Question about sealed isobaric enclosures...

[Spoooon]

I was doing some reading about how you can get the same output from a woofer in a big box by doing an isobaric setup. From what I was reading, the whole point was to get the same output as a woofer in a larger box, but from a smaller one. But what would happen if you didn't reduce the size of the box? I have a couple of 8's that I can play with, so I was thinking about setting it up like that to see what happens.

Too much airspace and the cone excedes it's limit and distorts. Also if your box is large and not properly braced it will flex absorbing some of the speaker energy causing a loss of volume.

I thought some isobaric enclosures were safer for the speaker because it didn't allow the speaker to exceed its limits.

They are but he is talking about making a box to large for the speaker.
