The Polk Audio PSW10 review is about a good combination of power and restraint. Polk Audio is an award-winning developer and maker of high-end audio products, as well as Directed Electronics, Inc.'s best-known brand. Let’s see Polk Audio PSW10 specs.
The American device is equipped with the most solid 30-cm bass driver in our review, a 260-watt amplifier and has advanced connectivity options. The crossover adjustment range is 60 - 110 Hz. The phase changes only discretely. The driver size is 10 inches. The power of the amplifier is rather low - 50 watts. The first impression is manifested by crushing dynamics in the entire bass band (slack is felt only at critically low frequencies, which, in theory, should still be on the shoulder of his 30-centimeter bass). The second is in the perfectly damped bass aftertone transmission. A specific feature of this model is a slightly crumpled “fast” speaker. The PSW10 blow will transmit softly, but it will not torment the hearing with belated low-frequency peals, like some of its rivals.
This is a fairly compact subwoofer, just 14.5 inches high, 14 inches wide, and 15 inches deep; thanks mostly to its robustly constructed MDF (medium-density fiberboard) cabinet, it weighs a hefty 26 pounds. The front panel without a mesh pleases the eye with a pretty silver color. It houses a 25 mm speaker with a polymer composite diffuser with a concave dust cap, as well as a round FI port of a rather large diameter. The knobs for adjusting the level and cutoff frequency of the low-pass filter are output to the rear panel, stereo inputs are linear and high-amplitude. The output is only high-amplitude.
For connectivity, you get stereo speaker-level inputs and outputs as well as RCA line-level inputs. All that's missing is a direct/LFE input that bypasses the onboard 80Hz-to-160Hz crossover control. The LFE cinema input is supplemented with separate connectors for the right and left channels, and the “hot” speaker terminals are duplicated by the corresponding acoustic outputs.
