High Performance Subwoofer Systems for Music and Home Theater Enthusiasts
 
 
It has been our goal from the onset to make every effort to minimize VOC emissions, to use products that are specifically designed to reduce  harmful by-products and the unnecessary use of water and energy and ultimately to build products that stay in use and out of the landfill. In keeping with this ideal, we’ve gone to great lengths to design a compact, lightweight, yet efficient system that incorporates biodegradable, recycled and renewable raw materials wherever possible 

The idea of built in obsolescence has always been repugnant to me. Rather than jumping onto some recent alarmist bandwagon, I have always believed in conservation because it just plain makes sense. The bamboo cladding we apply to the exterior of the cylinder is supplied by a global company that builds systems that clean polluted ponds, lakes and other surface sources of fresh water. The process is a biological one, using no harmful chemicals and, in some cases uses a harvestable  crop of bamboo which is used to pull impurities from the polluted water source. The bamboo used on Blackbird, & Raptor originates in these bamboo crops.

One source lists over 5,000 uses for bamboo. Little known uses for bamboo include the first filaments in Edison’s light bulbs and Alexander Graham Bell used bamboo to fashion a needle for his phonograph. 

Bamboo has the tensile strength of mild steel, yet, unlike iron ore, bamboo is an amazingly renewable source, being the fastest growing plant on earth, growing anywhere from 18” to 3 feet per day! This assures a virtually endless supply while meeting the goal of a sustainable product from another environmentally responsible supplier. 
Once again, after an exhaustive search for a viable and green solution, I designed the baffles to be machined from Medium Density Fiberboard made from 100% recycled material and finished by a Powder Coating Process.

Powder coating of MDF is a cutting edge technology. As with everything that’s new, there were unknown hurdles in this specific application. After more than a year of working with the largest and most technologically advanced US companies, we perfected a method of precision machining, prepping and finishing the MDF parts. The end result has exceeded my original requirements that it be aesthetically correct, resistant to UV (sunlight) and virtually impervious to a standard list of household chemicals. On top of all of that was the requirement that all of these goals be met while employing a process yielding low VOC emissions. The final solution resulted in ZERO VOC emissions.

Powder coating is a unique process that results in virtually no residual waste. The MDF is suspended in a sealed oven and negatively charged. It’s then coated with a specially formulated powder that adheres to the negative charge and melts onto the parts. The unused powder is then collected and put right back into the powder bin to be re-used on the next batch of parts. There is no regular maintenance of the oven or spray equipment because there is virtually no residue waste to clean. The result is a completely coated (no raw MDF surfaces), high quality product.
                                                                                  
 
The A14K amplifiers use a tracking switch mode supply that only supplies transient burst power when it’s required.The result is better dynamic tracking of low frequency transients which satisfies the primary goal of accurate reproduction, but the pertinent benefit here is the efficiency increase and huge reduction in weight. Up to 50% better utilization of the electrical energy taken from the grid versus the typical 40% efficiency realized from the toroid transformer alternative. Use less, get more. The package is also smaller, yielding a net reduction in weight of over 70% and 33% in overall size. That means less energy and raw materials used in production as well as less energy to ship while providing better performance than a similarly high powered conventional amplifier.

the amplifier :
In the past, although I have been searching for a viable, high powered amplifier alternative for 10 years, we’ve used conventional Classes of amplifier. Although tried and true conventional amplifiers are reasonably priced and powerful enough to get the job done, they can’t meet our requirements for reductions in the huge losses in energy to heat and their large size and weight, exceeding 100 pounds (50 kg) in most cases. There is also a considerable price paid in energy and raw materials, or carbon footprint, to produce and ship these old-school amplifiers.  

The enclosure :
If you’ve been researching various options for your high quality home theater subwoofer purchase, you probably have noticed how virtually every company and reviewer equates massive weight with better quality. The truth is that conventional methods and materials make it impossible to avoid this phenomenon of outrageously heavy products.

After a lot of research and leg work, I located a US supplier right in my back yard that allows me to specify the diameter,  wall thickness and stiffness of the cylinder that serves as the basic enclosure for the Blackbird and Raptor. They have a long history of sustainable production methods, including the use of recycled fiber from programs that, for example, reclaim damaged and obsolete books. In recent years the company has reduced carbon emissions by 21.9%, reduced energy per ton by 14.6% and reduced water per ton by 18.9%, while delivering a custom product of very high and consistent quality.

Lighter weight means less energy to transport as well. The weight savings in our enclosure design compared to conventional methods is over 70%. 

Discovering a product that’s made in the US that’s also a world leader in responsible manufacturing of biodegradable products from recycled materials certainly wasn’t the easy way to get from point A to point B. But, there’s little doubt it is the most responsible way.

Having been in the cabinet business for decades, I’m aware of and have used most every wet applied finish. Wet application methods include Volatile Organic Compounds (VOC) emissions. Added to the fact that local, state and federal governments are smothering this problem with ever-increasing regulation are the many other related problems associated with wet applied finishes.

Wet applied finishes require regular maintenance of the spray booth and spray equipment as well as removal of the hazardous over spray waste to a landfill.
