I have installed both in rather large rooms and there are a couple of differences. For instance, although the Salons have multiple drivers recreating the midrange, sonically there's little difference between the two speakers. Some argue that midrange purity is better in the Studios, I'd agree, but with conditions. If you're sitting close to the speakers - less than 12 feet way - there does appear to be a better sonic image with the Studios. Beyond that, the gap narrows quickly. Bass response is also very similar. Of course the Salons can go down deeper, but the Studios present bass with identical weight, clarity and musicallity. You also mentioned tweeter level. Yes, the Salons are positioned a little high, but their wide dispersement design compensates for their height. Additionally, I have found most speaker tweeters are too low, especially for home theater where tiered seating is installed. I will tell you the same thing I tell my customers. Independently, both the Studios and Salons represent what is possibly the highest level of achievement in speakers. The bargain here is really the Studios. It's 98% of the Salons, but if you have the means and are going to ask what if everytime you play your system, get the Salons because trading up can be expensive.
