Short answer: these solve different problems. The CDD10 is a passive, on-wall coaxial box built for installed foreground music, while the ULT10 is a self-powered long-throw PA speaker. They rank #38 and #39 out of 42 10-inch powered PA speakers.
The CDD10 is a compact coaxial install speaker. Medium-quality vendor data shows a 4.13 ideal-subwoofer preference score, and its coaxial Differential Dispersion driver gives point-source summation of the LF and HF sections for consistent coverage. The enclosure mounts horizontally or vertically for on-wall use. Its own cons are direct: being passive it needs an external amplifier and crossover, and its compact on-wall design targets installed foreground music over full PA main duty.
The ULT10 is built for long-throw PA duty. A custom 10-inch driver with a 2.5-inch voice coil and a WorxAudio-designed rotatable Pivot X110 horn deliver a wide 110° x 50° dispersion pattern for even coverage and an ultra-long throw at 1,300W peak. Medium-quality vendor data shows a 3.2 ideal-subwoofer preference score, below most other actives in this ranking, and its own cons note it lacks an onboard mixer or app control.
Buy the ULT10 if you need a self-powered main speaker with wide, long-throw coverage for live sound.
Buy the CDD10 if you’re installing foreground music into a room and want a coaxial box that mounts flush on the wall.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
