Has any one heard both? Does anyone know how to read the graphs and tell which should excel in a music only system? thanks guys
also which other bookshelfs would you put in the league with these 2 for under $1000ish
I've heard both and both are very good. I heard the Sierra-1 several years ago, and the Philharmonitor recently.
I'd give the nod to the Philharmonitor because it's 6½" woofer (and cabinet) is larger than the Sierra's 5½" woofer, and is likely to produce better bass. Another reason is because I have a lot experience with several of Dennis's speaker designs and I know I like his results.
Another speaker in that price range and performance league is the
Salk SongSurround I. Dennis also designed it. All Salk speakers have an unsurpassed cabinet finish quality. Five different veneers are available at the standard price. The SongSurround I and the CAOW1 speakers are essentially identical. The SSI has a 4th order crossover and the CAOW1 has a 2nd order crossover. I've heard both, and I cannot tell the difference.
The only possible down side to the Philharmonitor is that it comes in one finish, as shown on the website.
EDIT: The lack of other finishes is a major reason how the price was kept low, allowing it to compete with those other two speakers.
