Svs as-eq1

[sbisheff]

I'm sure most of you have already seen the thread on AVS regarding this piece, but I just found it and thought I would share. It is meant to be a step up from the SMS-1 was built in conjunction with Audyssey. SVS is bringing out the "consumer" version while Audyssey is bringing out the "pro" version to custom installers.

Here's a link to the AVS thread: http://www.avsforum.com/avs-vb/showthread.php?t=793007

PICS :D

How is this better then Audyssey on a receiver? They seem to be measuring the same thing, except the above is only handling the sub portion. I'm guessing the testing using the as-eq1 involve lower frequencies, but...?

Also, if you run Audyssey on your receiver, do you run 5.0/7.0 and then run this?

[sbisheff]

I don't know the exact details, but I brief understanding is that it does what Audyseey MultXT EQ does, but in MUCH more detail. It adjust both time and frequency and I think I read has 32 possible placement points (vs. normal Audyssey which has up to 8).

I think I read you run the SVS piece first then when the Audyssey on your AVR pings the sub channel it already reads as perfect.

Hey Scott,

I'm watching it too, especially 'cause it preports to work integrate two subs, including phase. But I've got to admit right now I'm starting to play around with REW and the concept of a house curve for the subs, while the SVS will only do "flat." Besides that is the expense diff between it and REW plus either RDES (my current) or a Behringer (I'm considering).

enjoy!

Only for subs? I thought SVS was bringing a unit that did full range Audyssey in a standalone unit. That'd be of more interest to me.

Comparison of subwoofer eq programs and/or gear

I'm interested in this product, so started making a word file for myself to compare a bunch of products.

Here is my evolving comparison list...

Potential EQ equipment and Software
- REW
- True RTA
- Acoustisoft ETF
o Rubinson, Kalman, 7/1998 – Stereophile – on ETF4 - http://www.stereophile.com/miscellaneous/277/
- Velodyne SMS-1
- AV123 R-DES
- QSC DSP-30 (Seaton site)

Mike,

I paid for ETF (opted for it over RTA for what I wanted to do), and then got REW for free. I MUCH prefer REW. Besides the simplicity, its inclusion of comparison lines (flat, or set up your own programmed house curve), calibration curve for the RS SPL meter, and the ability to model the effect of PEQ settings on the current data, and for some of the PEQs directly download it - all that makes it a slam dunk for me.

Even if you get the SVS eq (which sounds GREAT!), it's a great measurement tool. I slopped along trying to record meter readings from freq sweeps - remote in one hand, spl meter in another, pencil and paper in another; trying to look at the frequency on the screen, the meter reading, and record it all at once in real time. Get the idea??? I could kind of figure out where the peaks were (within 3-5 Hz or so) and maybe how large they were, but had no chance with the width of the hump. And then there's the cancellation valleys! :no clue:

Now it's fire the measurement button and look at the graph - err graphs! Can also look at multiple graphs and compare them simultaneously. Can measure the peak freqs to the single Hz, get a picture of the number and depth of interference valleys (a large help when trying placement for two subs). And besides also visualizing the width of each of the peaks, being able to model the affect of the PEQ width setting ends up being what is actually important. No matter what you use to perform the equalization, let me recommend this tool if for no other reason than independent confirmation.

I'm using R-DES for the actual equalization. REW had a button that let me mimic R-DES for the parametric modelling. All I did was transfer the settings over to my R-DES. The results: :cloud9:

or should I say :rock:

enjoy!

P.S. I honestly like REW so much that while it was free, it's worth much more than ETF was - so I'll be making a donation.

[Eric D]

P.P.S. I'd also throw the BFD onto your list of options - relatively inexpensive, and if you decide to get REW it's supposed to work together pretty seamlessly (like my R-DES does).

Thanks.
Good info.
If I think my list/table has any general utility I'll post it after I research some more.

I think you are correct that I should do some measurements first.
My room might not be too bad at baseline as it was designed by Rives Audio, so hopefully isn't terrible.

More later...

The DCX2496 is a little better alternative to the DSP1124P because it provides a few other capabilities which can be useful, like channel routing and shelf filters. In most cases those features aren't of much use, but in a more complicated setup or for a DIY subwoofer they're great to have.

Cool.
I'll add to my "database".

I can't wait for this to arrive--the ability to handle two different subs(or more if colocated) is great. Anyone want a cheap DCX2496??? :yes:

[NekoAudio]

Before you get rid of your DCX2496, you might want to experiment to see how well the AS-EQ1 does.

Remember, you could keep running the AS-EQ1 to see what filters it assigns, stick them on the DCX2496, re-run the AS-EQ1 to see the new filters, stick them on the DCX2496 again, and repeat until the AS-EQ1 says all done!

Because I'm betting the DCX2496 has more filters available (18 normal, 54 chained) than the AS-EQ1.
