Just purchased 3 Sierra Horizons all with the RAAL tweeters. Will be using them as fronts across for AV system in main room. Really looking forward to hearing these with my old Mackie HRS 150 Sub. Will add in-wall surrounds and rears for this 7.1 system. Wish I could go with Ascend speakers all around but the in wall/in ceiling need prevents this. I am open to suggestions. Mostly, just want to say hello, and cannot wait to hear these babies!
