I hope to see how it does over a row and two rows of seats soon. If anyone has a specific test they’d be interested in let me know and I will try to work it in or pawn it off on Sean later. I'd be very interested in hearing your results regarding multiple rows and/or seats. Hopefully I can get to that this weekend as I looks like our fun and games at work are getting pushed back at least to Sunday.

LOL! That's good to know about Avatar as we were puzzled why others seemed to be raving about the bass. Still, just the M80s alone was pretty impressive.
And they weren’t even playing the LFE channel since the Onkyo still thought the EP500 was working since I never deselected it in the receiver.

Would someone generally be better off buying an EQ like this, or buying a second sub? I know the second sub will help level frequency response, and increase headroom and output, but I can't imagine it would help as much as the EQ assuming you have ample headroom already with the single sub? Those graphs are pretty impressive.

Gasmdude, for a lot less than $800 you could look at something like the Behringer Feedback Destroyer (and yes, it is a bfd)as an inexpensive but effective parametric EQ.
It is not automated and requires measuring software like REW, but the results will be the same.
The cost for the BFD and a mike, or spl meter will set you back 2 bills or less.

I have a similar question to potatohead...would it be better to but this EQ than a better sub? I have a not too too bad sub now, and that EQ is a few hundred less than the ones I've been looking into.

Dean. Wow, thats some mid bass suckout you have there! I had the opposite problem a hughe midbass peak at 54Hz. left me with less rumble.
Though my peak was just as bad, the effects of eq were much more subtle. I got more rumble and more detail in the upper bass, but it was not night and day when I first tried it. I find I am more sensitive to it now that I am used to the extra detail.
I'm also surprised that you're EP500 starts to roll off above 20 Hz. My EP350 has the same roll off. I guess I just get a lot of room gain here in my concrete bunker.

come on Grunt, don't you know that using such Audyssey products is a snake oil technique. You know I'm kidding, great results. EQ is a mixed bag. It is very effective for recalcatrant issues in the sub bass region, but generally does nothing for higher frequencies.

I agree that the graph is very impressive but remember that was only for one seat in the sweet spot. Today I gave a listen in the seats I hadn’t run the EQ for and the bass sounded worse than I have ever heard it (remember I only ran the EQ for one seat). I imagine that to EQ multiple seats the final curve will not be nearly so good since it will have to average things out across the whole row(s) and right now the “perfect curve“ for the sweat spot is clearly screwing up the adjacent seats. I hope to re-run the EQ across both one row and two rows of seats Friday after work, just to much going on right now to do it sooner. Hopefully I can get Sean over hear fairly soon with his two identical subs so we can compare how the EQ1 does over multiple seats vs two subwoofers and since it will EQ two subwoofers we can also do two subs + the EQ1. My understanding is that because no one curve can be ideal for all seats it’s usually better to get a second subwoofer before applying EQ as it will even things out better so that the EQ doesn’t have to do as much should you also choose to use it.

Yes it is a big hole in the midbass which is one reason I’ve been toying with the idea of midbass modules but I’d rather have a more all encompassing solution before going that route. Fred how many bands does your BFD have, and can you set them any way you want so if you want a bit of a midbass hump you can dial that in? Also, I assume one BFD will only EQ one sub is that correct. Plus does it help to properly set the timing delay. Another big improvement I’ve noticed is that the M80s and EP500 seem much more closely matched timing wise with the EQ1 compared to the Audyssey in the Onkyo. The tweaker in me would like to be able to set up my own target curve so if say I want a midbass hump I can put it there since I can still get plenty of very low end with my Buttkicker. I haven’t researched to see if the Pro version allows user defined target curves but my understanding is that it does.

The BFD has 10 eq channels and two lines in/out.
There is a process for EQing multiple subs on one channel and REW can help a lot there, but it is a manual process. I think the big value of the SVS EQ is that it is automated.
Now, REW will generate EQ settings from a set of measurements, so EQing one sub is as simple as running a sweep, clicking a button for REW to generate an EQ curve and then manually entering the settings given by REW into the BFD. It took me about an hour to figure out the setup and enter the settings the first time.
