Subwoofers- Best SQ are? HELP!!!!

[Lafiro]

Right now I dont know what I have between the two, probably competition so that would be SPL subs.

oh SQ = Sounds quality ; SPL = Sound Pressure Level.

I was looking into some subs that dont handle to much power but they can do like 10hz to like 1000hz in sound. Most subs only do 25-100.

My question is, whcih company or companies in you opinions make the best SQ sub's?

I was told that for loudness but also quality its JL.

I was also told for just deep hitting loudness its Kicker.

I want the highest quality Sub's I can get. I already have the other speakers changed out running to a new head unit and a 1200watt 4chan amp. So now I need the best subs I can to match the nice sound system it already is.

Please help! I don't know anything else about other companies and need to know what to get based on your experiences/knowledge.

Thanks!!!!!
