I've never really owned a sub before so I guess I'm a little shocked at the amount of bass it puts out. I'll probably get used to it eventually..I have had my 122L sealed tempest for about 5 months now. It still impresses me every time I fire it up. It should be the last sub I own. I'm 35 and my crank it till my ears bleed days are over. Also anything more than this sub and I am sure my neighbors would complain.
