Does any body know if you can tweek the thing (house curve or change xover ect). I have the sms-1 now and its pretty handy to be able to change the xover point as well as the slope as steep as I wan't. Does it have a volume control??
I have 4 cs ultra's and I love the idea (running them in pairs off of a ep2500) of dual subwoofer control!!! No more time delay-phase issues

The AS-EQ1 is not a bass managment tool - it does not have a low pass filter or a level control (although it does have speaker/sub level-matching capability). It gives your subwoofer(s) the flattest possible FR (which is not adjustable) for a given location and listening position.

This is a very exciting product, I was looking at the anti-mode but I think this may be an ideal product because of the 32 location measurements.

I was curious, for those with more then two subwoofers would it be possible to split the channels off the AS-EQ1 with an adapter to accommodate 3 subs or maybe even 4? I currently have 3 with an iffy room response and do not want to give up using one.

Thanks for the info!

The AS-EQ1 has dual subwoofer feeds and it can be programmed for either dual mono or dual discrete. You can certainly operate more than one subwoofer off each channel by using a Y splitter. So 4 subs (2 discrete channels using a splitter at each channel) are not a problem.

We offer a 45-day in-home trial, just like for all SVS products. All you risk is forward/return shipping.

Ed,

Could you tell us more about the speaker matching feature? I saw the Center/Left jack and figured that was what it was for. I have a Pioneer with MCACC and concluded that the "pings" the EQ1 gives back to the receivers room correction system would only work with receivers equipped with Audyssey. I am hoping that I can get my speakers dialed in with Advanced MCACC and then blend in the subs with the EQ1.

The AS-EQ1 will work fine with your MCACC system. When the Pio pings the subwoofer, the AS-EQ1 will route that signal back to the Pio mic input jack. So the Pio sees a perfect subwoofer signal and won't build a correction file.

After you run MCACC, level match the subwoofer to one of your front stage speakers using the level matching feature. This sends a broad band pink noise signal to the speaker (select an analog input on the Pio) and a rumble tone to the subwoofer. Adjust the gain on the subwoofer until it matches the speaker and then run the AS-EQ1 routine.

You can skip the level matching step if you have already set the subwoofer level to match the mains via other means (like manual test tones and an SPL meter). But don't allow the MCACC to set the subwoofer level because it will also build a correction file at the same time.

Just to clarify, then: there is no way to enter a "house curve"?

I am continually amazed at what people think is "affordable." Maybe there are AS-EQ1 giveaways in the new Big Bill.

Looks very nice, though.

Correct - no user adjustment of the corrected FR. If you want that capability, you are better off with a different product, or cascading a shelving filter over the corrected AS-EQ1 response.

[CharlieU]

Thanks for the information Ed. This looks like it will be a very sophisticated device and has the features to separate itself from the "pack". I look forward to putting away the RS Meter and Rives CD and spending the the time doing something less frustrating, like play golf.

[robbroy]

Yer right I'm in line for one of these, recession or no! They say you gotta' watch your money, but I say you also have to listen to it! At the last home theater get together I had Ron brought one of only two working prototypes to run with my dual PB13-Ultras. Sounded amazing! Then the rat (JK) took it home with him! I've missed it ever since... If it has the same excellent fit and finish as the rest of their products (remember, I only saw the prototype) it will also look good in the rack.

Or using the AS-EQ1 with a processor that supports AudysseyPro v3?

Sure - any upstream device can cascade over the AS-EQ1, just like the low pass filter applied by the surround sound processor.

Ed - since I have a BFD as my current EQ device, why couldn't I run the AS-EQ1 to flatten the room, then use the BFD to create an inverse house curve (mirror image of desired HC state), then run the AS-EQ1 to flatten the room again. I would think I could then remove the BFD just using the AS-EQ1 and find I have a house curve.

Would this work?

Thanks,

That's a pretty cool idea. I never thought of it but it seems like it might work. Very interesting.

[JimP]

If you're going to do that, then why go to the expense of getting the AS-EQ 1? Just use the BFG

[jagman]

Just out of curiosity, aside from being able to independently control two subwoofers, what is the benefit of this device over using the regular MultEQ XT embedded in a receiver or Pre/Pro? I ask because although not ubiquitous, MultEQ XT is pretty common. Does it perform better because it has a stand alone power supply and the processor is devoted solely to the Audyssey software? Since it likely has the hardware to support house curves (like AudysseyPro V3.0), I'm a little surprised you chose not to include that feature set since most subwoofer enthusiasts (at least on the online forums) like to use a house curve.

Probably because it is easier to control dual subs independently plus the sweet spot is considerably larger.

[Roadkill]

Some of us use balanced interconnect cables. Will you be adding balanced in/outs at a later date?

Thanks - I didn't see why not. Thought I'd ask Ed and see if there was any reason why not as well.

At one time, before I got into EQing dual subs, I had hair. I have no hair now . Even though REW took some of the tedium out of it, I'm betting the AS-EQ1 can get way closer to flat than I can or even want to try any more when the room changes and I have to do it again. I think SVS invented this device for me as their (almost) demographic.

However, since I rarely listen at reference and I've experimented with and without a HC in my room at lower levels, I'd think I'd find the low end a bit down for my taste. I know I could also leave the BFD in between the AS-EQ1 and the subs and boost to get the HC and then put the BFD into bypass if I didn't want the HC applied. I also thought I could fool the AS-EQ1 into supplying the HC using cuts on the AS-EQ1 correction if I wanted to take the BFD out of the loop for whatever reason, which is why I was thinking I could fool it with an inverse HC. I'll try it and let you know but thought I'd ask Mr. Mullen if he had any thoughts.

In any case, as Will Smith said in Independence Day, "I gotta get me one of these!".

Ed, will the AS-EQ1 display the before and after bass frequency responses, either on the device itself or when attached to a PC?

[TheGovernment]

this devise sound pretty sweet! I'm not liking the no balanced input/out puts though, that's not good.

It might work in theory, but the AS-EQ1 does have an overall boost limit for two reasons - 1) it needs to avoid digital clipping/headroom issues, and 2) it also has a sophisticated roll-off sensing algorithm and it might view an aggressive inverse house curve as an inherent inability of the subwoofer to maintain a flat extension to its corner frequency. In other words, it may not indiscriminately apply boost to completely overcome an inverse house curve.

The AS-EQ1 has more processing power and filter resolution than the consumer version of Audy MultEQ XT. It can also measure in more locations (up to 32) if you have a large room and listening area.

The problem with a "house curve" is that it's a static solution which only works at one playback volume. It may be inadequate at lower volumes, and it may be overly intrusive at higher playback volumes. Hence the introduction of Audy Dynamic EQ, which applies a continuously varying bass "house curve" (i..e, compensation for our relative insenstivity to deep bass) as a function of playback volume. This is a far more elegant solution that the static/fixed house curve applied uniformly at all playback volumes.

So if you value the concept of a house curve, and you want to take it to the next level (including the speaker channels, and not just the subwoofer), then get a processor which features Audy Dynamic EQ.

Yes, on the PC screen and as an HTML file saved in the Audy program file folder. You can even share this document with others by saving it as a PDF with CutePDF (freeware).

You can check as many combinations of subwoofer location/listening positions as you want, and when you find the best result, then you can permanently save that correction file to the AS-EQ1 and disconnect the PC.

Ed - is the AS-EQ1 capable of Dynamic EQ and if so, any thoughts on enabling it down the road or for a small fee?

No, we never envisioned applying DEQ to just the AS-EQ1 because this Audyssey feature affects all speaker channels (not just the subwoofer). If you have not experienced the effect of DEQ, it is quite startling, and the variable house curve it applies to the subwoofer is just a fraction of the overall experience/effect.
