The Q Install Professional Series is their entry-level range, but the performance surpasses what you would expect from an entry-level speaker. They use polypropylene bass drivers and silk dome pivoting tweeters to give a lively and engaging sound and the speakers are finished neatly with trimless magnetic grilles.
The range comprises a single stereo speaker with a 6.5" bass driver and dual tweeters for stereo sound reproduction, ideal for smaller rooms, a pair with 6.5" drivers which would suit medium-sized rooms, and a pair with 8" drivers best suited to larger rooms. The smaller models are available with either circular or square grilles.
The Qi80C is the most powerful of the professional in-ceiling range from Q Acoustics and offers a full and detailed sound from a relatively compact chassis. Using a 203mm bass driver and independent pivoting tweeter, it combines a smooth and sweet treble with a clear and well-defined bass response.
