This unique systems perfomance has been taken to a whole new level by now using the Wharfedale Moviestar 70+ Sub .TDK’s Tremor ‘multimedia loudspeaker system’ (as they used to call them back then) was one of the most intriguing designs of the decade, in my opinion, when it was introduced in 2001. The Tremor S-150, S-60, and S-40 were the company’s original speaker systems, with a total of three available. Each had a powered subwoofer and two satellites using the (at the time) cutting-edge NXT SurfaceSound technology.

Unlike traditional pistonic speaker designs, this created various vibration patterns across the surface of a panel, in this case working at 200 Hz to 20 kHz. It also had a much wider dispersion pattern than standard moving coil speakers.

Turn it on, and you’re rewarded with an incredibly clean and open sound with excellent transient speed and minimal coloration
