DOF - Depth of Field Kit for Legacy Speakers (one pair of parts)
DOF - Depth of Field Kit for Legacy Speakers (one pair of parts)
Current status of DOF kits is in stock two weeks for order fulfillment
The biggest little improvement.
Available for any legacy Blumenstein or Cain & Cain Audio speakers
Included is all of the new, specially developed internal parts that are now outfitted standard inside the model year 2018 on moving forward Blumenstein speaker cabinets* - Coral Acoustic Wave Breakers, (in-house designed and hand-made acoustic damping compounds and The Floating Speaker Driver mounting hardware system as well as newer style vibration damping cabinet feet.
After installation is complete, your sound is going to subtly, but pleasantly come alive into an even more powerful focus than you ever thought possible from your Blumenstein speakers.
This suite of upgrade parts is the culmination of all the careful considerations that I have developed as minor upgrades over years of trial and error in pursuit of tailoring and tuning the acoustic and electric properties of each of these internal parts to produce a clearer, more powerful voice from the same cabinets and drivers.
There are now options for prior Thrasher 8" Full range and Orca Sub/Dungeness series of 6.5" subwoofers as well, outlined below.
*The DOF upgrade kit is compatible with all prior bracing styles dating back to 2006. However, the DOF kit does not (and cannot) include the new Douglas fir internal braces that underpins the model year 2018 and forward designs.
I’ll do my best over the phone to help you get great results on installation day.

Yes, these are indeed all of the main internal parts that now go into the regular production (model year 2018) Blumenstein loudspeakers. (Except for the locally sourced solid Douglas fir internal braces which are now glued in during construction)*
To top it all off, I even throw in a set of the new soft urethane feet to replace the felt feet that originally came on the bottom of your pre-2017 Blumenstein Orca speakers - better controlling the transmission of the Orca speakers' mechanical vibrations into neighboring walls, furniture, audio components.
This makes a Blumenstein speaker that you already own even more of a hot rod - more "rubber meeting the road" in terms of additional in-room bass and full spectrum acoustic energy meeting the air from the improved damping materials.
Coral Acoustic Wave Breakers (and necessary mounting adhesive, not included) and The Floating Speaker Driver mounting hardware system help shape high-frequency resonances produced by the speakers.
--The D.I.Y. kit comes with installation instructions, telephone, and email support and almost all the parts you’ll need for the install. The rest are things that you’ll probably have around the house - namely, a screwdriver, solder iron, silicone adhesive, super glue.
Please note that the Terminal Plates are a separate (additional) upgrade.
If you use a pair of two (2) Blumenstein Subwoofers, then please add two (2) as the quantity to your shopping cart for the subwoofer upgrade service or kit.
with the passive subwoofer upgrade, you can then relocate the original Dayton SA25 subwoofer amp chassis outside the subwoofer which gets connected by its own speaker wires the same way that the new Benthic passive subs are hooked up.
You could then upgrade the sub amp of your prior active Blumenstein subwoofer to one of the new higher power Outboard Subwoofer Amplifiers, or you can also get just the wooden chassis for your dayton sub amplifier.
8" Thrasher upgrades
Now includes larger Coral Acoustic Wave Breakers and additional internal wiring to upgrade the internal wiring of the super tweeter. The sound of upgraded, well broken-in Thrashers with the DOF kit can be surprisingly good.
Cain & Cain speaker upgrades
I apprenticed with Terry and Leslie Cain of Cain & Cain audio between 2003-2018 and am carrying on their work via the depth of field kit for Cain & Cain Abby’s as well as working on new Cain & Cain models… stay tuned!
*Even if you have a pair of very early, rare, or custom Blumenstein speakers, I'll do my best to design a Depth of Field kit for the speakers that you already own. Just send me an email with a photo of your legacy Blumenstein speakers in their natural setting, and I'll send you a custom price quotation and guide you through the upgrade process.
I've got you taken care of.
