[QUOTE="user 1447, post: 676361, member: 1447"] oh no .... im aqctually very clear as to what actually happens - the second post in your link agrees with me as to the effects ie you get 3 db out of doubling the amplifier power and 3 db by adding the other sub because it doubles the surface area which is 6 dbs extra but you wont get another 6 dbs if you add only one more sub with the amp power it requires ie to double the power from two subs you now need 4 amps in total and to double the surface area of two subs you need 4 subs - so each time you want 6dbs extra you need to double the amp power and also the number of drivers - so you dont 3 to 6 dbs just by adding another sub each time thats a basic that anybody who knows about speakers should know ;) .... as i said in Car audio we had to know this because we were aiming for actual specific numbers that were measured by RTA eventually and getting your hands on a trophy depended many times on how well you did your maths and adding up ;) [/QUOTE]
