JBL Professional C426LP - Low Profile Ceiling Speaker (2 Pack)
The JBL Control 426LP is a high-performance coaxial ceiling speaker, specifically designed to overcome installation challenges in spaces with shallow ceilings. This two-unit package offers a professional, compact, and aesthetically discreet audio solution, ideal for a wide variety of commercial applications. Its ultra-low-profile enclosure, less than 100 mm deep, allows for mounting in locations where conventional ceiling speakers wouldn't fit, without compromising JBL's legendary sound quality.
At the heart of the Control 426LP is JBL's exclusive CRBI™ (Coplanar Radiation Boundary Integrator) technology. This innovative design integrates high and low frequency components into a single plane, resulting in exceptionally smooth and even sound dispersion throughout the listening area. Its wide 110° conical coverage enables consistent audio distribution, reducing the number of speakers needed to cover a space and eliminating sound variations between different zones. The result is a clear, intelligible, and immersive listening experience for everyone.
With a nominal impedance of 12 ohms, it offers installers great flexibility, allowing up to three speakers to be connected in parallel to a single 4-ohm amplifier channel. It also includes a high-quality 60W transformer for use in 70V or 100V distributed audio systems, with multiple power taps to suit the needs of any project.
Main Features
-
Low Profile Design: With a mounting depth of less than 100 mm, it is the perfect solution for ceilings with reduced plenum, beams or other obstructions.
-
Superior Acoustic Performance: Equipped with a 6.5-inch (165mm) treated paper cone woofer and a 1-inch (25mm) soft dome tweeter that provide a balanced and natural frequency response.
-
Exclusive JBL CRBI™ Technology: Ensures wide and uniform 110° coverage, optimizing voice intelligibility and music clarity throughout the space.
-
Flexible Installation: Its 12-ohm impedance facilitates parallel connection. It also features an integrated transformer for 70V and 100V line systems with multiple power outlets (60W, 30W, 15W, 7.5W).
-
Discreet and Modern Aesthetics: The frameless magnetic grid blends seamlessly into any décor. It can be painted to match the ceiling color, achieving an almost invisible appearance.
-
Reliability and Protection: Incorporates an overload protection circuit with a PTC limiter to ensure a long service life and safe operation, even at high volume levels.
-
Professional Certifications: Meets the strict safety standards UL1480A and UL2043 for use in air handling spaces, plus RoHS2 and IP33 environmental certifications.
Benefits for the Installer and the Listener
For the professional installer, the Control 426LP simplifies the job thanks to its low-profile design, easy-to-mount magnetic grille, and compatibility with multiple types of amplification systems. For the listener, the advantage is high-fidelity, clear, and evenly distributed sound, without the "hot spots" or "dead zones" often found in lower-quality ceiling sound systems. Speech intelligibility is exceptional, making announcements and background music sound crystal clear.
Use Cases
This speaker is the ideal choice for a wide variety of commercial and public environments where ceiling space is limited but sound quality cannot be compromised. Its performance makes it perfect for:
- Shops and retail businesses
- Restaurants, cafes and bars
- Hotel lobbies and corridors
- Offices and conference rooms
- Waiting rooms and medical centers
- Airports and transport terminals
- Public address and background music systems
For applications requiring greater low-frequency response, it can be perfectly complemented with JBL ceiling subwoofers, such as the Control 419CS/T.
Frequently Asked Questions
What does "low profile" mean and why is it important?
This means the speaker's overall depth is very shallow (less than 10 cm). This is crucial for installations in ceilings with limited clearance due to beams, air conditioning ducts, or other structures, allowing for professional installation where other speakers wouldn't fit.
What is JBL's CRBI™ technology?
Coplanar Radiation Boundary Integrator (CRBI™) technology is a JBL-patented waveguide design that mounts the tweeter in the same plane as the woofer. This aligns the acoustic centers of both drivers, resulting in a much smoother frequency transition and wider, more uniform sound coverage throughout the listening area.
Can I paint the grate to match my decor?
Yes, the frameless magnetic grille is designed to be painted. The package includes a paint protector to cover the speakers while the grille is being painted, ensuring a seamless aesthetic integration with any ceiling.
Do I need a special amplifier for these speakers?
Not necessarily. Thanks to their 12-ohm impedance and integrated transformer, they are compatible with most professional amplifiers. They can be used in both low-impedance systems (connecting up to three in parallel on a 4-ohm channel) and 70V or 100V line systems, which are very common in commercial installations.
What's included in the package?
The package includes two Control 426LP speakers, two magnetic grilles, two C-ring anchor brackets, two ceiling tile rails, a cutting template, and a paint protector.
