    • The coils were matt after 4 years, at least on the surface. However, current only flows on the surfaces of a coil. You would have to measure how and whether the current flow from an untreated to a treated coil changes. However, my focus is now to deal intensively with the new external crossover for the Rf7 MK II. The new, wider and deeper housings are already in the works, I think they will be completed in a good 14 days.
    • Just something to think about. White vinegar is acidic and undiluted has a ph of about 2.5. I use straight vinegar to acid wash my tankless water heater piping. Once you apply vinegar to the driver cone and its surround some will be absorbed into the material and cannot be removed unless you flush it. It would have to be copiously flushed away or neutrilized with a base.   My recommendation: brush away as much debris as you can with a brush. Then if you feel the need, brush it/wash with straight water. Once you are done, the water will dry off leaving no acid behind. Put it in the sun to dry. A water wash and brushing will remove 98% of the debris, stains are not going to hurt anything, or impede its performance. No water anywhere other than the cone face or surround. No water on the back side or spider or motor mechanism.   Absorbed acid in a porous material (paper based transducer cone) long term.....not a good idea imo. Just asking for trouble. (I did work as a lab tech many years ago)   ph of vinegar: https://www.healthline.com/health/ph-of-vinegar
    • I would think most ss equipment would have a low enough output z, but you would really have trouble with a lot of tube gear. Given your setup,  the worst case for you would be the bass roll off.
    • The above article also mentions the double compression effect: compressed source file compressed again by bluetooth transmission. Not a good mix for true hi fidelity. 
    • From what I've been reading, vinegar penetrates very well and will kill off the mold at its roots. Use white vinegar, undiluted.
    • I'll be there to help all those that need it.
    • Actually, my personal experiences with Khorns in such low ceiling small rooms have not been good.  Of course, nothing that I've heard in such listening spaces really sounds very good.  The Khorns sound pretty unnatural, tonally unbalanced, and harsh to my ears in that kind of room, even if treated acoustically, even if tri-amped and time aligned.  The midrange horn in the Khorn (K-400) is the problem.  It puts too much acoustic energy on the floor and ceiling below 2 kHz.    I would replace the K-400s horns/drivers and the tweeters to full-range horns/drivers having taller mouth sizes or use something like an air motion transformer (AMT) that can extend its SPL response down to 400 Hz or lower, which have very narrow vertical coverage angles.  The stacked/winged ESS AMT-1 approach is the type of AMT assembly that I'm currently considering, but either approach really requires a DSP crossover (bi-amping or tri-amping) to integrate with the bass bins.    There is an alternative approach: build false corners for the Khorns and put them in a much larger higher ceiling room upstairs.   Good luck.   Chris
    • How big is the room and what source are you hearing the issue?   Also, I agree, more clarification on “sound goes out”.    I ask about the source as I have noticed that my speakers make a crackling sound,  aka “breaking up”, when I am listening at higher volume via Xfinity HD.   Same speakers, same settings at same volume, using a 4K Blu-ray Disc on my 4K Blu-ray player, I achieve crystal clear audio at any volume I could ever withstand.   What source are you experiencing the issue, or does it persist across all sources?
