Harman/Kardon Speakers on M and A Satellite Series

Anyone who has spent time with either the M640 or A660 series, can you comment on the speakers? I currently own a budget Satellite, the L655, and the audio is truly dismal, with and without headphones. Audio is very important to me in the next laptop I get, and all the professional reviews seem to indicate that the H/K speakers are excellent, some of the best audio quality ever on notebooks. What about using headphones? How does the Dolby Advanced Audio system sound with headphones? This is a pretty important feature for me, so I am looking for any further impressions. Thanks

 

I have a M645 with the HK speakers. They are the best I have heard on a laptop. You have to enable Dolby. For some reason it isn't enabled on new machines. I don't know about the headphones. I haven't used them enough to really say anything about them.

 

I was looking at the M645 they have at Best Buy, and there doesn't seem to be any software for Dolby, how do you access it and enable it if it is not already enabled?

I have a Toshiba M645-S4055 and it is the second best audio speakers I have heard in a laptop. The best audio speakers I have ever heard in a laptop is this Dell: http://www.bestbuy.com/site/Dell+-+...uId=9999140800050013&childSku=9684515&count=1

But, DO NOT BUY THAT DELL as other than the speakers. That was the absolute worst purchase I have ever made period.
