The high-quality stereo passive loudspeaker delivers powerful and clear sound. The frameless design with a grille that magnetically attaches to the speaker protrudes only 3 mm from the ceiling. The grille can be painted with ceiling paint to create a virtually invisible look for these high-quality speakers. Featuring a woven fiberglass woofer cone, the strength of the woven fiberglass cone helps the cone maintain its shape at very high energy levels, and the low mass ensures a fast, accurate response. The woven surface of the cone delivers smooth, uncolored midrange frequencies. The high-quality rubber surround ensures that these woofers deliver years of consistent, reliable performance.
