it MIGHT have been a vent backwave distortion

Posted by thump on January 5, 2017 at 17:53:45:
i haven't taken them or the mains outside yet to test for distortion and volumes, but today, i tilted it down instead of propping it up on its magnet about an inch off the floor and even at low volumes, the bass was quite loud as i had the input pegged, but didn't hear any buzzing.

when i turned the input down to about 50%, there was still just a little bit too much bass on some tracks and apparently a lot of cancellation on others, but i didn't hear the buzzing.

MAYBE, just maybe what i was hearing was the sound of the magnet's vent bouncing off the floor or possibly choked a little by the narrow tunnels i created with the jigsaw puzzle edged foam pads i propped it up with. higher frequencies are less prone to cancellation than lows, and there's probably a venturi effect going on through the port too. at lower volumes, i thought i might be hearing a buzz coming out of the port.

before i go all over town looking for a duffle bag large enough that i'll be able to carry it on the bus with, i'll do some troubleshooting to see if there's a reasonable explanation for the anomaly.
