The Ahuja PS-400T is a compact, 2-way high-fidelity wall speaker engineered for distributed sound reinforcement and background music (BGM) in commercial spaces. Designed with a 95 mm (3¾”) woofer, a 13 mm dome tweeter, and a weather-resistant white plastic cabinet measuring W133 × H187 × D (they are not included)107 mm, it provides balanced acoustic coverage across an 85 Hz to 20,000 Hz frequency range. The integrated rotary switch enables seamless configuration between 100V distributed line systems (tapped at 16W, 8W, or 4W) and direct 8-ohm low-impedance operation, supporting diverse architectural audio applications.
Corporate Offices and Commercial Workspaces
In modern office environments, meeting facilities, and reception areas, uniform acoustic distribution without visual clutter is critical. The PS-400T integrates cleanly against interior finishes due to its compact white enclosure. Facility managers can configure the rear rotary switch to lower 100V tap settings (such as 4W or 8W) to deliver non-intrusive background music and clear vocal announcements across open floor plans, corridors, executive suites, and boardrooms.
Banking Halls and Financial Service Branches
Financial institutions require dependable public address infrastructure for customer queue announcements, paging, and low-level ambient audio. Delivering an SPL sensitivity of 86 dB (1W/1m) and 16W RMS (24W Max) power handling, the PS-400T ensures vocal frequencies remain intelligible over background ambient noise. Its movable mounting bracket allows installers to aim the speaker precisely toward teller counters and customer waiting lounges in either vertical or horizontal orientations.
Retail Showrooms and Boutiques
Retail sales floors and brand showrooms require high-fidelity audio reproduction across the full 85–20,000 Hz spectrum to enhance customer experience. The dedicated 13 mm dome tweeter ensures crisp high-frequency detail, while the 95 mm woofer delivers solid mid-to-low acoustic presence. System integrators can mount units along perimeter walls or structural pillars, using horizontal or vertical bracket alignments to maintain clean sightlines.
Restaurants, Cafes, and Hospitality Venues
Dining rooms, hotel lobbies, and cafes benefit from the multi-tap 100V transformer design, allowing different volume zones within a single establishment. Dining areas can be set to 4W or 8W for subtle ambiance, while entrance vestibules or busier zones can be driven at the full 16W tap. The weather-resistant plastic cabinet also permits installation in semi-exposed or sheltered transitional spaces.
Direct Low-Impedance (8Ω) Sound Systems
Where constant-voltage 100V distribution is not required, the PS-400T can be switched directly to 8-ohm operation via its rear rotary dial. This allows system integrators to connect pairs of speakers directly to conventional low-impedance stereo amplifiers in executive cabins, presentation rooms, or compact retail counters requiring localized high-fidelity sound.
Application Matrix
