I can't even view your attachments. As a test; I just uploaded, and then deleted, a jpeg image using the insert image icon in the toolbar. Give that a try-- it worked for me.

Hey, it's good to welcome a fellow retired engineer and speaker designer. You will find good folks and a lot of good info here. I'm looking forward to seeing your system so post some pics in the Member's Systems section when you can. Enjoy the MLO Forum!

Yes. I think aesthetics is the priority for marketing purposes but their see-thru coating likely has more optimal (higher) resistance than a carbon black coating. Also, higher resistance limits charge migration across the surface, allowing the panel to operate closer to the ideal contant...

I don't know any specifics about JansZen panels so I can't answer that question. I believe that diaphragm coatings are the weak point in most ESLs so I will speculate that JansZen's longevity must result from using a very robust diaphragm coating. For example; Acoustat used an essentially...

I could be wrong but I seem to recall reading a post about ML committing to support their out-of-production speakers by building new replacement panels upon request. If so; one has to wonder whether those panels were sourced from ML.

Possibly someone on this forum has bypassed the passive crossover in a ML speaker but I haven't, and I don't want to speculate on which wires you would need to clip. All I can show you is a schematic of my DIY speaker (link below) which never had a passive crossover so its interface is minimal...

That makes sense then, as the diaphragm-to-stator spacing is closest over the spars, and charge tends to migrate to areas closest to a stator. Thanks for the info!

I had heard that a secondary graphite slurry coating was applied and you just confirmed it. Now I have a question: My one and only experience with ML panels was replacing the diaphragm in an older ML Theater panel. The diaphragm in that panel had a lighter coloration tint in the areas over the...

One other thought: I assume you cannot return the panel for a refund, so if re-inserting the wire doesn't work, then panel is dead. If this becomes the reality; then you have nothing to lose by reading my post below, and perhaps giving it a go...

Assuming you have AC power feeding in from the blue & black wires and DC power in the red wire, this leaves only two possibilities to explain why your panel still doesn't play: 1) The probe contacted the charge strip but the diaphragm coating is completely deteriorated and can no longer hold a...

Well there you have it Mr TheDoge; One who knows just informed us that the bias strip is graphite but the same solution applies. I think re-inserting the red wire as-is would probably not work so well-- but soldering it to a short copper probe, and inserting the probe to touch the graphite...

I'm using three stereo A/B amps (Carver TFM-25's) in a six channel stereo arrangement which includes two subs and an active crossover upstream of the amps. In this setup I have my hybrid ESLs being veritcally bi-amped, as shown in the block diagram below. I'm pretty happy with this arrangement.

I'm not sure our viewpoints actually conflict but they do differ in perspective. I would have to agree that an amp's total power probably would not be available to a single channel. On the other hand, unless each channel were fed by it's own transformer, or if the amp were in voltage...
