When designing this product, we felt that the name “guitar Amp” did not fully capture the capabilities of this product. In fact, we found
that we enjoyed listening to all kinds of live and recorded music through it. To us, it felt much more like a reference monitor than a guitar
amp. We began to test the quality by comparing it to audiophile speakers that are used in recording studios. each time, the sound of this
product really grabbed us as having a quality much like a very good reference system. so, we decided we should call it what it really is
- an Acoustic Reference Amplifier.

An important factor in the Acoustic Reference Amplifier is the visual design. We spent countless
hours talking about how to design a product to fit alongside your coffee table as well as being a
high profile and durable stage feature. We wanted to have the feel of new, cutting edge design and
combine it with the feel of acoustic instruments.
This led us to the rugged “structural Foam” casing that is made out of the same material that flight
cases are made with. The wood panels are designed with a slight “retro” look but with a touch of
modern flair. The aluminum handle was designed to get rid of the old rubber-strap amp handle and
have the handle integrated into the overall design. The other metal portions such as the steel grill
and the aluminum back panel are durable features to protect the components inside.
At the heart of the amplifier is a patented Balanced Mode Radiator. The BMR is a new type of loudspeaker that
has its world debut in the Acoustic Reference Amplifier. It creates and radiates sound in a fundamentally
different and better way. This groundbreaking innovation is the brainchild of the eminent speaker
designer Dr. graham Bank and was specifically adapted for acoustic guitar in collaboration with our
engineers. exclusive to lR Baggs, this fully custom flat 8” honeycomb-diaphragm speaker employs
a single 2” voice coil to generate a 140-degree wide full range conical sound field with a clean sPl
of 108 dB. As all frequencies are generated by the one flat diaphragm, there are no crossovers or
time distortions to smear and muddy the sound. Harmonics align naturally with fundamentals, so
clarity and detail are breathtaking but without the normal harshness or annoying directionality
of a multi-driver system.
unlike conventional multi-driver loudspeakers, the new BMR design combines the best features of
pistonic behavior, for low frequency control, with the best features of bending wave sound creation
for wide high frequency dispersion. This behavior closely mimics the way a guitar top generates
sound. This organic connection between the guitar and the BMR speaker makes it ideal for bringing the
voice of the acoustic guitar to life.
