Audison is proud to introduce the LRx ABD Class models, overcoming the huge challenges associated with car audio: LRx 5.1k and LRx 3.1k are the first two models to offer “A Class Biased” channels to drive the detailed high frequency section, AB class channels to drive the dynamic woofer section combined with the highly efficient auD-class technology for the high output subwoofer section, all in the same heatsink.
The 3-channel LRx 3.1k offers the same stunning capabilities as LRx 5.1k, for a two-way plus subwoofer design.
