The D-Series represents a cutting-edge speaker line tailored for the latest digital, modeling, profiling, and IR-based amplifiers, and is also suitable for acoustic guitar amplification. However, it is not recommended for use with traditional electric guitar amplifiers.

With an extended upper range response, it captures the intricacies of digital effects and the harmonic richness of a mic'd guitar cabinet. The N12D, inheriting features from classic guitar speakers and incorporating an integrated paper surround, delivers the tactile sensation, warmth, and personality of a vintage guitar amp, as well as the high-frequency details and complex harmonics of overdrive, modulation, delay, and reverb effects, along with the clear, authentic sound of an amplified acoustic guitar. Its Neodymium magnet construction also reduces the weight to a mere 2.4 kg.
