Dayton Audio SUB-800 8 in Powered Subwoofer - Compact, Clean Bass

Our review of the Dayton Audio SUB-800 finds it a compact powered subwoofer that suits small home theaters and listening rooms where space is limited but bass impact matters. The single biggest reason to buy is its combination of a heavy duty long-throw 8 in woofer and a downward-firing flared port design that produces surprisingly clean, powerful low end without boomy resonance. Setup is straightforward and the unobtrusive textured black vinyl finish helps it blend into a living room or dedicated media area.

Key Features

• Downward-firing flared port: Delivers tighter, more controlled bass by reducing port turbulence and minimizing audible port noise at playback levels typical for small rooms.
• Heavy duty long-throw 8 in woofer: Provides solid low-frequency extension and punch for music and movie effects while keeping the cabinet compact.
• Selectable Auto-on mode: Lets the subwoofer power up only when a signal is present, simplifying integration with a bookshelf speaker setup and saving energy between listening sessions.
• Compact footprint: Fits into small home theater and listening room layouts without dominating the space, making placement easier in tighter setups.
• Textured black vinyl finish: Offers a clean, unobtrusive aesthetic that pairs well with most AV furniture and speaker systems.

Who It's For

The SUB-800 is ideal for listeners with small to midsize rooms who want a discreet sub that still delivers impactful bass for music and movies. It pairs particularly well with bookshelf speakers and systems where space is at a premium but low-end reinforcement is desired.

Those who need extreme output for large rooms, or who demand adjustable high-end DSP features and multiple crossover presets, should look at larger or more feature-rich subs. For everyday listening and modest home theater use, this sub delivers the essentials cleanly and affordably.
