Thank you for the sentiment, Brendo. I've been very curious about this sub. The reviews of the pre-v4 were mixed leaning towards not satisfied. Unfortunately when most review on this site, they don't make it clear what version they are referring to so I have to find out for myself about v4. I bought them because I trust Andrew has optimized the design given the constraints he had to work within. I've also been so satisfied with all v4 so far that I did not care to look elsewhere. That satisfaction extends to the real wood finish.
