The PSW 111 delivers surprisingly deep, musical bass down to about 36Hz from a compact enclosure, adding a full low octave to small or nearfield systems. Its compact footprint and easy setup (RCA and speaker inputs) make integration painless, while Future Audiophile notes it’s an affordable way to get fuller sound without a large subwoofer.
Pros
- Extends to roughly 36Hz for its small sealed cube, providing surprisingly musical low-end for desktop and small-room setups.
- Blends smoothly with nearfield and small speakers, restoring a lower octave and noticeably improving musical engagement.
- Ultra-simple, no-fuss setup with both RCA line and speaker-level inputs—easy to integrate without advanced configuration.
&
Cons
- Lacks advanced features or DSP—no app control or room-correction options for tuning to a room.
- Utilitarian build and finish: simplistic grille and plastic-y speaker inputs make it feel less premium.
