  • Our take on the Sundown Audio X-Series v.3 8 Inch Subwoofer 800W

    The Sundown Audio X-Series v.3 is an 8-inch car subwoofer built for high output in small enclosures. It uses a stiff cone and long-throw motor with 19mm of Xmax, so it moves a lot of air for its size. Low sensitivity (about 82 dB) means it wants real amplifier power, roughly 800W RMS. It suits bassheads who want big output from a tight space and will give it a proper ported box; it is not a drop-in upgrade for a factory system.

    Best forBassheads wanting big output from a small 8-inch driverCustom ported or sealed builds in tight spacesOwners with a strong amplifier on tapSQ-leaning setups that still want heavy low end
    Pros
    • 19mm Xmax gives long excursion for an 8-inch
    • Works in small boxes: about 0.75-1.0 cu ft ported, 0.3-0.4 cu ft sealed
    • Recommended 32 Hz tuning and 12-16 sq in port area suit deep bass
    • Stiff, heavy motor design (BL around 26-31) handles power
    • Shallow 6.8-inch mounting depth fits tight spots
    Cons
    • Low sensitivity (about 82 dB) needs a powerful amp
    • Wants a well-built custom enclosure, not a prefab box
    • 8-inch cone limits sheer displacement versus larger drivers
    • Not a simple swap into a factory location

    • BuildPraisedBuyers describe the motor and cone as sturdy and well made.
    • Power needsCriticisedIts low sensitivity means it needs a strong amplifier to come alive.

    Questions and answers

    What size enclosure does it need?
    About 0.75-1.0 cu ft ported, or 0.3-0.4 cu ft sealed. Sundown recommends tuning around 32 Hz with 12-16 sq in of port area.
    How much power does it need?
    It is rated around 800W, and its low sensitivity means you should plan on a capable amplifier to get full output.
    Will it fit a shallow mounting space?
    It needs a 7.36-inch cutout and about 6.8 inches of mounting depth, with an 8.70-inch outside diameter.
    Is it good for deep bass?
    Yes. The 19mm Xmax and 32 Hz tuning recommendation suit low, loud bass in a ported box.
    Does it work in a sealed box?
    It can, in roughly 0.3-0.4 cu ft, but it gives up some low-end output compared with a ported build.
    Where is the Sundown Audio X-Series v.3 8 Inch Subwoofer 800W cheapest?
    At Amazon, for $389.99, as of our latest check.
