Quite a lot of car audio subs are not really suited to home audio due to low ohm loads and the drivers them selfs have high FS numbers.
If you want to have low bass in your home and can do DIY then go for a
www.adireaudio.com and get a shiva or tempest these are great subs for the home.
If DIY is not your cup of tea then for a nice mid level sub a the adire rava is good.
If you want ultimate bass in the home check out
http://www.svsubwoofers.com/ these subs take low bass and take it to another level of quality and SPL.
