Get more bass in your studio

What is TS108?
The TS108 is an active subwoofer in EVE Audio's ThunderStorm range with an 8-inch woofer. The maker introduces it as a way to get more bass in the studio.
A 150 W PWM amplifier drives a proprietary 8-inch woofer. Frequency range is 33 Hz to 300 Hz and maximum SPL is 105 dB at 1 m. A passive radiator replaces a port, avoiding port noise according to the maker.
The rear has balanced XLR inputs and outputs (stereo in/out, LFE in, LFE/sub out) and an unbalanced input for the SC203. A satellite filter (full range / 80 Hz), phase switch and a variable 60 to 140 Hz filter help tailor it to a room.
The DSP only affects the bass driver, leaving the satellite signal analog. A remote is included to adjust the subwoofer and system volume from the sweet spot.
Passive radiator design
A passive radiator supplements the bass instead of a port. The maker says this avoids air turbulence noise and port resonance and lets compact cabinets tune lower.
8-inch woofer with PWM amplifier
A 150 W PWM amplifier drives a proprietary 8-inch woofer, with response from 33 Hz to 300 Hz, which may help extend lows your main monitors do not reach.
Stereo and LFE connections
Balanced XLR inputs and outputs (stereo in/out, LFE in, LFE/sub out) support both stereo setups and surround setups using LFE.
Variable crossover and phase switch
The subwoofer filter is variable from 60 to 140 Hz and phase switches between 0 and 180 degrees. These may help blend with the main monitors in your room.
Analog satellite path
DSP only processes the bass driver and the satellite path has no A/D or D/A conversion. The Pure Satellite function bypasses the subwoofer and its DSP filter section.
Remote and SMART-knob
The remote adjusts subwoofer and overall system volume, while the SMART-knob sets and saves filters and volume. Settings can be locked.
