Short answer: choose between the Martin Audio CDD10 and Wharfedale Pro Delta X10 for the deployment, not from the automatic ranking alone. Their driver format, power requirements, coverage, bass reach, output capability, and control features determine which is the more practical PA for a particular room or system.
The case for the Martin Audio CDD10. Medium-quality vendor data shows a 4.13 ideal-subwoofer preference score. The coaxial Differential Dispersion driver gives point-source summation of the LF and HF sections for consistent coverage, and the compact enclosure mounts horizontally or vertically for on-wall installation use.
The case for the Wharfedale Pro Delta X10. Built from 15mm birch plywood with a titanium-diaphragm compression driver, it can run full-range passive or switch to bi-amp mode for more control when paired with separate amplifiers, and its 300W continuous/1,200W peak handling is a genuine budget entry point for a 10-inch box.
Important trade-offs. Being passive, it needs an external amplifier and crossover, and its compact on-wall design targets installed foreground music over full PA main duty. Low-quality independent data shows a 1.49 ideal-subwoofer preference score with bass extension only to roughly 100Hz, the weakest measured result in this entire ranking; a subwoofer partner is effectively mandatory.
Buy the Martin Audio CDD10 when its stated format, coverage, and system features fit the job better.
Buy the Wharfedale Pro Delta X10 when its stated output, control, and deployment strengths better match the system.

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.
