Harwood Acoustics AM 25 R AIR Motion Transformer, round Version

The Harwood Acoustics AM 25 is 4 Ohm and a pneumatic transducer is accurate, efficient, and ideal for applications ranging from compact 2-way to dedicated supertweeter. A powerful neodymium motor and "bellows-like" convoluted aluminum diaphragm combine to deliver sensational high frequency output. Sound is produced by compressing and expanding the air molecules that couple with the diaphragm's radiating surface. The AM 25 audio reproduction is immediate, highly defined, and capable of tracking complex, dynamic waveforms.
