I've recently purchased an Apex 210 ribbon mic that looks very similar to the Nady. The grille is shaped differently, and the yoke has radiused corners rather than the 45 degree corners. The can that the cable runs into looks identical.
This product came out a couple of months before the Nady, but the description and appearance are similar. Probably from the same factory.
Common specs:
long element ribbon mic
30 to 18000 Hz
165 dB Max. SPL for 1% THD @ 1kHz
The Apex also comes with a well made vertical aluminum flight case to prevent the ribbon from sagging when in storage.
I'm thinking the SPL spec is, uh, a bit optomistic...
If you remove the can from the bottom of the mic, you can see that it has a coarse wire mesh grille on the outside, a fine wire mesh grille behind that, a silk sock behind that, and a series of metal plates with larger holes drilled in them, and what looks like metal pop filter screens attached before you get anywhere near the ribbon. It's a huge mic that weighs almost as much as a Gibson Les Paul. Almost. I'm thinking all of these screens are what contribute to the overblown SPL rating.
I still haven't used it much, but it sounds very good. Unfortunately, I don't have any other ribbon mics to compare it to. Considering I can get 2 of these for less money than an Oktava ML 52, plus the case is heavy duty, I'm happy.
It'd be nice to read about comparisons of these Chineese mics to other wlad to seeell known ribbon mics.
