Description
The ESM26 is a purpose built stage monitor with incredible clarity and presence, especially in the
all important vocal range. Incorporating two high quality 6” drivers and a 1.75” compression driver
on a 100x100 degree horn flare. The ESM26 utilises KV2’s revolutionary delay line technology for
optimum output and feedback rejection. A full width bass port along the bottom of the cabinet
couples with the floor to deliver bass response comparable to monitors twice its size. Under 400mm
wide this small monitor takes up minimal room on stage and is ideal for visually critical applications
like TV and theatre.

Description
The ESM12 is a full-range low profile 2-way, passive monitoring solution with a 12” trans-coil neo
woofer and the same 3” NVPD large format compression driver found in our flagship VHD products.
The ESM12 also features our revolutionary passive delay line, which dramatically reduces feedback.
Housed in a professional Baltic Birch cabinet, with a protective Polymer coating and heavy-duty grill,
the ESM12 can be utilized for FOH applications with the inclusion of a pole mount. Truly one of the
most impressive monitoring solutions on the market today, the ESM12 is available in left and right
configurations.

packed, the unit may be damaged.
