Since you asked JP. Nope not the amp it had a distorting sound so left it. Always heard these Energy subs were pretty good, so for $10(350.00 new) why not. This thing is well built with a nice hard rubber on the driver and well made speaker connections are a plus. I will probably put it with my Jamo 8 inch in my small living room. The Jamo by itself is rocking my couch I can’t imagine two. Specs say it goes down to 30ish hz. \nCleaned her up and she looks like new.
