I considered not using the enclosures but wonder what if any air pressure there is on the back side of the speaker at high speed? You could give it a try and keep the enclosures if you decide to put them back.
Yeah, good point. I have the auxiliary lights that fill the vent holes, so I'm guessing not a lot of pressure. But without the lights, I suspect it would be a good bit.
