12″ Tone Tubby Humboldt Low Watt Alnico


The sexy, smoky combination of hemp at a lower power rating. Tight and focused, with early break-up. Just the ticket for rehearsals, garage jams, small cozy gigs, or in the studio. Perfect for lower power amps!

Tone Tubby speakers are the new sustainable standard for natural sound tonality and cone dependability. A luxury sound based on hard working technology. Tone Tubby delivers a consistently sweeter sound that many professional musicians rely on to optimize their recording sessions and live performances. From large amphitheater stage settings to intimate nightclub gatherings, you may have already experienced the Tone Tubby sound!

Made from natural and organic hemp fibers, Tone Tubby offers a rich and smooth sound unheard of from paper cone speakers. The cones are more durable with a heat and tear resistance unlike paper speakers. Cones made from hemp not only sound good, they are good for the environment. Using a renewable resource means fewer trees used for paper, more jobs and a more sustainable future.
