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!

Dont know if this is applicable or not,used on 2 way legacy speakers,sure the bass went deep,but it wasn't natural,and it wasn't any better then what comes out of my counterpoint,the counterpoint shows its bass entirely with whats on the recording,if its light on the recording that's what comes out if its good on the recording that's what comes out,class d seems to really bring out more then really whats on the recording,overemphasizes if anything.
All of this anti-Class D hysteria is ridiculous Except for the fact it sounds terrible.
And when companies like Conrad Johnson,Coda any number of other companies get on board,then ill get off my flat earth,talk about financial gain make and sell some class d amps.
Coffey - how do you know what is on the recording, ,Ah it might be something called listening.
did you hear the news,Nelson Pass is going to start making dig amps.That will happen when Glen beck runs for president and his boyfriend Karl Rove runs for vice pres.
I get wound up i cant help, i will listen to em again,honestly i wonder if the ones i had were broken in,i listened to em for awhile,but it wasnt like i had thousands of hrs on them
