Hi,
I recently moved into a new house and discovered that my sub's have really ugly spikes around 61hz and 41hz, and dips around 28-36hz(the sweet spot for rumbling bass ;-)). I'd like to even them out. Do you guys have any suggestions as for a good quality and yet affordable EQ for this?
I've looked at the behringer stuff, but there are so many models for EQ related issues that I cannot figure out which one is best.

My system is as follows:
Reciever: Yamaha rx-z1.
DVD: yamaha c750 and sony ns700p.
Speakers: M=paradigm studio 40's(v3), C=studio cc570(v3), S=ADP-590's (also have studio 20's(v3) as alternates).
Subs: Two SVS CSplus 25-31 tuned around 20hz, running off a Samson two channel 1200 watt amp.
TV: Sony wega KDF-E42a10 42" LCD.

Thanks a bunch for ideas you may have!

Take a look at the Anti-Mode 8033. There's a thread on it here on AVS.

I have the Anti Mode 8033 and it is easy to setup. It takes 5 minutes and you are ready to go. It is strictly a sub EQ and works well. Here are a few sites to check out: http://www.avsforum.com/avs-vb/showthread.php?t=1028464, http://www.avsforum.com/avs-vb/showthread.php?t=1048461, and http://www.hometheatershack.com/forums/bfd-forum/11699-testing-dspeaker-anti-mode-8033-a.html.

Good Luck, Bill

i also have an anti-mode and am very happy with it...

Before you EQ, make sure you have the subs and the listening position in the best possible locations. Also, play around with relative phase between the two subs to get them as close to in-phase as possible at the LP. Also, address room acoustics with bass traps if possible.

If, after all that, you still have some resonances, then EQ is worthwhile. My favorite is Audyssey MultEQ XT because it EQ's in both the time and frequency domains. If you use something like a Behringer, be aware that you can't boost true "nulls". If you add power to a null, you just push that power into the "black hole" of the null. It wastes power and doesn't help the problem. Also be aware that most parametric EQ can only EQ one listening position. They can potentially make other listening positions worse.

Agree if you have Audessy MultiEQ XT it will help but you will most likely have dips you need to address first by placement, Phase and or sub distance adjustments.

Once you have the dips addressed you will most likely have peaks even with Audessy running that will need to be tamed.

No matter what you choose I highly suggest learning REW, the Hometheatershack.com is a great source. Once you have REW figured out then buying a BFD DSP1124P will allow you to address the peaks. BFD is $99.

I have a Denon 2808CI and Audessy does help but not the entire low bass range.

Learn to generate and read graphs, you will not regret it.

Without something that lets you look at your room response you are just guessing,

Thanks a bunch for the replies everyone! Currently I have my subs on either side of my entertainment center/TV, and my mains outside of those. I've tried moving the subs back further which didn't help much, nor did moving them further into the room. Asthetically and practically I'm kind of limited in where I can position them.
I'll take a look at REW and see what I come up with. But I have run a test with some wave software to analyze the peaks and valleys as well as plotted them using avia's sub test proceedure with an SPL meter. The peaks are around 60hz and 41hz with null spots between 25ish and 35ish(the normal sweet spot for rumbling bass).

Also, I see alot of different EQ's on the behringer site, is there a particular reason to go with the DSP1124 over the others? Keep in mind I'm sending an analogue signal out from my reciever to my sub's amp - so re-digitizing it for processing might erode the sound quality and introduce a delay I suspect?!?

Oh, the Audessy device is out of my price range unfortunatly - I spent a fortune on the rest of my gear and simply can't afford the audessy!


Thanks again for everyones help!
