I put my Fi Q 10 ina 6th order bandpass designed by 80 that was geared for the lowend. I have to say this sub sounds awesome on the low-end. I had a problem with my amp and didn't get to listen to it very long but with this box it didn't lack anything on the low-end. 25hz-35hz it was very loud and pretty darn accurate in those frequencies. Well in the amount of time I got to listen to it anyway......More to come in a daily ported box and possibly a sealed box if I have enough wood left.
80's box did exactly what I wanted it to do.....play low.......very low............Thanks 80.
