Single 15" 1,200 Watt SDR Series Loaded Vented Subwoofer Enclosure

This thing whams!! First speaker purchase with Skar Audio and I am completely satisfied. Had other 15's in the past and this is the best one I've owned for the price. You can tell it's not some cheap material, seems very high quality. I can't really find any negatives about this package. If tuned right with your amp you have some of the clearest and deepest bass around for a 15. I highly reccomend this speaker/enclosure package if you have a SUV or a van, only because of the size of the box. You will not be disappointed. I've been recommending Skar to anyone looking to buy any aftermarket audio system. Will definately be purchasing more Skar items in the future!


Haven’t even broken in the sub yet!! It’s great , best I’ve had yet. So far it’s amazing. Great for suvs It’s fun trying to get it into a mustang lol couldn’t do it so I put it In the back seat , big box and sub !


I went from to tens to this bad boy definitely will get your stuff groovin

Without ever playing the sub the actual box stinks

I played the sub for maybe 5 minutes with the gain properly adjusted and haven’t used it since. Just letting the box sit in my car over night makes the car smell awful. The sub has not been in use, it’s not a cooked coil. It’s the actual enclosure itself that smells awful so now I’m 200$+ out and can’t do anything about this

Great loaded enclosure

Ported box is large and hasn’t been broken in yet but at this point I am seeing huge flex in my roof, windows and windshield! I have this speaker in the backseat of a Nissan Frontier and it sounds amazing! I’m only running 500rms to it and it is rated for 600rms. I can’t wait to upgrade amps and get the full potential out out of this sub!! I was running a Sundown sa12 in a ported box and this Skar 15 blows it away effortlessly! Will be loading a video soon!
