Need help/advice with speaker porting.
I am in the process of building an false chimney breast to flush mount my tv etc. My idea was to sink the centre speaker (Q Acoustic 2000i) into the false wall just above the cabinet.
Below is a picture to give you an idea of how it looks, although the box for the speaker now has sides all round except the front.
The problem is that now the speaker is in a box it sounds terrible. What can i do to get round this? I have been doing a bit of reading and it would seem i can either plug the ports as the 2000ci are rear ported, or move them further from the wall, in this case make the box deeper that the speaker is sat in.
So if i just port the back of the box i have built to sit the speaker in would this work. Or would the sound still not be right as in effect the speaker is still ported into a sealed enclosure, all be it a rather large one?
