hi all. just got a pair of klipsch rp160ms, to replace my polk towers. also got a pb1000. so i have 2 subs for now until the jbl finally gives up the ghost. (humming) figuring out speaker placement, about 22" from floor to bottom of speakers puts the tweeters of LCR close to ear level. looking at ridiculously priced particle board and ugly metal stands. may just build my own. then i wondered if i could wall mount them directly above the subs on both sides. (both subs are in front on either side of table thing...limited placement for them) would there be any kind of imaging issues or resonance weirdness with speakers a few inches directly above subs? obviously i could try it & see what it would sound like, but before buying wall mounts, drilling holes in walls etc, i thought id ask if anyone has a setup like that. thanks.
