Again, not the case, that dip is merely another room related or phase issue. If you take a look at Ilkka's testing of a large and low tuned sub, you'll see that the FR is not affected in the least by any type of standing wave created inside a large enclosure. You do benefit from decreased harmonic distortion at that frequency, but it doesn't affect FR.


Port resonances will show up as a blip in the FR, but with his first resonance being ~250hz and a 24db/octave 80hz crossover in play, it's a non issue.

I was wondering if a circular baffle inside the sub made from foam, or maybe peg board or MDF would be beneficial in breaking up some resonances.
