The ONDA speakers are all low-impedance (8ohm), coaxial, with Kevlar woofers, silk-dome tweeters, precision crossovers; essentially true 2-way speakers for professional applications, but ceiling/wall mount. The look of the front panel is minimalist and captivating, and reminds recording studio monitor. The frame-less design, with black ABS frame and white magnetic grids, makes the ONDA speakers extremely discreet. Finally, the grids can be repainted to make them even less visible.
