"Official" Audyssey thread (FAQ in post #1) - Page 1776

Yes, though I just edited my post to correct "I would do this" to what I meant to say ... "I would not do this."

I've never done it, and wouldn't, but it should work. You may need to be watching the speaker as you make contact with the battery.

I once touched the rca with my finger with the amp hot (accidentally) .... it picked up enough ac to scare the h--- out of me. However, my sub amps have fixed gain so are always at max gain.

If I were to do this test, I would start with the sub amp gain quite low and raise it until I could see the cone move.

I agree fully. The idea scares me as noted above.

I think you're just trying to get out of buying me that cold Hungarian beer

Just kidding - I have removed my post in case someone tried it and destroyed their speaker and started a Class Action suit against me....

EDIT: Look what I just found when looking for something else on Ask Audyssey!! WARNING: Do not try this at home (go round to a neighbour's).



Those PhD's eh?

Then do we really need 24/48 or 24/96 on our Blu-rays?

Jeff or Keith, do you have a link to the "debunking thread", please?

Sure, AJ. Here it is:

It's an interesting ride

Thanks, Keith!

That is wrong information from Chris to poor Fred, but that's not why we like him, eh? He got his PhD in acoustics, not electronics!!

Electrical Engineering, Feri.

Thx.

Since it's Friday allow me a joke related to the subject.

The kamikaze trainer is telling his trainees: "Watch me carefully, coz I will only show you once"!

So it would seem!

Yikes... never thought I'd see the day...




Just joking around, no offense meant.

Lol, thx for the laugh.

I've been looking for Fred's post in the sub threads - the one beginning "I have this blown sub...."

Having replaced my Triad Gold LCR's with Gold Monitors, I now appreciate the Music vs Movie option for Audyssey. I've also realised the difference that Dynamic EQ makes for Music is pretty big. I definitely prefer it on for both Movies and Music.

The subtle details that the Gold Monitors are re-producing are absolutely amazing. The Gold LCR's were doing (what I thought) was an amazing job, but the Monitors are seriously detailed and life-like. I really can't wait to get my new Subs and run the Pro calibration - hopefully next week.

I'm off to watch some movies.

Way to go mjf! Glad this worked out for you in the end. I spotted you had sold the Gold LCRs ('sold' here being a euphemism for 'giving them away'). Sounds like a worthwhile improvement though.

Thanks Keith. I was rather worried about selling them for such a low price, especially as I'd never even heard the Monitors - so had no idea what difference I'd actually be paying for. Now that I've re-calibrated and tried some of my usual test material, the difference has definitely been worthwhile.

HI Audessey experts..
I ran Audyssey with my Onkyo 5508 pre-processor multiple times with the microphone at ear level. Every time Audyssey seem to have cleared up my low end response, but it bumps the HF response which is already high without Odyssey(+8DB). I was expecting it to tame the HF, but it's doing polar opposite. How can I rectify this? The PRO version is out of my budget a this time, but I thought XT32 included with the processor should at least get me in the ballpark. Thanks for your help.
PS - The measurements are taken with REW software with Radio Shack Mic with calibration file.

I have the exact same issue with my Onkyo 709 with XT. I have run at least a dozen calibrations following Audyssey's guidelines precisely, and no matter how I tweak each calibration, the treble is too hot. It sounds better with Audyssey engaged, but it is too bright...........My fix is to use THX Cinema mode for everything except music, and that has tamed the issue.

It may have to do with the height, aiming and FR of your front tweeters. Are they above, below or at ear level?

I just got following response from Chris since I had posted the question in 'Ask Audyssey'. Well, time to get a new Mic, I guess. On the other hand I'll get a chance to compare AUdyssey with Trinnov in next few days as well.
=====
I'm sorry, but the RS mic is totally inadequate to draw any conclusions from--even with a so-called "calibration" file. If you have followed the Audyssey instructions on where to place the mic then you will get good results:

If you measure too far off the center line then you will have a peak in the high frequencies because MultEQ will try to overcorrect for the drop off in tweeter response. Also make sure that the speakers are pointed to the listener's ears.
===

My L/C/R are all mounted above ear level (I like a raised sound stage), but they are all tilted down, and toed into the MLP. I used my laser to aim each speaker. My Yamaha with YPAO sounds much better in the upper ranges, but it's not as enveloping, and the bass is no where as good as the 709 & Audyssey XT.

My Triad Gold Monitors are all angled up at me, but after some testing I found that the left and right were better if just toed in slightly rather than firing directly at me. I previously worked out where the 'too far' off axis point was with the LCR's, so I'm careful about mic placement.

My LR tweeters are at the ear level where the microphone was placed as well.

But the mic's polar response does not match that of your ears. I would tilt the mic so that it is orthogonal to the radiation axis of the front speakers. The reason for the normal recommendation to point it to the ceiling is to have it orthogonal to the speaker radiation and you should try to approximate that while keeping it at ear height. This might lead to some strange issues with the surrounds but it is worth a try.

Thanks for the suggestion Kal. I'll try that out in next couple of days. Will it make a difference if my tweeters are ribbon?

Perhaps. Audyssey assumes that the mic is on and perpendicular to the radiation axis of the tweeter. If the ribbons are tall, there are, often, variations in the vertical plane.

For the folks with boosted HF response, what are your room sizes? Larger than 2500 cubic feet by chance?

My room is very small, but I was experimenting.

Is this a known issues in larger rooms? With opening to the dining area, I would say that the room is about 2700 cubic feet..
