porting a sealed box


Recommended Posts

Based on your other post I would start from scratch and get two matching subs and build a ported box to specs if it will fit. If not stick with sealed or just one sub ported .

subwoofers - two eclipse 88120s

box - 3.4 cubes tuned to 32 hz

amps - aq1200 and pheonix gold zx450

New build :

2 obsidian audio 15s

same amp

6.1 cubic foot box tuned to 32 hz in a civic hatch

What no one seems to be asking here is if you even have the right speakers for ported enclosures. You know, some speakers work better in ported, and some just work better in sealed. Back in the day when I was doing a lot of building, we had to figure all this out based on the T/S parameters for the speakers provided by the speaker manufacturer. Books like the Loudspeaker Design Cookbook were and still are a great resource if you really want to learn this industry. Now a days all the manufacturers tell us what works best with their individual drivers. Don't just cut up a box because you think you need or want a port. Get the spec's for your speaker. If the air space in your current box supports all the proper displacements, then you can cut a port into it and tune it to the right frequency. Best of Luck to you.
