Short answer: choose between the Axiom ED150A and FBT Mitus 115A 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 ED150A. High-quality vendor data returns a 5.36 ideal-subwoofer preference score with 47Hz measured extension, matching the well-regarded ED120A’s asymmetric-coverage design in a 15-inch cabinet.
The case for the FBT Mitus 115A. Medium-quality vendor data returns a 4.87 ideal-subwoofer preference score, continuing the Mitus 112A’s B&C neodymium woofer and rotatable horn design in a 15-inch cabinet aimed at premium main-speaker use.
Important trade-offs. Axiom has a much smaller North American dealer and service network than JBL, Yamaha or QSC, and detailed coverage/weight figures were not confirmed in local data.
Buy the Axiom ED150A when its stated format, coverage, and system features fit the job better.
Buy the FBT Mitus 115A 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.
