slim type 10" subs

[Boz]

ask ko lng kung meron na naka try na ganitong subs, pioneer 10" slim type and xplod 10" slim type subs. around 4,500 each canvass ko, planning to purchase and replace one of my 2pcs 8" subs currently installed.
ok b a yung deliverance ng bass nya, malalim ba? limited kasi yung space ng box e, 4-5 inches lnang ang depth.

I have the Pioneer 8" slim sub w/ a 0.30 cu ft sealed enclosure (ideal is 0.15 to 0.50) located under driver's seat. I'm satisfied w/ the bass, although for SQ lang. Siguro mas importante yung tamang enclosure to maximize the sub.
