What is the US release date?

Asked by: chrantastic
Hi chrantastic, thanks for your inquiry and interest in the NB5540. Without knowing your zip code, using 11756 to find the closest retailer that is carrying the 320W 4.1ch Sound Bar Audio System With Wireless Subwoofer and Bluetooth Streaming the only retailer I could find was Micro Electronics which has 2 locations in Flushing and in Brooklyn. Use the "Where to Buy" feature on for their address and phone numbers. IFV
