    inter - swop-ability of panels

    I don't know what model panels may be interchangeable but used panels are a gamble, and your query implies that you're handy enough to remove and replace a panel yourself, so restoring your existing panels may be an option. If the original diaphragms can be saved, merely recoating them (easy to...

    Restore dead panels for $100?

    Thanks Jonathan, I'm really curious to see if the string saw will work on larger panels without shredding the diaphragm. The Theater panel was small, having a short side-length tape line and only two spar bondlines to cut thru, which did not impose a huge drag on the string. I think the...

    Restore dead panels for $100?

    The prospect of having to replace a diaphragm is intimidating, even for a DIY'er-- but if you don't have to replace the diaphragms, a restoration is much simplified. I was amazed at how well and easily the string saw separated the stators. I have always used 6-micron diaphragms on my DIY...

    Restore dead panels for $100?

    This thread is for anyone with panels that lost output and shower cleaning didn't help. In this situation there's nothing left to lose so keep reading. I should stipulate that my only experience restoring ML panels was a single small Theater Center Channel rebuild, which may or may not be...

    System #525 (DIY ESL)

    My system is 6-chanel stereo and used for music only (I don't have a HT setup). RiPol's may not be the best choice for home theater sound effects because, being dipoles, they are less efficient than conventional mono-poles and they don't pressurize the room with energy that hits you in the...

    System #525 (DIY ESL)

    Since my last update I've replaced the RiPol subs yet again, with a third version which are even more compact (1/2" less height & depth). I also angled the wood grain directions for aesthetics. A RiPol has a cardioid radiation pattern which tends to not excite the room's resonance, but it's...

    Favorite YouTube Channels?

    After this girl gained such notoriety on Youtube, other hot Asian girls started posting their own repair videos, except wearing really skimpy shorts and flashing crotch shots. Just do a search for "genius girl mechanic" and check it out.... obviously, they figured out how to monetize their...

    Martin Logan ESL X three strips don’t emit sound at all

    That's an idea worth trying. Perhaps I can add to it: It's helpful to understand how the panel is constructed. On the older ML Theater panel (the only ML panel I've seen disassembled), the diaphragm's conductive coating was not continuous but applied to each cell individually, and only in the...

    ESL-X sound faded in the middle of the panel

    Sorry to hear about your misfortune. I'm afraid your only remaining options are replacing or rebuilding the panels (yeah, both... you wouldn't want to do just one). Russ Knotts at ESL Repair.com can rebuild those panels for you at a reasonable cost, and he does good work but he's often backed...

    What causes panels to wear out?

    Just curious which Eminence woofer is in your speaker. My hybrid ESL has an Eminence Kappa-Lite 3012LF (12") woofer under the stat panel, which is a pro-type woofer that's optimized for a ported cabinet, but I have it mounted on a modified H open baffle (the triangular side-legs of my speaker...

    What causes panels to wear out?

    I'm not familiar with ML models and specs (not a ML owner) but I think 180Hz is too low to set the crossover on any hybrid ESL panel that's than less than about 20" wide (panel + baffle). If your panel is significantly narrower, it's mid-bass output will be rather thin/anemic if crossed over at...

    Martin Logan Shower Cleaning PDF

    If the diaphragm coating is still good (still electrically conductive) but its electrical charge is being drained away (faster than the HV bias supply can replenish it) by contaminants creating shorting paths to a stator, the panel's volume will be diminished. Particulate matter (dust or...

    What causes panels to wear out?

    Not to worry... even with the added D/A & A/D conversions, once you've experienced active bi-amping, you will NEVER go back to a passive setup. The only stipulation is that the DSP must have EQ capability because any tuning filters (notch or shelving filters) in the passive crossover to...

    Sequal MK 1 Vs Vista

    It's been my experience that panel size and transformers are the significant variables affecting an ESL's sound, and [transformers being equivalent], bigger panels sound better.
