Location of vent on a center channel speaker (1 Viewer)

[Mark_E_Smith]

After reading and testing a few loudspeakers that are vented, I was wondering if the vent on a vented center channel speaker should always be facing the front esp if the tunning is above 50 Hz. Otherwise you lose the effects of the port. Am I correct? My center channel has a rear firing port and the 1 m response looks like a near field with no port recorded. The speaker is tuned to 66 Hz but the F3 appears to be about 104 Hz.

Any comments?

Center ports are usually in the front so the speaker can be placed close to a wall or hidden in a cabinet. If the port was in the back it would hinder the breathing of it. A port can be anywhere on the enclosure to work.

Take a look at the Audax center channel or the Adire LCC. They both have vents in the back. I doubt the guys who designed those would have put them back there if they didn't work.

Thanks for the posts,
I may just be over analysing and not using my Clio correctly. It sounds real good, and the male voices sound natural.
