The Montego II Quadzilla is a PCI sound card from Voyetra Turtle Beach, built on the Aureal Vortex 2 chipset. Released in 1999, it brings A3D 2.0 positional audio and wavetracing to the PC, along with quad speaker output and S/PDIF digital out via a breakout bracket. At $99, it undercuts many competitors while offering a rich software bundle, including Voyetra's Audio Station 32, MIDI Orchestrator, and a demo of Star Wars X-Wing Alliance. The card targets gamers seeking immersive 3D sound in titles like Half-Life, Unreal, and Sin, but its dependence on A3D support limits its reach compared to Creative's EAX ecosystem. Installation is straightforward under Windows 95/98, with solid NT 4.0 support, though A3D is not available on NT. Known driver issues, including a squelching bug in Unreal, reflect growing pains of the Vortex 2 platform. The Quadzilla positions itself as the feature-rich choice for early adopters of wavetracing technology, while the breakout bracket addresses the shortcomings of earlier OEM-only Vortex 2 cards.
