I want to correct myself the HSU has 2-3 dB more bass from 31.5hz to 80 hz (not 40hz)
PB4000: 20hz; 112.3 25hz: 113.3 31.5hz: 114.8 40hz: 116.8 50hz: 118.7 63hz: 117.7 80hz: 116.2
VTF3MK5: 20hz: 106.2 25hz: 111.4 31.5hz: 116.2 40hz 119.9 50hz: 120.3 63hz: 119.1 80hz 118.4
also the "chest" slam bass is mostly MID bass not deep LFE which is what the OP is after (50hz to 100hz)
If he wants more LFE and wants to spend all his $2000 on 1 sub then the Rythmik FV18 will serve him better than a PB4000 as it has significantly more ultra LFE output from 10-20hz
