Yes Bob it is really amazing. I just have to figure out how to post my results on here. Any ideas?

Thanks
Patrick

Sorry Patrick, I'm not good with these things myself.
But I'm sure someone else will be able to help you out.

Ed or Kal perhaps.

Cheers,

Bob

Bob I did get it figured out. Look at the bottom of page 11

Ed,

The ASEQ1 is running much cooler now. Also I said that I am running the sub at 16 feet away and that is because the software said to set it at 16.3 feet. Should I set the sub at 16 and a half feet away. Thanks for the crossover information.

Thanks
Patrick

I'm not sure that I'm reading your post correctly, but if you're saying that you should physically move your subwoofer box to a position 16 feet away, then you're misreading the instructions. What it is telling you to do is to change the subwoofer distance in your receiver's setup menu to read 16.3 feet.

Hi Jim,

I have the distance in the receiver at 16 feet. I am just wondering if I should just make the distance in the receiver at 16 or 16 and a half feet away in the receiver with the reading at 16.3 feet.

Thanks
Patrick

Patrick,

If your receiver allows it, while playing content change the sub distance from 16 to 16.5 and pick the one that sounds the best.

Jim,

I am currently running at 16.5 feet and I am really liking it. I think this Saturday night I am going to change the position of the sub so the woofer and port face the room instead of the wall. I am curious to see what type of response and sound I get. With the sub facing the room.

Thanks
Patrick

Yes, I saw it, great. Now you just have to diminish the size of the graph "Before", so it match the size of the graph "After".

Hey Patrick, with some experience you'll become an expert at graphic design reproduction.

Good job,

Bob

Don't forget to rerun the AS-AQ1 for your new Sub small position change.
The distance should be very similar though, perhaps only a few inches closer.

Hi Bob,

I will definitely remeasure the sub facing the room instead of the wall. I hope it gives me a better response. If it doesn't I will turn it back facing the wall and remeasure it. I am excited to see the results.

Great Patrick. I'm also curious to see the results. I ponder... But I think, you'll be pleased.

The recommended subwoofer distance is a combination of the acoustic distance plus the electrical latency of the AS-EQ1 (about 8.5 ms).

So if the recommended subwoofer distance is about 16.5 feet, the subwoofer is probably about 8 feet away from the measurement location.

All of your speakers are sealed with a 60 Hz extension rating. So use a 2nd order high pass, a 4th order low pass, and a crossover frequency of 60 Hz.

Ed - Did you have any opinions on the crossover setting for my Kef Reference 3.2's - They are rated flat to 40Hz and LF Corner -6 dB 36 Hz

Many thanks

I would absolutely check the absolute polarity of both subwoofers before attempting to acclimate your ears to the system.

Even if you skip calibrating both subwoofers to the same level, it will still be painfully obvious if they are reverse polarity when placed side-by-side and fed the same rumble tone. The SPL will tank noticeably and they will fight against each other. Conversely, if the SPL jumps noticeably (it would be +6 dB max if the two subs were the same SPL/model/tune), then you are OK and put the PC+ back and carry on.

If they are reverse polarity for some reason, switch the leads on the PC+ woofer, not the Ultra. Contact in TS for the procedure on how to safely remove the woof.

Mystery solved: "Turn up the volume stupid!"

I broke out the Radio Shack meter to check if the subs were wired right. They were. Since I had the meter out and mounted in my listening position, I figured I would take some measurements after I put everything back the way it was. A couple of weeks ago, I spent some time with my Oppo BDP 83 trying to see if there was a difference between outputting bitstream or LPCM to my receiver. There wasn't. I had the meter out to make sure I wasn't influenced by the volume.

This time I cranked up the volume up to the same SPL I used for my Oppo tests and all of a sudden, the bass impact was back. When I looked at the volume setting on the receiver, I realized that it was higher than I've been listening at after I installed the AS-EQ1. Normally I adjust my volume until I can hear the dialog clearly and don't set a specific volume on the receiver. With the AS-EQ1 cleaning up my mid-range, I didn't really need to crank it up as much to hear the dialog. I know now to turn it up a few more notches.

After living with the AS-EQ1 for a couple of days, I've had some time to reflect on what $700 bought me. Afterall, it's something I spent about an hour with and probably won't touch again for a very long time. The truth is, the $700 is a fraction of what I have spent on my speakers and components. I can't think of any component that I could have spent more on or added to my system that would have improved the sound quality as much as the AS-EQ1. If you don't have bass traps and acoustic panels, spend your money there first. Afterwards, buy the AS-EQ1 to extract every last bit of sound your system is capable of.

Glad to hear the subs were the same polarity.

The absolute SPL of the AS-EQ1 mic and SubEQ application will vary somewhat compared to other references like your SPL meter and AVR auto-EQ mic. So use the AS-EQ1 to level match the speakers and subwoofer, and then run the EQ routine.

If you discover that the overall playback level is a few dB different than it was previously for a given master volume setting, then you have two options: 1) make a global trim level adjustment to all channels to restore your previous reference level, or 2) simply adjust your master volume higher/lower to duplicate what you had before. Obviously #2 is easier and faster, as you discovered.

While calibrating to a known reference level is ingrained into our HT psyche, the lack of industry standardized encoding/mastering levels for DVDs pretty much makes reference level calibration a waste of time. If every DVD and every codec played at exactly the same volume, then sure - the concept has merit. But they don't - not even close - so we're constantly adjusting our master volume to compensate. In the end, it's far more important to level match than it is to calibrate to a reference level SPL - so that's what we recommend to customers and then advise they simply select option #2 above and adjust the master volume to taste for each DVD.

The AS-EQ1 was designed for users like you (and you represent the vast majority of our core demographic). It provides the best possible bass sound quality with a minimum of learning curve or user tweaking. That saves money, time, and aggravation and it lets the enthusiast get back to enjoying the hobby of music/movies instead of spending countless hours tweaking/measuring/tweaking/measuring. When you compare the price of the AS-EQ1 against peace of mind and your new found free time, it becomes rather reasonable indeed. And your comments have already been echoed by hundreds of users at all corners of the globe.

As one who has spent countless hours tweaking/measuring/listening/tweaking, and thinking I had gotten a great result, let me add that not only does the AS-EQ1 make it easy to EQ your subs, it also sounds far better than anything I had achieved previously with REW and a DCX2496. Night and day.

Ahhh... Thank you for the correction. Now, that makes more sense. But still, that much of a delay?

Hey Ed, is there a sale coming soon on this? Summer sale perhaps.

But seriously, I also have two big subs, and it seems to be the ideal solution.

I really appreciate your time and effort to explain very precisely to all members and owners here.
It is done very professionally. And only a true PRO can do this the way you do.

Thank you,

Bob

My apologies if this has been answered before, I have to admit I’ve not read this entire thread.

I’ve just ordered one of these units, but am wondering if the outputs are muted during power on/off?

[Gard]

I'm setting up a new HT room with MTS/MCS, PC-Ultra/EQ1 and Yamaha Z7. Any tips on the setup. Should I start with the normal 80hz x-over or would a 60hz or 40hz be better.

Gard - if it were me, I'd set the x-over higher rather than lower and let the PCU + AS-EQ1 do their thing at the low end. You can always experiement and see what sounds right to you in your room.

Cheers,

Doug

Was it ever determined how much smoothing was applied to the graph?

For that matter, has anyone posted a REW graph of a smooth AS-EQ1 graph. I'd like to see what the uglies look like.

Here is the REW graph of before (Blue line) and after (green line) AS-EQ1 calibration. The graph is smoothen to 1/3 octave.
I have Integra DTC-9.8 and single SVS PB2+(dual 12 woofers) sub.
One thing in the graph that I want to understand is the dip at about 35Hz in the after graph .


So far i'm pleased with the result .

One think I'm not clear is when EQing with AS-EQ1 should the Processer Audyssey EQ be turned on or off. I left it on.

[JimP]

Is blue the before as it looks more like it would be the after. On the Audyssey generated graph, did it show the after as being perfectly flat?

Also, if you're using a 80hz crossover, reverse the polarity of your subwoofer. It looks like its cancelling the mains at the crossover region. Then rerun Audyssey.

Yes the after graph by AS-EQ1 was prefectly flat. I'll post that graph later as I don't have access to that graph now.

The before graph(blue-line) is without AS-EQ1 and using the processor built-in Audyssey MultEQ XT. I've also attached the graph (purple line) that shows the graph without any EQ.

• I calibrated the system using MultEQ XT using the patch cable from AS-EQ1 to the processor. MultEQ XT gave a sub level of -1.0 db and distance of 6.4 ft.
• I modifed the sub level to 0 db before taking the measurements with AS-EQ1. Should the level be left at what MultEQ XT calibrated at
• Then I level matched all my speakers & sub(adjusted the gain) at 75db using SubEQ test tones.
• I set the speakers to "Full Band" large.
• Then i calibrated the sub using AS-EQ1
• I got a trim level of -4.1 and distance of 19.3 ft.

I thought the phase is automatically set by AS-EQ1 Do i need to do something different.
