    This is the basic design, I can adjust it for any size tweeter and have it printed out or possible milled out in a cnc depending on cost.



    Any recommended change or something I should consider ?

    Re: Tweeter Spheres - pics and examples

    Depends on the tweeter. If it has a lip, you want a matching lip. Each tweeter mounts differently. Looks good. It would be nice to see a bit more surface area around the tweeter. I have some paper mâché eggs that I will experiment with also.



    have you been helped by me? i'd love to know. shoot me a PM.

    in general terms, is aiming toward the head rest on each side better imaging than aiming across the dash?

    Re: Tweeter Spheres - pics and examples

    aiming at the rear C-pillar (opposite side) for each tends to work out well - result is a wider sound stage than aiming at head rests.

    you'll need to attenuate the nearest tweeter if they are more on-axis.

    Ok I've done some google and searching, but what is the difference btw on-axis and off-axis? And what do you mean attenuate?

    Re: Tweeter Spheres - pics and examples

    imagine a laser beam coming out of the center of a tweeter (or speaker). that is the axis. you are on the axis (tweeter pointed at you) it is on-axis. if you are not (tweeter pointed away from you) you are said to be off-axis. being off-axis should be further clarified with an angle (in degrees) with 90 degrees being perpendicular. this factors into the polar response of the speaker/tweeter at each frequency. polar plots are useful in determining what you will hear as you move from being in front of a speaker/tweeter to what you hear when it is pointed away from you.

    attenuate is just a fancy word for "turn it down". decrease level/volume of the nearest tweeter and the sound stage will become more centered (since we localize sounds above 3kHz based on intensity (volume) and not on pathlength).

    thanks for asking for clarification. i'm sure it will help other as well.

    The :intent is for each person to have the left tweeter in the left year and the right tweeter in the right ear.

    Here's some well overdue pics of the spheres KHA made for. Fortunately, I had the same tweeters as him, so measurements were easy! I just had to give him angles.

    I used Rustoleum textured spray paint, and it matched my panels very well.

    Re: Tweeter Spheres - pics and examples

    @keep_hope_alive ; is the goal to have the paths cross at a certain point in the vehicle? Part of the reason I ask is that 2 of the vehicles I am thinking of doing this on are pickups, so no c pillar to aim at. I know I can just guesstimate, and am probably over thinking it.

    I'm thinking that what makes these things so interesting is that you can adjust them at practically any given time without modification ...
    This would make perfect sence when tuning for Sound Quality. Wether it be one seat judging or 2 seat judging ... east adjustments ...

    I would suggest to start out by aiming them to your interior cab light ... and adjust from there
