To get the big boom, low bass effects from movies and soundtracks, it's important to include a subwoofer as a part of your home theater surround sound system. Acoustic Audio's Cinema Series CS-IW10 subs have been specially engineered to handle major power at the lowest of frequencies. The 10" sub has a high rigidity treated woofer for 25% more power handling than most other subwoofers. It can handle 300 watts of power (150W RMS), and comes equipped with an extended throw drive assembly and butyl rubber surround to deliver ultra quick bass response and precise musical accuracy. It has a mounting depth of only 4.88", so it mounts flush with nearly invisible installation. Not only are unsightly speaker wires hidden in your wall or ceiling, but the speaker's paintable, white grill can be modified to match your home decor.
