DESCRIPTION
The EVM®10M is a 10-inch speaker designed
for professional, high-level, high-quality guitar
and mid-range amplification systems. Used full
range, the EVM®10M’s frequency response is
specifically tailored for brilliant lead guitar performance. The EVM®10M incorporates manufacturing refinements that have improved performance. Power capacity is 300 watts per EIA
RS-426-A 1980. The Power-Handling section
describes these ratings in detail. This improvement in the EVM®10M’s already highly regarded
reliability has been made without changing its
other performance characteristics in any way.
The construction of the EVM®10M features a
low-mass edgewound voice coil on a rugged
laminated polyimide coil form, driven by our
large, 16-lb magnetic structure. Also featured
are a heavy-duty curvilinear cone and a fatigueresistant cone suspension. Both the coil and
magnetic structure are vented. All of this is
packaged around a robust, eight-spoke, diecast
aluminum frame.
The EVM®10M may be front- or rear-mounted
without an adapter. The optional SMH-1 speaker
mounting kit facilitates front mounting (see Installation section).
RECOMMENDED ENCLOSURES
Typical Enclosures
The EVM®10M 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 EVM®10M 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.
Sealed enclosures are also very commonly
used for guitar—for some very good reasons.
Like open-backed enclosures, sealed enclosures are very easy to design and build. The
EVM®10M performs very well in virtually any
possible sealed enclosure, from 0.5 to 3.0 cubic
feet (internal volume). The enclosure size makes
very little difference within this range. EVM®10M
performance in sealed enclosures is tight and
punchy. The overall performance is very focused.
