This is a pair of 12-inch midbass 95db woofer by Italian firm 18 Sound in original box. Model is 12NDA520 with AIC or positive feedback to lower driver impedance. Neodymium magnet. 1 woofer is new never used. 1 woofer is used once or twice. I bought 2 pairs hence selling 1 pair. They sound smooth with fast transients. Best to crossover ~600hz. Crossover 1000hz with a steeper slope. Tested on diyaudio with the AETD12, GPA414, which they compare very favorably.. The 12NDA has low harmonic distortion. 66% off, asking $200/pair + shipping.
