Yes very nice indeed!! You should put in some bass mechanic and crank that thing up see what she does!! The foam that you put inside the box is this required and what does this do? I am doing my own subwoofers also using 2 12" IDQ v.2 subs and 2 240 watt amps from parts express building my own enclosures, most likely sealed. Using these subs since they are sitting here not doing anything anyways! I'm kinda wishing they werent here, because if they werent I would probably get the same package you got! I bet that thing must HHHAMMMMERRRR
