Mica-Filled Polypropylene Woofers

The mica-filled polypropylene cone achieves new standards in transient speed and dynamic range because of its phenomenal rigidity and improved stiffness to mass ratio. The inverted butyl surrounds, the BumpBackTM mag- nets and the rigid steel basket are all optimized for large excur- sions of the cone. In this way, each of the HD speakers deliver exceptionally deep and detailed bass at realistic sound pressure

levels, without the mechanical- ly induced limiting and distortion of typical designs.

ElastoDynamicTM Hybrid

Dome Tweeter

Constructed from a composite matrix of elastomers and natural fiber substrates, the Elasto- DynamicTM tweeter offers extend- ed high frequency response with- out any harsh ringing or over- shoot. Additionally, the elas- tomers offer the added benefit of weather resistance, making it

uniquely suitable for use out- doors or in moist environments.

Acoustic Fine Tuning

An installer set “NORMAL /PRES- ENCE” control located behind the speaker baffle allows the speaker to be tuned to your par- ticular room acoustics. You can adapt the sound for a room with lots of furniture, heavy drapes and wall to wall carpeting.
