The Ahuja PS-300TM 2-way compact PA wall speaker is engineered for versatile integration into commercial audio networks, supporting both high-voltage distributed line systems and low-impedance sound circuits. Its dual-mode operation makes it an adaptable component for system designers configuring background music and voice paging networks in commercial environments such as corporate offices, banks, retail showrooms, and hospitality venues.
100V Distributed Line Amplifier Compatibility
For large-scale multi-speaker installations, the Ahuja PS-300TM integrates natively with standard commercial 100V public address line amplifiers. In 100V distributed modes, line matching transformers allow multiple speaker units to be wired in parallel across extensive cable runs without severe line loss. Power draw per unit is determined by the rear-mounted rotary switch, which provides selectable wattage taps at 6W, 3W, and 1.5W. System integrators can balance sound pressure levels across distinct zones by adjusting tap values relative to the total amplifier wattage budget.
Low-Impedance (8-Ohm) Direct Amplifier Integration
The unit features a dedicated 8-Ohm (8Ω) operating mode selectable via the integrated rotary switch. When set to 8Ω, the speaker bypasses transformer stepping to interface directly with conventional low-impedance stereo amplifiers, mixer-amplifiers, or multi-zone commercial sound processors. In this mode, the 2-way transducer network—comprising a 75 mm (3-inch) woofer and 31 mm (1.22-inch) tweeter—handles 10W RMS (15W Max) power across a 150 Hz to 20,000 Hz frequency range, delivering clean acoustic dispersion at an efficiency rating of 86 dB SPL (1W/1m).
Electrical & System Compatibility Matrix
| Operational Mode | Input Specification | Power / Impedance Setting | Amplifier Output Requirement |
|---|---|---|---|
| 100V Distributed Line | 100V Line Audio | 6W Tap | Commercial 100V PA Output |
| 100V Distributed Line | 100V Line Audio | 3W Tap | Commercial 100V PA Output |
| 100V Distributed Line | 100V Line Audio | 1.5W Tap | Commercial 100V PA Output |
| Low-Impedance Direct | Direct Audio Signal | 8Ω (10W RMS / 15W Max) | 4Ω - 8Ω Low-Z Amplifier Output |
Mounting and Architectural Placement Compatibility
The speaker is supplied with an adjustable, movable mounting bracket that enables physical installation onto vertical walls, columns, or architectural bulkheads. The bracket design accommodates both vertical and horizontal mounting configurations, facilitating optimal acoustic alignment toward target listening zones. With compact enclosure dimensions of 105 mm (W) × 161 mm (H) × 119 mm (D) and a unit weight of approximately 1.04 kg, the housing easily integrates into structural partitions and standard wall frameworks without requiring heavy-duty structural reinforcement.
