hi guy's, not to interupt,yet i have been reading, couldn,t resist, as my proble is long, and driving me nut,s, i shall try to shorten thing's,first art of my equipment, starting with a yamaha rx-v2095, i have a very large rectangular room, i have 6 sub's, like a fool i keep buying, instead of solving problem, wich is, i'm getting no lfe, i have tested each sub alone differant music ect. differant cables all new, as my sub's except one, come to think of it, i'm not sure it ever played, so it's not the sub's,i supposed i a'm confused as to why on my on screen menu on remote, lfe has no + out only 0db to -20 db, as stated in manual, this is an older unit, however is pretty up to date, other than wify ect., i purchaced four monoprice msu-122bl 12" budget sub's, i have those daisy chained, as they come equiped with line out jack's, the manual did not say anything about them, so, i went online to monoprice, they list them as intended to chain other sub's to, this maybe ok, maybe not, just thought save wye's and cable, then i purchased a jbl es250p, better lot's more power, yet, not getting it, i even hooked it up alone, the wall's should be quakin, everytime something like this happen's, it's usually my fault,like tinkering with that extensive menu?, but back when i purchesed it, i had it installed by store tec. yet all those years i don't recal the sub, back then i didn't know what to listen for, unlike you audiofiles, i just bought and said put it in, now i'm just learning how to work it, as it's still like new, not used much,the jbl sub, wont even come of red=stand by to green=signal detected amp on, unless i go to menu and choose, lfe/mains and sub's,then light comes on, stay's on,signal or not,plus it does not have the lfe/sub sound, just a cheap mid bass thump,every reveiw iv'e read on the jbl are great,so it could be me, but i don't know what else to do but ask for help, has anyone had a simular problem? or any suggestion's on testing, thank's, i know this was lengthly but perhap's we ca narrow it down, thank's for any responce one more thing, even though the manufature, of the monoprise suggest's using the line out's on their sub's, how would you guy's do it, use wye's at the source, not chain?, but remember, i did unhook all but the single jbl, direct to reciever, still not much HELP
