Hello Insomnia,<br /><br />Thank you for your purchase of the Samsung HW-Q990D Soundbar, I am sorry that you have experienced this issue with your Subwoofer.<br /><br />Please know, the maximum wireless signal distance between the soundbar and Subwoofer is about 33 feet. If there is a wall between the soundbar and the transmitter module, it may cause interference or the sound may not work at all, depending on the material in the wall. Finally, if a device that uses the same wireless frequency, such as a Wi-Fi router, is near the soundbar, interference may cause some sound interruption.<br /><br />Please also make sure your soundbar is updated to the latest firmware version featuring the latest connection improvements. Should you continue to experience issues with the sound occasionally dropping, you may want to try reconnecting the speakers manually; this will reset the connection.<br /><br />Samsung is committed to providing the best possible product experience, quality, and value, and we back this soundbar with a 1-year limited manufacturer&#39;s warranty.<br /><br />So that we can better assist you, please reach out to Samsung Support at<br /><br />1) 1-800-SAMSUNG (ask for Soundbars), 8 AM - 12 AM EST, 7 days a week. <br />2) LiveChat with an agent by clicking the ‘Support’ link on the Samsung website homepage.<br /><br />We hope to hear from you so we can work together to find a solution.<br /><br />~Samsung Solutions

Hi SyandJo,<br /><br />We appreciate you taking a few moments to review the HW-Q990D Samsung Soundbar. Please know there is a wide range of audio adjustments available to tune the sound to your liking.<br /><br />You can manually optimize your audio experience by pressing the SOUND CONTROL button (which looks like a gear), you can set the audio function such as Auto EQ, Spacefit sound, AVA, Voice Enhance mode, Night mode, Sync, Surround speaker mode, Virtual. The desired item can be adjusted using the Up/Down buttons. <br /><br />Alternatively, you can press and hold the SOUND CONTROL button for about 5 seconds to adjust the sound for each frequency band. 150Hz, 300Hz, 600Hz, 1.2kHz, 2.5kHz, 5kHz, and 10kHz are selectable using the Left/Right buttons and each can be adjusted to a setting between -6 to &#43;6 using the Up/Down buttons.<br /><br />You can try quickly optimizing the audio by pressing the SOUND MODE button on your remote, and then select the desired sound effect by choosing STANDARD, SURROUND SOUND, GAME, or ADAPTIVE SOUND.<br /><br />To control the volume of each speaker, press the CH LEVEL button on the provided remote. Then select CENTER LEVEL, SIDE LEVEL, WIDE LEVEL, FRONT TOP LEVEL, REAR LEVEL, or REAR TOP LEVEL. Once you find the channel you are looking for, adjust the volume between -6 to &#43;6 by using the Up/Down buttons. <br /><br />There are multiple ways to control the bass levels for your new Soundbar. <br /><br />1) Using the WOOFER button on the provided Soundbar remote. Use the woofer button by pushing forward or pulling backward on the button itself to adjust the bass levels between -12 or -6/&#43;6. If you want to reset the bass to 0 then push the button in. <br />2) When you press the TONE CONTROL button, you can adjust the treble or bass levels between -6/&#43;6.<br /><br />Alternatively, you can adjust all of these same settings and more within the SmartThings app. Download the app for your iOS or Android device and then connect your Soundbar to Wi-Fi. From here, you will be able to adjust all of the same settings as the provided remote, but with the added benefit of being able to see the changes on your smart device.<br /><br />If you’d like more help with settings, please know we’re here to help!
