box frequency check .

[riddla 10+ year member]

According to re audio box calculator. I've put in the following for a 15in subwoofer.

36 wide x 18.5 high x 15.5 deep.

A square port width of 3.5in and a square port length of 16

It's giving me a box volume of 3.7cubes and a frequency of 30hz.

Can you double check if this is correct please in comparison to other programs you may be using. Thank you.

Why don't you tell us what sub it is... someone might model it in Winisd for ya' and if you give vehicle dimensions maybe help with a box... RE Box calc is a joke BTW

I used Torres and entered .2 as the driver displacement, double baffled and slot ported on one end of the enclosure (see pic below) for a single 15" sub... This IS one of the most accurate calculators but your sub/power and box should be modeled together in Winisd first... then a calculator used to do it right...

If you list your sub, amp, what load the amp is at and max available space (be sure it can be installed)... the sub/box combo can be optimized for your ACTUAL power and vehicle...

Why would you build a port that big just to stuff it with only 2" of clearance to the rear hatch?

Good question... IDK... this is a pic I pulled of the internet to illustrate the port configuration I used in Torres... why they did that?... IDK

Here is the subwoofer specs

OP... can't read that... is it a Fusion?.. wattage rating (RMS)... what amp, car and dimensions... I'm not even sure that sub is worth modeling...

 

[riddla 10+ year member]

I was hoping for a frequency in the 28hz to 333hz range.

Try the link. it works . no car specific as yet. just trying to get a box done. I have a incriminator IA20.1 AMP.

OK... I'll give it a try but you need to list your amp and is it a dual 4?.. I'm just trying to find the correct vent size...

 

[riddla 10+ year member]

OK. Yes.Its the IA20.1 amplifier. the subs are dual 4.

Yes its a fusion. the good old ones.

Subs?... as in plural?.. be very specific please... if you're putting them on a IA 20.1 at 1 ohm, I'll have to account for the power for sure... I don't think those subs will hang BTW...

I already modeled ONE... LOL!.. now you say two?.. I'll look but I thought you said a 15 in the first post...

 

[shredder1 10+ year member]

28 to 333 hz?.. LOL!... that's setting the bar pretty low... you must mean 28-33 hz... correct?.. that's not a great sub... are you in a location that does not have better options?
