I've got Niles HD-LRS speakers (in-wall) as my surround-side and surround-rears. I'm debating putting in a wall-unit that would house normal, exterior speakers or just purchase a low entertainment credenza and stick with the in-wall speakers (for my fronts and center). MY QUESTION... is there a significant reduction in quality with the in-walls vs the normal free-standing speakers? IF I stick w/the in-walls, does anyone have any other suggestions for the fronts and center speakers besides the Niles or should I stick w/the same brand. Thanks in advance for your feedback.
