Efficient woofers

[hdave 10+ year member]

What are some very efficient woofers.

looking to maximize SPL from as little wattage as possible, SQ isnt much of a concern, but still want just a little bit of SQ.

brahma

idmax

etc..

btw, are DD 9512s efficient? how much power would be needed to get loud in a 2.8 NET box @ 35Hz?

Thank you.

selenuim subs are very efficent so are powerbass

are DD 9500 series efficient?

i was TOLD they are, but they seem like they have very stiff suspension and need a crapload of power and SQ isnt bad but not good, but will get loud enough to break ur penis into peices.

is that true?

or are the efficient?

hows the sq on them?

2.8 cube @ 34Hz... how much power is needed to get em loud?

so i use that formula on t/s parameters of woofers to determine their efficieny?

i had a 9515 had around 1800 watts on it doin a 143.5 on the new termlab when we added 2 pa 3000s we jumped to 149

how do u expect it to perform at 1000 watts?

i was thinking of 2 kicker CVR 15s, or 2 CVR 12s ported

maybe a pair of type r's 12s if i can find them for a good price.

or 1 good sub

 

[patalpine]

how many 12s

 

[patalpine]

personally i think you could do better with one ported 9512

power is an issue, i want to keep the amount of power to a minimal, no more than 1000RMS

dont wanna kill my alt too quick

RLP 12's or 15's

avalanche 15's or 18's

they are super efficent (for real speakers) will WANG on 800 watts, and love ported boxes.
