Ultimate SQL Car Sub?

    I really never hear peoples opinions on a good SQL car sub.

    When i say SQL Im looking for a good blend of SPL and quality, a sub that can do it all and do it with some emphasis

    RE XXX?

    Something by Adire Audio?

    IDMax?

    Digital Designs?

    What about Crossfire? Never hear about them
    I have no idea

    I know there are personal preferences, but Im not asking for the loudest sub here so obviously personal preference comes into play, im pretty much looking for contenders for the spot, i know a lot of them are probably pretty close :dunno:

    Also the budget is pretty much not important, allow 500 as a max for price on sub.

    (maybe theres something im not thinking of as well)

    Another issue many people like me have to deal with is the fact we cant just go and audition stuff, we need as much feedback as we can get to help us make our decisions. Regardless of the fact there is no real 'perfect sub'.

    Also if you are going to say something is better than something else please give reasons.

    i personally think the TC Sounds LMT based drivers can really hold their own in SQL applications

    I was impressed with the Diamond TDX motor structure. Instead of using a standard ferrite magnet, it uses a neodymium magnet in the center of the voice coil (as a pole piece). The cone was also very rigid, made out of a Kevlar/Nomex honeycombed material. It sounded great in our rep's car, but we never could get them to sound good. But we tried to put them in homie cars with gobs of power in ported boxes on rap.. They don't sound good that way. But they have all kinds of potential.

    So the TDXs have potential but theyre a tricky install?

    yeah. we didn't ever install them in an SQ setup, just tried to make them real loud. I think if done right, they would be an incredibly accurate sub.

    Elemental Designs old A series, or the new Av2 when it comes out. Hell even the current Ov2 is every bit as good as the old A series, and a lot less money.

    my concern would be the frequency extension of the woofers, subs like the XXX dont go down to the low 20hz region which is something that I would definately like. (atleast the fs on the RE web site states the XXX doesnt go down that far) Same thing goes for the H2.Or am I misinterperating something?

    But from what I've seen I really like the Eclipse Tis and Brahmas. The Rl-ps also look quite nice especially for the price.

    With the metal nature of the cone on the Eclipse Ti series what kind of change to the sound would be expected?

    I've never heard a metal cone sub that i would consider calling SQ. the sound is tinny, and most of them, while having some degree of accuracy, lose that same accuracy in the resonantion of the cone.

    Looks like its down to the Rl-P and the Brahma :naughty:

    Fs isnt always a good indicator of low end extension. Model the driver and see what it will do in various alignments. Also you dont need massive low end extension in a car, just decent extension will do and cabin gain will do the rest. Too much extension can make the low end seem bloated; unless you are going to EQ out some low end.

    That said a Brahma is a great driver. What size were you looking at?

    I just have to :rofl: at DD being mentioned for SQ. Most of their drivers are closer to giant midbasses than subwoofers.

    I was looking at 12-inch subwoofers


    I only mentioned DD because somebody said otherwise once :dunno: I know nothing about them. :mamoru:

    A Brahma 12 should satisfy you quite well in the low end department.

    Yea DD focuses mostly on SPL. Havent spec'ed their lower end drivers much, but the higher end ones all have a ultra high EBP, sensitivity and high Fs. They are impressive drivers in some regards, but their low end sucks no matter what alignment the driver is in.

    What would be a contender for the Brahma? I ask this due to often found back order issues of Adire Audio.

    The IDMAX 10V3D4 does not get loud enough for me, although it is underpowered by a Zapco 500m. It has awesome sound quality, however I wish it was louder. I am planning to buy a bigger amp sometime.

    Obviously the Resonant Engineering XXX series.

    Same motor, same basket, slightly different cone, same principle. (both share a dense pulp cone w/ fiber reinforcing, but the XXX sports a sexy inverted dustcap :kdubb: )

    How low should I expect the XXX to go in an optimal enclosure and enough power to reach max excursion

    I dont need sub 20hz but id like something to extend well

    Just as low as a Brahma.

    Don't have numbers, and it depends on what size you get. I have a 15" in a 1.7 cu. ft. sealed w/ 700W RMS and it fucking OWNS.

    i was thinking running about 900-1200 watts RMS

    That is a good power range for a XXX in compact enclosures. If you build a larger enclosure you wont need as much power.
