SPEAKERS, SUBWOOFERS, AND AUDIO ACCESSORIES DESIGNED & HAND-BUILT IN WEST SEATTLE, WA


Our family of speaker designs, including the Marlin, Orca, Triton, and Benthic models, incorporate more than a decade of experience in wood joinery design and development for the sole purpose of single driver, full range speaker and subwoofers acoustics. 

Our historical commitment to the pursuit of minimalism - for the sake of maximum performance - is a unique approach that ensures that every speaker is not only artisan quality and genuinely one-of-a-kind, but also industry leading in terms of actual audio performance and the ability to communicate music. 


WATERLINE CABLES FOR ANY CONNECTION

Waterline Cables are made for performance and convenience to the exclusion of neither.  Just like our speakers - A simple, winning formula.

Waterline Cable, introduced in 2015, challenges the current, almost industry-wide paradigm of inconvenient, inflexible, and downright cheap copper with a fresh sounding, hard soldered, ultra-premium alternatives with a velvety smooth and extremely flexible outer jacket for ease of use day-to-day.  

The production process of these cables is simple: our careful hand solder terminations on selected lengths (even very long) of European manufactured studio/professional cable.  

 


 We have safely shipped our audio products to people from all walks of life on every continent (Antarctica included). 


A Message from Clark Blumenstein, company founder, lead designer/builder:

Set up your Blumenstein stereo and dance, listen seriously, or just sit back in socks and sandals and enjoy the calm ambiance. Find yourself happily enjoying it in your own way, with your own music.

There is tons of marketing noise and hype generated from the endless techno-mill of short lived technology products. Our audio designs stand apart, being obvious to use and timelessly simple in design and long term maintenance. Their goal is to give back to you over the long haul - our hope is for the speakers and audio accessories you’ve purchased from us to bring musical enjoyment to your household for 50+ years. Enjoy!
 

Jeff Dorgay, TONEAudio Magazine on the Orca 3" Fullrange:

Listening to these little speakers extremely near field, the soundstage is encapsulating – sorry, headphones just don’t do this.

CSN’s ‘Helplessly Hoping’ is magnificent, with all three vocalists clearly delineated, floating in front of my head – totally trippy. Crowded House’s “Whispers and Moans” is equally lush, with the speakers disappearing in a three-dimensional presentation that is totally stealthy...

...The Orcas and Dungeness from Blumenstein Audio are fantastic, doing so many things incredibly well. If you’re looking for a small speaker system that not only plays way bigger than its size suggests, but one that truly captures the tonal richness locked away in your favorite recordings, you need to give these a listen.
