      Thanks for commenting. While we are glad to hear that you like the good-looking design of our SA-CS9 115W 10” Active Subwoofer and great customer service of Best Buy, it is unfortunate to know that your unit had to be returned.

      We appreciate you and your feedback, and we are hoping you will consider Sony again in your future purchase.

      Thanks for the perfect star review!

      Best regards,
