Know before you buy
The R350 is designed for versatility and can be used as a left, center, or right channel speaker. Its slim profile makes it an excellent choice for front-stage setups where space is limited.
Because the R350 uses a sealed cabinet, it does not rely on rear-firing ports to produce bass. This makes it much easier to place in tight spaces, on shelves, or mounted directly to a wall without worrying about boomy, distorted sound.
The R350 is compatible with most standard receivers, supporting 4, 6, and 8-ohm outputs. It performs best with amplifiers rated between 25 and 200 watts per channel.
This certification indicates that the speaker can reproduce frequencies up to 50 kHz, well beyond the range of standard human hearing. This ensures that high-resolution audio files and modern soundtracks are reproduced with greater detail, clarity, and precision.
The R350 measures 30 inches wide and 5.5 inches tall. You will need to ensure your wall mounting hardware is rated to support its 20-pound weight and that you have enough clearance for the speaker's depth of 7.4 inches.
The Pinnacle tweeter is designed for wide dispersion, which helps project clear, crisp dialogue across a broader seating area. This ensures that voices remain intelligible even if you are sitting off-center from the screen.
