To port or not to port speakers

I am glad for you, my friend (with whom we play games on  this sites ) make something similar, it would be interesting to see the result on the photo)

For a  Surround channel / limited signal - the impact of sealing the port is minimal.

Plugged Port results in a higher bass extension ... finding a good material for the plug is of some import ... ' rigid foam ' ... for example.

do not block the ports.  they will be fine.  

I'm glad you made it

Thank you and good questions. 
Yes and they sound really nice for mini speakers. They are quite heavy actually. I wish 2 of them were the B&W though. I found my listening home with my B&W’s. 
The port is out the rear

You know, I did not know that there was such a setting. I have Denon AVR 1913

Why not test it and report the results to us?

• Do you have a way to play one of them without putting it into the ceiling?
• Is the port out the front?
• What frequency does the AVR set these to?
  • Small, medium, large? (80, 100, 120, 150 Hz?)

Boston micro 120x

These tiny speakers the ports are probably the only reason you can listen to them without subs. 

But before you go through all of this, why not replace with nice ceiling mount speakers??
