Ahuja PS-400TM Wired 16 Watt White PA Wall Speaker in Bangladesh

For businesses, offices, educational institutions, restaurants, banks, showrooms, and other commercial environments, installing a suitable PA speaker is about much more than simply making sound louder. The speaker needs to provide understandable announcements, consistent background music, convenient installation, and compatibility with the amplifier or distributed audio system. The Ahuja PS-400TM addresses these requirements through a practical two-way design and flexible connection options.

Its 100V line capability is particularly useful for distributed public address systems. The selectable power taps allow the installer to choose between 16W, 8W, and 4W operation depending on the requirements of the installation. At the same time, the speaker can be used as an 8Ω low-impedance speaker, giving it additional flexibility for compatible amplifier configurations.

Two-Way Audio Design

One of the defining characteristics of the Ahuja PS-400TM is its two-way speaker configuration. Instead of relying on a single driver to reproduce the entire audible range, the speaker uses a dedicated woofer and dome tweeter.

The 93mm, or approximately 3.6-inch, woofer handles the lower and midrange portions of the audio spectrum, while the 47mm, or approximately 1.85-inch, dome tweeter is designed to reproduce higher frequencies. This division of responsibilities allows the PS-400TM to provide a more balanced presentation for both speech and music.

For a PA installation, this matters because the speaker may be required to reproduce different types of content throughout the day. A shop may use it for background music and customer announcements. An office may use it for voice communication and general audio. A restaurant may require music playback while also making announcements.

The two-way architecture gives the PS-400TM the flexibility to serve these different purposes from one compact wall-mounted enclosure.

16W RMS Power for Distributed Audio

The PS-400TM is rated at 16W RMS, with a maximum power rating of 24W according to Ahuja's official specification. RMS power is particularly useful when evaluating speakers for continuous audio applications because it provides a more meaningful indication of sustained power handling than a maximum or peak figure alone.

Sixteen watts may appear modest compared with high-powered entertainment speakers, but a PA wall speaker serves a different purpose. In a distributed audio system, multiple speakers can be positioned around a building or venue so that sound is delivered more evenly throughout the required area.

This approach can be more practical than trying to use a single extremely powerful speaker to cover an entire space. Multiple appropriately positioned PA speakers can help maintain consistent listening levels while reducing the need to push one speaker excessively hard.

The PS-400TM is therefore well suited to applications where clear and distributed audio is more important than extremely high-volume entertainment playback.

100V Line PA Compatibility

The 100V line capability is one of the most important features of the Ahuja PS-400TM. It is designed as a 100V multi-purpose PA wall speaker and provides selectable power taps of 16W, 8W, and 4W.

100V line audio systems are widely used in distributed sound installations because they allow multiple speakers to be connected over suitable cable runs with relatively straightforward system design. The amplifier and speaker configuration must, of course, be properly matched by the installer.

The selectable power taps provide additional control over how much power the individual speaker draws from the 100V line system. An installer can choose 16W when greater output is required, 8W for a moderate setting, or 4W when lower power is appropriate.

This makes the PS-400TM useful for installations where different areas may have different sound-level requirements.

Rotary Power Selection

The power taps are selectable through a rotary switch. This gives installers a convenient way to configure the speaker for the desired 100V operating level without requiring a completely different speaker model.

This flexibility can be valuable during system installation. For example, a speaker installed in a relatively quiet office area may not need the same power setting as one installed in a busier showroom or restaurant.

Instead of purchasing different speakers for every location, the installer can configure compatible PS-400TM units according to the requirements of each zone.

8Ω Low-Impedance Operation

In addition to its 100V line functionality, the Ahuja PS-400TM provides an 8Ω low-impedance operating option.

This gives the speaker another connection method when paired with a compatible amplifier. It is important to distinguish this from the 100V line configuration because the amplifier output and wiring arrangement must match the selected speaker mode.

For professional installations, this dual compatibility can make the PS-400TM more versatile than a speaker designed exclusively for one type of PA connection.

Customers should always confirm the amplifier's output configuration before installation. A speaker should be connected according to the amplifier and speaker manufacturer's specifications rather than simply matching the physical connectors.

Broad 85Hz–20kHz Frequency Response

Ahuja specifies a frequency response of 85Hz to 20,000Hz for the PS-400TM.

This range is suitable for the type of speech and background-music applications for which a compact PA wall speaker is intended.

The lower end of the response contributes to the reproduction of lower-frequency content, while the upper end extends into the high-frequency range needed for vocal detail, music, announcements, and general program audio.

It is important to understand that a compact 16W PA wall speaker is not intended to replace a dedicated subwoofer or large full-range entertainment speaker in applications requiring deep bass. Instead, the PS-400TM is optimized for practical distributed audio where clarity and coverage are key priorities.

86dB SPL Rating

The manufacturer specifies 86dB SPL at 1kHz, measured at 1W/1m for the PS-400TM.

SPL, or sound pressure level, provides a useful reference for evaluating the speaker's acoustic output under the specified measurement conditions.

For system designers, this specification can be considered alongside amplifier power, speaker quantity, room size, installation height, acoustic conditions, and the desired listening level.

In a real installation, perceived loudness will depend on many variables. Therefore, the 86dB specification should be used as a technical reference rather than as a guarantee of a particular volume level in every room.

Clear Speech and Background Music

The PS-400TM's design makes it particularly relevant to environments where both speech and music are part of the audio program.

Public address systems often need to reproduce announcements clearly enough for listeners to understand spoken information. At other times, the same system may be used for background music.

The combination of a woofer and dome tweeter provides a practical configuration for these mixed-use requirements. Ahuja specifically describes the PS-400TM as a high-fidelity two-way, 100V multi-purpose PA wall speaker and identifies background music applications in environments such as offices, banks, restaurants, and showrooms.

Compact Wall-Mounted Format

The PS-400TM is designed as a wall speaker rather than a conventional floor-standing or bookshelf speaker. Its compact form factor makes it practical for installations where floor and desk space should remain available for other purposes.

The official specification lists dimensions of approximately 133mm wide, 209mm high, and 130mm deep, with an approximate weight of 1.60kg.

Because the speaker is designed for wall mounting, it can be positioned above normal furniture or equipment, helping keep the audio hardware out of the way.

The relatively compact dimensions also make it easier to integrate into commercial interiors without dominating the visual appearance of the room.

Movable Mounting Bracket

A movable mounting bracket is supplied with the PS-400TM. Ahuja specifies that the speaker can be mounted in either vertical or horizontal positions.

This is a practical feature because every room has a different architectural layout. A vertical orientation may be more appropriate in one location, while a horizontal orientation may make better use of available wall space elsewhere.

The ability to adjust the mounting arrangement can also help installers position the speaker according to the intended listening area.

White Cabinet for Professional Interiors

The Ahuja PS-400TM is available with an elegant plastic cabinet in white, and Ahuja's catalog also identifies a black cabinet option for the model. The white version specified in this product listing can blend naturally into many commercial and institutional interiors.

A white enclosure can be particularly suitable for offices, educational environments, restaurants, retail stores, showrooms, and other spaces where the audio equipment needs to remain visually unobtrusive.

The cabinet's compact appearance allows the speaker to perform its audio role without requiring a large amount of visual or physical space.

Ideal for Offices

Modern offices frequently require audio for announcements, background music, presentations, and general communication. The PS-400TM provides a practical option for distributed audio installations where wall-mounted speakers are preferred.

Multiple speakers can be installed in appropriate zones and connected to a compatible PA amplifier. The selectable power taps can then be configured according to the needs of each area.

For example, a reception area may require a different output level from a corridor, meeting area, or larger open workspace. Proper system design allows the speaker installation to be adapted accordingly.

Suitable for Banks and Commercial Facilities

Ahuja specifically identifies banks among the environments suitable for the PS-400TM.

Commercial environments such as banks often need unobtrusive background audio and clear announcements. A wall-mounted speaker keeps the system organized while providing coverage from an elevated position.

The 100V line architecture also makes the speaker relevant to distributed commercial sound systems where multiple speaker locations may be required.

Useful for Restaurants and Showrooms

Restaurants and showrooms can benefit from a speaker that handles both music and announcements.

In a restaurant, background music can contribute to the overall atmosphere, while announcements may occasionally be necessary. In a showroom, music and promotional announcements can be distributed through the same PA infrastructure.

The PS-400TM's two-way design, flexible power selection, and wall-mounting capability make it a practical fit for these types of installations.

Educational and Institutional Applications

Schools, training centers, offices, and other institutions may need distributed audio for announcements, events, background music, and general communication.

A wall-mounted PA speaker can help place sound closer to the intended listening area rather than relying on one central loudspeaker.

The PS-400TM can therefore be considered for educational and institutional projects where a compact 100V-compatible speaker is required, provided the complete amplifier and wiring system is designed appropriately.

Real-Life Use in Bangladesh

For customers in Bangladesh, the Ahuja PS-400TM can be a practical choice for a wide range of commercial and institutional sound installations.

Consider a retail showroom in Dhaka where background music needs to reach customers throughout the space. Several PS-400TM speakers can be positioned around the showroom and connected to a compatible 100V PA amplifier.

In a restaurant, the speakers can be mounted on walls so that tables and customer areas receive distributed background audio without placing large speakers on the floor.

An office can use wall-mounted speakers for announcements and general audio, while a school or training center can deploy them as part of a centralized public address system.

The key is proper system design. The speaker should be matched with an appropriate amplifier and configured according to the required 100V or 8Ω operating mode.

A Practical Solution for PA Installations

The strongest advantage of the Ahuja PS-400TM is its versatility. It is not limited to a single type of audio installation.

Its 100V power taps support distributed PA applications, while the 8Ω low-impedance option provides another way to integrate the speaker into a compatible audio system. The two-way driver arrangement supports both music and speech, and the supplied movable bracket makes wall installation more flexible.

For professional installers, these characteristics simplify the process of designing a speaker system around different room requirements.

Why 100V PA Systems Matter

A distributed 100V PA system is fundamentally different from connecting ordinary low-impedance home speakers directly to a conventional amplifier.

In a 100V system, the amplifier and transformer-equipped speakers are designed to work together as a distributed audio network. The power tap selected on each speaker determines its intended power draw from the line.

This allows multiple speakers to be distributed throughout a building or commercial space while maintaining an organized system architecture.

The PS-400TM's 16W, 8W, and 4W power taps therefore provide useful flexibility when planning different audio zones.

Designed for Everyday Commercial Audio

The Ahuja PS-400TM is not positioned as a specialized concert speaker or high-powered home-theater system. Its strength lies in practical everyday public address and background music applications.

Its 16W RMS rating, compact dimensions, two-way driver configuration, and selectable power settings make it suitable for environments where the speaker may operate as part of a larger distributed audio system.

This makes the product especially relevant to businesses and institutions looking for a dependable wall-mounted PA speaker rather than a conventional consumer entertainment speaker.

Professional Installation Is Important

Although the PS-400TM is straightforward in concept, professional installation is recommended for commercial 100V PA systems.

The installer should determine the required number of speakers, amplifier capacity, cable routing, power-tap selection, and overall system load. When the 8Ω mode is used, the amplifier's impedance requirements must also be checked carefully.

Correct installation helps ensure that the speaker operates within its intended specifications and that the complete PA system performs reliably.

A Balanced Combination of Features

The Ahuja PS-400TM combines several features that make it particularly versatile for distributed audio:

A 16W RMS power rating provides suitable output for many background-music and PA applications. The 100V line design allows selectable 16W, 8W, and 4W power taps. The 8Ω option provides additional compatibility. The 93mm woofer and 47mm dome tweeter form a two-way configuration, while the 85Hz–20kHz frequency response supports a broad range of speech and music content.

The movable bracket then adds installation flexibility, allowing vertical or horizontal mounting.

Together, these characteristics make the PS-400TM a useful component for properly designed commercial audio systems.
