No doubt there is a lot of improvements that needs to be done, such as how you sound test at the end, how to smooth the goldy lining etc.....but this is a very good FIRST attempt to custom your very own portable speaker. There would be tons of not satisfactory including the lighting holes on top, the way the bass sound, most of it has to do with tons of practises. I would still give 5 start out of 5 for the attempt. You see, you would slam the table, wish you do a 2x3 instead of 1x3 battery when you actual use it. You find that, instead of Lithium Ion batteries, you might even tempted to venture into Lithium Iron Phosphate batteries. lol...quite a lot, I know...good attempt. The HVC Creation cut out perhaps was the best thing you ever done so far.
