if it is ported you only got about 3 to 3.25 gross after sub and port displacement there is not enough space for 1 ( properly anyway )

 

Image Dynamics IDQ15. An SQ sub... so it's not a bottom dweller. Fast and clean, but I wanted more ooooomph.... so I copied Kwame.

 

ill post the pic in a little bit i have some things i have to do and yes it is ported.

 

i also use 12" single sub set up as well

if you do 1 each 12" ported in about 2.75 net at 30-35 hertz

on a
fi btl
digital design 9512
RE MT
Rd Alpha or heavy weight

and throw 2500 to 5000 watts on it

sub up and port back

it will KILL the lows i can assure you

 

if it is ported each sub is seeing about 1 to 1.5 net

18" sub needs at least 3.5 to 4 net minimum to sound right

 

i could only find the side pic of the car with the 2 18's sorry? ill try to find the better pic later.

ive had multiple dual 12" set ups in a 240, they are great and all for an all around sub rock rap w/e. but im really looking to hit the lows incredibly.
350zspl, how much do you have invested in your single 15" setup?

 

 

I'll leave it up to the spl master, 350zspl, to guide you better than I, but my dual IDMAX12's go pretty deep... and I'm only putting 600w a piece to them.

 

no offense

you are right i should articulate myself better

i am shot is guess

sorry

 

neat idea

but they can't sound good , or lets say they can't sound as good as if they were in optimum space

 

tuning plays a major part to what your after

might be hard to believe but 8" tuned at 30 hertz plays lows very impessively

tuning any sub 30-to 35 hertz really accentuates the lows

now tuning this low , and your gonna lose midbass 55- 65 hertz

are you trying to make me ill , try to account for money wasted


RD Alpha $ 500
BJ Fisher Custom box triple baffle $ 200 - $ 250

must i continue

 

your in florida

feel free to drive to delray beach and you can pick up the box with the 15"

bring $

 

This car, done by 813 motorsports, actually has 5 18" RE XXX, cool idea but not my cup of tea. Where the hell would I put my luggage?

I thought you had people to carry your luggage for you.

 

Your out of your mind.

hertz? dont explain ill research it myself. But basicly it may be more cost effective and less of a headache maker, if i went with two 12's rather than
15's and tuned them properly they would quad the lows like im wanting? also lets say i want to hit the lows for a lil while then i want to change it up to some rock or something and need tighter bass, is this "hertz" thing changeable on the fly?

ha thats alot of flow you got spent on that, but im sure it slams.
originaly from delray here

 

hertz is cycles per second

30 hertz is 30 cycles per second

50 hertz is 50 cycles per second

you get the picture


if your enclosure is aero ports instead on slot ports the you can have different length ports

longer lowers tuning and increase low end
shorter raises tuning and it gets more mid bass

you can have an enclosure with 2 sets of ports
1 set at 30 hertz to slam the lows
1 set at 45 hertz to do well on rock and roll

1 sub , 1 box , 2 sets of interchangle aero ports hope this helps

 

issue if your gonna do 2 each 12" than it will need to be sealed and not ported as i do not think that there is enough space to port 2 each 12" subs

which means you are not able to change tuning on your box if sealed

possibly might be able to do 2 each 12" ported but you will need to find 12" subs that are shallower on mounting depth and require like 1 ft net each


it is cheaper and more cost effective to do i each 15" ported

i am confident that 1 each 15" ported in 2.75 to 3 net with 2500 watts will kill the lows and allow you to interchange ports and adjust tuning to different frequencies
