N8D let me know about this speaker test done by TheBlackBerryGuy comparing the speakers on the Tour to the Bold, Storm, & 8900 Curve. It sounds really close and the creator has no stated opinion but I think the Tour and Bold get the top rating for speakers. I think the Bold has the best speaker of any BlackBerry currently but the Tour is pretty close.
Check it out for yourself below and let me know what you think! This is the first comparison I have seen about the BlackBerryGuy in quite awhile and its pretty good since not everybody has all 4 devices side by side.
