Affordable Philharmonic Speakers
When I asked the price of the floorstanding Philharmonic 3 (front), which I had heard producing a big sound with extended low frequencies on a recording of Copland's Fanfare for the Common Man, driven by an AVA amplifier, I was expecting an answer of the usual "many thousands of dollars." Instead, I was told the speaker costs just $2800/pair!
That is a lot of speaker for the money. The 3 combines a Raal 10D ribbon tweeter crossing over at 2900Hz to a BG Neo 8 planar-magnetic driver in an open-back enclosure. The bottom enclosure, isolated from the upper with a 1/25" vibration-absorbing pad, handles frequencies below 650Hz and loads an 8" Scanspeak Revelator woofer with a transmission line. Less-expensive versions of the speaker, the Philharmonic 1 and 2, differ only in the drive-units used. Check out www.philharmonicaudio.com for the full technical story on these speakers.
