This article covers OSD Audio 6.5インチ ブラウン ハイファイ アウトドア ロック スピーカー 150W 耐候性 パッシブ ステレオペア RS670.
Overview
The OSD Audio RS670 is a pair of passive outdoor rock speakers featuring 6.5-inch drivers. Designed to blend seamlessly into gardens, patios, and decks with a realistic rock appearance, these speakers deliver clear, distortion-free sound even in outdoor environments. With a maximum power handling of 150W, they are suitable for medium-sized outdoor spaces. Built with an aerospace-grade multi-layer composite cabinet, the RS670 is engineered to withstand rain, temperature extremes, and other harsh weather conditions. As passive speakers, they require an external amplifier or receiver, offering flexibility in system configuration.
Connectivity & Compatibility
The RS670 connects to an amplifier or AV receiver via standard speaker wire. For outdoor installations, it is recommended to use waterproof-rated speaker wire and bury it directly underground to keep electronics safe. The speakers are compatible with most amplifiers that support 4-8 ohm impedance and output power between 50W and 150W. No additional connectors or adapters are needed; simply strip the wire and connect to the amplifier's speaker terminals. The speakers are sold as a pair and can be wired in stereo for a wide soundstage.
Product Info
The OSD Audio RS670 is part of the company's outdoor speaker lineup, designed for residential and light commercial use. Priced around ¥40,000 on Japan, it sits in the mid-range tier for outdoor speakers. The package includes two speaker units only; speaker wire and mounting hardware are sold separately. Warranty typically ranges from one to two years, depending on the retailer. The speakers are available in brown color to match natural surroundings. Market positioning is entry-to-mid-level, offering a balance of aesthetics, durability, and sound quality for outdoor audio enthusiasts.
Best Use Cases
Homeowners with gardens or patios: The RS670's rock-like appearance blends into landscaping without being an eyesore. It provides clear background music for relaxing outdoors. However, those seeking very high volume levels may need a more powerful system. Outdoor party hosts: With 150W power handling, these speakers can fill a medium-sized yard with sound for barbecues or gatherings. The stereo pair creates an immersive audio experience. For large events, consider adding a subwoofer or upgrading to higher-output speakers. * DIY audio enthusiasts: Passive design allows full control over amplifier choice and wiring. You can customize the system with a high-quality amp and bury cables for a clean installation. Beginners should note that an amplifier and speaker wire are not included, so additional purchases are necessary.
