Head-spinning, 3D sound.

The PRO-145 from Motion Sound is a complete rotary speaker system for classic organ and keyboard organ samples. It features 200W of bi-amped power, 70W for horn, 130W for the low rotor. The pre amp features a 12AX7 tube with adjustable bias and mode controls.

Have a great portable organ? Add a real rotary horn amplifier to complete your package and experience the incredible 3-dimensional sound distribution that only real mechanical rotors can provide!

Portable Rotary amplifiers are organ specific. The PRO-145 is the pro choice for portable organs. It features a 12AX7 multimode tube preamp with 2 - 1/4" inputs, a real rotary horn and real rotary drum.
A real rotary horn, real rotary drum, and an 800Hz crossover provide the different ramp times and sonic interplay so essential to the classic rotary sound.

The faster ramp time of the horn vs. the slower ramp time of the low rotor has defined the organ/rotary sound and provided hundreds of songs where this effect is dominant and profound. 2 examples that stand out are Booker "T"'s "Time is Tight" and Procol Harem's "Whiter Shade of Pale." The PRO-145 provides this classic sound and more!
