EVE Audio TS108 8″ Active Subwoofer

Every ThunderStorm subwoofer has detailed controls like switchable satellite filters (full range and 80Hz), phase switch controls (0°, 180°). and variable subwoofer filter frequencies (60….140Hz) to let you tailor and adjust your ThunderStorm to your specific room.

The TS108 model features a very efficient 150W PWM amplifier that drives a proprietary 8″ woofer. This guarantees a frequency response of down to 33Hz (on the lower end), up to 300Hz, for a maximum output power of 105 dB (SPL @ 1m).

All in all, the ThunderStorm subwoofers will make any system sound better and more complete.

As with every other EVE Audio subwoofer, you get balanced XLR In- and Outputs (Stereo In and Out, LFE In, LFE/Sub Out) for greater convenience. In addition, TS108 features an unbalanced input for connecting SC203, too.

One thing worthy of mentioning is that the DSP section, which uses a high resolution BurrBrown converter, only affects the bass driver operation. The signal path to the satellite speakers is kept purely analog, with no A/D/A conversions whatsoever. That’s why the “Pure Satellite” function, when activated, completely bypasses the subwoofer and DSP filter section, and will only allow you to adjust your satellite’s volume.

The included remote control will let you adjust not only the subwoofer’s volume but also the complete stereo system’s volume while sitting comfortably in your sweet spot.

The particularity of our extremely powerful and accurate subwoofer resides in the passive radiator used that replaces the common bass reflex tube. With this design all audible noise due to air turbulences disappear completely.

Unwanted disturbing pipe resonances (at lambda/2 and multiples) are eliminated, which are unavoidable when applying the principle of a two-sided pipe opening (bass reflex port). The suspension of the passive radiator has a restoring force underneath its tuning frequency and reduces inaudible excursions in the subsonic range. This in turn results in reduced intermodulation distortion in the working range.

The passive radiator allows a particularly low tuning or lower cut-off frequency in a very compact cabinet.
