A Message from Clark Blumenstein

Set up your Blumenstein stereo and dance, listen seriously, or just sit back in your favorite chair and enjoy the calm ambiance. Find yourself happily enjoying the music.

Through the lens of an audio/music historian, I’ve carefully sought out the core engineering lessons from each major era of audio technology. Specifically, I would consider my audio design approach to be a synthesis of the two “golden eras” in audio history.

1930’s early American high-efficiency high fidelity now meets the miniaturization era of 1970’s Japanese “ultra-fi” audio design inside a Blumenstein loudspeaker or audio cable. In my own style, I have incorporated acoustic instrument building techniques in ways that are specifically tailored for high-efficiency speaker cabinets that need to be responsive enough for the kinds of challenging music made in the 21st century and beyond. I have chosen natural materials for every part that is possible to assure maximum longevity of my speakers’ groundbreaking performance - especially in terms of detail retrieval at low to medium volume levels.

Blumenstein Audio’s ongoing independent research into an extensive variety of simulation environments includes a survey of both digital simulation programs as well as numerous real world acoustic environments.

Every day production details are rounded out with a variety of traditional acoustic instrument building techniques such as solid wood, hand chiseled douglas fir internal braces, traditional (pre-industrial style) wood joinery and wood finish products.

Over the past 11 years, I’ve shipped my gear to music appreciators on every continent (Antarctica included). My audio designs stand apart in solidarity from the mass techno-mill of endless hype. Traditionally wired speaker designs are obvious to use and timelessly simple in aesthetic and long term maintenance.

The goal of my gear is to give back to you over the long haul. With basic care, the speakers and audio accessories you’ve purchased from me are going to bring musical enjoyment to your household for generations. 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.
