The RS600i is a 6.5”, two-way ported speaker with an open-ceiling enclosure design that delivers effective low-end response (58 Hz) and 100° off-axis performance (2 to 10 kHz, independently verified). SoundTube’s proprietary BroadBeam waveguide tweeter system delivers consistent high-performance audio across the operating bandwidth. The RS600i speaker design incorporates a low-profile grille, proprietary motor-board, and a six-position tap switch with transformer bypass position. Hanging hardware is included and features a SpeedClamp self-locking wire grip for fast, easy, and secure installation.
