Tang Band W2-2040S 2" RBM Micro Subwoofer 4 Ohm

Tang Band designed their revolutionary RBM (Real Balanced Mode) flat subwoofers for ultra-linear operation, while remaining as thin as possible. The secret to their low distortion performance is in the patented symmetrical suspension system.

While most subwoofers rely upon a spider/surround combination to keep the cone travel linear, Tang Band has developed a new injection molding process that incorporates front and rear cones, as well as dual opposed surrounds.

Similar to an isobaric subwoofer alignment, the two cones work together to modulate a single column of air, reducing non-linear harmonic distortion. The added mass of the rear cone/surround assembly also reduces free air resonance.

Tang Band's W2-2040 2" RBM micro subwoofer features extensive venting on the rear cone and voice coil former to keep the large, overhung, neodymium-powered voice coil cool. Additionally, it offers low distortion frequency response that reaches down to 75 Hz.
