A while ago I got a pair of Wharfedale Dovedale 3 but unfortunetely had a tweeter fail, the dome material cracked and the tweeter sound crackly and awful... So I set about finding a replacement, but this is the most information I could find on my speakers. Given it doesn't seem to show any 1w 1m SPL level other than "Zero level" I decided to go with a pair of tweeters rated at a SPL of 90DB (Monacor DT-140's) given I feel that these Dovedales are pretty efficient. It was recently suggested to me that the Dovedales have a SPL rating of 84DB since 14 + 70 = 84DB, no idea how he came to this conclusion but I'm considering building a L-Pad to bring these tweeters down to a SPL of 84DB but using my amplifiers tone controls, turnover at 5KHz which is the crossover point of the tweeter and mid range and set the tone control at -3 which should give me about a 6DB drop, doing this made the speakers sound kinda lacking in high end. So I was wondering if anyone had any advice for me as to finding what the SPL of my speakers is.
