The KEF PSW2000 is a subwoofer that provides considerable bass performance for various audio applications, including home theater and music systems. It features a 10-inch downward-firing driver which enhances its ability to produce deep, impactful bass while minimizing distortion across a range of frequencies. The design of the PSW2000 is understated yet elegant, available in a charcoal grey casing with a glass top that adds a stylish touch to home decor. The unit is powered by an amplifier capable of delivering up to 200 watts of power (with some modifications allowing up to 250 watts), contributing to its dynamic sound output. However, users have noted some design flaws, particularly regarding reliability. Many have reported that the PSW2000 is prone to overheating and power supply issues, necessitating manual shutdown after use, as it does not fully power down in standby mode. Reports of modifications exist, which can improve its longevity and performance. The subwoofer can efficiently handle different sound types, providing clarity for music and cinematic effects alike. Overall, it excels in producing a strong bass response and can integrate well into larger living spaces without overwhelming smaller rooms. Users should consider its maintenance requirements and potential need for repairs when assessing its suitability for their audio setup.
