Wharfedale PowerCube SPC-8, SPC-10 and SPC-12 Subwoofers

By  |  0 Comments

Wharfedale announced three PowerCube Series active subwoofers, models SPC-8, SPC-10 and SPC-12 with 200mm, 250mm and 300mm drivers respectively. Each subwoofer offers continuously adjustable crossovers, an 'infinite baffle' design that Wharfedale claims delivers faster, more accurate bass response than ported bass reflex designs.

The PowerCube series is powered by Class D power amplifiers at 150-watts for the SPC-8, 200-watts in the SPC-10 and 350-watts for the SPC-12, which provides deep bass to 30Hz. The downward-firing drivers featured throughout the range are capable of large excursions whilst maintaining exceptionally accurate pistonic movement. The low pass filter slope can be adjusted from 30Hz to 150Hz, while the steep upper bass roll-off slope produces cleaner bass.

All PowerCube models incorporate an ingenious movement sensor that detects when someone is in close proximity to the subwoofer, automatically illuminating the top-mounted controls. This makes it easier to adjust the settings in dimly lit rooms — ideal for when you wish to make little tweaks, but not hit the lights.

Peter Comeau, Director of Acoustic Design for IAG (Wharfedale's parent company) commented:

“The aim was create a range of high-quality powered subwoofers to suit a variety of rooms, tastes and budgetary requirements. Whichever Wharfedale speakers a customer chooses — Diamond 10 Series, the new Jade models or speakers from another Wharfedale range — there is a PowerCube sub that will suit perfectly. The high-performance Class D amplification, long-throw drive units and rigid sealed-box construction combine to deliver bass that is supremely clean, powerful and controlled, from subwoofers that are easy to site and simple to operate.”
