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...

Any DIY'er would love this genius girl mechanic. She has a huge following on Youtube. Whether it's repairing farm equipment, carpentry, welding, rebuilding diesel engines or rewiring electric motors; this girl does it all, and she's really cute too:

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...

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...

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...

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...

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...

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...

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.

Never mind... I just saw your other posts about your Clarity speakers outputting no sound.

Hi wfissel, What problems are you having with your Clarity speakers?

The heat-shrink method isn't the best choice for curved panels because it tensions the diaphragm equally in all directions, whereas a curved panel should be tensioned predominantly lengthwise, with only enough widthwise tension to pull out any wrinkles (tension across the curve tends to pull the...

I can tell you how my MkIII speakers diaphragms are tensioned but it would not be applicable to an ML panel, because my panel configuration is so different. I tension my speaker's 6-micron Mylar diaphragm to 1% -1.25% elongation (verified with a simple scale measurement), which results in a...

Welcome to the ML Forum, Probe! I guess you're discovering how addictive ESLs can be :-) BTW; I have a Carver C1 and three Carver TFM-25 amps driving my system, and the Carvers still sound sweet. Charlie

Good stuff John, Most Acoustats were full range ESLs, which need about twice the diaphragm-to-stator gap (d/s) to accommodate the greater excursion for bass, so the bias voltage had to be at least 5kV to keep the efficiency up. The breakdown voltage of air is about 100V per mil, and a good...

I believe that ML added the music sensing circuit to mitigate the panel fading problem by de-energizing the HV bias supply when no music signal is detected. Whereas on earlier models the bias supply remained energized 24/7 (whenever its AC power cord was plugged into a wall outlet). If so...

Assuming the problem is within the panels (not up-stream); Panels lose volume when their diaphragms can no longer hold a full charge. These conditions can cause a panel to lose charge: 1) Contaminants creating shorting paths to the stators and draining away charge, in which case shower...

The diagnostics JonFo referenced above should nail down the problem but I will venture a guess that's consistent with the symptoms. I think it's probable that both panels have lost volume due to degraded diaphragm coatings, and that may be the extent of the problem. However, when panels...

Welcome to the forum Fulham Tarheel, Nice score on the ESL9's, and no need to apologize for Class D. I remember the early class D offerings were only for subs plate amps. They were cheap but prone to self-destructing but they've come a long way in recent years. A friend of mine recently...
