Topic: Technical specs for replicating physical piano
Hey guys! I know we have a forum of experienced individuals here, and I'm looking for a bit of advice on a pretty cool idea...
tl;dr: I want to modify a piano with speakers to make Pianoteq look and sound like a real piano, and have questions about the specs I'm looking for.
Pianoteq does a wonderful job of modeling physical properties of piano cabinets and room sizes for when listening in headphones, but what about simulating a true piano? I'm looking to modify an antique square grand piano by removing the key deck and put my midi controller inside (when disassembled it's the same dimensions) and remove the sound board and put in some speakers.
The goal is for listeners to experience an authentic piano sound from an authentic piano case, but with pianoteq inside.
Some presumptions about physical pianos to be taken into account:
It seems that pianos put out about 98 to 112 dB at the sound board
6 dB headroom would be nice.
The frequency range of a piano being about 28Hz to 60kHz, including harmonics and LF vibrations
It's unfair to expect headphone-like dynamic range from speakers, sure, but how close matters?
The speakers I'm looking at on the "PA" side of things:
QSC K8: 61Hz-20kHz, 127dB, $600
QSC K12: 48Hz-20kHz, 131dB, $850
Electro-Voice ZXA1-90: 48Hz-20kHz, 123dB, $600
The speakers I'm looking at on the "Studio Monitor" side of things:
Adam A8X: 38Hz-50kHz, 120dB, $1000
Adam A5X: 50Hz-50kHz, 110dB, $500
Dynaudio BM6A MkII: 40Hz-21kHz (@-3dB response), 119dB (pair), $750
So there's a huge difference in mentality between studio monitors and PAs with flatness of tone across the spectrum and directionality, but I'm not a sound engineer; I just want to avoid sounding like it's a recording of a piano rather than a real piano. I'd like to start bringing speakers home to test them, but knowing what to look for and what questions to ask would be immensely helpful.
Are my original presumptions about piano's sound anywhere close?
Should I completely disregard studio monitors for their inability to fill a room with sound?
Should I disregard PAs for their inability to replicate accurate sound?
Is it really possible within a budget of say $1500 to replicate the sound of a piano using speakers at all?
My interface is an mbox mini. Does that matter?
