Russknotts@ gmail.comI know this has been covered many times. But who is is that refurbishes panels?
Did your new panels in 2006 change sound, improve after being used for some time? Was there virtually no change after "breaking them in"? Im curious.Do panels age? Very good question. I got new ones for my Monolith IIIs back in 2006 along with new power supplies and I'm using a Krell KBX balanced crossover. I had a problem with my system's sound and was 100% certain that it was due to my panels. So, I ordered new ones early this year. It turned out that it wasn't the speakers that was the problem at all. So, I have new panels that I am storing also.
Like Robert, I also changed my Monolith panels in 2006 (see: Monolith refresh - Panels, woofers and rail stain updates )Did your new panels in 2006 change sound, improve after being used for some time? Was there virtually no change after "breaking them in"? Im curious.
Yeah, 28 years is good. I dont know how the previous owner had his Prodigies placed, except that when I picked them up from his house they were in a room with a lot of sunlight. They are 20 years old now and just seemed to have lost volume mostly. Without the Audyssey on the woofers overpowered the panels. Apparently the audyssey must tone down the bass since the panels were down in volume because they sounded balance with it turned on. So mine being 20 years old seems they needed work.Like Robert, I also changed my Monolith panels in 2006 (see: Monolith refresh - Panels, woofers and rail stain updates )
And after 14+ years, they still sound excellent. But they are in a bat-cave dedicated room and I have OCD around vacuuming and air-quality (Hepa filter runs for a few hours every night in the room), humidity is controlled by HVAC.
Measurements seem to be about the same as year after installation, so they remain consistent.
For me, there was a noticeable "break-in" period of about a month, but happening mostly in the first week. The lower end improved IIRC.
I wound up re-doing the room correction a couple of times in the first six months as I was tweaking the rig a lot around the also new SL3XC center speaker I built.
Since we are on the subject of old vs new panels, my rear Sequel IIb I bought new in 1993, are still on their original panels. Measuring, they sag pretty heavily on the top-end, but it just happens to align with the Audyssey target curve, so all good.
Maybe next year, I'll buy replacements for them. So a 28 year life-span is not bad.
Well, Russ was ready to begin work on them but gave me a call yesterday. Apparently on some Prodigy panels ML used double sided tape going horizontally across the mylar, all through the entire panel. The older MLs didnt have the adhesive all the way across. He said that it would be extremely difficult to separate the stator panels because of this and he couldnt guarantee that the mylar would not rip. He can repair the rip but it wouldnt be like new.Robert, please let us know when you get the panels back how they sound!
He told me that he can usually get them to about 90 to 95% the same db level. Overall sound is going to be subjective. He did tell me that they sound a little less analytical and warmer. He compared them to sounding similar to Quads.Thank you!..... I've been waiting to hear an honest assessment of Russ's panels. No slight to Russ, but I somewhat suspected that his special re-coating is not only darker (in color) than M-L's, but it's thicker maybe, and therefore sounds different than the original diaphragm? I've been wanting to rebuild my SL3's. Washing the panels helped a lot.... They are listenable now, but I'm looking for true restoration, so I think i'll pull the trigger on new panels from M-L.
LOL! Ive got a Porsche 911 turbo that is just sitting in the garage, i dont even drive it now since the covid hit. I miss my Martin Logans!!!Looks like they will be busy over at ML -I have a pair of CLS panels on order too.
ML withdrawal - it's like that car "...there is no substitute"
