Hi there!
 
So I have this somewhat old Grundig Speaker system (20+ years) and I dug around the web to find the technical specs so I could figure out if I can improve over it.
 
I found that its has the following specs:
 
Music power - 2x30W
Nominal power - 2x20W
 
Power band width .................................................... 40 - 20,000Hz
Frequency response ............................................... 40 - 20,000Hz
Signal-to-noise ratio ........................................................... >= 75dB
Input sensitivity Aux ........................................................... 400mV
Speakers ................................................................................... 3 OHM
Headphones (ø 3.5mm) ............................................ 32OHM - 1000OHM
 
Now I have no clue what this actually means.
 
What is musical and nominal power? I researched but I couldn't understand the difference :|
 
Can I improve this in a non-expensive way? I find it lacks a bit on the bass department...
 
The speakers seem to have very low OHM, is this good or bad?
 
This is a 2 bookshelf speaker system that I have hooked up to my computer so I could use its speakers.
 
Thanks in advance!
