A multi-sensory experience focused on sound clarity and visual design

Hand-crafted by a former physicist turned sound engineer in pursuit of sonic perfection

Embrace Your Ears

We prioritize auditory well-being with clean, balanced sound and state-of-the-art technology. The partiers of this generation get to experience the most powerful speaker systems ever created. But the effects of long term exposure to these sound cannons has yet to be discovered.

While night club sound today has the potential to sound really good, most of the time it’s frankly unbearably loud and unbalanced. Neptune’s mission is to redefine club sound standards and create a new paradigm for parties: a culture of celebration that honors the body.

We create immersive sound that gives you goosebumps while keeping your ears happy. The sound should be so clean that you can have a conversation in front of the speaker. Your body might be sore, but your ears won’t be!

Welcome to the World of Hand-Crafted Sound

We are a team of passionate audiophiles and experts in our field, led by founder Albrecht Köhler, a former physicist turned sound engineer with a deep understanding of acoustics and a relentless pursuit of audio perfection.

Our hand-crafted speakers are the result of years of research and experience, combined with a meticulous attention to detail and a love for beautiful design. Each speaker is designed and built with a single goal in mind: to deliver the ultimate listening experience.

We work one-on-one with clients to produce one-of-a-kind sound systems. Our speakers are made from top of the line components and materials. Each one is crafted by hand to ensure the highest level of quality and performance. The result is a speaker that not only sounds incredible, but also looks stunning.

Whether it’s a warehouse party, a luxury home, a unique architectural space, an event space, or an outdoor festival, Neptune is dedicated to the crispest, cleanest sound.

Our most portable version of club sound.

Plug and play pole-mounted system actively powered by a 8000W Powersoft amplifier built into the subwoofer. You’ve never heard a 15'“ subwoofer with such a massive low end. It also kicks like a mule. And the top easily outperforms most 18” bass reflex PA speakers while being only half their size.

Specs & Dimensions (WxDxH):

Sub:

15” high-excursion driver, 1600W AES, -3dB@33Hz; 18.75” x 26.5” x 21”, 75 lbs

Top:

10” ultra-low distortion driver, 400W AES, -3dB@70Hz; 1” compression driver (polyester diaphragm) on 90x40deg horn, 80W AES; 11” x 11” x 19.5”, 26 lbs

Total height adjustable between 5.8 - 7.5ft
