Description
Add clear background music and voice paging to restaurants, retail stores, offices and covered commercial patios with a compact wall-mounted speaker designed for flexible 70V, 100V and 8-ohm systems.
The TEXONIC CS74B is a black 4-inch two-way commercial wall speaker designed for background music, paging and general announcements. Its built-in transformer supports 70V and 100V distributed audio systems, while the selectable 8-ohm mode allows connection to a compatible low-impedance amplifier. An adjustable mounting bracket supports vertical or horizontal installation on walls, columns and suitable open-ceiling structures.
TEXONIC CS74B Commercial Wall Speaker
The CS74B combines a compact ABS enclosure, steel grille, two-way speaker system, commercial audio transformer, rear tap selector and adjustable mounting bracket in one surface-mount speaker.
It is a practical choice where recessed ceiling speakers are not suitable or where the sound needs to be aimed toward a specific seating, customer or working area.
Brand: TEXONIC
Model: CS74B
Speaker design: Compact two-way wall speaker
System compatibility: 70V, 100V or 8Ω
Finish: Black
Selling unit: One speaker with mounting bracket
Two-Way Sound for Music and Paging
A 4-inch main driver reproduces voice, music and midrange content, while a separate 1.5-inch high-frequency driver improves vocal clarity and music detail.
This two-way design provides more balanced sound than a basic single-cone paging speaker. It is suitable for businesses that use the same audio system for everyday background music and occasional announcements.
Compact Sound for Small and Medium Commercial Areas
The CS74B is designed for clear speech and comfortable low-to-moderate background music in areas where a compact speaker is preferred.
For deep bass, high-volume foreground music or demanding entertainment applications, consider a larger commercial wall speaker or add a compatible commercial subwoofer.
Wide 120° Sound Coverage
The published 120-degree sound coverage helps distribute music and speech across a broad listening area.
The adjustable bracket allows the speaker to be aimed toward tables, customer areas, reception desks, hallways, workspaces or other occupied sections instead of directing sound toward an unused wall or ceiling.
Recommended Commercial Applications
| Business Type | Typical Use |
|---|---|
| Restaurant or Café | Dining-room music, covered-patio audio and staff paging |
| Retail Store or Showroom | Customer-facing music, promotions and announcements |
| Office or Reception Area | Background music, paging and general presentation audio |
| Hotel or Hospitality Space | Lobby, corridor, lounge and meeting-area sound |
| Clinic, Salon or Spa | Ambient music and clear general announcements |
| School or Training Facility | Classroom audio, program sound and voice paging |
| Open-Ceiling Commercial Space | Surface-mounted sound where recessed speakers are impractical |
70V and 100V Commercial Audio Compatibility
The transformer built into the CS74B allows several speakers to connect to a compatible 70V or 100V commercial amplifier.
Constant-voltage systems are useful for multi-speaker installations and longer cable runs. The speakers connect electrically in parallel, and the selected transformer taps are added together to calculate the total amplifier load.
Selectable Transformer Taps
| Speaker-Line Voltage | Available Settings |
|---|---|
| 70V | 1.25W / 2.5W / 5W / 10W / 20W |
| 100V | 2.5W / 5W / 10W / 20W |
| Low Impedance | 8Ω mode |
Use only the tap values identified for the amplifier’s actual speaker-line voltage.
The 1.25W setting is available for 70V operation only. The lowest published 100V setting is 2.5W.
Choosing a Transformer Tap
| Tap Range | General Application |
|---|---|
| 1.25W–2.5W | Quiet offices, hallways and low-level ambient sound |
| 5W | General office, retail and hospitality background music |
| 10W | Restaurants, showrooms and moderate background noise |
| 20W | Larger or noisier areas requiring stronger output |
These are general planning examples. Final selection depends on speaker quantity, mounting height, room acoustics, background noise, listening distance and the required sound level.
Speaker-Load and Amplifier Examples
Add the selected transformer tap of every speaker connected to the commercial amplifier. Leave practical operating capacity rather than loading the amplifier to its full rating.
| Speaker Configuration | Total Load | Practical Amplifier Size |
|---|---|---|
| 4 speakers at 5W | 20W | 30W or higher |
| 4 speakers at 10W | 40W | 60W or higher |
| 6 speakers at 10W | 60W | 120W or higher |
| 8 speakers at 10W | 80W | 120W or higher |
| 8 speakers at 20W | 160W | 240W or higher |
| 12 speakers at 10W | 120W | 240W or higher |
Maintain Amplifier Headroom
For practical commercial-audio planning, keep approximately 20% of the amplifier’s rated output available as operating reserve.
| Amplifier Rating | Recommended Maximum Tap Load |
|---|---|
| 30W | Approximately 24W |
| 60W | Approximately 48W |
| 120W | Approximately 96W |
| 240W | Approximately 192W |
Different Tap Settings in One System
Speakers connected to the same 70V or 100V line may use different transformer taps.
A quiet hallway may use 2.5W while speakers in a busy customer area use 10W. Add each selected tap separately when calculating the final amplifier load.
8Ω Low-Impedance Operation
The rear selector provides an 8-ohm operating position for use with a compatible low-impedance amplifier.
The current AVTECK listing identifies the speaker as 30W RMS and 60W peak in 8Ω operation. One speaker presents an 8-ohm nominal load. Two speakers connected in parallel create a 4-ohm load.
Never connect the speaker to a 70V or 100V amplifier output while its selector is set to 8Ω. Low-impedance and constant-voltage calculations must not be mixed.
Parallel and Daisy-Chain Wiring
In a 70V or 100V system, multiple CS74B speakers are connected electrically in parallel. The cable may physically run from the amplifier to one speaker and continue to the remaining speakers.
- Connect every speaker to the same 70V or 100V speaker line.
- Keep positive and common polarity consistent throughout the run.
- Select the correct tap on every speaker before operating the system.
- Add all selected tap values when calculating the amplifier load.
- Use speaker cable approved for the building and installation area.
- Switch off the amplifier before wiring or changing tap settings.
Important Connection Warning
Select the correct 70V, 100V or 8Ω operating mode before switching on the amplifier.
Do not use a 70V-only tap value with a 100V amplifier output.
Do not connect a speaker set to 8Ω to a 70V or 100V output.
Do not connect different amplifier output types to the same speaker line.
Power down and disconnect the amplifier before wiring speakers or adjusting the rear selector.
Horizontal or Vertical Mounting
The included U-shaped mounting bracket allows the CS74B to be installed horizontally or vertically on a suitable wall, column, beam or open-ceiling structure.
After installation, the speaker can be angled toward the intended listening area. This provides more directional control than a fixed flush-mounted ceiling speaker.
Indoor and Protected Covered-Outdoor Use
The CS74B may be used indoors or in a protected covered-outdoor area such as a roofed patio, sheltered entrance or covered service area.
A published IP weather rating is not listed. Do not install the speaker where it will be directly exposed to rain, snow, water spray, standing moisture or severe weather.
Durable Commercial Construction
- Compact black ABS enclosure
- Protective steel front grille
- Adjustable U-shaped mounting bracket
- Rear 70V, 100V and 8Ω selector
- Gold-plated connection terminals
- Horizontal or vertical mounting
Installation Planning
- Confirm that the wall or structure can support the speaker and bracket.
- Use screws, bolts or anchors rated for the mounting surface.
- Check for electrical wiring, plumbing and HVAC components before drilling.
- Aim the speaker toward occupied areas rather than reflective walls or glass.
- Distribute multiple speakers evenly instead of placing them in one area.
- Follow applicable building, electrical and installation requirements.
Surface-specific screws, bolts and wall anchors are not included. Select suitable mounting hardware for the wall material and structural conditions.
