Two responce curves: Natural vs EQed (1 Viewer)

[Anthony_Gomez]

I am going to try and use real world examples so that you can model this with your own software.

Suppose a tempest in 260L tunned to 16hz an also a BPD1503 in 160L tunned to 16 hz as well

...after playing around with a few parametric filters you can make the BPD responce look just like the tempest responce from 20hz on up to withing +/- 0.5db (+/-.5db is NOT going to be heard when you consider room interactions).

Since these two systems now have the same responce curve, will they now sound the same within their limits of linear excursion?

(assume that inductance is also accounted for in the EQ)

Frequency response has little to do with the actual sound quality. I think of it as just a helpful comparison tool.
Some terms related to sound quality of bass are: Lumpy, Muddy, Boomy, tight, transient, clean, dull, sloppy, muffled, etc.
A tone at 50hz can sound muddy and be 100db loud just as a different sub can sound boomy at 50hz @ 100db. Yet according to the response, both subs can hit 50hz @ 100db...
Believe it or not, bass is filled with a lot of detail. This is why I don't put specs as priority when choosing a loudspeaker. However, the specs CAN help me sleep better at night.
