is 40hz to high for an 15" BTL in a 4.5cft box


Recommended Posts

i have a custom box that's 4.5cft after displacements, but the box is tuned to 40hz. wondering if that is too high, fi recommened 30-32hz i thought my installer knew that i guess he forgot to look under the tech section for the correct tuning for the sub. he just went off the specs that's on the sub he said he tuned it that high so it could play all music. im still watin on my btl to get shipped, so i don't know how it will turn out once i get it installed. any suggestions???

do you listen to mainly rock? if you listen to rap i would tune to 35hz so you can still pick up the lows

so if i keep the tuning to 40hz and if i put on a song like for instants young jeezy put on, a song with major lows once that song is played in that box would it pick up the lows right?

Maybe could bottom out a little bit, but i can´t talk about that sub because i don´t use it, i can asure you that, with a 40 hz tuning, my DD 1510´s and 2512´s SLAM around 30 hz, those subs can play strong frequencies below tuning...
