First let me say that I hope you bought a pair of used "broken in" ones? When I first received them I put them in a 11x11x8H room and they had lesser bass response,bright sounding tweeters,very detailed,good with vocals,and no finicky placement. They started sounding better at 60hrs. of break in, definitely better Bass and thump at 100hrs. I then moved them into a 13W x12H x13L?? room. This room actually only has 3 walls so technically the length is open and much longer. They now have about 140hrs. on them and they sound beautiful on jazz music,instruments,vocals,keb mo, nora jones,etc. Tweeters are finally SWEET sounding,mid range is GREAT, with large musical soundstage. However putting them in this larger "open" room has killed the bass! Actual bass instument sounds somewhat true and natural but NO punch,thump,or boom from other types of music, NONE. If I keep them in this room I think I'll get a subwoofer. Nothing to shake the house or anything, just some thump. BTW, I'm using 8 guage DIY speaker cables with no bi-wiring.
