Currently I am using ML's SL3. Thinking of upgrading!! I will be eventually shifting to a city where 3 months in a year the weather is very humid about 90%. I have in mind either Maggies 3.6 R or Vantage. Which speakers have more longivity and protected against humidity? Speakers will be placed in a room which is 25' by 13' by 12'. Currecly my SL3s are about 6' from the front wall and 3 feet from the side wall. Listening position is about 12' from the front wall. Very nice imaging. Room is treated with Bass Busters and products from Room Tunes. Appreciate for a valuable advise.
