QUAD 2905 . humidity and reliability

I always seemed to have some issues with electrostatics over time even in an environment with low humidity. I would eventually hear some rattling from the panel on certain frequencies. This has happened on Quad 63's, Logans, Acoustats, etc. After a while, I would listen for the rattle instead of enjoying the music. Based on reading various reviews over the years (since the 70's), I was led to believe that Electrostatic panels were the way to go sonically. However, I have learned over the years not to take too much stock in what you read. To my (experienced)ears, great dynamic speakers sound much more real than great Electrostatics, with far more reliability. I will say however that Maggies seem to be very reliable, the problem being their overall sound.

How can anyone answer your reliability question? They haven't been around for 5 years.

The QUADS were designed in England! You don't get a much more humid enviroment than that! QUADs of all vintages are usually good for 20 years if not abused. My friend repairs them and has done both 63's and ESL57's.

Hi there

Which country are you in? Here Singapore, humidity runs at around 85%-90%. It is not kind to electrostatics. Martin Logans are especially susceptible, as the panels are exposed. Quads and Acoustats seem to be a little more resilient, due to the dust-covers I suppose.

Running Martin Logans here means you have to be prepared to change panels once a year. Even the sound changes depending on the humidity levels. They sound better when humidity is low, and become rolled off as humidity rises.

I love 'stats but I would never buy another pair unless I moved to another country with a dryer climate.

Another no-no for humid places is drivers with foam surrounds. They rot and crumble after 4-5 years. Even sneakers and sports shoes suffer the same fate!

Kind Regards
