These 2-way speakers feature 5-1/4" polymer-coated woofers, 1/2" poly dome tweeters and built-in subwoofer crossover points to ensure powerful audio. The 70Hz - 20kHz frequency response provides accurate sound reproduction.
Overall the sound was disappointing. The high end is weak and the sound is muddy. The speaker grilles are interchangeable for indoor or outdoor use but they are on so tight likely removing the grille will damage it. The instructions suggest hammering it off with an ice pick.
