2-way Passive speaker

The ESD12 is a high-quality 2-way, passive full-range loudspeaker that provides unmatched clarity and definition in a simple, elegant package. The ESD12 utilizes a 12" Trans Coil woofer and the same 3" NVPD large format compression driver found in our flagship VHD products, which has one of the lowest distortion ratings on the planet. Combined with our unique delay line technology, the ESD12 delivers a beautifully balanced, phase-coherent, and accurate compact, 2-way passive solution that is adaptable to a wide range of applications.
