I recently purchased an acer concept D7 and have been loving it. I've been using it with headphones or connected to the TV for the most part and have just started to use it for some audio recordings and realised the sound from the inbuilt speakers is terrible. Also, it seems to falter a bit when listening to music. I compared it to my old Acer Aspire V and the sound on that is far superior even though it is about 8 years old, was a lot cheaper, and much lower spec in general. The sound is very tinny and is not as high or clear as my Acer aspire. Surely this is a fault? I would expect this machine to have superior sound to the old ones - especially since great sound was something mentioned on the product promo page. Honestly, listening to music on it is little more satisfying than listening to it on the lousdspeaker on my mobile phone.
