Thank you for your help. I was using google to try to find out more and found a link to a Korean site with a a photo of a Beolab 4000 with its grill removed. http://www.hifiplaza.co.kr/porc_images/1243304564_y%20016.jpg It seems the tweeter is the same one onside the Beosound 1, however, the woofer is definitely not the same.

Just like to know more about the quality of drivers use these days.

Wonder what drivers B&O is using for their Besound 1? They don't seem to be from Seas, Vifa or Peerless. The following auction has some excellent photos of the Besound 1 with the drill removed: http://cgi.ebay.com/MINT-Bang-Olufsen-BeoSound-1-Flawless-Condition-B-O_W0QQitemZ260559461767QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item3caa8ddd87#ht_1604wt_919

Could someone tell me who make the drivers inside the Beosound 1. Don't think they are from Seas or Peerless.
