Say I made a 4 cubic foot box put a BL15 inside with 1500watts rms, then used the same box popped in a BTL15 in the same box with 3000watts rms. Would the BTL be much louder. I'm a little confused to how much watts make a difference in car audio, everytime someone asks if they should go for 1 powerful sub, or 2 less powered subs, people always vote for the 2 subs due to cone area. Would the btl make you feel and hear noticably more bass then the bl with my given senario?

4 foot after displacement?

yes, but that`s not the point. i`m trying to firgure out if the btl would be noticably louder than a bl when put in the same enclosure as the bl. i know for sure it`s louder or else there would be no point in the btl line, but i guess i`m just trying to get a mental image of how loud. i guess i`m a little confused because everytime someone pops on the forums and says they have say 2000 watts to give a sub and ask if they should get either 2 bl`s/q`s/ssd`s or 1 btl everyone always goes for cone area as the winner.

well from what i have read and been told..... the BTl is the most efficact sub in FI's line...

so the btl would be louder watt for watt

bl 1watt<BTL1watt

With double the power it will definitely louder. Unless you are asking about the BL and BTL with 1500w.
