Crossover and enclosure design for DIY tower speakers

Hi All,

I am looking for your expert opinions for my DIY project of home theaterTower speakers for a little space.
My room size is 12x12 Ft and my selected drivers are Dayton Audio 2X RS150P-4A which will be in series connection to get an 8Ohm, and for tweeter i have chosen ND25FW-4.
I will be using Yamaha RX-V361 5.1 channel AVR for this.
I have come up with crossover at 3Khz as i will not be using a dedicated mid range driver.
