Bad setup. Acoustic treatment, and EQ are your Rx.
Unfortunately too many times (most of the time) buyers think subs are as easy to set up as their mains. They are not, they are an order or magnitude more difficult and takes specialized knowledge, which anyone can learn, but it takes time.
Contact GIK Acoustics, and either get an auto-calibrating EQ for your sub, or get some one to properly integrate it for you.
