I am looking for a mic to record acoustic upright piano-not sure if I'm going to go with 1 or 2 mics (see my prior post of a couple of days ago for my setup). Have seen some good comments on this site for the AKG C1000s. I pulled down its specs. and its range is 50-20000. I'm wondering if the 50 is good enough for the bottom end of the piano. My prior Nakamichi mike (no longer working) had a bottom end of 30 within +/- 3.5 dB. The AKG frequency response chart looks like at 50 Hz the mic is + 6dB at a distance of 1 cm (.4") but its down 10 dB miced a little further back (distance unspecified in specs). On the piano the last octave is at 55 Hz and down. Anyone have experience with micing acoustic piano with a mic with a bottom end set of specs as described? Results?
