You've obviously not gone through the design thread. This speaker was developed around certain constraints and a lot of work was done to maximize performance within said constraints. This was not only done through building and measuring, but also meticulous simulations using ABEC. The measurements were more of a sanity check as performance was already well predicted beforehand.
Also:
You're in the wrong forum for this kind of nonsense.
Actually I did, and having about 45 years of experience building high end speakers, I actually have some background on this. Where the objective measures as presented are informative, they do not tell the entire story. I offered a couple suggestions based on this experience.
Again, as I clearly stated, this is a fun project direction and I would like to see where it follows.
I too use as many simulation tools as I can afford as it reduces the number of prototypes many times. I too use use as many objective measures of my prototypes as again, it reduces the number of iterations. But in all that, I know for a fact, models only go so far as do objective measures. There is always the final tune by ear as your ears and your room are not the same as mine. Science. I will say, I can hit my cabinet design in a couple of days, so not impressed there. I prefer passive crossovers and that can take me 6 months at least. Not that I object to DSP, just all I have tried, including MiniDSP and Behringer, have been very disappointing. I will be testing Dirac on my living room soon as I have a broad midrange dip that is not practical to resolve in the passive domain.
An advantage if DIY, is we can do things that are labor intensive or to personal bias that are not practical in the mass market. An example is an asymmetric baffle. In a commercial product, that raises the cost. Not for a DIY. We can evaluate the actual drivers and tune ( with DSP if needed) to the actual drivers as manufacturing tolerances vary greatly. We can even afford to re-tune after a period of break-in as drivers change quite a bit and not always predictably. Depending on your woodworking skills, one can make very non-resonant cabinets that would be cost exclusive in volume. I can also suggest some alternative materials that are even better than MDF. With CNC, we can do thigs almost impossible before and would take too long in production. Anyone who is a woodworker knows about the various difficulties in finishing MDF which can me mitigated by DIY, but difficult in production. Things like PVA shrinkage.
