The new Grand Callas model is a three-way floorstanding speaker that replaces the previous model with the same name. This new version has been completely redesigned from top to bottom. In fact, the performance of this new Grand Callas is at the same level as our classic Tebaldi model, but with a significant reduction in footprint, room placement flexibility and price.


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.

It’s obvious we wanted to keep the best features of both the previous Grand Callas and Tebaldi models in order to offer high-quality sound in a flexible loudspeaker system that is easily adaptable to all environments. In addition, we needed to continue the tradition of the Grand Callas aesthetically pleasing design that’s also a particularly good value for the money.

The back radiation system uses two tweeters that are connected as a natural dipole. The performance of this dipole is virtually indistinguishable from the triplet used on previous Grand Callas. The rear radiation pattern feeds the reflected field without interfering with the direct sound while preserving the accuracy of the transient response. The rear radiation balances the power response and increases what we call “brilliance," a quality related to the perception of sound details. Improving the perception of detail also means improving the perception of "space."

The front panel of the cabinet of the new Grand Callas was shaped to make near-field listening possible, even when the listener is only a meter and a half from the loudspeakers. That’s because the Grand Callas is truly flexible and adaptable to various situations such as when reverberation time is not particularly low. The other feature that contributes to the flexible is the ability to modify the response of the low frequencies with a flick of a simple switch.

You can also choose to block the reflex ducts, which gives you four possible configurations for the Grand Callas. The occlusion of the ducts could be necessary when the speaker needs to be placed close to room corners. This allows the listener to place the speakers in the room and then find a better frequency response by adjusting the ducts and using the switch, as opposed to trying to find the right room placement and positioning in advance. You can also adjust the speakers with two different responses when, for example, you need to place one speaker closer to the wall than the other.

The Grand Callas 2014 produces a sound stage that expands effortlessly in three dimensions, with an excellent impulse response. The power, dynamics and extension at low frequencies is among our finest achievements.
