So what do you think of Class D amp for subwoofers

I am curious to hear what folks think of Class D amplifiers for driving subwoofers. An interesting aspect of this is the switching frequency is ~1000x higher for the frequencies in question, as opposed to using a Class D amp for full range.

My home theater is Class D (Dolby 7.1) and my next major upgrade is replacing the amps with Class AB amps, although I will keep the low signal processing part of the amp.

In the high end system, I found a four channel, 450W into 8 Ohms Class D amp from Marantz to drive the four subwoofers. The price was right and I am not living in a fantasy land that it is a JC1 sitting there!

I have formed my opinions but I wonder if others share my opinions as well.

Thanks!

Spatialking,
I have a Mcintosh pre in front of a Mc power amp (300x2)driving the front and a Cerwin Vega (2800x1)driving 2-Electro Voice EVX 180's. In my apinion,you do'nt need a reel good amp for bass. The bass is tight hard hitting and the Mc run very cool because it's not driving any bass.By the way,I use a E.V. 2 way active X-over that has a sub out.I bought the class H amp new for around $450.
It costs a lot more to have the Mc serviced and I bet I won't have to have the Mc serviced for a long time because it's not driving the bass. If I blow the C.V. it's no big deal. Just buy a new one. Take care,Bill
