Sealing ported enclosure to reduce boom

Foam plugs are really easier than socks.

With socks you have to have the right size and roll it up fairly loosely so not all air is blocked in the port. You usually want only partial obstruction of the air flow through the port.

BTW I also recommend tweaking placement away from corners and walls as the preferred soluton, but obstructing (not sealing) the port is an easy option if that is not possible.

"Sealing" the port is a bad idea. The drivers and crossover were designed to work with the port open, at least to some degree. The suggestions to play with positioning away from boundaries and partially blocking the port with foam or even a sock are legit.

The straw thing was more of a port noise reducer...port chug, and not boom. Two different things.

thanks, you are exactly right. can you hear chug? i.m sure it,s there when cheap speaker manufactures like the one in framingham mass use a cardboard tube. ha. the nice looking aerodynamic fluted ports look cool. why is the velodyne ports slotted across the bottom of the cabinet? guess they would claim measurements of response show an advantage. this is why the inventor side of audio is cool to me. so many different ways to try and produce a sound wave accurately. thanks
