In Reply to: Low eff. mass arms are not a good match with Grado wood bodies. posted by Rick W on July 24, 2014 at 08:19:51:
Regarding arm mass and Grado cartridges, this is the e-mail I got from Grado: "it not about the mass but about the resonance of the system
to calculate the resonance of the system
use the following formula:
Resonance Frequency= A divided by the square root of M x C
A =159
M= mass of the tonearm and cartridge,
C = compliance
Mass of a Grado cartridge is 6 grams...add to mass of tonearm
Compliance of a Grado cartridge is 20
ideal RF is between 8-12 hz
let us know if you should have any questions... end"
It's a little funny to me that they say it's not about the mass, as the only unknown in their equation is the mass of the tonearm. I ran the numbers and get the Statement Sonata should be good with a tonearm effective mass of between 3 and 13. Definitely well into low mass territory at the lower end of the range.
