I tried a 1.4 cu ft box with a alpha 10 and it did not have as much low bass punch as the 1-pi , it was ok but the 1-pi sounded better in the low bass region ,How come??? I tried reversing channels and trading out locations with the same result. Would it be better to move up to maybe a 2 cu. feet box to get the same results as the 1-pi ??? Thanks.
