Description

The Sundown SLD series can be considered a “re-boot” of the SD-2 line from 2011. The SD-2 was essentially a “shallow SA v1” by design – meaning it shared the cone, surround, and spider with the SA but with a shorter motor with a shorter coil. The SD series went another route starting with the 3rd generation (SD-3) – tilting more towards SQ and sealed enclosures (this remains true for the SD-4 series as well). Due to popular demand we created the SLD series to add a heavily abuse tolerant “shallow” that likes ported boxes back into the line-up!

Much like the current SD-4 series we utilized solid pole-piece so the SLD can also be mounted directly against the rear enclosure wall to reduce net depth requirements. Compared to the old SD-2 we have introduced numerous important upgrades: pole-piece channels for reduced air noise & increased cooling, top-plate “slits” for better cooling and less distortion, and a magnet ID shorting ring. In terms of long-term reliability we have also bolted down the spider, bolted the motor together, bolted on the aluminum pole cap, and added “mini-XL” lead wires thus ensuring many years of flawless service.

The bottom line is if you need a relatively shallow woofer that will take a beating then the SLD is, hands-down, the woofer for you from our line. If you are looking for more SQ then look toward the SD-4 series.

    Great Product

    Posted by Connor Krist on Jul 09, 2022

    I am happy with the shipping speed, as I got it in 3 days, and I got a free sticker. The subwoofer is awesome I have it on half the power it takes, and it still sounds great. Overall great experience with Down4sound.

    Better than I could have hoped for

    Posted by Jeremy Cliett on Jun 24, 2022

    Having a Nissan Frontier space for a good sub was extremely limited. This is my first Sundown and after swapping this out from a Kicker Comp RT I can honestly say there is no comparison. This thing is STRONG, and hits every bass note I throw at it. It's almost broken in properly and I can't wait to see what it does when I throw more power at it. If you need something shallow this is your sub!

    Have two of these hooked up to 1000rms sundown amp, they pound hard. Sound way better than the two p3 rockfords I had in previously.
