Easy Installation
Less narrow ‘beaming’ of higher tones occurs because the enhanced filtering creates bigger vertical opening angles for high frequencies. This line array has a more consistent opening angle throughout all key frequencies when compared to traditional column loudspeakers. For instance, the vertical opening angle is still 18° at 4 kHz.
Installation is made simpler by more consistent vertical opening angles since a larger coverage area means that loudspeaker location is less important. With a superior horizontal opening angle of 90° at 4 kHz, a single loudspeaker can reproduce genuine sound across a large listening area.

Suppressed Side Lobes
Every traditional column loudspeaker emits many unwelcome side lobes in addition to the primary, listener-facing lobe of sound.
The LBC Line Array 3210/00 Loudspeaker produces significantly cleaner, less “colored” sound, even up near to the loudspeakers, because of its strongly suppressed side lobes in the vertical plane, which are normally at least 10 dB from the 250 Hz octave band at 90°. This results in excellent voice and music intelligibility from the line array speakers.

LC3-UC06 – Ceiling loudspeaker, 6W
The LC3-UC06 Ceiling loudspeaker is an affordable, all-purpose 6 W ceiling loudspeaker that may be powered by 3, 6, or 1.5 Watts and is compatible with a 100 V supply.
Key features
- Suitable for speech and music reproduction
- Lightweight ABS material
- Easy to install
- Optional back-box
- Unobtrusive design
A low impedance (4 Ohm) variant of the ceiling loudspeaker, the LC3-UC06-LZ, may be connected directly to the output of a low impedance amplifier.
The optional back-box LC3-CBB completely shields the loudspeaker from dust and falling items, and it also stops sound from entering adjacent spaces through the ceiling hollow.
As per UL 94V0, the LC3-UC06 Ceiling loudspeaker frame, grill, and back-box are made of self-extinguishing ABS.
Installation
With built-in spring arms that firmly hold the ceiling loudspeaker in its cut-out, installation is simple. Ceilings ranging in thickness from 5 to 25 mm are compatible. Additionally, a template for precisely outlining the cut-out in ceiling panels is given.
Flying leads are used for the electrical connection, with each hue linked to a separate primary tap on the corresponding transformer. The matching transformer has three primary taps for 100 V, allowing for the selection of nominal full, half, and quarter power.
The optional back-box (LC3-CBB) keeps the loudspeaker safe from dust and falling debris, makes it pest-proof, and stops sound from entering adjacent spaces through the ceiling hollow.

Certification
The LC3-UC06 Ceiling loudspeaker is built to meet IEC 268‑5 Power Handling Capacity (PHC) specifications, which require them to operate at full power for 100 consecutive hours.
Bosch has furthermore created the Simulated Acoustical Feedback Exposure (SAFE) test to show that, for brief periods of time, they can tolerate two times the power that is rated for them.
This guarantees enhanced dependability in harsh circumstances, resulting in increased customer satisfaction, an extended operational lifespan, and a decreased likelihood of malfunction or decline in performance.
