Science is everything
First off this subwoofer is a customers which i just received to build a recone for. The basket was on with only two bolts as the previous owner had broke four of the heads off. Upon removing the softparts and boot, I took a closer look. The slugs had been glued on by what I can only conclude as a drunk Chinese assembly worker.
After more investigation I noticed that on the "cooling channels" that are stupid and ineffective as they are, their machining process was very flawed as well. The fact that they allow visible flaws pass inspection this easily it makes me fear what other tolerances are on the drivers. This is the second HDC3 I have reconed this month, the other was not nearly as bad the pole just wasnt centered. When I am at work I will use shims and see how far off this pole is as well.
Just a sad thing to see I would wish if a company can't get stuff done right in china they could pay the extra few bucks to have it done here the right way. I miss the HD3s when they were built with qualtiy and integrity.
This helps me conclude as to why HDC3s are time and time again quieter on drop in's from DDs. The parts can be as close to identical but with errors like that it will make an impact.
