L-ACOUSTICS specifications are based on measurement procedures which produce unbiased results and allow for realistic performance prediction and simulation.

Some of these specifications will appear very conservative when compared with other manufacturer’s specifications. All measurements are conducted under free

field conditions and scaled to a 1 m reference distance unless otherwise indicated.

FRONT LLC setting provides a 3 dB low frequency contour under freefield conditions

X-OVER LLC setting applies a 125 Hz high pass filter

Components

LF 1 x 8'' weather resistant loudspeaker (2” voice coil)

HF 1 x 1'' exit compression driver (titanium diaphragm,coaxial assembly)

Sensitivity is the average SPL measured over the com-

ponent’s rated bandwidth

Power rating displays the long term RMS voltage handling

using pink noise with a 6 dB crest factor over the compo-

nent’s rated bandwidth

Directivity is averaged over the 1-10 kHz range

System output gives the unweighted SPL output of the sys-

The L-ACOUSTICS

MTD108a and its

accompanying analog controller provide a

highly versatile system that is designed

for distributed sound reinforcement.

Intended for medium-scale touring, sub-

hire or fixed installation, the MTD108a

features extremely compact dimensions

and highly flexible packaging while bene-

fiting from the economy, packaging and

"plug and play" ease of use afforded by

it's companion MTD108LLCa stereo line

level analog controller.

The MTD108a is a passive 2-way loud-

speaker enclosure containing a 1" exit

compression driver that is loaded by the

8" loudspeaker in a coaxial configuration.

Advantages of the coaxial approach inclu-

de: single point source radiation and

excellent phase response, total wavefront

coherency at all frequencies and axi-sym-

metrical directivity that produces identi-

cal horizontal and vertical coverage.

Coaxial design also provides LF/HF super-

imposed dispersion characteristics that

are free of polar lobing effects typical of

traditional horn and woofer combina-

tions. The end result is natural, studio

monitor level sound quality, ideal for

proximity use and perfectly matching

semi-reverberant environments.

The MTD108a is designed for distribu-

ted sound reinforcement in theatre,

corporate, restaurant, retail, club, or

television applications. Examples of

distributed systems include delay rings

for large-scale installations, surround

effects channels for theatre or multimedia,

distributed reinforcement for sports

venues and delays for speech reinforce-

ment. The compact format of the

MTD108a also allows for visually-discre-

te installation in front fill or underbalcony

applications.

Due to its compact, wedge-shaped

format, axi-symmetrical directivity and

full range passive design, the MTD108a is

equally useful as a cost-effective, low pro-

file, high-efficiency floor monitor. Dual

trapezoidal construction allows the

MTD108a to be used for either short- or

long-throw monitoring and with additio-

nal subwoofers such as the SB115, SB118

or SB218, the MTD108a is suitable for

drum monitoring applications.

Sonic quality was an important design

criterion for the MTD108a and its

frequency response is exceptionally flat,

providing superb fidelity and optimum

speech intelligibility. Given this fidelity and

its dynamic response, the MTD108a is

effective in situations that are typically

unaccustomed to sound reinforcement, in

particular, for classical music and opera

where high quality sound reinforcement

is essential.

The L-ACOUSTICS MTD108LLCa is a

dedicated stereo analog controller that

provides optimum processing and sense

return protection for the MTD108a.

Front panel design allows the controller to

function as a patch panel, providing an

ergonomic, cost-effective solution for

amplifier rack packaging.

A pole mount socket is included as stan-

dard and the MTD108a is Omnimount-

ready. An adjustable U-bracket is avai-

lable as an optional rigging accessory for

ceiling, wall, scaffold or truss mounting.
