12" Blackbird 40

A new take on the classic AlNiCo tone, with a bolder voice for vintage and modern players

Jensen Loudspeakers is pleased to announce the release of the Jensen Blackbird 40, a new 12” guitar speaker in the Jet Series. The Blackbird 40 is a 40W speaker with a 1.26 inch copper-wound voice coil and a reinforced AlNiCo magnet in the classic “horseshoe” format.

Development of the Blackbird 40 focused on achieving two different goals. The first was to capture the classic vintage character and chime, in order to resemble the tone of one of the most popular Jensen Speakers ever, the P12Q. Second was to offer a significantly increased sensitivity and a stronger magnet to achieve a firmer and more powerful bass response. These characteristics make the Blackbird 40 perfectly suited for more modern applications, including those requiring higher gain and overdriven tones.

The Blackbird 40 is the first speaker in the Jet Series featuring Jensen’s exclusive Reinforced AlNico magnet technology. This new technology results in a magnet which has been reinforced and made more efficient, raising the overall Flux Density (the “strength” of the magnet) by over 30%. This results in the behavior of a much bigger and more expensive magnet without the added cost.

The outcome is that the Blackbird 40 delivers all the classic, unmistakable voice of a Jensen AlNiCo speaker, supported by a stronger, firmer foundation that reinforces the bass range. The Blackbird 40 is great for an upgrade to a classic vintage amplifier, yet is equally suited to modern, more versatile amplifiers.
