I think it looks great. I can completely understand that glue up mistake anyone who works with wood has had that happen to them at some point. The last time it happened to me I was fortunate enough to have used hide glue, so it was just a matter of hot water and a little persuasion with a rubber mallet, and the fact that I use hide glue maybe 25% of the time I should say "very fortunate". I am a true believer in the properties of hide glue, and now that you can buy quality glue that doesn't need a double boiler, I'm really sold on it. but old habits are hard to break. For me It's the slower curing time and I get too impatient and turn to modern PVA. I should add that I love the design of that speaker cabinet it would look great in anyone's home, especially mine :)
