Hertz CX 690 vs DCX 690.3: Which 6x9 Coaxial Speaker?

Quick answer

Choose the Hertz CX 690 Cento if you want premium materials and balanced tone; pick the DCX 690.3 Dieci for efficient, high-SPL performance at a lower price.

Which one should you buy?

• Sound quality first: If you're upgrading for better clarity and balanced tone, the CX 690's mica-reinforced cone and power handling make it the stronger choice, even if it costs more.
