Bass Cube - Simple Full Range Bookshelf Speakers

Full range bookshelf speakers in a simple design that does not require any crossover. This uses the Mark Audio Pluvia 7.2HD full range driver along with 2x Dayton ND140-PR passive radiators. With some EQ adjustments I've been able to get mine fairly flat down to ~45Hz (at the cost of some efficiency). I'm currently driving these with a Fosi V3 stereo class-D amp and a Topping DX1 DAC and it's my nicest sounding desk setup so far. 

I printed mine using the Supertack build plate since parts this large can have warp or adheision issues even with PLA. I recommend printing this with a freshly cleaned bed and if you're not using Supertack, definitely use some adhesive.
