I know what you mean about cheaper components and slower voice coil reaction times.
I had some really cheap non branded subs in a box that someone gave me once, and if i wanted to listen to anything that had a fast-ish beat with the bassline coming in on the off-beat, then there was no audible gap between the beat and the bassline, just one blur of wobbly bass, the speaker literally couldnt keep up.
