Only way to find out is to swap it out and see if it happens to a different amp

Your cabin gain plays a role in the response graph so you could be tuned to 32 but peak at 42. You need to lower the tuning it you want more low end extensions as the car wants to peak higher

The team evils are just evils with different softies... And they will not be a 12 inch evil until they can get their hands on a 12 inch basket that's not patented

M5 is helping op indirectly but some people have a hard time seeing it. You learn a lot from this site and if you can't take the help then you shouldn't be here.

Low score for 2 12s on 4k. What's your voltage drop to? Could be the car though.

What did you just say

I need to hear this

Since your cost are going up, the recones arent shipped as "nicely" as they use to be to save money?You forgot to read the last sentence.

Tune to 20 and you will get a pretty flat response curve with good low end... problem is to get low 20 tuning you need a long ass port and when you need adequate port area it makes the design somewhat difficult.

Odd to say the least.

Already fried an amp @ 30 sec. Sorry for ur loss bro

It is much more Re and Xl. You are confining your definition to the actual voice coil inductance. You are forgetting about all the other properties that effect the overall impedance. But I am not going to argue with you. *Edit. Quote fail... Not trying to argue. I'm curious where you learn about these properties. Did you just read online or do you go to school for this?

The inductance in a speaker does change when you put it in a box though.... it shouldnt be called "rise" however. The inductance can be affected by any dielectric. No. The impedance changes. This is due to much more than inductance.... The change of inductance changes the overall impedance of the speaker. A speaker is comprised of a resistance (Zr) and inductive load (Zl) in series. The inductive resistance (Zl or jwl) can be altered by either changing the frequency or changing the inductance L. So yes.

Dude holy shit, take the box back and tell them you want your money back or a different box. You didn't get what you paid for. This is like the 10th time ive seen shops fuck people over on boxes. just try to take some measurements on the port dimensions and box dimensions and calculate the approximate tuning and its probably going to be nowhere near what you wanted. And also mention the port area, there looks to be the size of a 6-7 inch aeroport which is around 40 inches of port area. IF you divide that by 7.5 cubes your looking at 5 inches of port per cube... Its basically a leaking sealed box with a tuning in the high 50s i would assume.
