Is this a fight Oh I seen the vs. and thought it was a fight:crap:

Are you walling the back seat off for the Alpha?

Heads up, same size, Alpha vs BTL is a good race for output, it comes down to enclosure design moreso than anything.

Here, you have to add in that the BTL has more cone area...

LOL, my buddy has the 15 alpha and our friends BF has an 18 BTL and he wants to see who is louder because we went into the audio shop he works at and asked if they had a TL cuz one of their ex-workers said they did and the people didnt know what a TL was lol, and that is our best shop lol.

Yeah times 2 on the cone area. There is a formula for figuring out cone area I have it somewhere and cannot find it right now. But really to many variables:crap:

No the alpha is not walled.

Yes I know the BTL has more cone area, but from what i have read and heard the alpha is louder then the BTL if they are the same size again from what i have been told.

Yes I agree it is alot to do with the install, I will see my friends BF's install possibly tomorrow

Yea I know the cone area equation its all good. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif and yes I know there are many variables I am just wondering to get more of a general idea

Cone Area Equation = Pie(3.14) R(Radius of the circle fool!) ^2(Squared)

One 15 = 176.62 roughly

One 18 = 254.34 roughly

Alpha is a good woofer. Btl also gets loud. In my opinion, Alpha sounds 10x better

I'm saying BTL Louder.

Trunk car with a 15 vs an SUV with an 18.

Yup.

if the BTL 18 only has 4.5 cubes i highly doubt it. simply because the BTL is less efficient and is cramed in way to small a box...

If you can fit it, go with the BTL 18, if not go with the BTL 15.

Funny thing was that the Alpha was louder then the BTL. The kid was pretty upset. lol

How much louder (any numbers?)?
