SKU SUBSERIES450 Categories , Brand:

PSB’s SubSeries 450 is a compact yet very powerful subwoofer housed in a beautifully finished fine furniture cabinet. PSB’s legendary design and engineering prowess is evident in the choice of a 12″ active woofer supported by two 10″ passive radiators (PR). This sub is dead flat to 20Hz and can produce well in excess of 100dB sound pressure level at these ‘felt not heard’ extremes. There is plentiful power to reproduce movie sound effects at lifelike levels. The SubSeries 450 is also exceptionally accurate and musical, and it can clearly enunciate the full power and majesty of a live symphony orchestra.

The SubSeries 450 stands at the head of a range of PSB subwoofers renowned for their exceptional performance and value. Whether for music or movies, the SubSeries 450 subwoofer delivers powerful, tight, accurate bass that is truly exciting to experience.
