Consider the JBL A120. It's the smallest speaker in JBL's new Stage lineup, but it benefits from the company's long and rich history of making speakers. JBL paid particular attention to the design of the enclosure on these speakers, aiming to craft a non-resonant cabinet with rigid walls and internal bracing so that you hear your music and movies as they were meant to be heard. The 1" aluminium dome tweeter is mounted in an HDI (High Definition Imaging) waveguide that was designed for the JBL Professional M2 Master Reference Monitor. This flared shape helps smooth the transition from woofer to tweeter for a broad sweet spot and clear high-frequency detail. Each speaker's striking white 4-1/2" woofer is made of a stiff-but-lightweight polycellulose material to deliver solid bass for its size. A rear-panel port reinforces bass performance.
