The TSW-90 v.4 is a 10” driver subwoofer with a high-output built-in amplifier and uses a bass reflex port on the back. The v.4 version features a completely redesigned amplifier and circuit boards with higher quality components as well as a heavily modified woofer.

The new built-in amplifier offers slightly higher output power and better performance, resulting in lower distortion and smoother, flatter response. A built-in cutoff regulator maintains optimal performance and safe operation of the amplifier and woofer.

The bass control can operate in higher frequency ranges and can respond quickly to any changes in the audio signal structure. The power cable has been changed to a removable IEC type, which provides better filtering and power supply stability.
