I am impressed by the response and the sheer power of this subwoofer. I have a Directed 750D running into this at 2 Ohms, and though it says it can only handle 4 ohms, it does remarkably well. I wouldn't spend the MSRP for it, but all in all, for the $50 I spent on it, I would have to say it was a good investment.
