Turbosound TSW718

The TSW-718 is a low-frequency enclosure designed for use in applications requiring accurate and powerful reproduction of bass, and particularly upper bass frequencies, at extremely high levels. Its ability to reproduce low-frequency program material with such integrity makes the TSW-718 ideal for both fixed club installations and medium to large touring PA systems.

The TSW-718 incorporates the TurboBass™ device, a unique patented design which employs a high-velocity partial horn loading technique, giving precise cone control at high power levels. Much of the impact of contemporary dance music is concentrated in the upper bass frequencies. It is in this area that the TSW-718 addresses an increasing demand for accurate, high definition bass reproduction, especially in discotheque and club environments. This ability to provide fast, ‘punchy’ low frequency reinforcement also makes the TSW-718 ideally suited for use in medium to large PA applications.

The loudspeaker complement consists of two custom-designed 4” voice coil, doublesuspension 18” drivers, each unit hornloaded via a TurboBass™ device, resulting in a large area horn flare which gives excellent low frequency extension. High motor strength is provided by a massive, precision crafted magnet assembly. The enclosure is dimensioned for optimum truckpack, and features flush handles, EP6 connectors, side driver access panels and heavy duty wheels. The Speakon connectors offer a standardised speaker cable for both high and low frequency enclosures, while the connector pin-outs allow bi-wiring and access to each individual driver. A dedicated fixed installation option (TSW-718i) is also available with XLR connectors but without wheels.
