    Awesome

    The KEF Q250 center channel is fantastic! It blends so seamlessly with my KEF R3s and the rest of my surround setup that everything just feels perfectly balanced. Dialogue is crystal clear, and it adds such depth to the whole experience. Whether it’s music or movies, the Q250 really brings everything together—couldn’t be happier with how well it fits into my system!

    Junk

    Speaker shell tore after turning it up once. Now it rattles like a snake sounds terrible! Garbage

    Great value. Great match to existing KEF speakers

    This replaced an older and cheaper center speaker. This fitted exactly into the space I have so a bigger speaker wasn’t an option. It’s sounds great. Vocals are clear and overall it has made a useful improvement to the overall sound quality. The main left and right speakers are vintage KEF floor standers and this speaker seems like an ideal match. Recommended One note of caution is that this doesn’t come with a grill cover and covers are impossible to find. I think KEF no longer makes them.
