The Reveal - Micro Bookshelf Speaker with Subwoofer

I recently built a new set of Micro bookshelf speakers. My goal was to make something budget friendly and simple for beginners. SO I looked around for parts for a budget speaker. Here is what I came up with. I used the Dayton PC83-4 as minds and the Dayton ND20-4 for tweeters. The crossover is a simplistic 1st order crossover with a BSC circuit and a resistor on the tweeter. All in all the total cost of the build should be around $60 fo the components. I aam personally really happy with the sound. Check out the video for a quick build tutorial and sound test.

Re: The Reveal - Micro Bookshelf Speaker with Subwoofer

When I model this in Vituix, the molded response is flat when the tweeter is wired in reverse polarity. If wired with the same polarity, there is a massive dip in the response at 2300Hz. How did you wire yours? Were you able to get measurements either way?
