Depth of Field Enhancement Kit for legacy Blumenstein speakers (2006-2015)

Depth of Field Enhancement Kit for legacy Blumenstein speakers (2006-2015)

from 59.00

The Biggest Little Improvement.  

Available for any Legacy Blumenstein speakers (2006-2015)

The only upgrade kit we've ever offered.

Included is almost all of the new, specially developed internal parts that are now outfitted standard inside the Model Year 2016 Blumenstein speaker cabinets* - Coral Acoustic Wave Breakers, (in-house designed and hand-made acoustic damping compounds - and the specific number of them is given to you per speaker model ordered), Hammerhead Binding Posts, and The Floating Speaker Driver mounting hardware system.

After installation is complete, your sound is going to subtly, but pleasantly come 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 carefully considered small parts that we have developed over years of trial and error in pursuit of tailoring and tuning the acoustic and electric behavior of our speakers to a fine degree of accuracy and balance.   

With the release of the Depth of Field Enhancement Kit, it is now possible for our existing clientelle to upgrading the sound of almost any pair of their Blumenstein speakers that we manufactured between 2006 and 2015.   There are now options for our prior Thrasher 8" Full range and Orca Sub/Dungeness series of 6.5" subwoofers as well, outlined below.  

* Does not include the new Douglas Fir internal Braces that are now standard hardware inside model year 2016 Blumenstein Marlins, Orcas, Tritons, and Benthic Bass Unit cabinets.

Yes, these are indeed all of the main internal parts that now go in to our regular production (model year 2016) Blumenstein loudspeakers.  (except for our Locally Sourced Solid Douglas Fir internal braces)* 

To top it all off, we even throw in a set of our new soft urethane feet to replace the felt feet that originally came on the bottom of your 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 "sleeper" by maximizing their world renown capability to not parasitically bleed sound through thin apartment walls - even though they've now got more going on under the hood with the Hammerhead Binding Posts...and more "rubber meeting the road" in terms of additional in-room bass and full spectrum acoustic energy meeting the air.

 Coral Acoustic Wave Breakers (and necessary mounting adhesive) and The Floating Speaker Driver mounting hardware system help shape high frequency resonances produced by the speakers and also, importantly, our Hammerhead Binding Posts (also included), allow full sonic and mechanical compatibility of our prior speaker models to our new Waterline Cable offerings.  

--The D.I.Y. Kit comes with installation instructions and Blumenstein Name Plates and the necessary adhesive to apply them over top of your existing rubber stamps.

--The "Send Them Back In for Upgrades" Service means that you are responsible for boxing up and returning your speakers to us safely to our mailing address: Blumenstein Audio 4701 SW Admiral Way #105 Seattle, WA, 98116, USA.  We will then apply the upgraded treatments to your speakers.  This full service treatment also includes free return shipping and a free replacement service of the originally rubber stamped (2006-2015) "BLUMENSTEIN" text via sanding down and reapplication by use of our new wood burning "BLUMENSTEIN" iron directly to the face of your freshened up speakers.   

--By custom order, this upgrade kit is adaptable to larger or smaller loudspeakers.  Please email us with the specific modification project you had in mind and we will spec out a price quote.

-12 pcs. Coral Acoustic Wave Breakers

-8 pcs Floating Driver Mounting Hardware

-2 pcs nameplate upgrades.

New options in the drop down menu -

- 6.5" passive or active legacy Blumenstein Subwoofer upgrades for Orca Sub, Dungeness model variants.

We now sell a legacy Blumenstein subwoofer upgrade package.  We list this item as a Kit or Service per each single (1) subwoofer unit because many of our clients opted to purchase only a single Blumenstein subwoofer for use with their pair of Blumenstein Full Range Speakers, and in that case, you will only need a single set of upgrade parts for your single subwoofer.  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 in order to Enhance your pair of subwoofers.   

The legacy Blumenstein subwoofer upgrade kit includes a set of binding posts so that you've turned it into a passive sub.  If needed, the silicone is there to touch up any needed seal to the internal birch ply amp box that we've already built inside our legacy active subwoofer models (active subwoofers are now discontinued.  We only make passive subwoofers).

You can then locate the little original Dayton SA25 subwoofer amp chassis outside the Dungeness max, connected by its own speaker wires.  (feel free to add any length needed).  

You can also then upgrade the sub amp of your dungeness to one of our Outboard Subwoofer Amplifiers, which includes a premium wooden chassis.  If you opt for the Hypex unit initially, then the potential upgrade to the Benthic Bass Unit down the road will reap additional rewards in terms of value for the dollar of a step by step upgrade process.

- 8" Thrasher upgrades

Now includes larger Coral Acoustic Wave Breakers and additional internal wiring to upgrade the internal wiring of the supertweeter.  The sound of upgraded, well broken-in Thrashers can be surprisingly good.  

Even if you have a pair of very early, rare, or out-right custom Blumenstein speakers, we'll do our best to design a Depth of Field kit the speakers that you already own.  Just send us an email with a photo of your legacy Blumenstein speakers in their natural setting, and we'll send you a custom price quotation and guide you through the upgrade process.

We've got you taken care of.
