Well, I have my opinion...
Years ago, before all the availability of design tools, DIY speaker design was something between a crap shoot and the black arts. In those days we DIY speaker builders did compare our designs to commercial ones, and it was common to attempt to clone certain well thought of designs. After all, the commercial designers had all the expensive tools, and we did not.
Now that we have the tools and the knowledge to use them properly, things are a little different. I suggest that as a group, DIY speaker designers have progressed beyond simple imitation, and our design goals and constraints are often substantially different than a commercial design.
Many commercial designers it appears are internally hampered by marketing constraints and cost/profit considerations. Design choices such as materials cost, complexity of construction, weight, size, and visual appeal, and voicing may be quite different between the DIY and commercial camps. Manufactures often work on slim profit margins, with significant marketing and advertising costs. Often compromises must be made to bring a product to market on budget.
For example, in many of my designs, the crossover components may cost nearly as much as the expensive drivers they support. To make budget, a commercial designer may have an allowance of just a few dollars for his crossover, and may also have to choose less capable drivers or materials in order to make his design profitable. DIY designs are generally well constructed, braced and heavy. For commercial manufacturers, weight increases shipping costs, as does large enclosures. To meet a cost point, commercial designs may have self imposed limitations that directly affect the quality of the end product.
In my experience, direct comparisons to commercial designs are far less informative than they once were.
