Rockville 4 Cube 70v Black 3.5 in Commercial Swivel Wall Mount

In this review the Rockville Cube 70V 3.5 in swivel wall mount speakers prove to be a compact, no-nonsense choice for commercial audio needs; they are aimed at restaurants, retail spaces, and offices that need clear background music without a large footprint. The single biggest reason to buy is the combination of true 2-way driver design and 70 volt power taps, which deliver more balanced highs and lows than typical one-way commercial cubes while keeping installation simple and unobtrusive.

Key Features

• 70 Volt options: Multiple power taps of 6 W, 3 W, and 1.5 W allow easy integration into distributed commercial systems and predictable volume control across zones.
• True 2-way drivers: A 3.5 in paper cone woofer and 0.5 in PEI tweeter provide clearer mids and highs compared with single-driver cube designs.
• 360 degree swivel mounts: Included wall brackets rotate fully so installers can aim sound precisely for optimal coverage and staging.
• Shielded metal grill: The protective grill resists dust and damage in busy commercial environments while keeping the look low-profile.
• Complete mounting kit: The pair ships with metal bars, safety cables, screws and a user manual so two-speaker installs are ready out of the box.

Who It's For

The Rockville Cube is best for small to medium commercial installations where space is limited and background music or paging is required, such as cafes, restaurants, small retail shops, and office common areas. The 70 V taps and euro block terminals make it straightforward to connect to commercial amplifiers and multi-zone systems.

Customers seeking deep bass for music-focused listening, very high output for large venues, or decorative finishes beyond plain black should look elsewhere; this model prioritizes clarity and compactness over low-frequency extension and ornamental design options.

Pros & Cons

• True 2-way design gives noticeably clearer highs and midrange compared with single-driver cubes.

• Compact ABS cabinet and shielded grill fit unobtrusively into most interiors.

Cons
