The E118sw is a high-performance direct radiation subwoofer with a single, 800W, 18-inch, aluminum frame woofer. It’s designed to produce crushing low-end for live performance with kick-drum and bass in the PA or for high-level, high-energy dance music. A threaded, M20 pole socket and speaker pole are provided for sub/satellite use with any of the E Series two-way models. For portable applications it includes attachment points for four optional casters. The subwoofer’s 4-ohm impedance means that a single woofer can be optimally powered by a less expensive amplifier. E Series loudspeakers will perform very well with any quality, professional power amplifier – but by taking advantage of the complete E Series Entertainment System, more performance and options are available. Today’s powered loudspeakers rely on finely tuned digital signal processing (DSP) to achieve a higher level of performance. When used with QSC GXD or PLD amplifiers or with a QSC TouchMix digital mixer, E Series loudspeakers can also take advantage of advanced DSP. QSC has developed E Series DSP settings for all three platforms. These settings support a variety of applications including live sound reinforcement (with and without subwoofers), stage monitoring, dance music and karaoke.  Features: High output, professional quality sound with  800 W continuous power E Series Entertainment System – Advanced digital signal processing tunings and options using QSC GXD, PLD amplifiers or TouchMix digital mixers.

The Baso cabinets are universally useable passive bass cabinets. Their bass reflex design is engineered to be as compact as possible while giving the maximum performance in terms of sound quality and pressure. Their enclosures are crafted out of sturdy high-quality plywood while their elegant design enables them to be placed in any environment.The Baso10 is loaded with a 10” high-performance woofer with an RMS power rating of 225 Watt and maximum power of 450 Watt. The strength of this loudspeaker originates from a four layer wounded 1.5” voice coil in combination with an over-sized ferrite type magnet which provides an unusual high force factor. In combination with the low-loss suspension, this results in a linear behaviour with high efficiency and extremely wide frequency range.These carefully selected high-grade materials in collaboration with accurate acoustical craftmanship results in a deep and true to nature reproduction of bass. The highly-efficient design results in a sensitivity of 96 dB with capability of continuous sound pressure production up to 120 dB. The frequency response ranges from 54 Hz up to 1.2 kHz while going down to 38 Hz at -10 dB.Besides these acoustical aspects, a lot of attention has been paid to all other aspects making it as versatile as possible. The enclosure is compact designed without any sacrifice to robustness due to the 15 mm high-quality plywood material finished with structured coating.Connections are made using two speakon compatible connectors located in a recessed connector dish, allowing link-through to other cabinets. This also allows close placement to any wall or corner.
