Ok i searched around and it seems that the l7's prefer alot of airspace in order to be ported. Im building my friends box, with 2 12"s in them. Its going to be going into a Carola with max demensions of 33x13x16.

Do you think that the box should be ported or sealed?

Would the ported box get loud, But just sound crappy?

He has ~3.98^ft GROSS, That is not enough for 2 12" L7s ported. And I heard L7s DONT like sealed boxes.

With that amount of space,IMO, I would do 1 L7 ported or a couple of beefy 10's. :naughty:

they will not sound all that great in that amount of volume... Actually 1 of the drivers in the correct box with perform much better then 2 "choked" drivers.

I have done many of tests with these drivers and 3.25 cu/ft @ 34Hz per driver is the sweat spot I have found.

Also, if you want anywhere near the correct amount of port volume for a 1 sub ported enclosure the best your going to do is 2.35 cu/ft @ 34Hz.

it would still sound decent in that amount, just not up to its potential. correct?

i have no experience with L7's.

They liked mine pretty good.

Correct. As for 1 driver.

If your planing on 2 you will most likely have less output then with 1, those drivers will be be massivly "choked".

If you dont have the hatchspace for 2, run one in a max space for a box, youll be more then satisfied.

just go with the 2 ported... sure it will be a small box, but nothing extra power wont fix

when i had my 2 L7's they were tuned to 30hz, they sounded ok for what they were... but no where NEAR any sq

I would just question, WHY?

Why would you want to run 2 drivers and have worst results then running 1, regardless of power.

I guess he can do external ports if he really wants to...that might be better...

I would do just one though...tell him to sell the other one and make some money back...

Ok, ill tell him to do that then. Does anyone have any box plans for that box? Cause i thin he wants to start building today or tomaro. Hes going to be using my 2500D for now.

The specs show they are built more for a sealed enclosure...

ok, well my buddy agree'd to run one sub. All i need are the box plans that you said that are perfect for the one sub
