Know before you buy
THX Certified Ultra indicates that this speaker has passed rigorous testing to ensure it can deliver cinema-level volume and clarity in large rooms. It guarantees that the audio performance meets professional standards for high-output, low-distortion sound.
MAT acts as an acoustic black hole, absorbing 99% of the unwanted sound radiating from the rear of the driver. This significantly reduces distortion and results in a much purer, more natural sound profile.
Yes, the magnetic metal grille is designed to be paintable. You can finish it to match your wall color for a discreet, seamless look that blends into your room's decor.
The Uni-Q array places the tweeter in the acoustic center of the bass/midrange cone, allowing the sound to disperse evenly throughout the room. This creates a much wider 'sweet spot,' so everyone in the room hears consistent audio quality regardless of where they are sitting.
The 5.5 mm thick precision-machined aluminum baffle provides an incredibly rigid foundation for the drivers. This minimizes cabinet vibration, ensuring that the sound you hear is clean and free from the colorations caused by rattling or resonance.
Absolutely. With its four 6.5-inch hybrid aluminum bass drivers and THX Ultra certification, it is specifically engineered to handle the dynamic range and high output required for immersive, large-scale home theater experiences.
