Hi,
I have just bought a pair of 2420 to try(instead of my old Altec 808-8A) with my small 1kHz LeCleach-horns to be used from ca 4Hz and up. Below that I have a pair of 200Hz LeCleach together with 2440. No problems with these as they are biamped.
I was thinking of using 2405 with a passive simple filter from where the 2420 rolls off. But before I buy a pair of the premier I have to know the real life sensitivity of both. Will not dampen the 2420. Have anyone measured the two separately or together?
