For what style music? Hip Hop is abysmal with less than 8db low end boost. However then it's way too boomy for rock etc. Anyone know what frequency the ported woofer box is tuned for?
I think a higher powered 10" sub in a sealed box would be a huge improvement and require less futzing with the EQ.
I listen to pretty much everything and so I think my light correction is a compromise to achieve relative 'flatness' across the spectrum suitable for any kind of music but maybe not the best for any one in particular. I use Sonarworks speaker and headphones correction to 0.9db of flat at home and at least to my ears this 1db boost to the second bass band and the rest left untouched seems to approximate the reference response I get at home with the exception that total bandwidth is compressed in the Tesla. The lows don't go as low and the highs don't go as high but aren't necessarily uneven if that makes sense, just relatively muddy or distorted at the extremes. Hoping the Infinity 4" drivers will help extend the highs and tighten up the mids through midbass a little. In my impression the spectral balance isn't necessarily needing correction as much as extension and better dampening (lower distortion).
