THE OBBLIGATO SERIES
Handcrafted Canadian excellence!
Any loudspeaker system that incorporates a
low frequency driver in the same enclosure
is an immediate compromise in acoustic
design. Interference by the woofer on the
overall performance of the tweeter and
midrange drivers can never be overcome.
Endless experiments by our own engineers to
eliminate this problem has confirmed the
fact that we must remove the low frequency
driver and place it in a separate enclosure.
This eliminates the problem of mechanical
resonance or feedback to the other drivers
in the system.
The listening environment poses the largest
problem for the reproduction of wide band
audio information. Below 50Hz, with
contemporary Hi Fi gear, in an average room,
the lower frequencies just fade away. They
disappear. This is due to the physical
limitations of the low frequency driver to
develop a similar acoustic output as the
other drivers in the system and of course
the room itself. The low frequency driver
requires much more power to achieve the same
output as the mid range or tweeter units.
This is an impossible task for the amplifier
that is driving the system. Angstrom
engineers solved this problem by adding an
amplifier to power the low frequency section
and designing an entirely new low frequency
transducer. The added flexibility of our
multi loudspeaker design ensures a totally
integrated sound presence in the listening
