I just assumed that the 4i will have more power but I guess maybe there is more bass also I don't know. But both might not be that noticeable on the bass and just the 4i will be louder since they are 40 watts instead of 30 watts total power.
I'm sure someone that has had the opportunity to listen to both will confirm what I said in my previous post.
The larger cabinet and LF driver size of the i4 will mean an extended low frequency range compared to the i3. This goes without saying.
And the audible gain of the i4 over the i3 is about 1.2dB.
