Hi Mark,<br /><br />Thank you for taking a few moments to review the Samsung HW-C47M Soundbar.<br /><br />If you would like louder (or softer) bass from your subwoofer, you can adjust the level by rocking the WOOFER button on the soundbar remote, and then adjusting the level from -6 to &#43;6. To set the subwoofer volume level to 0, press the button in.<br /><br />You can adjust the Treble and Bass by pressing the TONE CONTROL button then use the UP/DOWN buttons to change the levels between -6 to &#43;6.<br /><br />For precise audio adjustments, you can use the 7-band frequency equalizer to optimize the sound for your room acoustics by pressing and holding the SOUND CONTROL button for about 5 seconds, make sure you also set the SOUND MODE to STANDARD.<br /><br />If you need more help, Samsung is here for you.
