Tone Tubby Key West Alnico 12" Hemp Cone Guitar Speaker
30 Watt     8 ohm  

Tone Tubby developed a new low profile Alnico speaker that fits inside amps with tight speaker spacing.
Compact guitar amps can now enjoy the relaxed musical voicing of vintage Alnico with Hempcone texture and tonal balance.
The magnet's tighter field around the voice coil also adds more efficient power handling.

The Key West model shares the same standard hempcone with the Chicago Blue.
If you desired a Chicago Blue for your compact amp, you got it now with added power handling.

Standard Alnico speaker height: 6-1/2"

Low Profile Alnico speaker height: 5-3/16"

Hemp is the name of the fiber that is cultivated from plants of the Cannabis genus. Hemp has been used for industrial purposes including paper, textiles, biodegradable plastics, construction, health food and fuel.
Hemp fiber used for speaker cones provides a durable, tear resistant and water resistant cone. The long fiber of hemp provides better sound reproduction and longer sound waves.
Hemp vs. Paper

Hempcone® speakers deliver an organic and natural sound. By using hemp fibers instead of paper, the hemp cone delivers a consistently sweeter sound that many professional musicians rely on to optimize their recording sessions and live performances.

Paper cones will dry out, become brittle and give a brittle tone. Hemp provides a rich, full spectrum of tone from a cone that is stronger and more flexible.

Ceramic vs. Alnico

Alnico is an iron alloy which in addition to iron is composed primarily of aluminium (Al), nickel (Ni) and cobalt (Co), hence al-ni-co, with the addition of copper, and sometimes titanium. Alnico is inherently a warmer and smoother tone.

Ceramic (ferrite) magnets are composed of strontium carbonate and iron oxide. Ceramic magnets tend to produce a brighter, edgier tone and work great in 4x12 sealed back cabinets.

Alloy magnets like Alnico have an immediate and temporary demagnetizing reaction to the moving voice coil, lending a smooth compression effect to the signal that feels lively and responsive.
Ceramic magnets demagnetize less readily and sound edgier and punchier.
