Single sub setups

[BassHead99 10+ year member]

I was wondering if you would be able to tell a difference (by ear) between a single sub setup? I was considering either running two 15s or 1 18. Would there be any advantage to one setup over the other? I'm talking more musical wise not just which one is louder, if that makes sense.

single sub setups usually lack cone area and have only 1 motor to work from. So if you don't mind these 2 aspects then you will be fine.

depends on box, sub, power, etc..

Its not a 1 vs 2 thing as mentioned.

To roughly figure your cone area, find the area of a circle the size of your sub. IE:

7.5*7.5*3.14= 176.625 (15" sub)

176.625 * 2 = 353.25sq in of cone area.

9*9*3.14= 254.34sq in of port area (18" sub).

So 2 15"s > 1 18"

This usually aids in being louder. Some people like alot of cone area, with a little power, some like a little cone area with alot of power. Some like alot of cone and alof of power //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

I'm not talking about the output of the subs. I know one will be louder than the other depending on the factors. But if you were to just sit in the car would you really be able to tell if someone had a single sub setup vs. multiple subs?

too many factors to determine that

a single sub will be just as loud on 2000 watts....as two subs on a 1000 watts if using the same make and size of subs

I disagree. Although the amount off watts is the same the second options has double the cone area and therefore translates roughly into a 3 dB gain. +3 db = double the power or double the cone area.

i think you read that wrong

single sub = 2000w

2 subs = 1000w (500 a piece)

will be the same

Yes I did, I was was thinking 1000 watts a piece. he's correct.

No, if your going for SQ then 1 sub will be fine.

Believe me, I've had a few shocked faces when they see that I'm only running 1 sub...I mean it is a BTL with 3kw, lol

yes it does kick *** when people hear your stuff and say holly #$%^ whats in ther 2 12's,10's,15s and you get to say nope one 15 biatch plus one 18 is pretty sweet in my opinion

SQ tryout a Critical Mass UL12 I ran one on a DD M3 in my Saeen for about 6 months...It's output and SQ was awesome...I used a 1.2 cu ft sealed box....
