Pure Resonance Audio MC2.5B 2.5 Inch Mini Cube Speakers Pair

Compact Pivoting Speakers for Surround, Height, and Background Audio

The Pure Resonance Audio MC2.5B is a compact passive speaker pair designed for surround channels, height effects, satellite speaker use, whole-home audio, and background music systems. Each speaker assembly uses two 2.5" drivers, giving you four total drivers across the pair.

The pivoting dual-cube design lets you aim sound directly toward the listening area or angle it toward nearby surfaces for more flexible placement.

Who Should Choose the MC2.5B?

Choose the MC2.5B when you want very small passive speakers that can be aimed precisely for rear surround, height, satellite, or background-music duties.

Because the frequency response begins at 200Hz, these speakers are not intended to provide deep bass on their own. For home theater or fuller music playback, pair them with a compatible subwoofer.

Dual 2.5-Inch Pivoting Cube Design

Each MC2.5B speaker assembly contains two 2.5" drivers mounted in a pivoting dual-cube configuration. The design allows the two speaker sections to be aimed to help spread sound more effectively through the listening area.

Pure Resonance Audio specifically notes that the speakers can be aimed directly into the room or used to reflect sound from nearby walls.

15W RMS / 30W Peak Power Handling

The MC2.5B is rated for 15W RMS and 30W peak power handling at 8 ohms.

These are passive speakers and require a compatible amplifier or AV receiver. The power rating describes speaker handling capability, not built-in amplifier output.

Best for Surround and Satellite Use

The compact size and adjustable aiming make the MC2.5B especially useful for rear surround channels, compact satellite positions, height effects, and secondary listening zones where larger speakers would be visually intrusive.

For home theater use, connect them to a compatible AV receiver and add a subwoofer for low-frequency reproduction.

200Hz–20kHz Frequency Response

Pure Resonance Audio specifies a frequency response of 200Hz–20kHz. This makes the MC2.5B best suited to midrange and high-frequency reproduction rather than standalone full-range music playback.

Included Swivel Wall Mounts

The included glass-filled nylon mounting brackets provide flexible positioning. The brackets support approximately 90° rotation and 20° tilt, helping you aim the speakers toward the listening area.

Cable routing through the mount helps keep the finished installation cleaner.
