8” car audio tapped pipe

I kinda ‘fudged’ the exit in the sim ?? Any ideas/opinions Before it gets wired up and plays?

My buddy built/rendered this after we looked around in HR for something fun .

‘Guesstimate’?

Looks like a bass reflex to me, does not look like the port slot covers the cone at all.
I'd probably have wrapped the port in an "L" to the back of the cabinet to lower the Fb, cabin gain and voice coil inductance will probably make for a downward slope from 40Hz to 100 Hz as it is.

Big surround on that driver, what's the make and model?

 

[Booger weldz]

Custom made with parts from the ‘lord of bass’ vendor

I think it was this originally

Fb

 

[weltersys]

2.5 ohms at Fb, that's low for a 4 ohm, and high for a 2 ohm, do they call it a 3 ohm driver?
Any frequency response measurements?

 

[Booger weldz]

It’s looks just like the slightly underdamped sim …. A little bit of a ‘fart box’. (He used an ‘spl meter’ and a series of closely group test tones )

You guys take the DIY hobby to the CSI tv show level!! 😜
So after the thiele.small forensics ..what was the outcome?

 

[Guerilla]

Im very curious about the fr in the car without eq. ..Or the eq settings to make it flat.
Cheers!

 

[Booger weldz]

Hope this works

Looks like this (plus some inductance kicking in up top)?

It's rolling off the HF if that's what you mean.....

I bet they give a nice butt massage.

 

[maxolini]

If the subs are flushed inside the driver seat 😜

It's great.Thank you.

Like the equations you share for the upper and lower mass corners 🙏🏻.
