Short answer: choose between the Axiom ED80P and Martin Audio CDD8 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 Axiom ED80P. High-quality vendor data returns a 4.1 ideal-subwoofer preference score. A 1-inch aluminum-voice-coil compression driver pairs with the 8-inch woofer in a compact passive point-source cabinet aimed at fixed-install and portable use.
The case for the Martin Audio CDD8. Medium-quality vendor data shows a 3.4 ideal-subwoofer preference score. The coaxial Differential Dispersion driver gives point-source summation of the LF and HF sections for consistent coverage, and the ultra-compact enclosure mounts horizontally or vertically for on-wall installation use.
Important trade-offs. Being passive, it needs an external amplifier and crossover, and Axiom has a much smaller North American dealer and service network than JBL, Yamaha or QSC. The vendor measurement’s implied bass reach should be treated with some skepticism for a cabinet this compact. Being passive, it needs an external amplifier and crossover, and its compact on-wall design targets installed foreground music over full PA main duty.
Buy the Axiom ED80P when its stated format, coverage, and system features fit the job better.
Buy the Martin Audio CDD8 when its stated output, control, and deployment strengths better match the system.
The Martin Audio CDD8 is not a sound-quality pick. It sits near the bottom of the 15 8-inch two-way powered pa speakers; there are better options higher up.
