What We Think

L.R. Bagg's new loudspeaker design is unlike anything I've heard before--it fills the room with an even, detailed sound. It has a remarkably warm and realistic quality which is very difficult to find in acoustic amps, and it produces this same richness and clarity at low volumes. The A-Ref offers plenty of headroom, too, and the notch filter allows for easy feedback control if needed. The EQ is detailed and I was able to quickly find settings for beautiful tone on a McPherson, a Lowden, and a Santa Cruz Tony Rice Model without much trouble. This is an amplifier that could change the game for many acoustic rigs out there--you must try it for yourself to believe it!

Manufacturer's Description from L.R. Baggs

The Acoustic Reference Amplifier, a product of three years’ intensive development, blends cutting edge loudspeaker design, analog and digital circuit technology and industrial design to redefine the way that acoustic guitar and vocals should be amplified.

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.

Wrap all this technology up in a beautiful and durable lightweight enclosure with natural wood sides and an innovative handle and you’ve got a true tour de force and object of desire. If it all sounds too good to be true, we invite you to head to your dealer and take one for a test drive. We guarantee you’ll have to have one.


Balanced Mode Radiator – super wide full frequency coverage eliminates the “sweet spot” and fills every corner of the room for the same rich listening experience for everyone.


Conventional Loudspeaker – high frequency coverage is very limited and “beamy,” requiring listener to be in the “sweet spot” for the full experience.
