"Better" pics:

Nearfield (computer system) subwoofer/cat scratching post.
Driver: JBL W15GTi Mk. II
Amp: Crown XTi2000

Main sub
Driver: Exodus Audio Maelstrom-X
Amp: Crown XTi2000
Cabinet: eD bespoke
(Mains are 12" Dual Concentrics out of a trio of Tannoy System 12 DMT II midfield monitors, in bespoke cabinets)

Second sub:

M-Design Audio Eleganza Bella (Aura NS12-794-8A drive-unit)
Third sub:
