I notice there are 2 ports on the rear of my M60s. I didn't receive any foam plugs with my speakers like some other speaker manufacturers use and I was wondering if one is not supposed to plug those to change characteristics.

Is the top port associated with the tweeter and mid while the lower port is associated with the woofers?

My M60s are pretty bright in my room and I was wondering if plugging the top port with foam or whatever would tame that some? Didn't want to plug'em if it is detrimental to the speaker itself so I'm asking here before I try.

Any feedback appreciated.
