You need 1 good 12" sub Elemental Designs is making nice stuff right now if you only want to spend $120. I would go with Adire Audio and get a SHIVA. Great SQ with excellent Bass. I'm running 1 12" Lamda Acoustics PB 12 LE and kill my friend with Phoenix Gold amps and 2 10" Audio Bahn's. He spent twice as much as I did on Subs and spent 3x as much on an amp. Plus I'm using a Swap Meet $30 pre fab box.
The Lamda is no longer made but once you realize that half the price of a subwoofer is marketing you realize to go wit hthe lesser known companies that produce in small batches.
If your looking for HUGE SPL! This monster is gonna kill everything! They do not list the brand and I forget what its called, if you PM I will dig up the name & review for you. But this thing had insane reviews 2yrs back!
