Lead Guitar

Loudspeaker

▪ Classic lead guitar performance—full, precise

overdriven tones and unrivaled clean tones

▪ Ideal upgrade speaker

▪ 200 watts long-term power capacity

▪ Edge-wound flat aluminum wire for maximum output

and bullet proof reliability

▪ 100 dB sensitivity

The EVM12L loudspeaker is a 12-inch speaker

designed for professional, high-level, high-quality

guitar amplification systems. Used full range, the

EVM12L loudspeaker’s frequency response is

specifically tailored for brilliant lead guitar

performance and classic guitar tones. The EVM12L

loudspeaker incorporates manufacturing refinements

that have improved performance. Power capacity is

200 watts per EIA RS-426-A 1980. The Power-Handling

section describes these ratings in detail. This

improvement in the EVM12L loudspeaker’s already

highly regarded reliability has been made without

changing its other performance characteristics in any

way.

The construction of the EVM12L loudspeaker 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 fatigue resistant cone

suspension. Both the coil and magnetic structure are

vented. All of this is packaged around a robust, eight-

spoke, die cast aluminum frame.

The EVM12L loudspeaker may be front- or rear-

mounted without an adapter.

| EVM12L 12" Classic Lead Guitar Loudspeaker 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 EVM12L loudspeaker performs very well in virtually any possible sealed enclosure, from 0.9 to 3.0 ft3 (internal volume). The enclosure size makes very little difference within this range. EVM12L loudspeaker performance in sealed enclosures is tight and punchy. The low end is fast and solid.

| EVM12L 12" Classic Lead Guitar Loudspeaker Electrical Connections Use no. 18 or larger stranded wire to connect the loudspeaker to the input panel connector. POWER-HANDLING In musical instrument systems, unlike sound reinforcement systems, it is advisable to use speakers that are rated for at least as much power as your amplifier output rating. It is also widely known that heavily overdriven tube amplifiers are usually capable of double their rated output power, and sometimes more.
