Yes but I have never heard or read a complaint about in-walls sounding "nasal" or "boxy". Unfortunately my VP150v2, which is also sealed, did sound nasal so that's why I'm hesitant about the mini-160. If it was me and I was faced with your problem, I'd go ahead with the mini because I'd know if I thought it was bad, Axiom would make it right by allowing me to go with another option. It is a pain to have to go through that though.
