Just got my SP newsletter:
Though we've established a reputation for delivering great sounding microphones at a reasonable price, we really haven't made many changes since we first introduced the C Series designs in 1999 and the B Series in 2002.
Engineered from the "ground up" to deliver superior performance, our new microphone product line will not only deliver the goods, but deliver them in style!
As you can see, all the mics have received a "face lift", a sleek new look that belies the price point. The physical changes aren't just cosmetic. We've improved the headstock by using a wider, heavier mesh that is not only more sturdy, but is less acoustically intrusive.
Then look under the hood, and you'll find changes there as well. We've updated the capsules and electronics to deliver improved sonic characteristics, greater dynamic range and lower noise (though they were already pretty darn quiet).
Additionally, we've added features on some models such as 75Hz and 150Hz High Pass Filters and - 10dB and -20dB Pads. The C3 now has 27 possible variations of settings!
