Our take on the PRO-X 6.5" Mid-Range Loudspeaker

The DS18 PRO-X6.4BM is a 6.5-inch midrange loudspeaker built for loud, punchy mids in car audio, motorcycle and competition builds. It handles 250W RMS (500W max) at 4 ohms with 95dB sensitivity, so it plays loud on modest amplifier power. Its 100Hz–10kHz range covers vocals and instruments but not deep bass, so it works as part of a system with a subwoofer rather than alone. Buyers rate it highly for output and clarity; the trade-offs are a narrow low end and the need for real amplification and crossover tuning.
