The S8.4 powered studio subwoofer builds upon KRK’s legacy for sonic accuracy in a compact form factor. The custom-voiced, glass-aramid woofer delivers tight, defined bass, while the Class-D power amplifier dramatically increases transient response, control and punch. The four-position selectable crossover lets you adjust the subwoofer setting easily to your existing monitors.

Pairing the S8.4 subwoofer with KRK or another studio monitor delivers an optimized mixing and listening experience with extended low end, while the exclusive bypass-control feature provides full range audio to the monitors without switching off the subwoofer. KRK’s S8.4 subwoofer doesn’t just deliver precise bass and a rich feature set: it’s the next dimension in subwoofer performance.

The Genelec 5040B is an extremely compact active subwoofer designed to complement up to five 6010B's with accurate and dynamic bass response reaching down to 35 Hz. Matched perfectly with the 6010B's, the 5040B conveniently features a remote volume control allowing adjustment of the entire sound system as well as versatile acoustic controls for perfect room integration.

Our Intelligent Signal Sensing (ISS) feature, reduces power consumption to less than 0.5 watts by automatically switching the active monitor to standby, when no audio signal has been detected for some time. When it receives an audio signal again, the loudspeaker turns back on.

ISS is fully compliant with the latest EU requirements and the ErP 2013 Directive for electronic devices.

Designed by Genelec's R&D team in co-operation with internationally acclaimed Finnish designer Harri Koskinen, the 5040B subwoofer features an unobtrusive, modern appearance.

The 5040B features a magnetically shielded downward firing 6 1/2" bass driver attached to a die-cast aluminium base plate.

The base plate also serves as the chassis for the 40 Watt amplifier and crossover filter circuitry. The 5040B packs a respectable punch of 98 dB maximum sound pressure level

7" Subwoofer

Our range of Subwoofers follows our policy of using only high quality components. This has enabled us to bring the best possible products to the market place. We have paid the highest attention to properly extend the frequency range of our speakers and have put even more care into our subwoofer designs. Not only care, but also a lot of testing and abuse.

So you can rest assured that when you buy a TS (ThunderStorm) subwoofer from EVE Audio, you will be getting a first grade product that delivers adequate and precise control over the bass frequencies in your room, without any low-port noise distortion since all TS subwoofers have a passive radiator. Your system will sound as a whole, not just a sum of parts.

All subwoofers feature the powerful accurate and low distortion sound reproduction that is the hallmark of all EVE Audio studio monitors.

Tech Talk

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 TS107 is the smallest model in the range of EVE Audio subwoofers and features a very efficient 100W PWM amplifier that drives a proprietary 6.5" woofer. This guarantees a frequency response of down to 36Hz up to 300 Hz, for a maximum output power of 102 dB (SPL @ 1m).

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.

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.

Passive Radiator

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.
