PWK Designs & Philosophy
 
  The Man Behind The Curtain: Featured over the years through Team Toxic Bass, Mobile Audio Concepts, Toxic Enclosure Engineering, Advanced Car Creations, and many other organizations around the world, the elaborate designs of Peter W. Kulicki have consistently broken new ground, set trends, and redefined the role of a “speaker box” in both the home and car audio environment. Today, a whole new scope of acoustic engineering and craftsmanship is available directly from the man behind the curtain.  
     
  The Epitome of Custom: PWK Designs small operation scale is an insurmountable advantage on its own. While larger companies rely on limited variety mass-production and bulk sales to keep a product affordable, PWK Designs operates entirely on case-by-case basis, in other words: One unique client - One unique product.

  Just An Upgrade, Please: If you've been in the hobby long enough, you've probably figured out that it consists of two perpetual investment stages: The initial (generally the lengthiest and most costly) stage is the "trial & error stage" during which you purchase one system after another in an attempt to find one that suits you. As a competitive soul, you may even cringe at the notion that, for each purchase that turned out to be a dud, somebody out there might have already found what they were looking for. The second stage is the "upgrade stage" at which point you've found the sound that you were looking for but you've outgrown it and are ready for more. This, invariably, leads right back to trial & error... Now, wouldn't it be great to have an acoustic engineer on-hand to guide you directly to your next big success? Perhaps even build it for you? Well, here we are.  
 
 
The Science Of Sound
 
  Common Practice: Most of the places that you've consulted have no doubt simplified the process to a generic speaker / enclosure match-up (A) leaving the remainder of the equation entirely to chance.  
     
  Loading environment  
     
  Proper Practice: Obviously, before the sound can arrive at the listening point (C), the transfer, resonance, and grouping of the sound waves originating from system (A) is confined and subject to the acoustics of the container (B), whether that's your listening room or your vehicle cabin.  
     
  The Problem: Most speaker CAD programs (on an off-chance that one is actually used) tend to assume that (B) does not exist, that (A) is aligned on-axis with (C), and that there's an open-air gap of precisely one meter in between the two... That's just not very realistic.  
     
  The Solution: In exploring this a bit further, we can establish that, unless you're willing to re-construct the room or alter the vehicle cabin, the geometry of container (B) is pretty much a constant. We can also establish that there's only so far that you can move about the perimeter of your listening area, especially in a vehicle, making (C) a constant as well. Our key variable becomes (A) - a speaker in an enclosure that will effectively couple the cumulative cone mass to it's respective listening environment (B), at the target listening point (C).
