You have 4 subs, do you have them placed symmetrical?

Yeah, they're in each corner of the room, with the Fathom up front. They have noticeably greater output (and they come with microphones, the SVS units don't.) I still twiddle with everything, despite my wife giving me crazy looks. But I don't move the subs.

With two SVS Ultras running in there, you need to do something to tame them down. Otherwise your eyeballs will jitter and you'd have to go outside and look through a window to see a movie.

Ya described it perfectly.

For some reason I had a massive bass bump. For memory it was around 53hz. It was 13db hot. So the SVS EQ software was set to reduce it 12db. It has worked well. Not perfectly smooth but a tolerable solution.
