tHAT IS WAY WRONG! That will tune your box to somewhere around 61-62 Hz...no good

I have a single 12L7 in a 1.8 CF (14x14x23) box with 2 - 4"x15.5" aeroports. that tunes to 46-47Hz. I hit a 146.7db on the new sensor. Not too bad IMO, in a 94 Hyundai Excel HB

 

Well he said it was going to ber tuned between 50 and 60 hz and he also said it works really well buty wood is cheap and comps are plentiful so i'll try any thing

but it does seem kinda small to me as well.

 

are you taking your basket and port displacement into consideration cause your dimentions came out to 2.6 cf .
