About the KV2 Audio ES Series Subwoofers
The KV2 Audio ES Series Subwoofers form the low-frequency component of the ES system, a compact and modular design in which all electronics and amplification are housed in the separate, portable EPAK 2500 or 2500R unit. A dedicated fourth amplifier channel within the EPAK powers the subwoofer, and a multi-position switch allows selection between subwoofer combinations for straightforward plug-and-play operation. The range includes the ES1.5, a lightweight single 15-inch enclosure; the ES1.8, a horn reflex single 18-inch subwoofer; and the ES2.5 and ES2.6, each a double 15-inch twin asymmetrical design available in four-Ohm or eight-Ohm versions respectively. Control electronics inside the EPAK continuously monitor and manage the relationship between amplifier and cabinet throughout the system.
KV2 Audio ES Series Subwoofers — buyer FAQs
What are the KV2 Audio ES Series Subwoofers and how do they fit into the ES system?
The KV2 Audio ES Series Subwoofers are the low-frequency cabinets in KV2's compact, modular ES system. They are passive enclosures powered by a dedicated fourth amplifier channel inside the separate EPAK 2500 or 2500R unit, which houses all electronics outboard. This arrangement keeps the cabinets lighter and easier to handle while a multi-position switch on the EPAK lets users select subwoofer combinations for plug-and-play operation.
What subwoofer models make up the ES Series range?
The ES Series includes three subwoofer options: the ES1.5, a lightweight single 15-inch enclosure; the ES1.8, a horn reflex single 18-inch cabinet; and the twin asymmetrical double 15-inch design available as the ES2.5 in four Ohm or the ES2.6 in eight Ohm. Each is designed to be driven by the EPAK 2500 or 2500R and selected via the control unit's multi-position switch.
Who makes the ES Series Subwoofers and where do they sit in the brand's output?
KV2 Audio is a professional audio manufacturer founded in 2002 and based in Milevsko, Czech Republic, known for loudspeakers, subwoofers and amplifiers with an emphasis on analogue signal processing for live sound and installation. The ES Series sits within that loudspeaker range as a scalable, modular system in which the subwoofers pair directly with the ES1.0 mid/high cabinet and the EPAK amplification unit to form a complete, self-optimising rig.
What should I check when buying a used KV2 Audio ES Series Subwoofer?
Confirm which specific model you are looking at, as the ES1.5, ES1.8, ES2.5 and ES2.6 differ in driver size, loading type and impedance. Check whether an EPAK 2500 or 2500R is included or already owned, since the subwoofer requires that unit to operate. Inspect the cabinet and driver for physical damage.
