5x7” Mid-Range Loudspeaker with Bullet
DS18’s PRO-X57.4BM is a heavy-duty 5x7” mid-range loudspeaker with bullet made for pure vocals and mids without distortion or drop-off at any volume. Rated at 175W RMS and 350W MAX at 4 ohms, this speaker brings clarity that cuts through chaos.
Massive Output
With a 94dB sensitivity rating, the PRO-X57.4BM gets loud easy, and its 100Hz–8kHz frequency response is the sweet spot for vocals, guitars, snares, and more. Paired with a sub, this speaker performs like a boss every time!
Pro-Level Construction
The oversized 1.5” CCAW voice coil is wound on a Kapton former, giving you high-temp resistance and long-term performance at full blast. Powered by a massive 20 oz ferrite magnet, this driver delivers aggressive midrange with razor-sharp control.
Focused Power with Aluminum Bullet
The aluminum bullet centers your sound and directs it with precision — perfect for motorcycles, UTVs, or open-cabin setups where you need to project sound far and LOUD!
Upgrade to the PRO-X57.4BM and experience mid-range in it’s purest form!
