Sealed vs Ported Sub

[Deleted member 48726]

The sub is tuned to 30Hz, so when it equalizes so that the sealed sub has the same response as the ported one, it should inject more than 4dBs of power (2.5x) between 20~30Hz. The third harmonic will be at 90Hz, coloring the bass. Just a thought...

Oh! You didn't write anything about EQ in your other post. And even if you wanted to pull the now sealed response upwards akin to the ported you don't automatically get more distortion you just get decreased headroom and SPL and the distortion will set in at lower SPL than before.
