UPDATE: Firewall for Loudspeakers Production, or How DARPA missed the Audiophile Boat

Dear esteemed Customers,

Thank you to all who have responded so far with regards to the Firewall for Loudspeakers launch. Additional responses are still trickling in as more and more people read the news. Here is a link for anyone who may have missed the last Newsletter announcement about our latest, most advanced product, the Firewall for Loudspeakers. We look forward to more responses which will enable us to lower your introductory price yet further!

Years of Effort

The Firewall has gone through a lot of research and development since its inception. What began as a novel idea about implementing Skin-filtering by exploiting the naturally occurring Skin-effect of current running through a wire has been expanded upon many times since its inception. Today we are actually using field structuring around the conductor in unique ways. The Firewall 64X is a LessLoss proprietary technology, based on precisely positioned directional metallic particles within a thermoplastic carrier. The result becomes kind of a micro-transformer. Kind of a ferrite core filter. Kind of a directional set of A/C diodes. Very much kind of a near field Blackbody for signals. That pitch black background, so important to stable "3 AM" type sound quality, is getting set to a higher and higher bar at every step of our way. People keep asking, 'Can it really get any better than this?' Answer: you bet! When the Firewall for Loudspeakers is connected to the signal at the speaker terminal, it brings a cosmic change to the sound quality.

How do we make it?

Well, we don't. We assemble it. The core production of our proprietary technology is carried out by a certified specialty lab by men in what can only be described as hazmat suits. This is actual photography from their state-of-the-art facilities:

The above machine makes the proprietary Firewall components.

How is it done?

It's done by laser.

Direct Metal Laser Sintering (DMLS), also known as Laser Powder Bed Fusion (LPBF), is an Additive Manufacturing (AM) technique designed to use a high power-density laser to melt and fuse metallic powders together. This process has the ability to fully melt the metal material into a solid three-dimensional part, unlike Selective Laser Sintering (SLS).

SLS was originally developed in the mid-80's under sponsorship of DARPA. This process has the disadvantage that resulting parts have porous surfaces. Expensive post-processing methods such as Hot Isostatic Pressing are required to reduce the pores. In other words, the parts must be placed in a high pressure argon atmosphere and raised in temperature, then quickly and uniformly cooled, in order to achieve stability and reliability.

More advanced than DARPA?

We are using an even more advanced system, called Direct Metal Laser Sintering (DMLS). Research on this process began in 1995 as a German research project at the Fraunhofer Institute. This new technology was first commercialized in 2000.

From the Wikipedia entry for Selective Laser Melting: (the link is here.)

"Since the components are built layer by layer, it is possible to design organic geometries, internal features and challenging passages that could not be cast or otherwise machined."

Below are actual objects made by our production partners using this innovative, state-of-the-art DMLS process. What's fascinating about the design freedom enabled by this advanced technology is that you can make objects nested into objects, with surfaces and internal voids which would otherwise be absolutely impossible to make.

LessLoss C-MARC

In fact, you could, if you wanted, make all of the above objects placed, quite literally, inside one another. Meshed with one another. Even turned Inside out. This was not possible before.

Hey, we can use this!

That's where LessLoss comes in. Our solutions are so uncommon, that even the 3D laser production guys had to produce at least 80 prototypes before they got a hang on nuances such as repeatability, precision, scale and visible and non-visible surface demands. They use the most advanced software available such as Solidworks, so going back and forth from accountably accurate changes was only a matter of fortitude.

LessLoss C-MARC

The computer process slices the 3D CAD file data into many ~20 micrometer thick layers. The thin layers are, one by one, selectively smelted by the laser which is located in a tightly controlled atmosphere of argon gas. Believe me, this is no desktop operation. Oxygen levels must be kept lower than 500PPM to prevent explosion. The high-power ytterbium fiber laser beam is literally hundreds of watts strong. The laser energy is intense enough to permit full welding of the particles to form solid metal, without creating a porous internal structure.

What is the product compatibility, and how will it look?

The new Firewall for Loudspeakers will be made of four separate units. Each unit will have a speaker terminal which accepts both banana and spade connectors from your existing loudspeaker cable. The terminal will be housed in a small wooden enclosure, each smaller in size than the existing Firewall 64X for power. From here, a short C-MARC™ loudspeaker cable umbilical, highly flexible, will extend to a termination of either banana or spade (you choose which for your application). This will connect directly to your loudspeaker's terminal. One complete set of this new Firewall for Loudspeakers will consist of four such separate units. One for Left positive, one for Left negative, one for Right positive, and one for Right negative. All will be marked clearly for easy installation.

What's the projected price range?

We are talking, most likely, about a just-over-1000 USD retail price point for all four units of one stereo set. (This means just-over-250 USD per terminal.) With an Early Bird pricing as aggressive as possible, largely depending on response numbers, it is in your hands to lower the initial discounted launch price. The discount window depends entirely on participant numbers. It will be best for everyone here on this mailing list if we get the largest amount of positive responses.

So, here's what I want you to do. Please respond to this email (by email response) with just these answers (please answer all three of them):

--- I am expressly interested in the new Firewall for Loudspeakers Early Bird offer in the next few weeks. YES or NO

--- I am expressly interested in the new Firewall for Loudspeakers product but need about 5 or 6 weeks to prepare, and will. YES or NO

--- I am expressly interested in the new Firewall for Loudspeakers product but need about two or three months to prepare, and will. YES or NO

Once the data is in, we will be able to calculate and lock the retail pricing and the Early Bird offer, and then we can send out a follow-up inquiry and work out the release schedule. As always I will keep you informed at every step of the way.

So, please, do participate at this stage with just the answers! Everyone working together like this can bring everybody's speakers to perform sonic miracles, at super pricing!

Thank you for your time and interest!
