Audibax CS5T - 5.25" Recessed Ceiling Speaker 40 W RMS, 8 Ω / 70–100 V

Audibax CS5T - 5.25" Recessed Ceiling Speaker 40 W RMS, 8 Ω / 70–100 V

The Audibax CS5T is a round, two-way passive in-ceiling loudspeaker designed to deliver high intelligibility and balanced musical sound in distributed audio projects. It features a 5.25" (≈133 mm) fiberglass woofer and a 0.75" (19 mm) titanium dome tweeter , with a frequency response of 70 Hz to 20 kHz and a sensitivity of 90 dB (1W/1 m) . Its dual operating modes allow connection in low impedance (8 Ω) or 70/100 V line mode via selectable taps of 3.75 / 7.5 / 15 W , simplifying integration into new or existing systems. It delivers 40 W RMS in low impedance mode and a maximum SPL of 40 W RMS . With 100 dB noise reduction and a wide dispersion of 151° × 151° , it evenly covers small and medium-sized rooms. The set includes a grille , Euroblock and screw connections, and an ABS housing for quick, reliable, and aesthetically pleasing installation.

Product benefits

• Total versatility: compatible with low impedance and constant voltage (70/100 V) systems, ideal for both expansions and new installations.
• Clarity and detail: combination of fiberglass cone and titanium dome for crisp vocals and balanced ambient music.
• Homogeneous coverage: its 151° × 151° dispersion reduces the number of installation points to cover the same area.
• Quick installation: cutting template included and Euroblock terminals + screw for clean and safe assembly.
• Discreet aesthetics: low-profile circular grid design that blends into all types of ceilings.

Use cases

• Commercial and retail: stores, supermarkets, showrooms and large stores.
• Hospitality: hotels, cafes, restaurants and waiting rooms.
• Education and offices: classrooms, hallways, meeting rooms and common areas.
• Sports and wellness centers: gyms, spas and lobbies.

Frequently Asked Questions

• Should I use 8 Ω or 70/100 V? Use 8 Ω for independent zones with a conventional amplifier; choose 70/100 V when you need long runs and several units per line, selecting the tap (3.75 / 7.5 / 15 W) according to the available power.
• What size cutout do I need? Ø 179 mm . Check that the false ceiling has at least 80 mm of free depth for installation.
• What type of wiring is recommended? At 70/100 V, 1.5–2.5 mm² cross-sections to minimize losses in long lines; at 8 Ω, 2.5 mm² if the route exceeds 10–15 m.
• Does it include a grid? Yes, the grid is supplied along with the cutting template and the manual.

Installation tips

• Respect the cutting template and ensure the fixing on solid surfaces of the false ceiling.
• In line 70/100 V, add up the taps of all the speakers in the branch and select an amplifier with a margin ≥20% over the total.
• Distribute the units seeking smooth overlaps between coverage areas (151° × 151°) to maintain uniformity and avoid hot spots.
