I recently bought an Onkyo TX-RN515 and some Polk RM705 speakers. I have been using a Rocketfish Universal Wireless Speaker Kit with my old configuration of a Teac receiver and Yamaha speakers with no problem. With the Onkyo and Polks I cannot get the rear speakers to work using the Rocketfish Wireless kit. Anybody know if there are compatibility problems with the Rocketfish Wireless Kit and the Onkyo TX-NR515 and/or the Polk RM705 speakers. Thanks all.
