Fostex 168S (old style w/wizzer) and 167e

I always prefer a slight bass 'hump' and built it into my design using the Fostex 168S. My cabinet is 24L instead of 21 but I wanted to explore putting either of these drivers in a simple ported box.

Max flat (above picture): 168S goes deeper in smaller cabinet. Port for 167e is 2" x 2".

21 liter cabinet allows either to go deeper than max flat box plot but also allows tuning of bass 'hump' which warms the sound in my room and to my ears. The newer 167e 'looks' like it would sound very nice in a box this size. Ports for either driver are approx. 2" diameter x 1" depth. Easy boxes for great sounding speakers!
