Bass Reflex Ports

[ketch90]

My speakers in my dorm room have bass reflex ports in the back, but I do not have too much room for them on my desk. How much room should I have from the back of the speaker to the nearest wall or surface?

Here’s a link to the manual. Didn’t say much about room behind, but since it’s a small speaker, you should experiment with distance from rear wall to give the best bass boost without becoming muddy & losing detail & imaging.

The general rule of thumb is whatever wide the port is, is how far from the wall it should be. For example if you have a 3" port, it should be 3" from the wall. This is with all ports (speaker or subwoofer)

The only problem I have is how my desk is set up. The sound from the ports reflects back around because of how it's shaped.

I moved the speakers down to the bottom level so the treble was closer to my ear, but the bass is still boomy and i think it's because of the ports.

Have you tried plugging the ports? I think I've already suggested that. Did it work?

Gotta find my old socks. Would a hand towel or washcloth work?

Yes a sock or washcloth will work, (just roll them up and stuff them in) if you have a pair of black socks that works best, since the speakers are black, it's harder to notice.
