Custom Organs are designed to the specific tastes and preferences of each customer. Consulting with local Allen representatives and Allen factory experts, Quantum customers choose from a variety of stoplists, console styles, keyboard finishes, drawknob treatments, audio systems and much more to create a unique instrument that is both a musical and visual work of art.

Many Quantum organs incorporate Allen's exclusive Multi-Point Audio™ design, producing clarity, detail and realism surpassing all other digital organs. The organ's sounds are divided among a lavish number of amplifier channels and a wide array of speaker enclosures, each optimized for a specific portion of the organ's tonal spectrum, creating spatial dimension that rivals most pipe organs.
