For when only big sound will do, upgrade your in-ceiling speakers for even more power. Bigger rooms need bigger sound to fill them, and the Dynaudio Custom S4-C80 in-ceiling speaker certainly won’t leave larger spaces wanting. While it shares lots of what’s great about the smaller S4-C65 in its design – including its ability to rotate through 360 degrees to suit your room – it boasts a larger 20cm mid/bass driver for a more powerful sound that’ll go deeper and louder when it really counts. The higher frequencies are handled by the same excellent 28mm soft-dome tweeter as its smaller sibling too, which can also be pivoted to tailor the sound perfectly to your room.The bigger size of this speaker will require a little more room in your ceiling, but don’t worry. With a choice of round or square paintable grilles, the S4-C80 can stand out or blend in as much as you want it to.
