Here is my thoughts on the two subs you are asking about. I first started with a single Alumapro 10" Alchemy MX ....
Not EVEN enough bass. So next i went to the D6 12" in a sealed box and the D5 amps .... That wasn't EVEN enough , so I went to this slot loaded enclosure ...
That got REALLY loud , but just didn't have the sound quality I wanted and was used to getting from a sealed box ...... So I added these amps to see if more power would help ..... Not even ....
So then I went to TWO of these, and found everything I was looking for ....
