Did one better, measured my woofer and it did as I expected. FRee air was 33hz, in rear box was 47hz, added front box raised again to 57hz. I could touch the cone and make resonance shift way up. Whatever I did that made the cone stiffer raised the fr. In car, I didn't see a shift so maybe its a mute point. Guess the volume is large enough that it didn't have any impact. Wonder if several high displacement woofers are used if the effects will show up though.
