Yes, it's loaded with 21DS115s. I don't think it does 25hz the way I have it setup with all ports open.
But it's for music only right now so I don't miss it, but I have so much headroom that I can plug ports and go under 20Hz when I get my HT going.
Just loving the extra headroom. I have an extra Skram box in my garage planned for nearfield.
But... although the wife is patient with all this, another BigA$$ NF sub is pushing it LOL
