Is it common for these speakers to rumble/flutter a little when there's some serious bass going through them?? Is this BAD?? These are my first pair of 'nice' monitors so I'm not sure if this is normal for most speakers this size. I haven't had this issue listening to the same recordings at the same volume with my older KRK speakers. However, the clarity and definition of these monitors is leagues ahead of everything I've used so far.
Kind of a "wooshy" sound? Like a "ssshhhhhhhh" along with a big long 808 kick or bass guitar note? Port turbulence. Too much air moving through the front ports too fast. IMO it's a design defect (edit: maybe defect is too strong a word.. design compromise?) with these monitors, and really the only black mark on an otherwise world-class, stellar product.
After trying out a bunch of others I still went with the Sonodynes, as nothing else at this price point can touch the clarity & accuracy of these monitors over the rest of the frequency spectrum. I work at pretty low volumes (low enough that the port turbulence doesn't come into play), but it's a little disappointing when I crank 'em up for clients or for pleasure listening.
No, there's no damage being done, the sound you hear is friction between the moving air & the enclosure.
You might try slightly muting the ports with something porous to air -- some kind of foam, some folks swear by steel wool (tho i'd be careful with that). I haven't really gone there but will probably try some stuff eventually. Don't plug the ports or create too much resistance to the airflow, I believe you could possibly damage the drivers if you restrict the airflow too much, i.e. the tweeter will start to function as a port and that wouldn't be good.
