Will be updating this as we move along building one of each. Each one will be relatively fresh with ~5 minutes of break-in time playing low frequencies on our bench 1500D. Amount of break-in between coil configurations isn't necessarily identical -- check CMS, a lower number indicates the suspension is still tighter. Stock 3 Hard Spider Suspension on each model with "daily" stock coils. Measured with Woofer Tester II unit ---------- 10" D2: RE: 3.92 ohms Fs: 50.9 Hz Qes: 0.51 Qms: 12.72 Qts: 0.4
