Thanks Scott, I appreciate the advice. I'll unplug them tonight and try that out tomorrow. BTW.. My name is Scott also

Nice to meet you!


I do mine anytime I have the shop vac down there to really clean well around the equipment and cables.

I'll see/hear them in Chicago. 'Hear' is sort of a relative term given that the noise floor of the room will probably be something like 70db. At least I'll get to see everyone that I haven't seen for about 10 or 15 years.

What's the 15A? I cleaned my speakers with compressed air and a microfiber cloth. They looked pretty clean already. I swapped left to right and its still the same. The speaker just doesn't sound as clear as the other one. Also, I noticed when I plugged in the good speaker the blue light came on right away, the other speaker it doesn't,but it does come on when you start playing music ect.. Weird..

I don't think either of mine do until I start playing music

"I swapped left to right and its still the same"

You swapped speakers or panels? "Still the same" meaning the problem moved to the other side?

I would also swap the power supplies from side to side, they are usually the first thing to go.

IME when the power supplies go it's usually the filter caps and they add some hum, not sure I've seen them reduce amplitude without some other symptom. It's possible the signal (coupling) transformer has gone bad, however.

And filter caps generally don't go if the product is used on a regular basis. I understand that if it sits for ten years or so.

Well, electrolytics do eventually dry out. The spec on a typical electrolytic supply cap is something like +20/-50 % tolerance to allow for aging. High temp makes it worse. Other types of capacitors are more resistant (different electrolyte, construction, and most other types are sealed) but all will eventually wear out whether used or not.

However, electrolytic capacitors that have been sitting for a long time should be reconditioned before use, which usually means a high-value resistor to limit inrush current and a variac or other means of bringing the voltage up slowly. They will decay over time even when not in use, but a stored capacitor (techie pun) will often be just fine once conditioned. Powering a 10 or 30 year old supply up cold without any current and/or voltage limiting will likely cause capacitors (among other things) to fail.

Martin Logan's new 30K speakers. Very interested as they have 2 12" built in subs should sound awesome.

I saw those.. When someone called them 15A .. it just threw me off. Also.. I ran audyssey Xt32 last night, as usual the culprit speaker is always +2.. Weird..

I started building out my media room and went with a Motion 30 center channel, 6 Motion 15's, and 2 HSU VTF-15H's with a Denon AVR-X3200W. I put a old set of towers from Polk, but you can definitely tell they can't compete with the ML's. I am thinking about getting a pair of the ML 60XT's. However, I am curious what the thoughts are on if the 30 will keep up with the 60XT's and also do I really need the towers? Is the ML Motion 40 towers a better option? Any help is greatly appreciated. Thank you.

I started with 60XT's paired with a 30 center and 15 surrounds. After a few weeks, I ended up exchanging the 30 for a 50XT and the 15's for 35XT's. In my mind the 50XT sounds much more balanced and full with the 60XT's. For the 35XT surrounds, I cannot be sure. They definitely sound good but I am not sure if it was a great improvement or just my OCD kicking in. LOL.

I am pretty happy with the sound the way it is. Are the towers worth it? If so, it sounds like either trade up or go with the 40's? Thanks for replying.

I listen to a lot of 2.0 channel music via "pure analog" mode through my AVR and felt the better bass response of the 60XT's was worth the price difference with my subs disabled. For movies and other sources using the DSP and my subs, the 40's would have been adequate for my enjoyment. My previous Polk's were all 1983 - 1985 vintage so any of the ML's were surely an improvement. LOL.

I swapped the power connectors and still the same issue. Left speaker(the culprit) was +8 and the right was +5. Any other suggestions?

I just realized I typed that wrong. I have a AVR-X6200W. I don't know if that makes a difference or not other than going to 9.2 and the increased power"? This is all good information. Thank you very much.

I think the warranty on those are five years. I think it's getting to be time to making the call.

I tried to call Martin Logan 4 times today, no answer. I resorted to using their support e-mail. I've only had these for 3 years, so I'm a little disappointed.. Shipping it out is going to be a pain in the A*s..

It won't be the entire speaker. It will be just panel return. They'll run you through some diagnostics to figure out what it is. They'll send you a replacement panel and then you'll use that box to return the old one.

I think that speaker is getting worse. The right was is still at +3 and I had to bump the Left one to +11. It definitely sounds different. The left one sounds muffled compared to the right..

Could be panel, could be the transformer or power supply. Agree with Scott; definitely contact your dealer and/or ML service.

I tried to call them 4 times yesterday, no answer. I emailed them on their support page. Hopefully they get to me soon. I was wondering why music sounded so one sided. I realize this has been going on for about 2 months and didn't realize what was going on til the other day.. Grrrrr!

I have a pair of Martin Logan Source ESL speakers that are 5 years old, and I have been very happy with them. I love listening to them and I have gotten my money's worth over the years. I use them as my front speakers in my audio room. 99% of my listening is music, with a movie occasionally (not very often).

I recently updated my system with a new McIntosh 6700 Receiver / Amp and it has done wonders to improve the musical experience in the room. I listen to music at least an hour, almost every day of the week.

The only shortcoming to my setup is - I have a very narrow sweet spot of perfect imaging. The sound quality when sitting in my seat is perfect, but if I sit in adjacent seat there is and obvious dramatic drop-off in imaging quality. My room size is 13' wide X 15' long X 9.5' ceiling height.

I have played with my speaker location, and am wondering:
1. Should I pull them out from rear wall even more than I currently have them?
2. If I do this, can I reduce the toe-in that I am using and will that widen the sweet spot (or will it only increase bass)?


With my recent upgrade to the new McIntosh 6700 I am actually considering a significant upgrade in speakers (since I listen to them so much now). If I can make big improvements to above I will consider keeping them longer, since the music is acceptable in my chair. I have listened to many speakers and am considering a pair of B&W 802 D2's. (greatly discounted floor models)

I am hoping to hear feedback from other experienced users on obvious changes to physical location of my existing front speakers.


Thanks!

They look pretty close together. The closer together ,the narrower the sweet spot. How far from the speakers do you sit. Personally, if you have the money to thrown down on a McIntosh receiver, I'd definitely upgrade the speakers also. I'd go speaker shopping and listen to what's out there. That room might not be the best for electrostats. If you love the electrostat sound, get the EM ESL's which are a big upgrade over the source's. I'd have those speakers firing straight ahead with no toe in. They are just too close together. The 802 D2's might work better. I'm assuming they are book shelf speakers. Add a sub and you would probably be happy. I'd personally just buy them, listen to them at home and if I didn't like them, take them back.
