Exceptional Midrange/woofer
5.7 inch woofer with a 2 inch diameter long throw voice coil using a high powered motor allowing for smooth air flow melds seamlessly into the ribbon tweeter thanks to its low mass and high speed, while performing incredible feats in bass response thanks to the Alta XTL bass tuning system.

What is Alta XTL?
XTL stands for Extended Transmission Line, an Alta Audio proprietary technology used in our speakers. We developed XTL using specialized sonic geometry to tune our cabinets like musical instruments, allowing all our speakers to deliver unprecedented clear, fast, and powerful bass.

Standard transmission lines can make the bass slow and distorted. The difference between Alta XTL and a standard transmission line is that we tune the cabinet at multiple frequencies, not just one. Think of it like a cello amplifying and extending the notes played off the strings. Our cabinets are tuned to extend the bass of a driver, giving a clean fast bass response that is in a different class than standard transmission line designs. Coupled with our DampHard technology, Alta XTL shines to create a clear and musical extended resonance free cabinet.
