Tightening loudspeakers screws...

Mt.
I am not a pro and agree with Stringreen. I have had quite an experience with many loudspeakers and removing the grills is not always the obvious and best way to go; it depends on design,voicing and...set up. Regarding the screws I was expecting an answer on the torque issue but Cello is no longer available and I do not have the tool anyway...

I have received a professional the most answer from Matthew James Systems (they are servicing Cello and manufacturing new products with the same philosophy) and this kind of service is the one still building the brand even if it is not any longer in the market(!). They suggest to tighten up the screws every five years and do it by hand just to the point the screws will "tell" you to stop...and they certainly do it(!). Mt to you all and hope this to be useful for everybody.br.dgd
