Klipsch has unleashed three new subwoofers each with BASH digital hybrid amplification.

Top of the range is the SW-308 (£799), with its 300-watt BASH amp and an 8in custom-made, non-resonant woven fibreglass drive unit squeezed into its 11in³ cabinet. It also has a pair of 8in dual passive radiators and can produce bass frequencies down to 26Hz.

The SW-112 (£599) has the same amplifier but uses a single 12in drive unit in a slot-ported reflex cabinet. It’s finished in black pica, it also delivers bass down to 26Hz.

The budget model is the SW-110 (£499), which uses a 20watt amp and a single 10in driver to give bass down to 28Hz.

All three models consume just 1W in standby mode.
