Hi Kurt! The SWA-9100S is not compatible with the HW-Q800A. The correct rear speaker kit to pair with the HW-Q800A is the SWA-9500S which does not require any speaker wire. Check it out at the following link from Best Buy: https://www.bestbuy.com/site/samsung-2-0-2-channel-wireless-rear-speaker-kit-with-dolby-atmos-dtsx-black/6456115.p?skuId=6456115
