approx. how much louder

[antonmiller 8]

all right so i currently have 1 12" bl 2008 model and im thinking up my new set up and im throwing some things aorund. i was thinking one 15" btl or 1 12" BTL but then i remembered that 2 12" BL's should be louder than a single BTL and i was just thinking how much louder would 2 12" BL's be compared to 1 12" bl.

It would be 2 12" BL in a custom ported enclosure in the trunk of a little cavalier 2 door. it would be 2.5 cu ft per sub with 39 sq inches of port per sub and a tuning of 32, and on a rockford 2500 (be approximatly 1400-1500 per sub rms)

compared to a

single 12" bl in a 2.5 cu ft after displacment tuned to 34 hz with 39 sq inches of port. also on a rockford 1500

with the single 12 i hit a 145 DB on a sine wave sealed up at the kicks with an ac mic. i wanna hit a 148-150 will the 2 Bl's do it for me?

i just wanna make sure it will be a huge noticable gain.

thanks,

Double the number of subs and double the power "should" gain you the 3-5 dB you are looking for. In theory, it will gain you 6 dB, but it rarely happens. Too many other factors to be a perfect world inside of a car. . .

thanks you for the reply. do you know how much "in theory" a 12" BTL on rockford 2500 would be compared to my 12" bl on a rockford 1500? i really wanna hit my goal with 1 12" but i dont know if its possible, i just love people's faces when i say "nope just one 12" lol

Hey for your first setup was it 1500 or 2500, im just curious as im looking to get aroudn 145 from a 12 in btl. Thats my goal and i have an orion 2500d which is around 2500 rms at 1 ohm. Since you had a bl, im just curious how much you were giving it.
