Our premium In/On Wall Series has a combined high performance ceramic dome tweeter with ferro-magnetic fluid for effective heat dissipation. The midrange incorporates an isolated design to minimize distortion.The bass component woofer design dissipates heat outside the speaker cabinet so as not to affect internal speaker air pressure, allowing for efficient heat dispersion. The revolutionary crossover, responsible for the transition between high, mid, and bass frequencies, is seamless. The space-saving ultra-slim cabinet design has a depth of 13.5 mm, with a 5 mm thick speaker fabric grill. The speakers perform with a short response time and provide good control at higher volumes.
