Seal Them Up For Ultra Low Frequencies!

Just added one of these to my theater powered by a Behringer NX4-6000. Sealed up the port to extend the low end and these two 15s cause CHAOS! I cannot put into words how fantastic these sound even in a 10,000 cubic foot theater! I have 3 18" subs and this setup holds its own against them all! If you really want to feel the DEEP subsonics, seal the port and install some battening. You'll love it! I never thought a car audio setup would do anything proper in a theater but these subs take the cake and eat it!

You'll love them, I promise!

I just thought I new bass. I upgraded from audiobahn 12" and all I can say is these sdr 15" suba are stupid crazy. They define what bass should be about. I have several friends looking to skar now. Fine product.


Unreal how good of sound quality these subs are. I have them in my 08 Hyundai suv there fantastic if I was able to put two more in I would. Best starter pack for getting into audio system this is a great deal honestly is. I’ll recommend Skar audio to anyone that asks about car audio. Crisp clean drops box is clean as can be


They hit hard and definitely a good setup for someone not wanting to spend a fortune

Excellent product as well as service!

We just purchased A LOT of equipment to install in our truck and boat and had excellent service and customer care! We will for sure be back to purchase with them again!
