I know these aren't Polks, but...
This was something I did for fun more than anything and to use what I had on hand. I basically needed a set of garage/outdoor speakers that I could put anywhere. I had a set of old component car speakers laying around with some curly maple, and this is what they turned into.
Now, they obviously have NO bass, but the imaging and volume I get from an old HK Receiver I had laying around is pretty impressive. Now I just need to figure out a good cheap sub to fill in, and put on a Cap to keep < 2-300 Hz from going to these ;)
Feel free to give me a hard time as this was done with little to no planning
