About the Ultra-X13: DISCONTINUED
The Outlaw Audio Ultra-X13 is a discontinued legacy powered subwoofer designed for high-output, low-distortion home theater and music playback. It was Outlaw Audio’s most advanced subwoofer and was engineered to meet THX Ultra requirements, with reference-level output up to 115 dB SPL in the certified configuration. The design uses a down-firing 13-inch long-throw woofer, dual ports with foam plugs for sealed or ported operation, and an internal DSP-controlled 1000-watt amplifier system. The product page identifies it as discontinued and kept only for historical/archival purposes.
