Customer Reviews
I love the freedom to use this unit anywhere. The sound is great, we use the speakers during all of our events on the student union steps. WE use a variety of media and they all work well. I wanted you to know we are very satisfied with your product.

We just purchased a new Liberty sound system and it has been great. We have the option to plug it in or use the battery powered option which saves time and money on set-up. We at Bear Lakes have been using Anchor Audio systems for almost 12 years and our staff can’t be happier with the service and product we purchased.

I purchased a Liberty sound system from Anchor Audio after my Chain of Command saw the Liberty being used by another squadron in Qatar in the Persian Gulf. It stood head and shoulders above the system we were using at the time. Jealousy, plain and simple, was the motive for the purchase. Simply put, we have to have the best. We use the Liberty in an airplane hangar for large crowds, and the people in the back of crowd can hear every word.

I have owned my Anchor Liberty systems for over thirty years. These systems have continued to provide tremendous flexibility in holding outdoor venues in state fairs, athletic events, etc. Take it from one who holds several outdoor events each year, you can do no better than the Liberty Sound System. I do not see the purchase of a Liberty system as an expense, but rather a great investment.
