3-way bookshelf speaker​
The Q Concerto Meta HiFi speaker is the largest in our Q Series bookshelf speaker collection. Paying tribute to the original 1969 Concerto, which was our first 3-way standmount speaker, this modernised version delivers professional high-end audio quality. Thanks to its 3-way design and Metamaterial Absorption Technology (MAT™), this wired speaker is sure to deliver high-fidelity performance.
