ROCKUSTICS

ROCKUSTICS landscape speakers are offered in both 4 ohm and 8 ohm versions. For example, the STONEHENGE II-G, ECONOROCK-G, ECONOROCK-S, COCONUTZ, and XT-SURROUND STONE 8-S are rated at 4 ohm, while the XT-POWERROCK-S and ROCKY JR.-G are rated at 8 ohm. The choice affects amplifier loading and wiring configuration. Lower impedance allows more power draw from a given amplifier channel but limits the number of units that can be paralleled. Higher impedance units are easier to combine in series-parallel arrays or to use with transformers for constant-voltage distributed systems. Specifying the correct impedance for each zone helps avoid amplifier overload and ensures consistent output across the installation.

Yes. All ROCKUSTICS landscape speakers and subwoofers listed are passive designs, meaning they do not contain built-in amplification. They must be connected to an external amplifier or receiver. This is typical for permanent outdoor audio installations where amplification is centralized and protected from the elements. The passive design also allows the use of a single amplifier to drive multiple speakers through series, parallel, or distributed wiring schemes. When planning a system, verify that the amplifier's power output and minimum impedance load are compatible with the number and impedance of speakers in each zone. For subwoofers like the Subscape 8, a dedicated amplifier channel or separate subwoofer amplifier is usually required.

The STONEHENGE II-G measures 17-1/4 inches in overall width and 17-3/4 inches in overall height. It is one of the larger full-range landscape speakers in the line. For comparison, the XT-POWERROCK-S shares the same 17-1/4 inch width and 17-3/4 inch height. The XT-SURROUND STONE 8-S is 17-1/4 inches wide but 14 inches high. The ECONOROCK-G and ECONOROCK-S are smaller at 12-1/2 inches wide by 10-1/2 inches high. The COCONUTZ is the most compact at 7 inches wide by 12-1/4 inches high. The ROCKY JR.-G is the largest at 20 inches wide by 16 inches high. These dimensions help determine placement and coverage in landscape designs.

The Subscape 8 is a landscape subwoofer. Its purpose is to reproduce low-frequency content below the range of the full-range landscape speakers in the ROCKUSTICS line. It is intended to be used in conjunction with two-way models such as the STONEHENGE II-G, ECONOROCK-G, or XT-POWERROCK-S to create a full-range outdoor audio system. Because it is a passive subwoofer, it requires an external amplifier, and often a dedicated amplifier channel with appropriate low-pass filtering. The Subscape 8 is designed to blend into outdoor environments, consistent with the aesthetic approach of the other ROCKUSTICS products. Specific frequency response and power handling data should be confirmed from the product datasheet.

ROCKUSTICS speakers are designed for outdoor distributed audio in residential and commercial landscapes. Typical applications include gardens, patios, pool decks, courtyards, and planted areas around buildings. Because they are passive and weather-resistant, they can be used in systems that cover large outdoor spaces with multiple speakers. Commercial settings might include hotel grounds, retail centers, restaurants with outdoor seating, and corporate campuses. The enclosures are shaped to resemble natural elements, which reduces visual impact compared to conventional outdoor speakers. For projects requiring low-frequency reinforcement, the Subscape 8 can be added. System design should account for amplifier power, wiring distances, and impedance loading to ensure even coverage and reliable operation.

3G Electric stocks multiple ROCKUSTICS SKUs and provides access to product datasheets, dimensional data, and impedance specifications needed for system design. For procurement teams, this means a single source for model selection, quantity pricing, and logistics coordination. 3G Electric ships globally, so orders can be consolidated and delivered to project sites or staging warehouses. Technical support includes help with model cross-referencing and verification of specifications against project requirements. Because the product line includes several similar models with different dimensions and impedances, having a distributor that maintains current data helps reduce specification errors.
