Audibax LA05-T - 4.5” Recessed Ceiling Speaker for 100V Line (White)

The Audibax LA05-T is a recessed ceiling speaker designed for 100V line sound systems . It features a 4.5” woofer in a 1-way configuration and a transformer with selectable 1.5W / 3W / 6W taps , allowing for easy power adjustment per zone without overloading the amplifier. Its ABS construction with a metal grille ensures durability and a discreet finish. With an outer diameter of 170 mm , a cutout of 150 mm , and a depth of 58 mm , it integrates quickly into plasterboard or suspended ceilings using mounting brackets . It offers a frequency response of 150 Hz–20 kHz and an SPL of 91 dB , providing clear intelligibility for background music and announcements in retail, hospitality, and office settings.

Main features

Frequently Asked Questions

• How do I select the power (1.5/3/6 W)? Use the selector on the speaker transformer before mounting it to the ceiling. Adjust the power supply according to the required level for each zone.
• What is the cutting diameter? 150 mm . Use the cutting template and check that there are no pipes behind the panel.
• Is it suitable for outdoor or humid areas? No. It has an IP20 rating , meaning it's only suitable for dry indoor use.
• Can I use it with low-impedance amplifiers? It's an 8 Ω speaker with a 100V transformer. For low-impedance use, follow the manufacturer's instructions and good installation practices.

Installation and recommendations

• Mark the 150 mm cut with the template and check for clearance behind the roof.
• Connect respecting polarity; select the 1.5/3/6 W socket according to the coverage design.
• Secure the clamping claws without exceeding the tightening torque to avoid deforming the roof.
• Maintain separation from noise sources (HVAC) to preserve intelligibility.
