I don’t think the problem will be the speakers.. 127dB is a lot!
Do you own a mixer? Could you run audio through that before sending it to the speakers? Maybe try a different source? (Laptop soundcard? Phone?)
I also don’t know how a power adaptor can have “Ohms” and how this relates to the volume? Ohms are a measure of resistance – something that power adaptors generally don’t have. I also don’t know how plugging a different adaptor in can mean that the VU meters stop working?
I would try to borrow a friend’s S4 (or hire one for a day if you can) to see if that fixes the problem.
Other than that, an external soundcard would work fine. Personally I use a Focusrite Scarlett 2i4 for DJing from (I don’t use a controller) and love it – high audio ouptput, hardware controls, headphone jack on it (the 2i4 lets you have a separate headphone mix to the speakers whereas the 2i2 doesn’t).. it does all I need and more. An alternative is the Numark DJIO (a lot cheaper) which does the same job but does without the Mic Inputs, which aren’t needed for DJing..
I very much doubt there is anything wrong with the speakers. The best way to check would be to plug your phone into the back and see how loud it is then? The volume output from your phone should be lower than the output from your controller (slightly) but if it is louder then you know where the issue s.
