Its a Lab Gruppen amp design and the Sanway FP14000 copy is damn close in specs. If you try again you'll be able to discover just how face-meltingly awesome the FP14k is. We'd all pay for real Lab Gruppen amps if we could, but since we don't make money off our systems Sanway copies are a Godsend.
cms, aka driver diaphragm suspension mechanical compliance: 0.000065 meter/Newton or in standard form 6.5e-05 m/N. (smaller number is better)
rms, aka driver diaphragm suspension mechanical resistance: 6.41 Newton.sec/meter. (higher number is better)
