Atlantis Lab AT22C Coaxial Wall Surround Speaker (each)

The Atlantis Lab AT22C is a passive coaxial wall surround speaker that combines mid-range and woofer in one coaxial driver, radiates the highs via the diaphragm cone and is built for wall mounting in a home cinema.

Its cabinet tapers like a wedge: 22 centimeters deep on the thick side, just 15 centimeters on the thin side. That is not a design gimmick; it means the speaker protrudes less from the wall than its data would suggest.

Why the AT22C?

Because surround channels in a home cinema are often the neglected children of the system. The AT22C takes them seriously: 96 dB efficiency at 4 ohms, 37 to 20,000 Hz, 250 watts power handling (peak 500 watts). The coaxial principle puts the sources on one axis, and the manufacturer cites wide dispersion – useful when an effect should not only arrive at a single seat.

What you get

A wall surround speaker in a cabinet of black faux leather with oak that, according to the manufacturer, is suited to wall mounting. It weighs 19 kilograms – so it belongs on the wall with sense and the right anchors, not with optimism. The manufacturer states 100 hours of break-in.

Who is the AT22C for – and who is it not for?

Plain talk: the AT22C is no lightweight and no mini satellite for the bedroom wall. If you are building a demanding home cinema and want a speaker with plenty of reserve and wide dispersion on the rear or side walls, you are in the right place. If you only want a slim, light bracket speaker, better look at lighter wall speakers. Whether your wall can carry the weight is something you check before ordering – we help you with that.

Frequently asked questions

What does coaxial mean for the AT22C?
Mid-range and woofer sit in a shared coaxial driver, and the highs are radiated via the diaphragm cone. The sound sources therefore lie on one axis. The manufacturer cites wide dispersion, which can cover several seats better in surround channels.

Is the AT22C active or passive?
Passive. It has no built-in amplifier and needs an amplifier or AV receiver. At 4 ohms and 96 dB efficiency, the electronics should work stably at low impedances. Power handling according to the manufacturer: 250 watts, peak 500 watts.

How is the AT22C mounted?
The manufacturer specifies wall mounting and describes a wedge profile with 22 to 15 centimeters of depth. At 19 kilograms it needs a load-bearing wall and suitable fixing material. Have the mounting checked beforehand; with plasterboard, caution is required.

Is the AT22C sold singly or as a pair?
The price applies per unit. For a 5.1 or 7.1 system you accordingly buy two or more units. How many you need depends on room and seating position, and we are happy to work it out with you.

Why buy the AT22C at HD Zürisee?
Because wall mounting, cable routing and home cinema configuration are rarely answered online. Our experienced specialist team in Wädenswil advises you on placement and combination, and on request our own technician supports you with delivery and installation on site.
