The X-mini™ MAX II Capsule Speakers™ offer an outstanding stereo performance with its open and angled 40mm drivers designed to deliver directional sound. The two modules are held together by a magnetic base and can be separated to be used individually as a mono speaker or together for stereo effect. Just a simple twist and turn will reveal the patented accordion-like Bass Xpansion System™ (BXS™) which successfully mimics the resonance of a subwoofer. The X-mini™ MAX II Capsule Speaker™ also features the Buddy-Jack function to enhance the volume.
