Polk Audio PSW-111 - Active Subwoofer

Key Specifications & Features

8″ front-firing driver (Dynamic Balance® composite woofer) in a bass-reflex (ported) cabinet.
Built-in amplifier: ~150 W continuous, up to ~300 W dynamic peak. Frequency response quoted approx 36 Hz to 250 Hz (some sources say down to 38 Hz), so decent low-end extension for its size.
Adjustable low-pass crossover (e.g., 60-160 Hz in some specs) and phase switch for better integration with the main speakers.
Compact size: e.g., ~11″ W × ~12.3″ H × ~15″ D (approx 27.9cm × 30.8cm × 33cm) and weighing about 20.3 lb (~9.2kg) in one spec listing.
Rear panel includes line-level (RCA) input/LFE input and speaker-level inputs/outputs, giving flexibility for integration with various setups.
Port is downward-firing (or bass reflex) to increase bass impact whilst keeping a compact front profile.
