Dell Small Business offers the Klipsch RSB-6 Bluetooth Soundbar with 6.5" Wireless Subwoofer bundled with a $150 Dell Gift Card for $399 with free shipping. Assuming you'll use the gift card, that's tied with yesterday's mention and the lowest price we could find by $150. (It's also tied with our Black Friday mention.) It features a 30Hz to 15kHz frequency response.
