How much louder is a wall


Recommended Posts

Let's say I have one BTL 18 in a box and another in a wall. Same car (toyota celica t23 or t20) same power. I know it depends on many things but what will be the difference on the meter between the well build box and the well build wall. Does anyone have been on this road before from box to wall?

It will my daily drive and I am going to listen to music all day long. I am willing to sacrifice my back seats for more dB's but I really wanna know does it worth it. Maybe 5 dB's ( I've done my research and was a comment by HHH Ed "five or more dB's " ) ?

Its my car I won't be riding in the back seat... :/ . And I love music more than everything.... lows ftw :give_rose:

I am aiming in the 147-150 range.

So what yo think ? I want to build it as loud as possible, does it worth removing the back seats for more dB's. Plus...a wall looks back ass!!!

The car i am thinking about walling... or maybe a T20

Depends on alot of things, but I would think a wall might be a little louder as you are greatly decreasing the cabin space, so big sub in a smaller area vs. big sub in larger area.

All BS aside, If I see one more comment in here that is NOT about the pre-sale, I will start the vacations. And that includes the trolls feeding the trolls.

try it yourself and let us know? Im going to guess wall, but thats just my guess. Ive seen some vids of an eclipse with 2 TC sounds 18s (not in a wall) that looked like it should be loud. Busted his windshield, lots of windshield flex, lots of eveything flex from what i saw.

woman..cant live with em...cant shoot em...guess were all fucked

You might be a Redneck if you use your leftover gutters for a speaker box port...
