yeah they have plenty of these in stock. someone posted that there was only 20 left, so i called on the same day and the csr told me there were hundreds left. i called couple days later, and they still had hundreds, and he said don't worry about the speakers being sold out. i think they get constant shipments of these.
the sub was designed to be placed on the floor, below the desk. sure the sub isn't shielded, but that just means that the sub should not be placed on top of the desk next to the monitor.
the system sounds excellent overall. i'm very impressed by the bass this system generates. i don't think i can ever use this system to its full potential, without getting evicted from my apartment.
