Ecophon Solo White Acoustic Panel 1200 x 1200 Square is a frameless, free-hanging acoustic ceiling panel designed to reduce echo, reverberation and sound build-up within a room. It provides a clean architectural look while improving acoustic comfort in offices, classrooms, meeting rooms, studios, reception areas, hospitality spaces and modern commercial interiors.
The panel measures 1200mm x 1200mm x 40mm and has a white Akutex™ FT surface with straight painted edges. Its square format makes it ideal for symmetrical ceiling layouts, design-led acoustic features and rooms where a full suspended ceiling is not suitable.
Ecophon Solo Square panels are used to improve room acoustics by absorbing sound energy. They help reduce echo, reverberation and harsh reflected sound, making spaces feel calmer, clearer and more comfortable.
They are especially useful in rooms with hard surfaces such as plasterboard, glass, concrete, timber flooring, exposed ceilings or minimal soft furnishings.
The panel is suspended below the ceiling as a free-hanging acoustic absorber. Sound energy is absorbed by the panel surface, helping reduce reflections from ceilings, walls and other hard surfaces.
Because the panel hangs independently below the soffit or ceiling, it can improve acoustics without needing a full wall-to-wall suspended ceiling. This makes it useful where the ceiling needs to remain exposed, where room volume needs to be maintained, or where a more decorative acoustic treatment is required.
Ecophon Solo Square is used for acoustic treatment, not structural soundproofing.
It is designed to help reduce:
It will not stop noise travelling through walls, ceilings or floors. If you need to block sound transfer between rooms, you will usually need a separate soundproofing system with mass, isolation and airtight sealing.
This panel is suitable for a wide range of internal acoustic treatment applications, including:
Ecophon Solo Square is a premium acoustic ceiling raft with a clean, minimalist design. The square format works well in modern interiors and can be suspended individually, in rows, or grouped into larger ceiling layouts.
The 1200 x 1200mm size provides a strong balance between acoustic coverage and visual impact, making it useful for both small and medium-sized rooms.
Ecophon Solo Square panels are acoustic treatment panels. They improve the sound quality inside a room, but they do not soundproof the room from external noise or stop noise transferring through the building structure.
For best results, consider the room size, ceiling height, hard surface area, furniture, occupancy level and how the room is used. Larger or more reflective rooms may require multiple panels.
Suspension accessories may be sold separately depending on the product listing. Please check whether the required Ecophon Connect fixing kit, wire hangers, absorber anchors or brackets are included before installation.

Ecophon Solo White Acoustic Panel 1200 x 1200 Square can be used in:
Ecophon Solo Square panels are designed to absorb sound within a room. They are most useful in spaces with hard surfaces such as plasterboard, glass, concrete, timber floors, exposed soffits or minimal soft furnishings.
They help reduce reverberation and improve speech comfort, but they do not block sound transfer through the building structure.
Ecophon Solo Square panels are commonly installed using Ecophon Connect suspension accessories, such as:
Always use the fixing method specified for the chosen panel and ceiling substrate.
This product is designed for acoustic absorption inside a room. It is not designed to stop noise passing through walls, ceilings or floors.
The final acoustic result will depend on the number of panels installed, room size, ceiling height, mounting height, hard surface area, furniture, occupancy and overall acoustic design.
For projects requiring reverberation targets, acoustic calculations or compliance-led performance, seek project-specific acoustic advice before ordering.
Store panels flat, clean, dry and protected before installation. Avoid impact damage to corners, edges and faces.
Keep panels in their packaging until required. Handle with clean gloves to avoid marking the white Akutex™ FT surface.
Ecophon Solo White Acoustic Panel 1200 x 1200 Square should be installed using the correct Ecophon Connect suspension accessories for the ceiling type and project specification.
This panel is a free-hanging acoustic absorber. It must be securely suspended from a suitable ceiling or soffit structure and installed according to the relevant Ecophon installation diagram.
Check the ceiling structure before installation. The ceiling or soffit must be suitable for the weight of the panel and the chosen suspension system.
Plan the panel position before drilling. Consider lighting, sprinklers, air conditioning grilles, smoke detectors, ceiling services, ceiling height and the visual alignment of the panel.
Check whether your order includes the required suspension accessories. Some Ecophon Solo panels are supplied as panel-only items, while fixing kits may need to be ordered separately.
Decide where the panel will be suspended.
For acoustic performance, panels are often positioned above desks, meeting tables, seating areas, reception zones or other areas where people speak, work or gather.
For visual appearance, align the panel with room features such as lighting rows, ceiling beams, walls, furniture layouts or other acoustic panels.
Decide the finished hanging height of the panel.
A lower suspension height can make the panel more visually prominent and may improve absorption within the occupied zone. A higher suspension height can create a cleaner ceiling appearance and help keep the room feeling open.
Make sure the panel does not interfere with doors, windows, lighting, ventilation, sprinklers or required head clearance.
Use the relevant Ecophon installation diagram for the Solo Square panel to mark the ceiling fixing points.
Measure carefully and check the fixing positions before drilling. The fixing points must line up correctly with the suspension accessories and absorber anchors.
Use a laser level or accurate measuring method so the panel hangs straight and level.
Drill and install suitable ceiling fixings into the ceiling or soffit structure.
The fixing type must be suitable for the substrate. Common substrates include:
Do not fix into weak plasterboard, loose materials or unsuitable ceiling finishes unless the system has been specifically designed for that substrate.
Install the Ecophon Connect suspension accessories according to the manufacturer’s instructions.
Depending on the selected system, this may include adjustable wire hangers, absorber anchors, absorber brackets or a one-point fixing method.
Make sure all components are securely fitted before lifting the panel into position.
Carefully unpack the acoustic panel and inspect it before installation.
Check for:
Use clean gloves when handling the panel to avoid marking the white surface.
Lift the panel carefully into position and connect it to the suspension system.
Although the 1200 x 1200mm panel is easier to handle than larger formats, it should still be lifted carefully to avoid damaging the corners and painted edges.
Connect the panel to the suspension accessories according to the specified Ecophon installation method.
Use a laser level or spirit level to check the panel is hanging evenly.
Adjust the suspension wires or fixing points until the panel sits flat and level. Check the panel from multiple angles, especially if several panels are being installed in a row or grid.
If installing multiple Ecophon Solo Square panels, check the spacing and alignment across the room.
Make sure:
Before completing the installation, check that all fixings and suspension components are secure.
Confirm that:
Do not leave panels partially fixed or temporarily suspended.
Ecophon Solo Square panels reduce reverberation and echo within the room they are installed in. They do not stop noise passing through walls, ceilings or floors.
For best acoustic results, use enough panel coverage for the room size and combine the panels with other acoustic treatments where required, such as wall panels, soft finishes or additional ceiling absorbers.
