Have been using a pair of RCF 912As for a couple of years. One of them seems to be on the blink - giving out a worrying hum but no output at a recent gig, so we had to do the gig on one speaker! Not ideal, but a couple of comments about being too loud at one point put my main worry about a lack of volume to rest!
I've got the possibility of picking up a used single 932A to replace the faulty 912A. Essentially same woofer, but better mid range coil which will be better for vox and guitar.
Bad idea to mix two speakers even when their specs are pretty close? Or will the overall impact be a slightly better mid range from the two PA speakers, despite the mixed mid-range 1" and 3" coils/horns and potential interference? I'm guessing the interference may not be too bad, given the greater directionality of the higher frequencies, and not something the audience at a given location will notice, whilst benefitting from the better vox?
Or should I just get a replacement 912A, instead?
