TESTIMONIALS

It’s the confidence I get from finally being able to trust my own taste that makes these speakers great. Music is a way composers, engineers, and most importantly listeners communicate and it’s done in such a personal way, the most valuable thing you can do for yourself and your audience is to communicate with conviction. Quasars give me that power.

Richie Beretta

Artist, Producer, Engineer
Didn’t realize what I have been missing! After multiple mixes, Pulsars boosted my confidence, I was cranking them out so much faster. It was making mixing so much fun. I submitted some mixes I re-did with Pulsars, and clients were blown away by the differences. I will forever be a proud owner of these.

Joshua Young

Studio Owner, Engineer
If you’re struggling with translation, this will end that battle. The sound staging is insanely hyper accurate. What you hear on these monitors, you will hear on literally any system.

Ryan Harvey

Engineer, Producer
I can hear exactly what I need to do to improve my sound… Quasars are a major tool that help me accomplish this. They are the best thing I’ve bought for my studio in a decade.

Justin Melland

Film Composer
Quasars have become my most valued and crucial piece of equipment. They give me total confidence in knowing how tracking and mixing sessions will translate outside of the room… They provide clarity, transparency, and inspiration.

James Meslin

Recording Engineer, Mixer, Producer
The mid tweet coaxial on these monitors presents a midrange detail like I’ve never heard before. These speakers are far from fatiguing while presenting a pristine midrange and transient response. I’m truly over the moon.

ALEX E

Music Producer, Mixing Engineer
Over the years, I have worked with a number of very good speakers in many studios but the Ex Machina Pulsar takes monitoring to another level. These are truthful tools that you can definitely rely on.

Patrick Derivaz

Bass Player, Composer, Engineer, Producer
Everything translated well and felt balanced, the low end was amazing, I don’t need a sub anymore ! I find that I can work at low volume and hear every detail and also listen loud without fatiguing… The stereo image and center are really defined, I honestly can’t find anything that I don’t like.

Manon Grandjean

Recording, Mixing, Mastering Engineer
The Pulsars have been truly game changing for me. They are super accurate, revealing, and the transient detail is incredible which has made the mixing process much more efficient and allowed for more confident decision making. I couldn’t be more happy with them.
