Welcome to the Quantum Speaker Sample Pack
This pack is designed to give you a glimpse into what Quantum Speaker (QS) technology is capable of.QS is not just about capturing the sound of a speaker—it’s about capturing the non-linear behavior and dynamic response of a speaker in a real recording environment, preserving the full range of its tonal characteristics.
 
What’s Inside
This free pack contains four Quickstart profiles, each providing a pre-created blend of multiple microphones. These blends capture the raw and natural character of each speaker, with no added EQ or post-treatment. Depending on the sound being captured, each blend uses anywhere from two to several microphones.
 
The purpose of this sample pack is to give you a preview of what the full Quantum Speaker Pack offers.

Important Note
These profiles are designed to sound great straight out of the box, but they are raw, untreated captures. Each mic blend has been carefully balanced for a natural and well-rounded tone—but be aware that they may sound different from the heavily processed Impulse Responses (IRs) you might be used to.
 
Quantum Speaker aims to give you a truly authentic foundation—one that reflects the real behavior and feel of a speaker in a pro studio environment. From there, you can shape and mold the sound to suit your own tone.
