the manual said you need

Compact

1.75 ft3 (49.6 L) + port displacement

2.5” x 12.5” port, 20” long

(6.4cm x 31.8cm port, 50.8cm long)

SPL / Deep Bass

2.25 ft3 (63.7 L) + port displacement

3” x 12.5” port, 20.5” long

no that is not enough area. I recomend atleast 12 square inches per cubic foot, up to 15 if you can get it
