Help Me with Custom Made 18"

[hawkson]

Hi,
I got these custom made in China, which is where i live right now(Shanghai)

can you help me with a design? I might buy the FP 14000, clone as on avsforum.

Once i have a design I can ask the factory to make it. Looking for home theater, clean and deep.

What's in it for us?

put it in a box
kidding 🙂
thiele small parameters are neccesery to calculate/sim a box.

 

[hawkson]

here they are

 

[NEO Dan]

FS=35-37hz what is your desired -3dB point?

 

[Richard Ellis]

Is that 117.... Litres worth of Vas??? It does not SIM well plugging in 117 Litres..........Could it be 1.17...Cubic Meters?? It seems 117 Litres doesn't sound right.

The fp14000 as in 14,000 watt amp? For your house? Kinda overkill no?

 

[NEO Dan]

Do I smell BIG fat car audio driver 20-30 mm X-max?
Yep it is ~117l Vas.
Hey Hawkson post up a pic of this ~40lb beast will ya?

That's a mighty smooth impedance curve.

Hey!
I don't have a pic, its sitting on the factory floor in Zhejiang, which is close to where i live in Shanghai. When they get here I'll take pictures.

I have 2 of them, I'll use the FP14000 and I'd like it to rock my world. I live in a duplex apartment, and the subs on are the 2nd floor of the top floor, not worried about neighbors.

As for the low point, I'm not sure. I just want to watch transformers and feel Optimus Prime kickin butt🙂

The factory will also build the speakers according to my specificiations, I just need an overall design.

Thanks

Whats in it for you?

Hi,

FYI,

I'm sorry of not being delivering a 😎 T-TQWT suggestion 😀 but only 😱 a TH

If this TH is built single folded and not stuffed with damping material ( loosing a couple of dB's is IMO mandatory for SQ) and very well braced, it would would sound crappy and hollow.

[hawkson]

I have 2 of them..

 

[NEO Dan]

I have 2 of them..

Do you have a car to put them in?
As you can see they are not going low, but in a car they would.

🙄

I'd hate to have you as my neighbor.That seems like a real D*ck move.

 

[hawkson]

i don't have neighbors!

 

[NEO Dan]

Well you still have a problem, your "custom" driver is not really suited for HT use. More like a better than average prosub in that it can get to 30Hz but not as efficient.

Confucius say you did not choose wisely 😀

 

[hawkson]

huh

well, i already purchased them from the factory. They were supposed to hit low hz after another user on the forum designed them, but the factory didn't achieve the specs.
