For added convenience, the Q Acoustics 5090 Center Speakers come with a magnetic grille in a sleek black color. This allows for easy installation and removal of the grille, making it hassle-free to clean or customize the look of the speakers to suit your aesthetic preferences.


When it comes to performance, the Q Acoustics 5090 Center Speakers excel in several key areas. One of the standout features is their ability to accurately project dialogue in movies. The dedicated center channel design ensures that every word spoken on-screen is delivered with precision and clarity, allowing for an immersive cinematic experience. Whether you are watching action-packed blockbusters or dialogue-heavy dramas, these speakers will ensure that you catch every whisper and every shout.

Furthermore, the Q Acoustics 5090 Center Speakers excel at reproducing nuanced sound for art-house films. The mid/bass driver, featuring Q Acoustics' proprietary C3 Continuous Curved Cone™ technology, delivers exceptional detail and accuracy, allowing you to fully appreciate the intricacies of subtle soundscapes and delicate musical compositions.
