ok, these things suck
I bought 4 of these from 8th street..they all sound different, totally...I mic'd up a Yamaha NSa-636 playing Bon Jovi's It's my life from about 4 feet away, all of them pointed at the woofer, along with an AKG C3000b, just for kicks..
#1 - upper mids are very accented, highs are fairly sibilant
#2 - highs are kinda tinny, better than #1 overall
#3 - bass is less prominent than both 1/2, mids/highs are better
#4 - highs are somewhat harsh..best of all 4
C3000b - everything sounds more natural, no real harshness.
in comparison, the 8000's sound kinda gross compared to the AKG, just like something is 'wrong', but can't really put a finger on it.
But for $35 a piece, I could rig one up in the studio for a constant talkback mic..but forget about doing any stereo recording where consistency matters..they might sound decent on individual instruments, but it would be the last mic I'd go for..I think I'd go for an SM57 first.
I'll write more when I test them further, but so far, I'm underwhelmed.
