This feature, in my opinion, is the case's downfall. One of the reasons why I opted for the Macally. I love the newsy app for iPad. But when I had my iPad in the Apple case, I kept thinking the volume was on low when actually it was the case and its lack of speaker cut-outs that significantly decreased the volume.
I do not understand why Apple would not have proper cut-outs for the speakers.
I notice that you cut out some parts of the case. Has it worked for you? Do you suggest cutting some slots for the speakers?
I have replaced the apple case with the macally bookstand. But The apple case was the first one I bought and while I was looking for a replacement, I trimmed a portion of the case to allow me to use the iPad with the keyboard dock without removing it from the case. It worked great. If you haven't made a cut for the dock, then using a sharp hobby knife to cutout the speaker area would work just fine. But I wouldn't recommend doing both cuts. One or the other.
