The Silverbird speakers are designed to provide an eminently versatile array of tones, retaining the distinct vintage character of their Reinforced AlNiCo ancestors, the Blackbird 40 speakers, but in a more affordable platform. Specific attention was paid to the top-end response, carefully tailored to make the Silverbird speakers well-suited to overdrive and high-gain applications. Additionally, they feature a more contemporary frequency curve on their respective treble ranges.

The Silverbird line utilizes a new 1 ½” (38mm) aluminum-wound voice coil with a Kapton former, designed to retain the trademark clarity of the Jensen clean tones, paired with a smooth, progressive contour of the top-end response; this response is tailored to grant openness with clean and pushed tones, and the necessary smoothness to keep the upper harmonics of the high-gain tones under control. The medium-sized Ceramic magnets provide the necessary strength for generous-yet-tight bass, while the new cone membranes, with a specific treatment on the paper surrounds, deliver a balanced response in the midrange and “presence” zone.

The Silverbird 10 has a more focused and present response with the typical immediacy of the best 10” speakers. Versatile enough to deliver an open, airy response in open-back cabinets, the Silverbird 10 can morph into powerful rock’n roll tone machines in closed-back enclosures.

Guitarist Description
Directly inspired from the Blackbird 10/40 tone, the Silverbird 10/50 is a superbly balanced speaker. Powerful bass range, tight enough for the higher gain applications, yet warm and full. Highly versatile, it fits nicely in a wide range of musical genres with its open and detailed vintage-inspired tone.
