For just $182.49, below its 30-day average of $200.83. The 90-day average sits at $210.52 and the 180-day average at $207.07, so this price cuts deeper than what you would typically see on these speakers.

What You're Getting

The RBS-52 is a passive bookshelf speaker designed for high-fidelity sound in a compact cabinet. Each speaker packs a 5.25-inch rigid carbon fiber cone woofer with a butyl rubber surround and a 1-inch silk dome neodymium tweeter.

EARTHQUAKE's PistonMax Technology shifts the surround to the outer edge of the cone, increasing surface area by 20 percent for more output and efficiency. The double-ported bass reflex cabinet tunes to 40Hz.

Frequency response spans 30Hz-20kHz with 8-ohm impedance and 90dB sensitivity. Power handling runs 50-300 watts per speaker. The matte black finish includes gold-plated binding posts, a removable magnetic grille, and a built-in wall mounting bracket.

Who This Is For

Best for: anyone building a 2.0 or 2.1 home theater system who wants more bass than typical budget bookshelf speakers deliver. Also a strong fit for near-field music listening in a small studio or desktop setup.

Skip these if you need powered speakers with a built-in amplifier.

Final Verdict

The $182.49 price undercuts the 30-day average by nearly $20 and lands below what these typically settle at. If you need compact passive speakers with real low-end extension. This is the price to move on.
