Acoustic Audio PA-500X Speakers vs Rockville RSG15.4 15" 3-Way Passive Speaker

The Rockville RSG15.4 is the better pick for DJs, parties and live PA: its 15-inch woofer, 102dB sensitivity and 4-ohm load deliver far more bass and volume per amplifier watt. The Acoustic Audio PA-500X is a small bookshelf-style pair for karaoke, studio or home stereo where a single 5-inch woofer is enough and lighter cabinets matter. Build differs too: the Rockville is a heavy carpeted gig cabinet with steel corners and SpeakON, while the PA-500X is a light MDF pair with binding posts and 1/4-inch jacks. Owners rate the PA-500X modestly at 3.8 of 5; the Rockville trades portability for output.

• Choose the Acoustic Audio PA-500X if you want a light, compact pair for karaoke, home stereo or a small studio and already have an amp that takes 8-ohm loads.
• Choose the Rockville RSG15.4 if you need party-level bass and volume from a single cabinet and can carry a heavy speaker and feed it 4 ohms.
