Specifications Top

The AL line of Audible Physics drivers is truly a testament to proper speaker design. The AL line is named with respect to the aluminum-alloy used for the cone, a material that is both lightweight and rigid. This provides the 425-AL the ability to play high-frequencies accurately. The 425-AL is also able to play lower frequencies (down to 70 Hz) with authority. The versatility of this 4" gives it the ability to be used either as a midrange, or as a fullrange driver in on-axis applications.

For many years, Audible Physics have been designing and being the Original Equipment Manufacturer of world class loud speaker drivers for many home audio companies. They discovered the niche in the high fidelity miniature loudspeaker drivers. In 2009, Audible Physics and began producing speaker drivers under their own name, and with one of the highest quality standards in the industry. In 2016, they had chosen MCM Electronics to be the official distributor of their home audio products in North America.
