About: B2 Audio Zero9 The Osprey Amplifier

When the Zero series was first released in 2010, it was hailed as a revolution in car audio. Their power, performance, and reliability were unmatched. The Zero series are amplifiers that have set multiple world records and secured championships all over the world. In their time, they were the benchmark to compare with. Not only in terms of performance, but even appearance. B2 decided to merge the DNA and heritage of the Zero series amplifiers and to build with the technology of the future. The B2 Audio Zero series amplifiers are a statement of quality both in design and in the components used. Sourced from all over the world and not accepting anything other than the best, they boast amazing power ratings, but offer reliability and a sense of pride in ownership, rarely seen in this era.

In regards to the Zero 8 the amplifier was entirely redesigned. B2 Audio opted for a small performance increase along with improved and efficient cooling system modes, while also adding simple gain matching features. With all these changes, the Zero 8 evolved into the new Zero 9 model.
