    Close to a SL-3 but these are actually Sequel II's

    So what does disparity in panel life mean? I understand that the environment is a big factor, but that still doesn't seem to explain the poll results.

    My Sequel IIb's, which I bought new in 1993, still have their orginal panels and function fine. They do have a slight roll-off in the highs, but the room-correction system compensates, so even that's not a big deal.

    I believe this set will make it to 20 years before I need to replace them.

    My monoliths however, I believe their panels only lasted 14 years before I replaced them. Not because they failed, but they did have reduced output and roll-off.

    I think the Monoliths shorter life can be attributed to environment, I bought them used and they sat in sunlight in a bright room at the previous owners.

    They now sit in a windowless listening room with dedicated HVAC and HEPA filters. So I think it will be a long, long time before I worry about this set of panels.

    i'm one of the ones who voted at 19+ years. i'm just now looking at replacing my CLS. they've never been the "daily driver" i have quad-57 for that, but they do get their workouts. about 4 years ago they started to buzz and i pulled out the offending tape. since then they've been fine. but they are getting a bit "tired". restricted amounts of sunlight, no smoking, closed door to pets and respect all have helped.

    walk gently. leave a good impression.

    Hi,

    Would you explain "tired"? This thread and the disparity in panel lifetimes (aside from environment) has sparked my interest.

    Thanks

    Would you please explain the "respect" part - do you genuflect before them before each session ?

    I did say:

    "If you've saved your panels by washing them, or doing some other kind of renovation, how old were they when you did so?"

    So really, you tried to save them at 16 years, so that's were the vote should have been. No matter.

    they just don't have that pop or engagement that they used to have. the "presence" isn't there. although just before i packed them up i had a friend over and while her husband and I were listening so some piano tracks, she came around the corner and commented that she didn't know i had a piano, and then stopped when she saw it was the speakers. so they still have a good sense of realism to them.

    but to me, the punch just isn't there. so the midrange is starting to let go. so it's time to start thinking replacement when i unpack them.

    actually i did save them at 16. there is a difference between the life of panels that get washed and continue to live and panels that get washed and still experience dimished levels and there are lots of stories on both sides of the shower curtain.

    i read that statement to mean if you had tried to save them and failed. yep, i had the the tape go. but it was an easy fix that removed the problem. the panels had a problem and it was fixable, they hadn't yet failed and required replacement.

    no different (in my mind) than needing to upgrade the firmware in your blu-ray player. just regular maintenance.

    now, if i'd ripped out the tape and the panels had still buzzed - then i would say that the lifespan was 16 years. but i got 4 more out of them, and to some i still have more years left, but to me it's time.

    I've been meaning to raise this poll for a long time. Some real world data might even help ML, though I guess they have a pretty good picture of how long they really last from replacement panel orders.

    What this thread may do is give people a good idea of how long they really do last. From it, they ought to be able to ascertain whether they wish to make a purchase or not. A CLX or Summit X is an expensive speaker, after all, and some may consider essential panel replacement after a certain likely lifetime to be a major hindrance to actually buying a pair in the first place.

    Please don't let this thread de-generate into a Sanders life time warranty versus the lack thereof via ML argument. We've been there and made all the salient points already.

    Potentially a very interesting thread if life expectancy actually turns out to be much shorter (or even greater) than most expected. We'll see

    Multiple votes are allowed in case you've been through a few panels, but that only kinda works if they've lasted different time periods

    Additionally, please don't vote if you have simply damaged them by accident! Pretty obvious, really.
    So - if you haven't had an issue with your panels - then we do not vote? You are just looking for failures? As an example - I have had mine for about 5 years with no problems. How about a selection 'never had an issue w/panels'

    I think this thread is a pretty difficult one - in the sense that people's tolerance thresholds will vary. I couldn't live with one iota of a buzz. In fact, I know I'd replace them straight away if I heard that.

    My criterion would be:

    1) Any even mild disparity between left and right channel volume output.
    2) Obvious loss of HF output and/or loss of sparkle or general feeling of loss of balance between frequency extremes.
    3) Failure to pass a frequency response test I'd taken when new to within a reasonable threshold after any period of time.
    4) Aesthetic visual compromise arising from any cause.

    With my Ascent panels, I started to suspect/become convinced that the mylar coating applied by ML, which has a sort of distributed very thin black powder appearance (at least, circa 2001-2 and more so circa 2007), was starting to align itself with the stator perforations - literally a multitude of black dots Rather than depart, these molecules simply seemed to want to congregate and hang on.

    I'm not sure why I find this subject so interesting. Perhaps it is because I don't really understand it.

    What I find interesting is peoples acceptance of the loss of conductivity as a given, and little negativity towards ML's poor and inadequate application of the coating- all the other stat manufacturers have it sorted, why not ML?
    I just paid $900 for replacement panels so I feel the pain, but I'm also ****ed off.
