Bache Audio Sofia 104

The biggest and newest addition to our Sofia floorstanding speaker line. We use the same quasi-coaxial technology as found in our compact Sofia-101 bookshelf and midsize Sofia-102 floorstanders. In addition, we’ve added a 10” fiber wood cone woofer for extended low-frequency performance.

Like all other models in the Sofia line, this speaker design delivers an extremely smooth response both on and off-axis, while avoiding the phase and lobbing issues typically found in standard 2-way designs.

They also outperform single full-range drivers — even those with a whizzer cone intended to improve high-frequency reproduction.
