Considering most all the scanners have bottom mounted speakers. Many of us put rubber feet on the bottom to elevate the the scanner to give the speaker room to breath so to speak. But the typical feet are only about 3/8" tall. I've resorted to external speakers for all my scanners. However I took delivery the other day on a new BCD536HP and I didn't have any extra speakers. ( I have to stop selling stuff!)
As a very temporary measure I found a very simple, free solution and it worked pretty well! I took a standard 3X5 index card and folded it in half, like a 'V'. I inserted the card under the scanner from the back with the open side of the 'V' facing forward and being careful to insert it just a little so as not to block the speaker so that the card acts like a reflector to direct more sound out from under the front of the scanner. It actually helped!
