Box for two 15" L5s


Ernesto

Recommended Posts

Making a box for my friend. He want's a decently loud daily driver so he ended up going with two 15" L5s. Im making his box.

Just wanted to see what you guys think of this:

Cubic ft- 4.0 (per sub)

Tunning- 27hz

Square inches of port- 56"

My question, is 56" square inches of port (per sub) good or is that a bit over kill?

I had 87sq inch for two 15" L7s tunned to 35hz.  In total this box will have 112" sq inch of port for two 15" L5s.

What do you guys think?

I think the port area will be ok, I have 120^2  for my 2 15's >:D

I personaly would raise the tunning to around 30 to 32 hz, 27hz is pretty damn low, everything else looks ok to me

27hz is pretty low, what kinda car/truck is it going in?

I was thinking of raising up to 30hz. He likes to play songs like Lil Jon, youngbloodz, 50 cent, all those songs that have low bass. Will I pick up the lows good at 30hz? I don't have much experience with lows. Im at 35hz kinda guy :^

I personally like 32 to 35 alot, you can pick up the lows just as good at 35hz  I play Young Jeezy in my van at 35 hz  its Violent.

tune it to 32 and I will bet money he is more than happy ;)
