The JBL Stage 240H Atmos Speakers are intended for Dolby Atmos or DTS:X systems. Notably, they fire upwards so can be used instead of built-in ceiling speakers.
Alternatively, they can also be mounted on the ceiling. The sealed enclosure houses a two-way unit with a 4.5” bass midrange driver and a 1” tweeter.
The frequency range is good for a compact speaker, extending from 85 Hz to 25 Hz. The maximum power handling is 150 watts.
The 4.5” bass/mid driver cone, as used in the JBL Stage 240H Atmos Speaker, is made of ribbed Polycellulose. Most speaker cones are made of a paper pulp known as cellulose. However, more modern materials are now being used. Polypropylene does not absorb moisture so maintains it’s properties better over time. Polypropylene can also produce less distortion.
Notably, the cone of the JBL Stage 240H Atmos Speaker is made of Polycellulose. This combines the best properties of cellulose and polypropylene. Namely, improved rigidity and damping characteristics. Lastly, the 1” anodized aluminium tweeter sits in a waveguide for improved high-frequency dispersion.
The cabinet of JBL Stage 240H Atmos Speakers is constructed of audio-grade MDF panels. Good internal bracing ensures resonance-free playback. Additionally, the sealed enclosure provides an accurate and detailed performance. The front grille protects the drivers and they can be wall or ceiling-mounted.
Two-way speakers such as the JBL Stage 240H Atmos Speakers need a crossover. The crossover splits the incoming audio into two components for feeding to the individual drivers. Audio-grade polypropylene capacitors are used as well as quality inductors.
The crossover acts as a high-pass filter. It feeds high frequencies to the tweeter. Good quality components are important as poor capacitors can go electrically leaky or change value over time.
The 240H Dolby Atmos enabled height modules are outfitted with the same woofer and horn from the 240B bookshelf model. They are easily connected via binding posts on the top back of both floorstanding models, or surround channels that can be mounted on the wall or ceiling.
Each speaker in the Stage 2 series features Polycellulose ribbed cone woofers. This pure pulp cone has a proprietary mix of other materials added to improve its rigidity and the ribs echo legendary JBL designs. These woofers produce deep, accurate, room filling bass.
Through intense research of previous waveguide designs, JBL has developed a new complex geometry that improves directivity, reduced diffraction, and an overall neutral frequency response both on and off axis. The Stage 2 HDI Horn is coupled to an anodized aluminum dome tweeter to enhance efficiency and dynamics. This new design offers a neutral frequency response both
