Attention Past & Future ResoNix Sound Solutions Customers!

While we are always available to support our customers and potential customers on their sound treatment journey via phone, email, or even text, we are always in an effort to constantly expand our ways to serve our customers, we have created a private Facebook group specifically for ResoNix customers. In this private group we offer direct, one-on-one help (even for subjects other than sound treatment), post helpful write-ups, post any current and future discount codes exclusively for group members, show current product designs and request feedback from members, post private how-to videos regarding products we sell at ResoNix (and even ones we don’t)!

The only requirement is that you be a ResoNix customer. That’s it! (sample kits not included). When joining the group, you must have your order or invoice number ready to post it into one of the group admission questions as proof of being a customer. Without an order or invoice number, Facebook will automatically filter it and decline your request to join. If you do not have your original order email with the order number, feel free to reach out and we can get it for you.
