The Quested LTX12 is a two-way active coaxial speaker from the LT Series, designed for surround and overhead (height) channels in cinema and immersive audio systems. The LT Series builds on Quested’s long experience in reference monitoring: the speakers are optimised for fast, clean transients and cinema clarity, and are designed to work together with Quested subwoofers.
In the coaxial design, a custom AMT (air motion transformer) high-frequency unit is placed at the centre of a bespoke 12″ (305 mm) mid-bass driver. Because both drivers radiate from one point, the speaker provides a consistent sound image even at short listening distances and from different angles – a key advantage for overhead and surround positions.
