Get the MOST bass without subwoofer --- ??

Ahh yes...but the big engines still have more potential. How many rotary or small displacement V8 cylinder engines do you see going 300 MPH in 1/4 mile? The F40 2.9 Liter was also turbocharged as I remember. I'd say the comparison between the small displacement engines and SPL is a little off...fun to talk about though! There is nothing that I can think of off the top that you can do with a smaller engine that you can't do with a bigger one...maybe rev higher? I imagine it would all be an efficiency issue.

It sounds to me like it'd be similar to trying to set an SPL record above 250 Hz...

Taln...explain what the downside is to the vented and bandpass enclosures. Give the rest of the story.
