Apertura Adamante

The Adamante is positioned as a bridge between the ONIRA and the flagship ENIGMA mkII. It captures the high-resolution detail and speed of the ENIGMA's ribbon tweeter while maintaining a saturated, color-intense midband that gives it a fuller, more energetic character than the smaller models.

With a sensitivity of 93dB and a 4Ω impedance, the Adamante is relatively efficient and doesn't require massive power to drive. However, because of their high resolution and complex crossover design, they perform best with high-quality amplification that can maintain control and tonal depth at lower volumes.

The hybrid loading system combines bass-reflex and acoustic line principles to manage low-frequency energy. This design helps the speakers deliver deep, authoritative bass without the muddiness or distortion often associated with traditional ported enclosures.

Apertura’s proprietary DRIM (Dual Ribbon Integrated Module) crossover is designed for precise frequency management between the mid-bass drivers and the ribbon tweeter. This ensures a seamless transition, preventing phase issues and resulting in a more coherent, natural soundstage.

While the Adamante is a substantial floorstanding speaker at 115cm tall and 52kg, its controlled dispersion and hybrid loading make it more versatile than many speakers of its size. However, you will need enough space to allow them to breathe; placing them too close to walls may overwhelm a small room with bass energy.

The composite enclosure is engineered to be incredibly rigid and inert, which minimizes unwanted cabinet vibrations. By reducing these resonances, the speaker ensures that the sound you hear is purely from the drivers, resulting in cleaner imaging and less coloration.
