Gemini PCB4BK Mini Cube Bookshelf Speakers 4" 200W 8Ω Black 1 Pair

Compact cube speakers for desktop

These 4.8-inch black cube bookshelf speakers are sold as a stereo pair and rated at 200 watts peak power. An 8-ohm nominal impedance makes them easy to drive from most amplifiers or AV receivers. The paper-cone drivers deliver a quoted frequency response of 80 Hz to 18 kHz for full-range playback.

Passive design requires external amplification

Each enclosure measures 4.8 by 4.8 by 5.2 inches and uses a wired connection, so you must supply an amplifier or receiver with binding posts or spring clips. Video shielding allows placement near CRT displays without magnetic interference. The compact footprint frees shelf space compared with larger floor-standing models.

Step up from smaller 3.6-inch cubes

This model replaces the 3-inch PCB3BK variant, which handles only 100 watts peak and reaches 90 Hz at the low end. The larger 4-inch driver and higher power rating suit listeners who want louder output and deeper bass extension in the same cube form factor. Buyers needing sub-80 Hz response or powered operation should look elsewhere.
