Why do smaller enclosures offer a higher sensitivity at higher frequencies and higher maximum SPL (at the higher frequencies) vs a perfect (assuming no phase cancellation) Infinite Baffle alignment? The only difference I see between the two is that the smaller enclosure will provide a higher acoustic low pass filter (why you're able to dump more power into them, without an electronic xo), higher non-linear distortion caused by waves dissipating inside the enclosure at a different rate than the waves outside the enclosure (improper pressure between sides), and maybe less thermal power handling since the heat from the voice coil would have less air to dissipate into it. In all of these scenarios the Infinite Baffle alignment is more desirable.
Why then, do small sealed enclosures (vs IB installations) have higher maximum SPL or efficiency in the higher frequencies? Are the enclosures releasing stored energy from the rear wave through the cone caused by the complex wave interactions inside the enclosure or what...im stumped.
