I will be building a shelf to house this system once I have more components like players, receivers to replace my old panasonic 6 disk player/receiver. Maybe I'll build a computer too. I have two 4x8" sheets of 3" acoustic foam I'll be using to build absorber/accent panels.
Here's what I started two weeks ago.
The towers are sealed, and they sound better then the hybrids do in my car. They also play very well down into the low frequency range, which I was worried about going sealed with them.
Currently, they are being hit with filler and lots of primer coats. I might wet sand them and finish them with a lighter gray color.
