Amplifier Requirements
The DME-2181 contains two woofers which
are separately accessed via the 4-pin input
connector. There are two ways the drivers
may be wired:
1. Each driver may be connected to its own
separate amplifier channel. The
recommended power rating is 600-1,200
watts per channel into 8 ohms. The ampli-
fier channels must be identical, having the
same voltage gain and power rating.
2. The two drivers may be paralleled to one
amplifier channel. The speakers should be
paralleled at the amplifier, not at the cabi-
net. The recommended power rating is 1,200-
2,400 watts into 4 ohms.
DME-2181 speakers may be paralleled only
with other DME-2181 speakers if the am-
plifier is capable of delivering full power at
the lower impedances. The use of amplifi-
ers with lower power ratings is acceptable;
however, the full-power capabilities of the
DME speakers will not be realized. The use
of amplifiers with significantly higher power
ratings will generate maximum dynamic
range and fidelity, but care must be utilized
for longer duration signals, as mechanical
and thermal damage are possible in the sys-
tem. See owner’s manuals on various con-
trollers for appropriate settings.
Field Replacement
The DME-2181 was designed for expedient
field service. Removing the woofer bolts al-
lows the woofer to be easily removed. A
woofer failure will require replacement of
the entire driver.
The following replacement parts are avail-
able from the EVI Audio Service in
Straubing, Germany:
LF: Complete woofer: EV Part No. 818-2389.
