[Box design approval + Question about woofer placement]

the sub won't unload directly into the port in design one. it will allow the woofer to use all the space inside the enclosure.

design 3 the sub is right behind the port. might run into trouble there

[Box design approval + Question about woofer placement]

shoot for about 3.5 cubes net.

[subs up port back design]

that probably does about 1800 watts on a good day.

you don't need separate chambers

download torres calculator and make a box that's about 8 cubic feet NET

14 square inches of port per cubic foot

port will probably be around 20 inches long.

Might be hard hitting a 140 with that equipment.

what amp?

[box dimensions for dd3512s Question]

can you see that? If so, DO IT.

[box dimensions for dd3512s Question]

I just GAVE you all the external and port dimensions. STOP and use it.

[Help with,which song will be louder?]

If 45hz is 2.5db louder, then obviously 45hz will be...... louder.

nice find

[Help with,which song will be louder?]

i think this one actually hits at 45 hz

[Help with,which song will be louder?]

i think this song hits in the fourties.

this sounds close too http://www.youtube.com/watch?feature=player_detailpage&v=sRWtzEZZDKs

[Help with,which song will be louder?]

if she peaks at 45, play 45.

[What do you think? 2 18's design.]

make the port a little smaller. until it fits.

[box dimensions for dd3512s Question]

Pretty much.

[What do you think? 2 18's design.]

torres and sketchup.

[What do you think? 2 18's design.]

move the subs away from the port opening. closer to the front of the box.

also, swap the two vertical 45's in the back for a horizontal one across the bottom.

[how do you find]

.03 should be plenty.

can you spare more room?

[DC LvL5's Inverted on 7k.Doing a 150@37hz With the Trunk Open!!!]

if he's completely sealed off from the cabin minus the port, then he might gain on the meter some by sealing the rear section to spec. but that might prove to be pretty difficult.

[DC LvL5's Inverted on 7k.Doing a 150@37hz With the Trunk Open!!!]

I'd leave it personally.

[Box tuned to ?( quick ?)]

Just do a single port 8" wide and avoid the confusion. if you do two ports, that's gonna take up more airspace in the box.

[Box tuned to ?( quick ?)]

[2 12's and a 18]

If you sell the 12's to get an identical 18, you'll have more cone area anyways.

[What do you think? 2 18's design.]

The tuning is fine. especially for the hdc's. they will still drop bottom, even with a higher tuning.

[2 12's and a 18]

Its still the same concept... its like saying you cant mix 6.5s and 6x9s...

You're comparing front midrange speakers to subwoofers? not really the same concept.

[2 12's and a 18]

uhm.. no. steve isn't using his doors as the sub source. it's the mid bass to help fill in the gaps that the 18's don't cover.
