Collection: Ultimax II

The Ultimax II Subwoofer Series by Dayton Audio is an evolution of the original Ultimax, offering enhanced performance and durability. With increased excursion, reinforced carbon fiber cones, and more robust voice coils, these subwoofers handle higher power and produce deeper, clearer bass. Improvements include dual spiders and stitched tinsel leads for greater stability and reliability, especially at high excursion levels. Extensive venting in the frame and motor enhances cooling, reducing heat buildup and power compression. Available in sizes from 8” to 18”, the Ultimax II series provides a powerful upgrade for audiophiles seeking next-level low-frequency performance.
