This is the speaker set specifications:
Satellites: 48 watts RMS (2 x 8 W front, 16 W center, 2 x 8 W rear)
Subwoofer: 27 watts RMS
The speakers seem fine but the subwoofer is too tame for me (although it surprised me for 27 W, very impressive!)
I only use the system whilst connected to the PC.
I have a budget of around £80 for, basically, more bass.
What are my options?
