Those are the type of compliments which mean the most. She, your wife, had not been responding to an inquiry by you and she was comparing your HT sound to a known quantity we all share, the movie theater. Congrats on being the winner there.
Also LOL, providing the neighbors periodically with the gift of sound from your system is a good thing. How far down the block can you block out normal conversation?
What have you found out about your box so far? Does it have some weaknesses or strengths? Are there any buzzes or flexing affecting the quality of reproduction? Does the unique angle of the speaker baffle create any unusual nodes or nuls in your listening room? What height above the floor is the box? Have you listened to the output of the box from the vent? What does that sound like?
How many braces did you add to the box? What did the interior finally look like?
