No idea, but if you plan on mainly listening to Big Punisher through the speakers, they both have specs that indicate they'll do bass well enough.

What does "mm" and "nn" means?

Both speakers have their own strengths - Rockets are more forgiving, meaning if you throw any records (good or bad) at the Rockets, then they will sound 80% good all the time.

Song Tower are more accurate, meaning, if you throw good records at them, they will sound 90% good. And bad records will sound 70% good.

Since you've spent your money, my advice is, stop stressing yourself out, you've come a long way deciding on what speaker to buy, now it's time to just enjoy the music.
