“The M&K Sound X15+ doesn’t seem to fear any content, no matter how high you crank the volume it just keeps getting louder” – Home Theater Forum, April 2023

If you do somehow reach a point where it can’t go any further it smoothly engages protection mechanisms and prevents itself from coming undone. The X15+ is insouciant when driven, it doesn’t care you’re doing everything in your power to bury it. Even at the extreme it remains in control, never losing the ability to reproduce clean sound. It doesn’t just excel at sheer output, it backs up that skill with precision and detail. If you have big demands the M&K Sound X15+ subwoofer is certainly able to fulfill them. Highly recommended.
