REL Tzero MKIII Powered Subwoofer for Small Room The Tzero MKIII packs the signature REL sound into a compact, affordable subwoofer that enriches smaller systems with powerful, natural bass. Built with a new aluminum cone for strength and punch, plus a high-efficiency Class D amp, it delivers deep bass in limited spaces like apartments or studies. Design Precision With high gloss black or white lacquer, the Tzero MKIII also includes REL†s renowned High-Level Input, separate .1/LFE input, and a fast 8ms filter.
Ideal for smaller rooms, it performs like a true REL—powerful, controlled, and crafted to deliver satisfying bass without dominating the space. Miracle in Miniature Designed around a robust 6.5†driver, the Tzero MKIII exceeds its size with deep, articulate bass for small to medium rooms. For larger spaces, consider one of our larger models or use multiple Tzeros to fill your space with immersive sound.
