In theory.

Someone will have had to of found the discrete codes and posted them somewhere (Remote Central is a good resource)....but yeah, you can typically find discrete codes for a lot of functions not available on the factory remotes.

But, you have to have a remote that will accept those codes....I think the Harmony's can do some, but I use a URC MX-800 (that I've been using for 10+ years) that I can pretty much use any hex code with so I'm not sure of others.

Dyn EQ is meant to deal with how humans hear at lower volume levels, not to reproduce any "industry-standard".

I've had my Klipsch speakers for over 20 years and have always used Cinema EQ...works for me in my system.

It's hard to know how much your room might be a factor in the equation and whether some discrete acoustic treatments might help. But you mentioned microphone height and that has definitely been a factor in my case. Our ears are actually a little lower than we think they are--at least 5.5" down from the top of my head to the middle of my ear canal in my case. And until recently I was pretty consistently using microphone positions that were a little too high. I have found that making very sure that the mic. positions are a little lower--just 2-3" lower gets them to the middle or bottom of my ear canal--has helped to reduce the perceived brightness in my room.

It's all so speaker/room dependent that mic. height might be a minor factor in some calibrations, but it seems to help in mine. Of course there can be trade-offs with respect to a clear line of sight to your surrounds or rear surrounds; fortunately not a factor in my case. But if it were a factor, and I had to choose, I would probably optimize the sound for my center and fronts, and accept some degree of compromise for my surrounds. I would naturally have to experiment to determine how much compromise I was willing to live with. But the FAQ suggestions, the center speaker angle, and the mic. height at least give you a methodology for experimenting to hear what works best for you.

I also have Klipsch speakers, which are fairly bright to begin with (but good, and with great dynamic capability and very clean, precise sounding transient response). With modern movies on Blu-ray, they sound very good with Audyssey Flat, and even better with Audyssey Reference (i.e., with Audyssey's midrange correction and moderate high frequency roll off). I almost never use DEQ, and almost always run movies about 3 to 5 dB below Audyssey determined Reference Level. The movies sound very dynamic and exciting, with strong, sometimes overwhelming, bass.

Now with older movies of the magnetic Hi Fi Stereo era (certain, but not all, movies after 1953, especially 70 mm movies) it's a different story. IMO, the people who transfer these to Blu-ray often do not use anything near the bass EQ the studios used to use in preparing release prints. During the original recording sessions, great care was taken not to over-record, so some bass roll off was often used both in the boards, and at the microphone roll off switches. When the final mix was made, when it was less expensive to try over and over again to get it just right (since musicians and sound effects guys were not sitting there being paid during the mix down), the bass was restored, sometimes boosted even more, and the dynamics fine tuned. Even though theater systems typically started to roll off below 40 Hz, some very dramatic bass (about 40 to 200 Hz) found its way to the theater audiences, if they were lucky enough to be hearing a magnetic soundtrack. When Blu-rays are made from these old soundtracks they understandably try to go back to the original, first generation, magnetic sound elements -- which have rolled off bass -- but I strongly suspect they fail to put the bass back, perhaps because they are too young to know what these films sounded like in the theaters. The latter may sound far-fetched, but the BD supervisors are the guys who allowed the resolution of the faces in Patton to be softened, and had to do a new transfer when the complaints came in. If they can do that to the image, there's no telling what they might do to the sound. So, for films of that era, I turn up the bass, when I can. DEQ doesn't seem to solve the problem for me, so I use other means. The sub is easy to turn up, but that stops helping somewhere above 80 Hz. My pre-pro tone controls (not virtual sliders) allow me to turn up the bass by about 6 dB. Since Audyssey actually cuts the bass down a little in my room, with my speakers, with these magnetic era movies only, I sometimes turn Audyssey off.

Unless you have the ability to measure your room's response, it's best to trust Audyssey on sub distance. If you have a mic and REW (or similar) you can adjust the sub distance in the AVR until you get the smoothest transition through the crossover region, but without measuring gear there's no way to know what distance is "correct".
Ok thanks Alan, yes i mean phisical distance. but how does that work as i noticed that my speaker distances were at the correct distances but my sub was set at a greater distance although the sub is about 2 feet away from my speaker but the distance was far greater. Why does Audyssey do this?

Hi gentlemen/ladies,

I've been reading up on as many posts as I can over the last few days. And whilst I love all things tech, HT, sounds etc, I will be the first to admit that some of the things that I've read have gone way above my head.
And I need help translating and dumbing down of some things. So please bear with me if these questions have already been asked.

My current setup consists of the following: Anthony Gallos 3.5 Refs, Strada center, 2 x Adiva TI, Anthem MCA 30, Anthony Gallos SA Amp and recently a current(2013) Denon AVR.

When running the Audyssey calibration, I was asked to turn up the woofers so that it hits 75db. In order for me to do that, I had to up the gain and the boost on the SA Amp to pretty much maximum. Even then I've only been able to hit around 72-74db on one woofer.
The other woofer does occasionally go 75-77db.

Is what I am doing correct?

I also noticed that in the crossover section, my font speakers crossover at 110 and my center 150.
Looking at my speaker manuals, it's asked me to set it at a different level - not higher than 100 Hz. Which one right?

Thank you in advance for taking the time to help me out here.

Something is wrong. Someone who knows more than I do will help. You should be able to get the 75 dB easily. Which one of the components you list is a subwoofer? Also, both 110 Hz and 150 Hz sound very high to me, for high end speakers, although in some rooms ...

Hei Gary. Thanks heaps. I just wasn't sure and that's why I thought I'd ask. But like you said, it could be because of my room. Will see what the others here say.

The reference 3.5s have their own woofer each. I've included an image link of the speaker below

http://www.anthonygallo.co.uk/img/im...35-cutout2.jpg



And just to provide more info:



1. That's the rear of the SA Amp. I've got the two RCA cables from the Denon (SW1 & SW2 preouts) connected to the Line In on the Amp
2. I've got my woofers connected to the Subwoofer output on the Amp.

Thanks again for your time. If more information is required of the setup to assist, let me know. Thanks again.
garygarrison's Avatar garygarrison 09:21 PM 07-11-2014
I'm assuming there is a separate input on your Anthony Gallos 3.5 Refs that feeds the woofer only, and that is what you have connected to the "sub out" on your amp. At what point do you have the crossover in the preamp (or pre/pro) set?

I'm only familiar with using Audyssey with a totally separate subwoofer that goes up to about 80 Hz, and main speakers that are set to go from about 80 Hz on up.

What configuration of Audyssey do you have? XT? XT32? Or some other? If it is XT or XT32, I think it can be used with a separate sub only. So you need Right Front, Left Front, Center, two surrounds, AND a separate subwoofer. Or do I completely misunderstand what you are doing?

Alan P's Avatar Alan P 09:45 PM 07-11-2014
Those are some....interesting (expensive?) looking speakers.

Having your subwoofer integrated with your mains is a very, very bad idea...always has been and I can't believe there are still manufacturers doing this.

You will be completely unable to get proper sub response because you have only one option when it comes to placement. An unfortunate choice in speakers for sure....is it too late to return them??

I have Audyssey MultEQ XT32 and Audyssey Sub EQ HT Dual Subwoofer EQ.
If what you are saying about the separate sub is true then I will need to rewire it with a Y cable like I was doing previously.

Bummer :P I thought I kinda had dual subs hehe. Hopefully someone could confirm that for sure. And no you are right on the money in terms of how I've set it up currently.

Hei Alan thanks for your input. I would say they are pretty reasonably priced. We were looking a full paradigm setup previously but my wife and I preferred the sounds on these more. The paradigms were far more expensive. Aesthetics played a part too as my good lady didn't want big chunky speakers in the living room.

As for the woofer, I guess one way to look at it is that it's a compromise? The woofers have been performing good enough for us in our current setup.;

Definitely will not be returning them and wouldn't be able to anyway. I've had them for a good 3 years now at least. And I am very happy with them.
Selden Ball's Avatar Selden Ball 03:59 AM 07-12-2014
Another way of looking at it is that they are indeed just woofers. 10" drivers are somewhat small when considering subwoofers, and the specs on their Web site does claim that they're already 3dB down at 35Hz. That's fine for music, but usually is considered inadequate for action movies. When placed in a room, the response is likely to be worse at your primary listening position. Getting a separate subwoofer would be reasonable if you want better low frequency extension.

Are you able to add a separate subwoofer?

The woofers in your speakers are probably very good but they can't have the deep-down ability of a decent, purpose-designed sub. They won't be able to play as deep and as loud (at the same time) as a purpose-designed sub, and almost certainly can't provide reference level bass for movies (115dB) cleanly and low enough (20Hz or lower at 115dB, say). If you only listen to music, this may not matter, but it does for movies.

Also, as others have touched on, the problem with relying on 'subwoofers' built into mains speakers is one of placement. The main speakers can only be placed in one position, for obvious reasons, and that is in front of the listener. This rigid placement option is rarely the best place for the subwoofer, whose interaction with the room is crucial. The ability to locate the subwoofer in the optimum location with regard to the room's natural modes is one of the great advantages of a separate subwoofer.

If you can add a subwoofer, it will enhance the listening experience greatly, and you can retain your current speakers with no problems at all.

Hei Selden. Thanks for that. Understand that getting an actual sub will improve the low frequency extension. But I guess what I am trying to confirm is:
1. Have I set things up correctly?
2. Have I used the calibration correctly? i.e. should I be using the dual sub option or not?

If I have done it correctly and that's really all there is to it, then I am happy with it. I am more afraid of wrecking something due to incorrect usage as oppose to getting more if you know what I mean.

In terms of speaker purchases this is it for this place. Not to mention I'd need to convince the wife to have a cube sticking out in the living room somewhere

Totally agree. But I am satisfied with what I have heard so far. I suppose ignorance is bliss at this stage seeing as I can compare what I am missing out on :P.

At this stage I am trying to confirm if I've understood and am using the setup correctly. I am more afraid that I am wrecking something because of incorrect application.

Thanks again Kbarnes.

OK, all understood. Your setup is unusual for this thread but I will try to give you my thoughts, based on Audyssey best practice.

AIUI, the subs in your main speakers have their own inputs, which appear to be speaker level inputs. They are fed by a separate amplifier. You are connecting the line level subwoofer outputs of your AVR to the line level subwoofer inputs on the SA amp. You are then connecting the speaker subwoofer inputs to the speaker level outputs on the amp. Do I have this right?

If so, then this isn't all that much different to a regular setup using an external sub. In that setup, the subwoofer outputs of the AVR would go at line level to the inputs on the sub's own plate amp, and from there (internally) to the speaker level connections on the sub drivers themselves.

The normal procedure then is to initially set the SPL to read 75dB in Audyssey, which is accomplished by telling Audyssey to play the test tone while you adjust the gain on the subwoofer amp. So the next question I have for you is, does your SA amp permit you to adjust the gain? If it does, then you need to adjust the gain in one direction or another until Audyssey reads 75dB from the mic. This is where I understand you are hitting the problem you described earlier.

First, please confirm that my setup assumptions above are correct. If they are, and you are connected the way I describe, it is puzzling that you cannot achieve 75dB from the SA amp even with the gain wound all the way up. I am assuming you have the Audyssey mic at the MLP, pointing to the ceiling etc, as described in the FAQ and/or 101 (linked in my sig)?

I can’t see the gain control on the SA amp - I assume it is on the front? Can you provide a bigger image of the back of the SA amp so that I can see the labeling better? Or point me somewhere on the net where I can see this? I just want to satisfy myself on how you are hooked up.

If we can get all these assumptions of mine clarified, then hopefully we can go on to do more investigating. It does seem odd, at first sight, that your SA amp lacks sufficient gain to achieve 75dB, so I am suspecting some form of user error or a faulty amp at this time. Hopefully it is the former.

If everything is setup correctly and you are certain the amp is not faulty, then we can look at the implications of this later. Also, we'll leave the XO issues until we've gone as far as we can with the sub issue.

Hi Kbarnes I really appreciate you doing this and all the others for your inputs so far too. As they say a picture speaks a thousand words. So voila! I present to you my pièce de résistance ahahah :
https://www.dropbox.com/s/fvweytg5q0...onnections.jpg


Hopefully this should help clear up how I've got things connected currently.

When I first ran the Audyssey, I had the mic face up and in the main location.

As for an unusual setup, I will take that as a compliment but yeah it hasn't been easy for me to get feedback when I need help

Edit: I am just going through the manual for the SA Amp again and I noticed this: https://www.dropbox.com/s/m0toy96qjcyj9c4/man1.jpg



Would this be the problem perhaps?

The other thing to think about is that you shouldn't be surprised the speaker crossover is set high when you are taking away their woofers! The 10" woofers are not "part of the speaker" as far as the receiver is concerned, as far as the receiver knows they are a separate subwoofer system so when it tests your FR/FL speakers all it is seeing is the tweeter and mid woofers. So a 110hz crossover seems perfectly reasonable in this circumstance.

Now that doesn't explain the high xover for the center, but I think that's likely an unrelated issue of room acoustics / placement (unless there is something else wacky about your setup we haven't uncovered yet ).

To me the only "problem" I see per se is that you have to turn the gain so high on the amp to get 75db output according to the receiver. Not sure what's going on with that but I might try to eliminate the amp itself as the offending variable.

I would not be worried that your woofers cannot handle it. I know the Gallo Reference 3.1 woofer quite well (I worked at the R&D site of the driver manufacturer) and if the 3.5s woofer is equally capable, it will provide plenty of SPL for most people, even for home theater use. Also, remember that you effectively have two subwoofers, which is a LOT better than just one.

Agreed.

If I remember correctly, Anthony Gallo used to cross over between the 4" mids and the 10" woofer at app. 200Hz, with a fairly wide overlap (i.e. not very steep slopes). So a 110Hz crossover suggestion from Audyssey would not surprise me at all, and I don't see any issue at all with using 110Hz or even 150Hz crossover, especially since the (sub)woofers are co-located with the front speakers, thus it will not pose any problem with regards to location of the bass. Only issue is that a small part of the stereo information will be removed, since the woofer signal is in mono.

On the gain.. Not so surprising, actually. The specifications on the 3.5s states 88dBSPL/1W/1m sensitivity, those speakers are power hungry and will need plenty of gain with most amps.

Hi jjazdk. Thanks for commenting. Man you really never know who you might bump into on the internet do you? I find it pretty cool that you somehow have some links to my speakers. Thanks for the reassurance.
I am definitely not dying for more bass that's for sure and with your comment there I don't think I need to be .

Only issue is that a small part of the stereo information will be removed, since the woofer signal is in mono.

On the gain.. Not so surprising, actually. The specifications on the 3.5s states 88dBSPL/1W/1m sensitivity, those speakers are power hungry and will need plenty of gain with most amps.
So from that I take it that:
1. Everything is a-ok? Just to clarify my front 3 speakers have their own amps. The woofers have the sa-amp and the back 2 are driven by the Denon. With that in mind, you reckon that it's unsurprising that I'd need to pretty much max out the SA Amp?
2. Secondly, I would like to confirm that if I can run Audyssey with a dual sub setup? Or should I revert back to one? This is just based on your input (about me having 2 subs) and another helpful post before saying that perhaps in Audyssey's mind, I've only got one.

Thanks heaps again everyone and batpig too!!

Many have noted that Audyssey can produce an overly bright soundfield, and that has been my issue as well. While the sound is crystal clear the highs are just a bit too overbearing - producing a ringing in my ears. I know this can be defeated but I think it will take a few adjustments.

I have had differing results with Audyssey - some results sound overly warm and even a bit dull, while others are very aggressively clear and high. The latter is more ideal, but I want it to have the clarity without the highs being so aggressive.

The success factor in getting clear sound has been measuring in the rectangular array both on and in front of the couch - per that diagram that's been passed around, and using the 8 measuring locations for XT. But it's crucial getting at least 1.5 feet of space between couch and mic. Otherwise I've had muddy sound.

The brightness could be because the mic is a few inches too high (as the L&R tweeters do fire right at my ear); it could be that the L & R speakers face straight out (meaning the treble is being boosted a bit to overcompensate for measurements in the middle area), or it's that the center is a bit higher and is not tilted downwards (I tend to think it sounds a bit better like this - but it could be causing a more "live" sound with the room). Or it's a combination.

If anyone has had success with setup procedure -- in getting clear sound w/ Audyssey that isn't treble-heavy -- please share.

Thank you
I used to have exactly the same problem with my Klipsch horn tweeters, too bright!!!


I always placed the mic exactly where the ears are, 5" away from the back of my seats.
When I moved the mic to 12" away from the back of the seat the warmth came back into the horns like a vengeance!
The speech now is absolutely superb, its just amazing to listen to with all that shrillness gone.
I'm over the moon with the warmth I have from the Klipsch horns which are often criticized for being bright.


In my case it was getting the mic away from the back of the seat, 12" for me is the magic spot.


Plus I do think getting the top of the mic inline with the tweeter for at least for the 1st position helps.
My tweeters are a bit higher than the ears for my most important row (middle) out of three. The 1st position I lift the mic to the tweeter height then drop it to the ear height for the other 7 measurements.


Experimentation is important, don't give up.

Hopefully this should help clear up how I've got things connected currently.

When I first ran the Audyssey, I had the mic face up and in the main location.

As for an unusual setup, I will take that as a compliment but yeah it hasn't been easy for me to get feedback when I need help

Edit: I am just going through the manual for the SA Amp again and I noticed this:
Would this be the problem perhaps?
Hi.

I looked at the images you posted, thanks. There seems to be no problem with the way you are set up. Incidentally, I would just use a Y-cord. As your 'subs' are, by definition, identical and equidistant from the MLP there's no advantage to be gained from Sub EQ HT's ability to set levels and distances separately. It makes for an easier setup for you.

I would also disable the XO in the SA amp - this is standard Audyssey advice and you will see it in the FAQ. Leave the XO to the AVR.

Given that you are set up correctly, the only remaining conclusion I can come to is that either the SA amp is not sufficiently powerful for the job (what is the power rating AAMOI?) or that it is not working correctly. It should be able to drive your subs to 75dB for the test tone at the start of Audyssey's cal.

So what are the consequences of just carrying in with an initial setting of 72dB? Well, your AVR sub trims will be higher by 3dB. So what are your final AVR trims? If they are still within a broad range of ±3.5dB then there is no problem, so long as they are not +3.5dB and you want to run them hot by 5dB and so on.

I don't feel that I have given you an entirely satisfactory answer, so if anyone else would care to chime in and add their own thoughts, it would perhaps be useful.

So first, I wanted to say this thread is awesome, and I've learned so much from the guide and the FAQ in this thread.

I have a question about where subwoofer gain and the crossover frequency should be set on the subwoofer when doing Audyssey calibration. But first, some background.

I have a TSC ASW-10 subwoofer.

I recently replaced my front three speakers with Wharfedale 10-series speakers (and will be replacing my surround speakers this week).

Audyssey 2EQ (upgrading soon) set the crossover frequency for my system to 120Hz, which sounds about right, given my old rear speakers are rated starting at 115Hz, so I assume it's calibrating to whatever the bottleneck is.

I'm currently trying to figure out what the on-subwoofer gain should be set at, as starting at the 50% volume mark, the subwoofer's trim was still -14.

My question is, however, with the above subwoofer and an Onkyo 507 receiver, should I set the crossover frequency knob on the subwoofer to the maximum frequency?

Also, would there be any benefit to using those high-level in terminals on this subwoofer with Wharfedale 10.1 speakers?

f)3. How do I set the controls on my subwoofer before running MultEQ?]

You mean the speaker level terminals? No.
