Im looking for a sub that going to be loud when it needs to be but also has SQ. I want peoples input on these 3 subs and if you know of any others in similar price range/RMS range feel free to throw those ideas out there to. I wanna know likes, dislikes advantages of one sub over the other anything along those lines trying to get as much input as possible so i can make a well educated descion.

2 doubles, surface area, power, etc.

Means more output.

I'd look at the Subtilis VVX's too, OP. They look to be pretty badass and the price is awesome.

I'm going to have to get myself one of them before the price goes up. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

Yeah, ditto. I'm lovin' the way they model up.

Thank you and I will look into those subs. I do understand that 2 subs = more surface area and power but what i am asking is what surface area vs rms does for loundness/soundpressure/sq

I have not heard any of them, and i would say u cant go wrong with any of them but personally i doubt the DDs will provide good SQ. However lots of people run dd on here.

Lots also run FI, and though i have never heard them i would say i would go with these over the DDs. I think the ssd's will have decent SQ because they list them as a daily driver sub and not a max spl sub.

I have an AQ amp so perhaps im biased but i like the amp, its better than the other amps i have used, so i believe they will make quality subs. Now i asked them about the SDC2.512 and they said tune it 34-35 and it will be perfectly fine for rock/metal.

they will all get loud no doubt, so i guess if i were to buy one of those i would go FI for SQ, but thats just a guess as ive never heard any of them

Hypothetically:

Doubling power adds 3db, doubling surface area adds 3 db.

3db is the human perception of a noticeable change.
