BTL's do great in small boxes. I've heard one in 2.5 cubes and it was awesome.

for $30 try it out. if it works, sweet, u got a box for $30. if not, then it doesn't. still cheaper than buying wood, building a box and finding out it *****...

I have mine in 3.5cubes each and they do great, i dont think you will have any issues going to 3.0

people on term pro think it'll peak high. what do you guys think. maybe lower to mid 40Hz's? obviously there're tons of factors coming into play with the install but ballpark guesses anybody?

Is it exactly 3 cubes? Before or after sub displacement?

You are an r-tard and obviously have no idea about the relationship between port area, net volume, and tuning.

Go with the box, you'll be fine.

The box will peak higher than say, a 4 cubes box with the same layout, tuning, and port area. But in car, the transfer function helps out on the lower octaves a lot... and all cars peak differently.

Just do it.

Agreed!! Not to mention time too.


3.5 is about the min. But hey Ive heard them in 3 cubes and they where "ok".:D

i originally wanted to do 3.5cubs @ 35hz. we'll see how this plays out. should get the box in about a week when him and i have time to meet.

as long as it sounds halfway decent and isn't excessivly peaky i'll be happy.

theoretically if it's gonna peak higher with the smaller net volume, are the lows gonna suffer?

well i dropped the sub into the box and it sounds okay, but not the best. i can tell it doesnt have enough room for some of the low notes. it peaks around 40-42Hz. The lows could be better and the higher notes are very peaky, too peaky.

I'm gonna try and see if mob's 3hp hybrid will perform better in this box, and then i'll also try out a memphis mojo and see how it hangs. In all honesty i should build a 4cub box for this guy... but i really wanna use this box.....


what subs perform well as daily drivers in 3cubs @33hz?
