Designed to provide full range performance in medium to larger sized spaces, the Grand Callas steps up over the Callas Diva with an additional 8” bass driver and bigger enclosure to be able to pressurize larger spaces. Like its smaller siblings, these speakers are fine furniture with stunning lacquered walnut or mahogany veneer on the curved sides and leather on the front baffle. Build quality and finish is absolutely first rate. Note: the stock photos do not remotely do them justice.
