What the SP-RM3 adds to a Sharp display

The SP-RM3 is a rear-mounted stereo speaker system built for dedicated Sharp large format displays. Its purpose is to bring the audio closer to the picture in video conferencing rooms and corporate digital signage, without a separate speaker unit taking up space on a wall or table. According to the manufacturer, it is a passive speaker, so it relies on an external amplifier rather than having its own amplification.

Key specifications and what they mean in practice

The maximum long-term input is 20 W, the impedance is 8 Ω, and the sound pressure level is 72 dB. The frequency response runs from 0.08 to 20 kHz. The unit measures 370 x 60 x 60 mm and weighs 1 kg, a compact and lightweight size that makes it easier to handle during fitting. Check these figures against your amplifier output and your room before ordering.

Rear mounting and when the speaker stays visible

The rear-mounted design is intended to be unobtrusive, so the speaker blends into the display rather than competing with it. On 40-inch displays the speaker stays visible from the front because of the back chassis design. On other display sizes it is concealed behind the screen. Confirm your display size before ordering, because that single detail decides whether the speaker is visible from the front of the room.

Where it fits in Qatar

Three situations where this model makes sense:

An office in West Bay running hybrid meetings with colleagues in other countries, where clear voices from the display matter more than sheer loudness.
A hotel or retail lobby in The Pearl or Msheireb showing corporate signage, where the speakers should stay out of the way of guests and shoppers.
A training centre in Education City presenting lectures and slides on one large display to a seminar room.

Planning the installation

Confirm the exact display model with the SmartRooms Qatar team before placing the order, since the design is for dedicated Sharp large format displays. Plan the amplifier and cabling with your AV integrator, and make sure the amplifier output stays within the 20 W maximum. The data does not specify an operating temperature range for the SP-RM3, so if the display sits near a window, outside a classroom or in a corridor exposed to Qatar's summer heat, ask us to confirm the installation environment before fixing. Free site surveys are available before any wall mounting.

Request a quote from SmartRooms Qatar with your display model, room size and number of units. Quotations are usually issued within one working day, and purchase orders (LPOs) are accepted for government, school and corporate buyers across all 8 municipalities of Qatar.

Questions about SP-RM3

What is the Sharp SP-RM3 used for?

The SP-RM3 is a rear-mounted stereo speaker system for dedicated Sharp large format displays, designed for video conferencing and corporate digital signage. It suits meeting rooms where remote participants need clear audio, and lobbies where signage plays with sound. Because it is a passive speaker, it needs an external amplifier. Request a quote to confirm it matches your display.

Which displays is the SP-RM3 compatible with?

The product is built for dedicated Sharp large format displays. Before ordering, confirm your exact display model and size with the SmartRooms Qatar team so the rear mounting matches your screen. A free site survey can be arranged for an office in West Bay or Lusail before mounting points are fixed, and quotations are usually issued within one working day.

What is the maximum power input of the SP-RM3?

The maximum long-term input is 20 W and the impedance is 8 Ω. Choose an amplifier that matches these values, and have your AV integrator check the setup before installation. Keeping the amplifier output within the 20 W maximum protects the speaker from damage during long sessions, such as an all-day digital signage loop in a shopping mall.

What frequency response and sound pressure level does it deliver?

The SP-RM3 covers a frequency range of 0.08 to 20 kHz and has a sound pressure level of 72 dB. These figures describe the speaker's capability, not the loudness you will hear in every room. For a boardroom in Doha, test audio with the actual display and amplifier, and review the results with the SmartRooms Qatar team during the quotation stage.

Will the speakers be visible on the display?

It depends on the display size. On 40-inch displays the speakers stay visible from the front because of the back chassis design. On other display sizes they are concealed behind the screen. For a boardroom in Lusail where the screen is the focal point of the room, confirm the display size before ordering so the layout meets your expectations.

Is the SP-RM3 easy to install?

The manufacturer describes the design as allowing fast and easy assembly. Each unit measures 370 x 60 x 60 mm and weighs 1 kg, which makes it manageable to handle on site. Installation should still be coordinated with the team fitting the display. SmartRooms Qatar offers professional installation for the speaker and display together across Doha and beyond.

What warranty comes with the SP-RM3?

According to the manufacturer's data, the SP-RM3 carries a 3-year warranty that matches the warranty on the display. Products supplied by SmartRooms Qatar are covered by the manufacturer's warranty. A school or government buyer comparing several tender offers can use this cover period alongside the warranty on the displays the speakers will be paired with.

Would the SP-RM3 suit a private school in Al Wakrah?

Yes, a private school in Al Wakrah fitting out a new assembly hall or meeting room could pair the SP-RM3 with a large display for assemblies and announcements. The data does not give an operating temperature range for this speaker, so confirm the installation environment with SmartRooms Qatar before fixing, especially if the display is close to a window or a sunlit corridor.

How does the SP-RM3 support video conferencing?

The speaker is optimised for video collaboration, which helps remote participants hear the room clearly. Position the display so sound reaches all seats evenly, particularly in meeting rooms in Al Sadd or Msheireb. When requesting a quote, include the room size and seat count so the speaker and display layout can be planned properly.

Can the SP-RM3 be used for digital signage in a mall?

Yes, corporate digital signage is one of its stated applications. In a lobby or retail unit in The Pearl, a display can show promotional or wayfinding content with audio. Because the speakers are concealed behind most display sizes, the front of the screen stays clean. Request a quote to check that your display model matches before the mounting plan is finalised.

Does the SP-RM3 include an amplifier?

No. The manufacturer describes the SP-RM3 as a passive speaker, so it depends on an external amplifier. Select the amplifier after confirming the display model and mounting position, and check that its output matches the 8 Ω impedance and 20 W maximum input. Request a quote for the display and speaker together to have the whole setup reviewed.
