"A true champion of subwoofers, in terms of performance and price – it’s a quality piece of budget equipment."

The SW-150 Subwoofer from Wharfedale offers a level of performance previously unheard of in its class, striking the perfect balance between power and sound quality. Revolutionary drive units, amplifier modules and filter stages feature on every model of Wharfedales SW Series of subwoofers. In each model it is possible to switch off all filters and allow the AV processor to control the effective frequency range of the subwoofer. This is preferable in high-end systems.

Revolutionary drive units, amplifier modules and filter stages feature on every model. They strike the perfect balance between power and sound quality, offering remarkable sound pressure levels, yet retaining enough control to be considered audiophile in quality. This is possible only through the use of some space-age materials and cutting-edge technology in our drive units.

Solid, well-engineered power amplifiers, dedicated to the production of low frequency energy are used across the range. Power is targeted specifically at the most important section of the bass spectrum, with very little loss and a controlled roll-off allowing for superb integration with all hi-fi and home cinema systems. The filter section controls the integration with your main speakers and ensures the transition is seamless. Designed using six discrete circuits, signal purity is regarded as paramount. Each circuit has a different crossover frequency (35Hz to 85Hz in 10Hz steps). The filter is 12dB/octave on the SW-150 and 24dB/octave on the larger models. Finally, the Tri-lam cone is revolutionary in terms of technology and performance.which is one of the most advanced cones ever seen in a moving-coil loudspeaker, coupled with an elongated voice coil with a maximum excursion of 24mm.

For the price I can't recommend this sub highly enough. The bass is warm and more noticeable without being boomy. For me this product was a definite upgrade over my previous entry level sub (Jamo SUB200)

Good all round unit for the price, limited low frequency response, but expected for size of enclosure. Nice finish and controls easy to understand.
