What to pair with stacked Large Advents


Got stacked advents as my front speakers. Have a Luxman R-117 receiver. This system is for music only. I play hard rock music. What would be a good pairing for rear speakers with this system?

No I didn't. Don't think that's expensive right? I would add another receiver to push the rears but don't have the room in the stereo cabinet. I added a channel selector and turn the volume down on the rears.
"Why not. For $300 find me a better sounding set of speakers and I'll buy them!" The Infinity Primus 363 They're easy to find, for around $300.00/pair. More efficient, more accurate, flatter response, cleaner mids, can play louder with much lower distortion figures, than ANY stacked pair of Advents. No nostalgia factor though(sorry).

Just good speakers, for the money.
