here has never been a product hailing from the prestigious Polk Audio that hasn't captured our undue attention. From their towers to their bookshelves, we've loved these reasonably priced, well designed little beasts all the way from Washington, USA. Now, we bring to you their small wall hugging PSWllO subwoofer, which by the looks of it, hasn't let go of the company's late-70s aesthetics.
The gentle curves cornering the PSW110 give its cherry finished cabinet just the smoothness and gentleness it deserves. This us to believe the driver has lost a couple of inches. The subwoofer sits atop of 4.1" spikes that gives the downward firing port enough room to gain some momentum before thumping the floor. All of these elements, if looked at from the aesthetic sense, contribute heavily to giving the 110 that '70s look. And to top it off is the black wire-mesh of a grill that guards the front-firing driver. If you get the cherry finished sub instead of the black one, you might want to make sure it matches the rest of the 5.1 speaker set, because these retro looks need a lot of the living room to match it.
This little guy isn't as little as he looks, blessed with a 10" woofer hooked up to a 100W (continuous) amplifier. That downward firing port is present in all the PSW subwoofers (besides the PSWlO) and increases the bass impact considerably. It also adds to the omnipresent nature of a subwoofer in a dark room, allowing the front firing driver to disappear. The woofer itself has been constructed using a composite material instead of plain paper, so that it still has the quickness of paper but the rigidity of blending paper with a stronger material. Polk claims to have used a state-of¬the-art Klippel Distortion Analyser that would allow the engineers to optimise the woofer's motor structure, voice coil alignment and suspension.
At the same time, using laser technology, Polk was able to analyse the speaker's behaviour at a microscopic level, thereby being able to tune out unwanted resonance and distortion. And the only way to that was to get the right combination of materials, geometry and construction techniques, both in the driver and the cabinet. As far as connectivity goes, the 110 consists of the standard LFE, line and speaker level inputs along with a simple level knob. There's also a crossover knob that goes from 60Hz to 160Hz. All of these ports and knobs are housed on the back of the sub, out of the listener's eyes.
