SQ sub that will work best at low to mid volumes?

OK, thanx for all the replies,
I currently have a Diamond Audio D3 10'' Sub on a sealed enclosure, will that be considered a SQ sub, or will a JL audio or Boston would sound much much better?

that is a good sounding woofer as long as you have a lot of power behind it and a good box design. i wouldnt call it a SQ woofer. it isnt like the dynaudio 9", seas lotus woofer, or even the w6v2, but it does sound good.
