The EVE Audio TS107 6.5-Inch Active Subwoofer offers even more bass for your studio extending the low-end of your setup. It features a frequency range 36 to 300 Hz, a 6.5-inch woofer size, and 102 dB maximum sound pressure level. It delivers adequate and precise control over the bass frequencies in your room, without any low-port noise distortion since all subwoofers have a passive radiator. All subwoofers feature the powerful accurate and low distortion sound. Your system will sound as a whole, not just a sum of parts. Every ThunderStorm subwoofer has detailed controls like switchable satellite filters (full range and 80Hz), phase switch controls (0-degree, 180-degree) and variable subwoofer filter frequencies (60 to 140Hz) to let you tailor and adjust your ThunderStorm to your specific room. The TS107 model features a very efficient 100W PWM amplifier that drives a proprietary 6.5-inch woofer. This guarantees a frequency response of down to 36Hz, up to 300Hz, for a maximum output power of 102 dB (SPL at 1m) with plenty of power for most needs. 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 and Sub Out) for greater convenience. In addition, TS107 features an unbalanced input for connecting SC203, too.More than Just a SubwooferEven if the focus is on the sound the monitor offer a holistic solution that is well thought out from A to Z.Smart-KnobSimply set and save filters and volume.Passive RadiatorThis allows for precise bass reproduction without background noise.Parameter LockYour settings are saved (even without power).Safe Fade-InA slow volume increase when switching on protects ears and equipment.The DSPOne 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, and 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 Passive RadiatorThe particularity of the 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 or 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.
