Great Sub At Excellent Price!!!

By Anonymous

Comments about Harbinger HP118S Powered Subwoofer:

I recently purchase 2 of these Harbinger Subs to replace my QSC 151W. I needed lighter subs and an additional bass quick. So far, this sub has deliver in all aspects. Yes, QSC is great. I will miss my QSC, however, I am falling in love with this sub, and the price is a beauty.

Chest pounder

By Fearless1

from Northern CA

Comments about Harbinger HP118S Powered Subwoofer:

I use 2 subs with a pair QSC K12's. These hit you in the chest & will knock you down. QSC subs don't do that. Sound is clean & focused. The wheels have an innovative easy way of attaching & removal. The subs sound better than those costing twice as much. Only gripe is that these should come with poles and are quite heavy. I can afford to pay a lot more, but there is no need to when using your ears vs. your eyes looking at the brand.
