    Sorry, I was out of the office most of yesterday (an ULTRA rare occasion). As for shipping the recones, they will settle and glue down just fine as the surround is very flexible by design. Prices on recones have not changed for quite a long time, we unlike most other brands have held our pricing steady, while costs go up. I will find out why those were shipped with no protection or stand.

    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.

    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.

    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?

    No such thing as rise, Im guessing your trying to find ways to build a more efficient enclosure. There is a write on here about impedence, I'll try to find it.

    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.

    I read mention of checking power and ground connections, but didn't see any result. Have you checked them all? Also, where is your volt meter wired to? Is it wired to the rear battery? Or somewhere up front in the vehicle?

    I have not checked power/ ground connection connecting to the amp and was also going to check the rear ground to frame, I will tomorrow because its raining here. The volt meter is wired right to the inputs of the amp.
