About the Cassiopeia 6
The Apogee Acoustics Cassiopeia 6 is a discontinued HiFi speaker from Apogee Acoustics, a company known for its ribbon speaker technology. It combines a conventional 6.5-inch dynamic woofer for bass with a rotatable 4-inch ribbon tweeter for high frequencies, providing extended frequency response from below 40Hz to over 20kHz. Designed for high-fidelity audio reproduction, it requires a capable amplifier due to its demanding impedance and power needs. Apogee Acoustics ceased operations years ago, making these speakers no longer manufactured, with repairs available through specialized services.
