On-wall bipole speakers are usually mounted at head-height and are therefore dangerous obstacles for movie watchers who get up to go to the bathroom in a darkened home theater. (Talk about being able to feel the surround effects!) Sunfire’s new on-wall bipole speaker features the company’s Cinema Ribbon high frequency drivers and a Tweeter Shaping circuit that allows the installer to tailor the high frequency output without affecting the crossover relationship between the Cinema Ribbons and the cone woofer. In addition to being the only on-wall ribbon bipole speaker available, the new CRM-21BP is one of the slimmest on-wall bipoles – only 3 5/8” deep.
