System overview
RECOMMENDED ENCLOSURES
Typical Enclosures
The EVM12L loudspeaker will often be used to replace
inferior speakers in existing enclosures. Mechanical
and electrical characteristics are such that the
superior efficiency, sound quality and reliability of the
EVM12L loudspeaker will be realized in virtually any
sealed, vented (bass reflex) or open-backed enclosure.
Open-backed enclosures have been used for electric
guitars from the very beginning. Generally, they offer
very good performance in many situations. The sound
is often characterized as being open and having a full
mid-bass response. Although these enclosures are
often referred to as warm sounding, they do not have
an especially tight or solid low-end response. The
EVM12L loudspeaker’s performance in this type of
enclosure is considered world-class for many music
styles.
