I just received my Sierra Towers (RAAL) last week and my initial impression is that I'm incredibly impressed. I'm coming from a pair of 1992 Mirage M3si's, so the only thing lacking is the deeper bass from the passive 10" woofers. I have a Rythmik F15HP on it's way right now to remedy that, but the bass is just fine for listening at anything under high volume. They're also much easier to drive considering they are about 7ish dB more efficient over the Mirage depending on which specs you're looking at. These live in one half of my basement (about 3500 cu.ft. on that side) and at the level my wife and I listen, which is as loud as we can go without pain over hours of listening, these things can bring my house down. The basement ceiling tiles and insulation are gone while I'm in the middle of replacing them, and in this state, the volume on the second floor would prevent someone from sleeping as it's about as loud as a low-volume television in a closed room. Our baby didn't wake up but she sleeps through anything.
Music-wise we run the gamut from Steely Dan, David Bowie, Morrissey, Pearl Jam, Jeff Beck, SRV, Rickie Lee Jones, and Supertramp to whatever 90s and 2000s R&B and Rap my wife puts on which I can't recognize but it makes her happy and she can dance around. With all that said we almost exclusively listen to studio recordings so I can't comment on full-blown orchestral offerings. With that in mind, the reproduction has been astonishing. We're looking forward to integrating the sub next weekend.
