Avantgarde Extreme 35 (2025)

The Extreme 35 is a magnifying glass for your entire signal chain. It will reveal the noise floor of a bad DAC. It will expose the grain of a cheap transistor amp. It will make a mediocre recording sound like absolute war crime. (I played a 128kbps MP3 out of curiosity. It sounded like wet cardboard being torn in half.)

There is a specific kind of anxiety that creeps in when you sit down in front of a six-figure audio system. It’s not the fear of breaking it—though at $250,000, the Avantgarde Extreme 35 should come with white gloves and a therapist. No, it’s the fear of underwhelm . What if, after all the hype, it just sounds like... a nicer speaker?

Does it have flaws? Yes. It is physically imposing. It is ruthlessly revealing of bad gear. It costs more than a Porsche 911.

Daft Punk’s Random Access Memories . Nina Simone’s Sinnerman . Radiohead’s In Rainbows .

Have you heard the Extreme 35? Are you planning a pilgrimage to Munich to demo them? Drop your hot takes in the comments below. Just don’t tell me your Bluetooth speaker sounds "just as good."

The Extreme 35 uses a fully horn-loaded 15-inch carbon fiber bass driver, coupled with a "Double Bass Array" that fires into the floor. It loads the room itself. The result is the most tactile, physical bass I have ever heard without a separate subwoofer. It will make a mediocre recording sound like

And isn't that the entire point?

The "35" in the name refers to the 35 centimeters of throat depth, but also to the 35 years of horn research Avantgarde is celebrating. The thing is built like a Panzer tank. The wood is hand-polished. The carbon fiber midrange dome is so rigid you could probably use it as a wheel chock for a cement truck.
