The CALI424 is a 2-way ceiling speaker with rear dome, constructed using a 4” cone driver, combined with an coaxially mounted 1” soft dome tweeter which is fitted with a phase plug for excellent off axis performance up to 155°.

The 2-way construction combination with metal rear-dome guarantees premium performance for demanding applications. A continuous power handling of 30 Watt (RMS) and maximum power handling of 60 watt is achieved, while fitted with a rotary switch for tapping of the 70/100V line transformer with tappings for 24W, 12W, 6W and an 8 Ohm bypass connection.

Improved acoustical performance
Crystal clear sound

Improved acoustical performance

With the introduction of the CALIxI variants, we have re-engineered both the drivers and the internal filter (crossover) to achieve superior acoustical performance. A significant leap forward compared to its predecessor, resulting in an enriched and immersive audio experience.

Enhanced installation
Installation becomes a breeze

Enhanced installation

Together with the unique SafeLatch™ innovation, quick and easy connection can be done through a ‘swivel’ lid with conduit clamp, this had a rotating lid design which is reminiscent of market standards. A pluggable terminal block connector simplifies the installation process, decreases the installation time and ensures a secure connection for seamless operation.

Borderless grill design
TwistFix™ technology

Borderless grill design

The TwistFix™ system assembles the speakers’ grill through twisting. A bajonet type locking with lips on the grill side gets fixed through insertion to slots on the speakers housing and giving it a partial turn. This system guarantees lifetime stable mounting while fixation can be done in a record-breaking time.

Shallow built-in depth
A wide range of applications

Shallow built-in depth

These ceiling speakers have a mounting very shallow built-in depth of only 120 mm (max.), making them perfect for suspended ceilings, hollow walls and many more applications.

Suited for 70/100V applications
Multi-tapping line transformer

Suited for 70/100V applications

Fitted with a rotary switch for tapping of the 70/100V line transformer with tappings for various connections. This makes the speaker the ideal solution for your project.
