When I read this tread I am getting more and more concerned. And there are 3 main areas of my concerns: 1. all this deal with potential lethal voltages so whatever you do it is good to have at least understanding of how it works and what you do. 2. DC blocker - as name suggest - may help to...

My 3c to this. Big transformers (like those in big power amps) sometimes are prone to DC in mains and effect of this is hum which is result of phisical vibration of transformer core. And in this situation DC blocker may help. Taking about ML speakers there are 2 types of transformers: one in...

Thanks Neil, that is a good news! So maybe next time (if I will have to do this again) I will consider this coating. As of now I have a very positive effects with MJ Dijkstra coating - very stable 10e9 and my MLs sound again like a charm!

Hi, How this new coating is doing? My Lycron coating died after around 1 year and I am looking for a new ideas...

Detaching panel from bass unit is definitely not intended for end-users therefore I am not surprised that you can not find this procedure in User Manual. But it doesn't mean it is not doable... Assuming that Summit X are similar to Summit - you will have to remove bass unit top cover and then...

Hi Neil, So what spar thickness you have finally for front and back stators? Also, what arrangement you have around copper charging strip? I can see 2 possibilities here: - spray coating on the foil with no copper strip and then glue strip over the coating surface (this requires that copper...

Entire active bass section of Summits is located in the back 'compartment' so there is no need to remove front grill/front woofer. And removal of this amp plate is easy - just few screws. Once removed you will see 2 ICE power amps stacked on the top of active bass EQ board. BTW - in the front...

Unfortunately entire panel (upper part) and woofer grill is one assembly piece being holded together by side bars. You may try to get this screw following roberto advice by unscrew lower brackets (3 screws) and very gently tilting entire panel to gave enough opening just to remove this loosen...

Hi, Thanks for your reply. I was struggling a bit with proper thickness of spars for my Summits. When I measured thickness of original spars I recovered from my panels I got 0.8mm for rear and only 0.2mm for front. This is thickness of plastic 'core' of the spars, completely cleaned from any...

neil5m, Just wondering - as per above your orginal spars were 0.6mm (rear) and 0.2mm front and finally you used spars with more thickness (front spar 0.2mm -> 0.6mm). What is the reason for this? As this triples stator-membrane distance I would expect some audible effect resulting in lower SPL...
