JBL Control 424LP - 2-Pack of 4-Inch Low-Profile Ceiling Speakers
The JBL Control 424LP is a high-performance in-ceiling speaker specifically designed to deliver exceptional sound quality in spaces where mounting depth is critical. This ultra-compact system, featuring a 4-inch (100 mm) woofer, integrates seamlessly into ceilings with shallow cavities, as its low-profile design requires less than 100 mm of clearance above the ceiling surface. This package includes two units, providing a complete solution for stereo installations or for covering larger areas with consistent sound.
Equipped with JBL's exclusive CRBI™ (Coplanar Radiation Boundary Integrator) technology, the Control 424LP guarantees exceptionally homogeneous sound coverage throughout the listening area. This innovative technology reduces volume inconsistencies and dead zones, ensuring that everyone in the room experiences clear, balanced audio. Its 130° conical coverage pattern is extremely wide, allowing for fewer speakers to cover the same space, optimizing both cost and aesthetics of the installation.
Versatility is one of its main strengths. Thanks to its 16-ohm nominal impedance, it's possible to connect up to four speakers in parallel to a single 4-ohm amplifier channel, significantly simplifying wiring and system design. Furthermore, it includes a high-quality 30W transformer for use in 70V or 100V distributed audio systems, with multiple power taps to suit any need.

Frequently Asked Questions
- Does this item include one or two speakers?
- This product is supplied in a package containing two (2) units of the JBL Control 424LP speaker, along with their corresponding grilles and mounting accessories.
- Is it possible to paint the grille?
- Yes, the frameless magnetic grille is designed to be painted and customized to match the ceiling color. The package includes a paint protector to cover the speaker components during the painting process.
- What advantage does its 16 ohm impedance offer?
- A 16-ohm impedance allows up to four Control 424LP speakers to be connected in parallel to a single amplifier channel stable at 4 ohms. This simplifies wiring and optimizes amplifier use in low-impedance installations.
- Are they suitable for environments with some humidity, such as a bathroom?
- The speaker has an IP33 rating, meaning it's protected against splashing water. It's suitable for areas like bathrooms or covered porches, but shouldn't be exposed directly to rain or water jets.
