Product Description

The SD-3 10" marks the second under-hung subwoofer. Building on the success of the SD-2 8" model Sundown Audio dove back in and designing an improved 10" SD series woofer to create the SD-3. 

Naturally the SD-3 10" shares all of the low distortion characteristings of the SD-2 8" but also goes above and beyond in reducing depth requirements by using an inverted rubber surround. This design saves about 1" of required depth in front of the speaker so you can mount it closer to another surface. With a mounting depth of only 4.48" to begin with -- requiring NO space in the back for venting (due to the solid pole) and a full 1" less of front depth than most other drivers it has a huge degree of mounting flexibility. 

Distortion was also further reduced by including a large, aluminum magnet ID shorting ring as well. This is an improvement over the SD-2 8" topology (and will be including in the upcoming SD-3 8 and 12" models). 

The SD-3 series truly is a world-class sound quality woofer with low mounting depth, small box requirements, and a reasonable price. 

The parameter set has been optimized for very small sealed enclosures ranging from 0.45 to 0.60 cubic feet. This makes the SD-3 10" the best 10" woofer in our line for small sealed enclosures. 

Xmax = 14.5mm one-way by 70% BL
RMS Power = 500-watts

  1. sundown audio is awesome

    Posted by Ambrosio Maldonado on 4th Dec 2017

    This sub kicks azz. Sound was awesome till I blew the sub. Fried the voice coil. Totallaly my fault. Wrote to sundown to return it for repair and they fixed it for free! Highly recommended and will buy more sundown audio subs!

  2. Not sure how this is considered "B-Stock"

    Posted by Czechxican on 18th Sep 2017

    I am still unsure how this subwoofer is considered "B-Stock", but it sounds perfect and looks perfect. I can't find one single blemish on the thing at all. There was some glue that had run a little bit, like 1 cm, but that's it. If that's what Sundown wouldn't accept, then they have some very strict guidelines for QC, which is probably why they are such a good company to deal with. It really doesn't have but a 30 day warranty, but I already installed the sub and it sounds perfect. I'll be ordering a new amp as well to complete the system. Thanks CAB!

  3. Flawless like new

    Recieved very well packed in the OEM shipping box. Inspected woofer and found no flaw whatsoever. Will be buying another as well as an amp from CAB. Recommended my freinds to the site as well. CAB just became my go to audio dealer!

  4. Oh yeah!

    Minor imperfections noticed, which don't affect performance AT ALL. I wouldn't think twice about buying again.

  5. Love it!!!!

    What can I say deep bass, heavy sucker that you can feel it in your chest when it hits. B-Stock awesomeness. In my case there was no face imperfections that I could notice. Mine just came with a gash in the back of the magnet. Though I did not mind at all as I will not invert the sub and its going in box where I will never see that nasty scratch. Sub performance is great and the packaging is superb.

  6. AWESOME !

  7. Top of the line for a great price!

    I have a quad cab sierra and wanted a subwoofer behind the back seat, so very little room. I have a pioneer 1000w amp that blew two other subs so I bought this subwoofer. A friend that built a custom ported box thin enough to fit behind the seat suggested it. Boy was he right. This sub packs a punch and handles every bit of power from the amp easily. Sundown is , in my opinion the brand that not many people know about so I feel like I'm apart of a elite group. Caraudiobargin made this a very easy purchase! Fast shipping and a great price!
