Get my HD3C15 today

15 square inches? Thats entirely too small. Thats about equivalent to one 4" aeroport, WAY too little for a 15".
Having the sub off to the side is fine actually, I'm guessing you did that to move the sub farther away from the end of the port (inside the box)? If so, I do the same thing.
god dammit tommy. i did it again lol. i meant 15-16" per cube.

as far as the port, yes thats why i did it.

 
Center the sub?.....i always thought it was best to have it over the port...hence CRX style boxes?
Is this only with sub back port back?
he means to center it on the front baffle instead of being tucked away into the port wall corner. i dont know all ins and outs of how air reacts inside, but maybe as the air is compressed in that corner it effects the sub some how.

 
Your are worse than the Chinese dude who does our box labels
lol. hey DJ, i commend you guys for the way you package your subs. the foam inserts on top and the whole foam support the the rest of the sub and double boxing it, at least in my opinion, is a GREAT idea. no offense to FI (as i have owned 3 of their woofers in 2 different models so far and i have loved each one), but your method of packaging is ridiculously more effective in protecting the products.

So far UPS has only managed to break one of them

 
Ohhhhhhhhhhh, ok. haha
4 cubes would put him right at 60 square inches, which is what I recommended earlier. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
i think thats gonna be my next box then //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif. see what kind of difference i get.

DJ beat you to it. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

As far as the sub location, I've done the same thing on multiple boxes with absolutely no issues.

Thats my sister's setup. 10" type-r and a kicker kx400.2 and it throws down very well and has a surprisingly flat frequency response.

You are quite a bit further from the port wall with a much smaller sub and motor structure. Tuck it in too close and the cone doesn't load even

Haha, its just dirty. //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

That port is actually very long, probably farther away than his 15" box.

But to have more of a comparison, I have done similar things with 12" and 15" boxes with similar results.

Honestly, he probably won't see a difference either way.

If it works for you go for it.

 
Honestly when i first saw his box i was going to say something about sub placement.... but i did not want to for some odd reason. And now that i think about it i had some funny noise with my mj-18 when the hole was cut off center..... meh what do i know?
DJL what box size and tuning do u recommend for the 12?
i had positioned the sub close to the port at the recommendation of ngsm. he said by placing the sub closer to the corner, it makes sure that the air is compressed into the port, instead of having it compressed into the corner of the port as well as the port if the sub is farther way. hope that makes sense. but the way DJ explains it, that makes sense too. only way to see what works best for me is to try it i guess.

im guessing, that maybe i got the logic right, but my application was bad.

1.7-2.5. 38-40Hz

 
oh FUCK! ok well i found my info on my box. so here it is. keep in mind this box was designed for a BTL, which has no pole vent.

my box is 15.25" deep internally. my port is 4.5 x 20. and the mounting depth on the AQ is 8.875". so doing the math, i have come to realize that my motor and pole vent on the HDC3 15 is 1.125" away from the port wall. could this be my issue, especially when adding this to the fact that im PACKED in the corner?
