Description
The KEF Q3 Meta Bookshelf Speaker is the largest of the bookshelf speakers in the Q Meta range. There are also floor-standers as well as a dedicated centre speaker and an upward-firing Dolby Atmos speaker. The Uni-Q driver is a two-way unit that includes a tweeter and bass/midrange driver in one.
This creates a single-point source for a smooth and accurate sound. Additionally, the current range now has MAT fitted which prevents sound from the tweeter from interfering with the other driver.
12th generation Uni-Q with MAT™ driver
The Uni-Q driver was developed by KEF to combine two drivers in one unit. A Uni-Q driver is used in the KEF Q3 Meta Bookshelf Speaker. The tweeter sits over the bass/midrange unit and creates a single-point source. Additionally, MAT has been fitted.
The metamaterial used has a maze-like structure that absorbs 99% of the sound coming from the rear of the tweeter. As a result, the sound has reduced distortion and a cleaner output Moreover, the single driver reduces timing errors.
About timing errors
Notably, many speakers have the tweeter and midrange unit some distance apart. As a result, the sound from each reaches the listener at slightly different times. Timing or phase errors can blur the sound. However, this is not a problem with the Uni-Q driver.
Enhanced crossover
Crossovers are used to split the audio signal into several parts to feed to each driver. This prevents bass frequencies from getting to the tweeter. KEF uses extensive listening tests and computer modeling to optimize the crossover components.
The component values depend on the drivers. Capacitors and inductors are used to form the filters. Long-life capacitors are used that will not drift in value with age.
Create a home cinema system with the KEF Meta Q range
The Q Meta range of speakers was designed with home cinema in mind. For example, a 5.1 system can be created by using either the bookshelf or tower speakers for the left and right channels. The rear surround channels can be created with either of the bookshelf speakers.
There is also a dedicated centre speaker. Moreover, the Q4 LCR speaker can be used in any position. It can also be wall-mounted. Lastly, for more complex Dolby Atmos systems there is an upward-firing speaker that can also be wall-mounted.
