Bass Reflex Question?

You don't want a conneisseur, you want someone who has made audio *wine* starting with growing, picking, and stomping the grapes! ;-)


Probably to put it as near as possible to a room boundary. BTW, I know of many counter-examples.



No, bass tends to be non-directional. You can point a vent anywhich way you want to, and the low bass will go everywhere.


You can have as many vents as you want to. The things to worry about vents is that they are the right size to tune the driver and the enclosure to the right frequency, and that they don't have excess turbulence at low frequencies and make chuffing sounds.


The usage "desktop 2.0" speakers is new to me. I think that you mean 2-channel speaker without external subwoofer.

I'm familiar with this type of speaker as "near field monitors".

Right.


Not very much. Of course how non-directional the bass is depends on how deep the bass actually is.

I think of bass as being sound below 100 Hz or so, but with these desktop speakers, their "bass" could be as high as 200 Hz or even higher.

There might be a slight advantage to putting the port as close as possible to the nearest large, flat surface.

Desktop speakers are designed to look cool. That defines their vent placement. My Altec's "vent" is actually fake. They are sealed. (now well sealed, damped and stuffed. )

Best acoustic practice is to point the vent AWAY from the listener so any midrange reflections coming out the ports will not interfere. Same as with standard speakers. If it is too close to the driver, it can cause some phase canceling. Easy on a tiny desktop speaker.
