Thanks for your help,
The Bassmaxx ZR18 would more than fit your needs and your budget, while saving you space. According to David Lee, the T-H SPL parameters show a max SPL of 154dB. In a LLT enclosure, you'll easily get down below 16Hz. You may have to get the paper cone version to get up to 80Hz, as the fiberglass coned version starts to roll off above 45Hz.
Cost of the sub and a decent amp will be under your budget limit.
Estimated cost of ZR18: $1000
Cost of used QSC PL 6.0: $1700
Cost of materials, wood, glue, screws, binding posts: <$200
But you really don't need the QSC, as it should only take about 7 watts to reach 120dB @ 16Hz with this woofer in an appropriate enclosure. What the arrangement buys you is lots of headroom and distortion figures more commonly attributed to amplifier specs than woofer specs.
I tested a single ZR18 against an array of 6 EV-18Bs and 4 Altec 3184s, and below 25Hz, there was no contest-- the single Bassmaxx was generating an earthquake while the other drivers were just distorting.
