Availability: In stock
Manufacturer: Opera Loudspeakers

The new Grand Callas is a three-way floorstanding speaker that replaces the previous model with the same name. Though it shares the same name as its predecessor, it has been completely redesigned from top to bottom; making it more comparable to Opera's previous flagship, the Tebaldi. Where the Tebaldi was large and could be difficult to place, the new Grand Callas has a much smaller footprint and is less-sensitive to placement.

This low-range loaded reflex design uses two 8” long-throw woofers, a 7" annealed polypropylene midrange and a 1" Scanspeak 9700 tweeter. The diffuser is complemented by a rear radiation system that uses two tweeters configured as a natural dipole. These rear-firing drivers increase the ambient sound, giving depth and substance to the musical performance.

Key Features:

  • Floorstanding speaker design in two wood finishes
  • Three-way configuration
  • Mid-range woofer has a polypropylene re-cooked cone and phase plug
  • Scanspeak tweeter handles high power without ferrofluid for greater detail
  • Rear-firing radiation system diffuses sound to improve ambient sound
  • Bi-wirable
  • Finished in high-quality wood and leather
  • Support for spikes or wheels
