KEF - PSW 1000.2 Subwoofer

The PSW series is targeted at home theater and music multimedia applications, as confirmed by the Music / Cinema mode switch on the rear control panel. The slotted bass-reflex port, as well as the loudspeaker, is directed downwards. This housing design increases the sound pressure to 106 dB by working with the ground . This requires the use of legs or screw spikes, which are included in the set. The quality of the housing materials is at an average level, the interior looks much better, where we can find a large toroidal transformer XUZHOU Gloria Electronics model: TD-230-0100A with voltages I / P: 0-115V, O / P: 24.5V / 2.9A- 024.5V / 2.9A. Two NOVER LS series capacitors with a capacity of 8200μF placed on a good quality PCB with Toshiba 2SA 1943 transistors. The entire amplifier with electronics is separated from the inside of the housing with a plastic bowl, whose task is to better seal the housing. The slot port and the downward-facing speaker amplify the bass that is more noticeable and more evenly distributed in the room. There is probably no timing as good as a closed housing, but it also does not slow down as much as a typical structure with a resonance tunnel. The 20cm bass driver is driven by a 100W Class D amplifier . The control panel placed on a fairly large aluminum plate allows you to control the gain, 0-180 phase settings, 40-140 Hz frequency cut-off control and music / cinema selection switches. In addition, we get switches for filter settings 12/24 dB per octave, along with the possibility of switching the power supply to stant-by auto / manual mode.
