The Ahuja SP-6305TD 30W RMS PA dual sound projector is engineered specifically for commercial and industrial acoustic installations requiring efficient, bi-directional sound distribution along extended linear zones. Built with two opposite-facing 16.51 cm (6.5-inch) full-range water-resistant cone speakers within a rugged white ABS plastic enclosure, this projector speaker minimizes unit count while providing uniform sound pressure level (94 dB at 1W/1m) and clear vocal reproduction across 120 Hz to 15,000 Hz.
Railway Platforms and Transit Hubs
In railway stations, metro platforms, and passenger concourses, acoustic intelligibility must overcome continuous ambient noise while covering long, narrow thoroughfares. The SP-6305TD projects sound simultaneously in two opposite directions, providing clear emergency broadcasts, automated route announcements, and passenger information across platforms. Its IP-44 ingress protection rating safeguards internal components against particulate dust and splashing water generated in semi-exposed rail environments.
Industrial Plants, Warehouses, and Factory Gangways
Manufacturing floors, packaging lines, and logistics warehouses frequently feature extended aisles and high ceilings flanked by machinery. Using standard single-direction horns in these environments often leads to excessive reverberation and requires high speaker density. The SP-6305TD is deployed along central aisles and overhead crane gantries via its robust 'U' type mounting bracket, delivering balanced bi-directional coverage to operators along both travel directions of the gangway on 100V line distribution systems.
Multi-Level Parking Garages and Covered Perimeter Walkways
Concrete parking structures, drive aisles, and perimeter security walkways present challenging acoustic conditions with high dampness and vehicular exhaust. The weather-resistant white ABS housing resists structural degradation, while the multi-tap transformer (configurable to 30W, 20W, 10W, or 5W on 100V lines) allows system integrators to balance audio levels across drive lanes, pedestrian paths, and ramp junctions without overloading amplifier circuits.
School Corridors and Institutional Hallways
Educational facilities, hospitals, and corporate campuses require clear public address and emergency bell signaling along interconnected corridors. The compact Ø175 mm × H256 mm cylindrical profile mounts cleanly to corridor ceilings, projecting synchronized audio down both ends of the hallway. Tapping at lower wattages (such as 5W or 10W via external color-coded leads) provides gentle, highly intelligible background paging without acoustic harshness.
Theme Parks, Boardwalks, and Outdoor Walkways
In commercial recreational venues, theme parks, and pedestrian zones, the SP-6305TD provides dual-direction background music and public announcements along paths and landscaped perimeter zones. The 2.60 kg unit integrates seamlessly into 70V/100V high-impedance commercial audio infrastructure, allowing long cable runs with negligible line loss across distributed outdoor installations.
Application Suitability Matrix
- Railway Platforms & Metro Stations: Bi-directional announcements across long waiting tracks; IP-44 dust/water resistance.
- Factory & Logistics Aisles: 30W high-output paging down industrial racking corridors with 94 dB sensitivity.
- Parking Garages & Ramps: Tough ABS enclosure with external lead impedance selection (330Ω to 2kΩ).
- Institutional Corridors: Efficient dual-ended speech reproduction reducing ceiling speaker hardware requirements.
