Bass an no treble

[Natasha8778]

Infinity subwoofer is not playing treble it's low an bassy could it be my connection or speaker

 

[Kenton82]

It is a Subwoofer (sub-frequency, about 20–200 Hz for consumer products, and below 100 Hz for professional live sound ) . It will only produce low frequency sound, hence why you are only hearing bass (low frequency sound)

Hope this helps!
