I already know that I enjoy the Mad Dogs, and I was hoping the Alpha Dog would have a bit more bass. The reviews are all over the place with regards to this issue. I have not seen anything consistent stated about the bass quantity, just that it is linear, flat, neutral, etc. I don't see how the Alpha Dog bass can extend much over the Mad Dog, as it seems that the Mad Dog is flat as a pancake down to frequencies only a Blue Whale can hear.
Not to be rude, but I've already clarified this several times. I'll say it once more...the bass of the AD is APPRECIABLY better than that of the MD. It goes lower and with more weight and slam. If you like the bass on the MD, you'll love the bass on the AD. That is as clear as I can make it.
