I should have listened to other 1 star reviews. I let the 5 star reviews convince me to roll the dice and that was a mistake. I have an Onkyo TX-NR 676 receiver and they work and don't transmit unless I have the subwoofer level set to +12dB and the volume set to at least 55 (which is pretty loud), and even at that volume there are occasional power outages. . To get a consistent signal, the volume needs to be at 60 or more, which loudly wakes up the neighbors. Needless to say I would not recommend this product.
