Posted By: bilgirami M-60s have turned muddy - 12/13/09 02:38 AM
Guys, havent been on the forum for a while. Hope all Axiomites are doing well and getting ready for the holidays

The reason for this post is the at I have run into a bit of a situation. I purchased my M-60 VaSallo series about a year and a half or so ago. Loved the way they sounded. I used them for about 7-8 months and then ended up putting them back in the box (with the bag and packing and everything) as I was moving. We moved but the speakers stayed in the box for another 8-9 months as I started work on my basement in the new house. Finally the basement was ready and it was time for the Axioms to come out of the boxes again. During this time, I have also replaced my RX-V663 with an 863 (needed an extra HDMI). I hooked it all up this evening but was shocked to hear what the M-60s were sounding like. They are not half as clear and clean as they were 8 months ago. For a moment I thought the issue might be with my new receiver. I have a pair of bookshelf Paradigms. I took the M-60s out and hooked up the Paradigms. They sound as expected. No issues. The clarity and crispness I am used to getting from the M-60s is just not there. I am not sure what could have happened to my M-60s. Many folks would know that the RX-V863 has a 'pure direct' option too. That too did not help. If wiring was an issue, the paradigms should sound funny too. I have banana plugs at both ends, so when I take M-60s out and hook paradigms up, I am actually pulling the banana plugs from the back of my M-60s and sticking them into the bookshelves. Can anybody think of anything that could have happened. I have checked and all drivers are working..

Thanks folks.

Are the gold clips between the terminals on the back of the speaker securely in place and are all terminals tight. Is it both m60's, or just one?

I agree with siquack, check that the gold clips are secure. If they are, remove them and connect only to the top set of inputs, test, then try the lower set. If one set produces no output, there may be a bad connection inside.

On mine, the lower connection was broken inside. I didn't notice at first because audyssey configured the subwoofer compensate. But it didn't sound quite right and not very good with audyssey disabled/no eq. I thought it was odd that it set the the subwoofer crossover so high at 150Hz. I fixed the bad solder connection inside (suspect damage during shipping), audyssey set them to "full band" and subwoofer off. And now sounds amazing with audyssey on or off.

Syed, although you say that you've checked and all speakers are working, I still question it. In the moving and storage process there were certainly chances for something to come loose, and your description of the sound would be consistent with one or more drivers not working. As was said, double check for the tightness of the connecting strips on the terminals. Connect the speaker wires to the top(mid and tweeter)terminals if they're now connected to the bottom ones. Does the problem affect both M60s equally? If none of the forgoing is helpful, can you open them up to check for a loose internal wire?

Umm, yah, you moved.
New room, new acoustics.
I highly doubt anything is wrong with your speakers as it seems you've checked for loose wires and such.
Assuming the Paradigms still sound the same in a different room while the M60s sound different could easily be a psychological perception.
Audio memory is incredibly short.

We moved to a new home from our old place. The Axioms sounded great on our main floor. The main floor we have now doesn't sound good for anything i've put there.
Lesson learned.
Rooms make up a huge percent of the audio difference.

Sounds to me like the new placement of the speakers is affecting the sound quality. Don't forget that your M60s are ported front and rear so placement can make a big difference. How far away from walls and other furniture are they? Even giving the rear ports an extra 4 or 6 inches to breath may affect the quality of sound. Are they close to side walls or in a corner? Try moving them around a bit. I'm guessing your Paradigm bookshelves are not ported.

I saw that the receiver you had and now have has the "YPAO Automatic System Calibration" feature which appears similar to audyssey. I would try re-calibrating your system to your new room with it, and compare the settings to your old room (did you write them down?). This would give you an idea of how different the new room may be. The Paradigms, although similar to the M-60s, may be more forgiving.

Folks, thanks for the suggestions. Here is where I am at right now. I rechecked and all drivers are working. old clips are securel in place. The issue seems to be with both M60s. Did not get a chance to take a take the gold clips off but I will try to do that tomorrow. My front right is in a corner but it is about 6-8 inches away from the wall on the side and abtleast 8-10 inches from the back. I dont think the issue is with the woofer. If anything it is the midrange. Music is just not clear and crisp. The issue is just a little less obvious with movies but slight attention to detail tells me the speakers arent doing their bit. I will recalibrate them over the next couple of days but if that doesnt work, I may have to call Axiom to see what they think?

You'll notice this if it's the case from the good advice above, but I too had this issue when I somehow accidentally turned on my Denon's EQ feature and it got set to "Flat". Sounded awful for a couple of days until I tracked it down.

It's is the room. It is not surprising. Try moving the speakers further away from side and back wall to increase the delay in the first order reflection. That helped the clarity in my setup when I moved to the HT.

Do you have any room treatments, or is this an empty in-progress room? An empty room will sound much different. Is the square footage the same as your old room? If there is much more air to move, you might have found the limits of the M60 or the AVR in your set up.

Does not sound like a speaker problem, just a room issue anyone that has moved will be familiar with.

+1.

The interactions between the speakers, the listener and the room play a huge part in perceived quality.

Would this problem not exist with his other speakers, assuming he placed them in the same location? He did mention the other speakers sound fine..
Posted By: Adrian Re: M-60s have turned muddy - 12/15/09 01:47 AM
The other speakers were bookshelfs weren't they? maybe not so placement-finicky.
Posted By: Micah Re: M-60s have turned muddy - 12/15/09 03:05 AM
Move back. Problem solved.

Well, larger range of frequencies should equal more chance for nasty reflections and nulls. But I agree, if really checked at the same spl and same source, you would not expect the book shelves to sound great and the 60s like crap. I was thinking that "evaluation" was of a rather non-critical variety, but that is an assumption on my part.

It definately sounds to me like gremlins have a hand in this somewhere!
Posted By: bilgirami Re: M-60s have turned muddy - 12/20/09 02:50 AM
Folks, tried it all. Not sure what it is. The speakers are placed on a carpet, so i thought maybe that have something to do with it. I installed the rubber feet that were not there before. Did the sound improve, hmm, yeahhhh, maybeee. I will probably contact Axiom now. These are still under warranty so, if it takes it, i wont mind sending them back to Axiom to see what they have to say about the sound quality when they test the speakers out with their setup. Thanks for all the suggestions.

Could try them in another room before shipping those big hunkers? I had a bad shipping experience when I sold my M60s.
Posted By: Micah Re: M-60s have turned muddy - 12/20/09 05:12 AM
There's an idea. If the room you have them in now is drastically different from the room they were in over in your previous home, is there a room in your new digs that is fairly similar to your old room? If so, perhaps putting them in that room and giving them a listen will tell you if it's the room dynamics at play (as many here are suspecting it is) that are fouling your listening experience.

Just a thought.
Posted By: SirQuack Re: M-60s have turned muddy - 12/20/09 04:32 PM
It does make sense that both speakers are doing this, must be the room or receiver or using. When these were not being used, how and where did you have them stored?
Posted By: Adrian Re: M-60s have turned muddy - 12/21/09 03:02 AM
Randy, I was wondering about the storage thing too.
