I switched from JL Audio Fathom F112’s to NSMT Sub Duos They retail for $4,495 each. They are very easy to integrate and give me the best bass I’ve ever had. The next model down is called the Bass Foundation which are $2,500 each. I have not heard them but I hear they perform the same as their big brothers in a smaller room. The If you are interested I’d contact Mike from Audio Archon. I highly recommend the sub woofers and Mike. Just my experience for what it’s worth
