Your media room is loud because the walls are lazy

Most home theatres in Australian houses are living rooms with the lights down. Treat the bounce first. Spend on speakers after the room stops slapping.
People buy a soundbar, then a sub, then a second soundbar. The dialogue still leaves the room and comes back a moment later. That is plaster, glass and floorboards. It is not the firmware.
What you actually need. A real studio stacks absorption, diffusion and isolation. You do not need that to watch a film on a Thursday. You need less slap on the first reflection points and less boom in a boxy room.
First reflections in a typical apartment: the wall beside the sofa, the wall behind the listeners, sometimes the ceiling. Glass opposite the TV is a mirror for sound. A slat panel with an absorbent core on the first hard wall does more than a thicker soundbar.
Open-plan living that shares a kitchen hard floor will boom when conversation starts. The fix is usually soft goods plus a treated wall, not another black box under the television.
Slat face versus absorbent core. Timber acoustic wall panels are popular because they look like joinery. That is allowed. Just do not confuse the look with the job. The slat is the face. The felt or fibre behind it is the work. If a panel is slats glued to a hard backer with no cavity and no fibre, you bought decoration. Decoration is fine. Call it that.
Hexagonal and decorative acoustic tiles help when you cannot commit a whole TV wall to vertical timber: a renter, a narrow wall, a room that already has joinery. Scatter is better than a postage stamp behind the television and nothing else. See acoustic wall panels for slat, hex and decorative finishes.
What slat panels will not do. They will not stop the neighbour's bass. That is isolation and mass. Different product. They will not fix a concrete box on their own. You will still want a rug, curtains with lining, and something on the ceiling if the room is a cube. They will not replace speaker placement. A panel is not a toe-in. They will not turn a living room into a treated cinema. If that is the brief, you need a different specification than a feature wall.
Apartment rules. Glue-up systems can be a bond issue. Mechanical fixings need landlord sign-off. Lightweight panels that hang like art are the political choice even if they absorb a little less.
Measure before you buy. Height of the wall, width either side of the TV, depth available so the panel does not hit the soundbar. Use the panel calculator that adds waste.
If you also want pattern on another wall, the wallpaper calculator keeps roll counts honest, and a room visualizer helps check scale before the carton ships.
A cheap sequence that works. In most Sydney brick veneers: a rug under the sofa; lined curtains on the glass; absorptive slat or hex on the wall that slaps first, usually beside or behind the seating, not only behind the screen; then spend on the centre speaker.
Do not paper the slap wall with vinyl and expect hush. Paper the opposite wall if you want pattern. Let the loud wall do acoustics.
Tehila Maison stocks slat, hex and decorative acoustic wall panels from Sydney and ships nationally.
