Hi was wondering if anyone had any thoughts on the Wharfedale DFS (specifically 18) vs. the Eltax HT2 as bipoles for rear wall surrounds? I want to try out some bipoles and I can get either pretty cheap, but didn't know if one was better than the other (I'm guessing the Wharfedales have a better reputation)? Currently I use a B&W M1 (2nd gen) 5.1 setup (the .1 is an SVS SB1000). As my sofa is right up against the back wall the surround B&W M1s are angled in but I don't really get an enveloping surround sound (it all very directional). Hence I'm looking at a bipole solution for the back wall and then may use the spare M1s for atmos duty once I upgrade my AV amp. Anyone any thoughts on either of the 2 I suggested and whether they'll be OK with the B&W M1s? Many thanks !
