Best ported 12-inch subwoofer enclosures

Start here: Proline X P12D-P Dual 12" Ported V3. It's the one built like a real ported box — 2.75 ft³ net, tuned to 36 Hz, 3/4" MDF — so you get deep, loud bass without guessing at tuning. Check your sub's mounting depth (7.125" max) and cutout (11.15") before ordering.

Who the others suit:

• NVX NE122P — dual slot-port box with 3.25 ft³; the pick if you want maximum airspace for two subs.
• QPower QBOMB12VL — budget dual vented box, fine for a first build.
• QPower single vented — one 12", smallest footprint.
• Loaded boxes (Alpine W12S4, DS18 GEN-X124D, ZR12.2D) — buy if you'd rather not match a sub to a box yourself.

Skip sealed boxes and cylinder tubes if ported output is the goal.
