Hi!

Does anyone have an opinion on class D amplification?

I was looking for a subwoofer amp and found this:

Anyone know if there are any drawbacks there?
What is a reasonable price on these constructions if they include crossovers?

Are they some sort of budget vesions of a digital amplifier like the Danish TacT?
