The new ATM Carbon was explicitly voiced for the new FEQ Carbon with its breakthrough ULF frequency combinations. Still, it is also a significant improvement over RED and GREEN ATMs when used with Atmosphere Acoustic Field Generators. When you place ATM Carbon atop FEQ Carbon, you create a more natural holographic scale with a lower perceived noise floor for effortless sound where vocals and instruments take on lifelike timbre. In addition, frequency extension improves from bottom to top, where high frequencies seem to decay into a much larger space, and bass notes are better controlled and more impactful. Think of ATM Carbon as a turbo charger for the new FEQ Carbon. Available with a no-risk 30-day money-back guarantee so you can confirm performance before making a final decision.
