- 1-inch (25 mm) soft dome tweeters/6.5-inch (16.6mm) or 4-inch(10.2mm) aluminized woofers.
- Bass-reflex design with flared, rear-firing port: Increases system efficiency and bass output.
- Waveguide: A unique tweeter faceplate that provides more uniform dispersion in the critical frequency range of 2-10 kHz. Dynamics and clarity are enhanced while distortion is significantly reduced.
- Centre-plug: Replaces the typical dust cap and eliminates cone breakup, for a woofer with faster “attack” and tighter, more natural bass.
- Aluminized woofers: Increases cone rigidity for solid bass.
- Individually chambered woofers (S 526): Separately housed woofers minimize driver interference.
- 5-way binding posts: Allows for multiple connection options with wire up to 12 gauge (AWG).
