SteinMusic Super Acoustic Discs

The wall behind your speakers is part of your sound, and the Super Acoustic Discs put it to work. Mounted behind and opposite the speakers, they open the room for the music: vocals gain focus and presence, and the soundstage becomes spacious and tangible. They go up in minutes, and you can adjust them by ear.

The music steps away from the speakers.

The Design

SteinMusic describes the Super Acoustic Discs as the accessible level of its new generation of Acoustic Discs, and already very effective. Each disc measures 107 mm across, 12 mm thin, and weighs about 150 g, so it blends into a living space. Removable nano tape holds it flat to the wall and releases when you rotate the disc slowly, so no tools or room modifications are involved. Each listing is one disc: start with one and grow to six.

What You Hear

SteinMusic says the space behind the speakers opens up, and the music detaches from them and stands freely between them. Vocals gain clarity and presence, and instruments become easier to tell apart. With discs on the back wall, the sound fills the whole room, and the overall picture becomes more organized, with less harshness and blur. Even a pair of discs opens the soundstage significantly. How pronounced the change is depends on your room, your system, and your speaker positions.

Tune It by Position

Height shapes the result. SteinMusic says mounting a disc higher opens the soundstage, and mounting it lower adds substance. You find the right spot by listening, and the nano tape makes experimenting easy.

• One disc: Center it on the wall behind the speakers between 120 and 180 cm high. A good starting point is 160 to 170 cm.
• Two discs: Place both on the wall behind the speakers, about 30 cm from each side wall, between 120 and 160 cm high. Start at 130 to 140 cm.
• Three discs: Combine both positions. The outer discs add openness and the middle disc adds focus and presence. Hang the outer discs symmetrically, at the same height and distance from the side walls, set their height first, then fine-tune with the middle disc.
• Back wall, center: Mirror the front center disc, but higher, about 30 to 40 cm below the ceiling. Height matters less here, and furniture can shape the placement.
• Rear wall, sides: Two more discs mirror the two outer discs on the front wall. With six discs, SteinMusic says the room comes much closer to a concert hall.

Installation

Three nano tape strips, each 10 cm long and 3 cm wide, come with the disc. A 2 x 3 cm piece is enough for testing, and for the final position SteinMusic recommends two to three pieces of 5 x 3 cm each. If furniture sits where you want a disc, the disc can lie on it, which sounds good, while standing upright against the wall usually sounds slightly more open. All Acoustic Discs can be painted with spray paint to match your interior, and SteinMusic says this leaves their performance unchanged.

Where It Fits

The Super Acoustic Discs work with the rest of SteinMusic's room acoustics. They're compatible with the original Acoustic Discs, the H2 system (including the H2, H-Pro, and H1), Acoustic Suns, and Acoustic Diamonds, and everything you've already installed stays in place. You can combine Super and Ultra Acoustic Discs, using the same version in symmetrical positions, for example, Ultra discs at front left and right and at rear left and right, with Super discs at the front and rear center. We're happy to help you plan the positions for your room.

Press Recognition

The Super Acoustic Discs are SteinMusic's newest Acoustic Disc generation, and reviews of them are on the way. Positive Feedback's Robert H. Levi reviewed SteinMusic's original two-inch Acoustic Discs in October 2025 and gave them his highest recommendation. Read the Positive Feedback review of the original Acoustic Discs
