Hello everyone, first-time poster here!\n\nRecently I bought Def Tech bp9080 floor speakers and I am running them on my Yamaha RX-V675. I know my receiver is not a high-end unit and that I will have to upgrade it eventually. Right now I have only hooked up these two speakers to the receiver with a speaker wire (monster cables). They work and sound great!\n\nMy speaker settings are: Speakers - Large, Woofer - No\/OFF\n\nHowever, the bp9080 speakers have built-in powered subwoofers and have LFE input ports. My receiver has two LFE output ports. When I add the LFE cables into the mix, my receiver shuts off right away (regardless of volume level). Anything above muted sound causes the receiver to shut off. \n\nSpeaker settings are: Speakers - small, woofer - Yes\/ON. Double Bass - OFF\n\nWhat am I doing wrong? The weird thing is that if one of the speakers (either left or right) is hooked up with the LFE connection everything works fine. The moment I add the second speaker everything shuts down. \n\nDefTech customer service said my receiver is summing the sound levels from the speaker wire and the LFE cable and is recognizing it as a short, so it shuts off as a protection. The place I bought the speakers from said my receiver sucks and I need at least 140-150W per channel to run these towers - anything below that won't work... but they sound awesome right now, and how's that related to the LFE signal? I am super confused. \n\nIs there any advantage of running these speakers with LFE vs only a speaker wire? Would I see any sound improvements?\n\nThoughts?
