I somewhat recently acquired a pair of Ren 90s for my father who was fairly jealous after I showed him my Sigmas, though some time after handing them over to him he let me know that he thought they were quite underwhelming. I think that his room isn't very speaker friendly (lots of hard surfaces and fairly small) so I brought them back to my house to give them a try with my amp, and considering how similar they are to the Sigmas I had assumed that they would live right at home in my room right where the Sigmas normally sit. After getting some help lugging my casket sized primaries out of the room I plopped the Rens in their spots and... well I was completely underwhelmed initially. While they certainly had the same depth and musicality of the Sigmas, their image was vague at best. I've been toying around with their positioning for the last couple of days and I can't seem to get it focused anywhere near as well as the Sigmas are even when they aren't set optimally. I even tried my project pair of Magnepan 1.6QRs and without even fine tuning their positioning they immediately had a much clearer and more precise image. I know that the Rens are capable of more, well I assume so anyway based on the prevailing opinions of them out there on the net. Can anyone help give me some tips to proper positioning for these things? My Sigmas are happiest when I have them about 3 feet from the back wall, 4 feet from the sides, and with 0 toe in. They sit 10.5 feet apart cone to cone which is the same distance that each one is from the my sitting position. I tried the Rens in the same position with 0 toe, a little toe, pointed straight at me, and in every case the imaging that I'm hoping for just isn't there. I'm not expecting them to project the vocals into the center of the room or do anything crazy but the best I've been able to get is a feeling that instruments aren't coming from the speakers and are somewhere in a fog of sound between them, but nothing even close to precise. Any ideas?
