    Sundown vs obsidian

    I'm looking at getting to 12inch subs. The choice is between sundown or obsidian will be sending 1500 watts to them. So 750 each. I know that Jacob is working on both of them I was just wondering if the one is better then the other.

    Re: Sundown vs obsidian

    also depends on budget and goals.

    if you have under 400 and looking for new, oa

    if you have more, then go with the sa

    Re: Sundown vs obsidian

    they are very different subs....obsidian's will have better low end extension, won't take lots of power like the sa's can

    both are great subs

    there low end is about the same. the Fs is not too much far apart. and the box will rule out that rule no matter what the Fs is, in most cases

    Re: Sundown vs obsidian

    I wasn't basing it on the Fs...I thought I read it posted a couple times, maybe it was comparing the skar and sa...which a lot of people say are very similar too

    that's probably the comparison your thinking about.

    Re: Sundown vs obsidian

    I've posted this a few times on here but I suppose it doesn't hurt to outline the differences between the drivers again.

    There are a few items that the Obsidian’s share with the SA’s, but a short list of what is different between the two drivers is as follows:

    Surround material
    Surround shape
    Cone thickness
    Basket type
    Top plate OD
    Top plate ID
    Top plate thickness
    Magnet grade
    Magnet OD
    Magnet ID
    Magnet thickness
    Backplate OD
    Backplate ID
    Backplate thickness
    Backplate machining
    Pole ID
    Pole height
    VC cooling method
    VC winding width (winding height)
    VC OD (both D2 and D4 are different from the SA)
    VC former vents
    --I believe that below this line is what you are looking for--
    Enclosure requirements
    Thermal power handling (SA has the advantage)
    On the TL the SA's are between 0.5 dB and 1 dB louder
    F3 in specified enclosure sizes and types (OA's play a smidge lower - in Klippel testing the Fs on the Obsidian's is a little lower and Cms is slightly higher, which is indicative of more LFE with all other factors remaining the same)

    Both drivers do use a Nomex spider, flat sewn-on leads, and a triple joint reinforcement advantage.
