Metrology is a past time of mine that I picked up in ballistics school from the military days, as well as being a certified soldering tech for avionics. combine that with my dad being a sonar tech that left me a library of hydroacoustic transducer research. you could say I have ideas of my own

I source my own wire and solder per mildot avionic suppliers. I stumbled into working on cabs out of request and necessity. I don't even play guitar but, I can set one up proper. I grew up in bands and was always around guitar and bass players. I actually play drums and have become a studio owner operator/engineer. I've been fortunate to have kept good quality people in my life that have brought me a considerable skillset.
I had a client tell me the other day that he never really thought about cabinets being faster than one another but, this thing frightens me! I find it surprising how few guitar players are interested in pushing their cabinets performance. I guess it's because I come from the bye-gone era of hi-end home sound systems that had exotic speakers combined with 30 years of aerospace manufacturing AND being a metal head - so yeah...I take notes.
