The DSPPA DSP255IIW is the white edition of the DSP255II 30W column speaker, with a slim aluminium body that blends into light-coloured walls. It suits mosque courtyards, hotel walkways and event halls that want clear sound without a bulky speaker on show.
====
For mosque courtyards and hotel walkways with pale walls, the DSPPA DSP255IIW offers a white, slim column that hardly draws the eye. It is the white edition of the DSP255II: 30W, an aluminium alloy body and a built-in 70V/100V transformer. You get audible, intelligible sound in open areas without a boxy cabinet spoiling the facade.
Why a column speaker?
A column stacks its drivers in a tall, narrow body, which generally steers sound horizontally toward listeners rather than up into the ceiling or down into the floor. In reverberant courtyards and arcades that usually means more words reach the congregation or guests instead of bouncing off the walls. The DSP255IIW column holds two 3-inch woofers and a tweeter.

Where the DSP255IIW works well
- Mosque courtyards and outer arcades: the call to prayer and sermon reach worshippers outside.
- Hotels in Makkah and Madinah: outdoor walkways, entrances and pool decks.
- Wedding and event halls: outdoor seating areas and gardens.
- Schools: courtyards and open corridors with light-coloured walls.
- Villas and istirahas: the yard and outdoor majlis, driven by a small amplifier.
White finish and mounting
At just 109mm wide and 102mm deep, the speaker reads almost like an architectural trim when fixed to a white or beige wall. A multi-angle metal bracket lets you tilt it toward the seating area. DSPPA says the aluminium body resists rust and deformation, but no IP rating is published, so mount it under an overhang or canopy where you can.
Connecting to your amplifier
With its built-in transformer, the DSP255IIW runs on a 100V line from a mosque or school constant-voltage amplifier and can share that line with ceiling and wall speakers. Pick the tap according to how far listeners are from the speaker, and keep the total load well below the amplifier rating.
Tips for a mosque courtyard layout
Spread the speakers around the pillars or perimeter walls instead of clustering them on one side, so every row hears a similar level. Aim them at worshippers with a slight downward tilt, and avoid pointing them at neighbouring homes. Mount them comfortably above the heads of standing worshippers, and test during Friday prayer when the courtyard is full, since a crowd changes how sound carries. Start on a low tap and raise it until speech is clear without distracting echo.
DSP255IIW or DSP255IIB?
Sound and specifications are identical: both are 30W, 376 × 109 × 102mm and 3kg. Only the colour changes. The W suffix is white and the B suffix is black. Go white for light walls in mosques and hotels, black for car parks and factories. For an indoor wall position where you want deeper bass, the DSP2603 wall speaker offers 40W and response down to 65Hz.
Frequently Asked Questions
Is the DSP255IIW suitable for a mosque courtyard?
Yes. It is a 30W outdoor column in a slim white body that runs on the mosque's 100V line. Mount it under a canopy where possible, since no IP rating is published.
How many do I need for a medium courtyard?
It depends on area, background noise and mounting height. Start with one per wall or section of the courtyard and fine-tune the taps on site.
Does the DSP255IIW sound different from the DSP255IIB?
No. The specifications are identical; only the colour differs: W is white, B is black.
