Perlisten R18s

Introduction to the Perlisten R18s Subwoofer

The Perlisten R18s is a high-end subwoofer that benefits from the technological advancements of the brand’s flagship D series. This mono-driver subwoofer represents the culmination of research conducted by Perlisten engineers to offer an exceptional sound experience to the most demanding audiophiles.

The R18s features a brand-new 460 mm (18-inch) driver specifically designed for this model. Its composite fiberglass diaphragm ensures rigidity and lightness, while multiple aluminum shorting rings, oversized magnets, and a lightweight aluminum wire voice coil contribute to remarkable acoustic performance. The multilayer Nomex spider ensures precise control of the cone’s movements.

A Powerful and Intelligent Amplifier

At the heart of the R18s is a 1000 W RMS amplifier, capable of delivering considerable power while maintaining high sound precision. This amplifier is driven by a 32-bit ARM Cortex M4 floating-point processor, paired with a Ti DSP engine with 48-bit data paths. This combination allows for extremely fast and precise signal processing, ensuring optimal responsiveness of the subwoofer.

A Modern and Intuitive User Interface

The R18s stands out with its advanced user interface. A 2.4-inch color LCD touchscreen allows easy control of the subwoofer’s various parameters. For an even more enhanced experience, Perlisten offers a compatible iOS and Android app, providing full access to the R18s’s advanced settings.

Exceptional Acoustic Performance

The R18s boasts impressive acoustic performance. Its frequency response ranges from 16 Hz to 340 Hz (-10 dB), covering the entire spectrum of audible bass frequencies and beyond. The reference sensitivity is 95 dB for 150 mV at 1 meter, demonstrating the remarkable efficiency of this subwoofer.

Installation and Adjustment Flexibility

To adapt to all configurations, the R18s features balanced XLR and unbalanced RCA inputs, as well as corresponding unbuffered outputs. A 10-band parametric equalizer with 3 user presets allows fine-tuning of the subwoofer’s response according to the room’s acoustics.

The adjustable low-pass filter from 30 to 160 Hz with slopes of 6, 12, 18, or 24 dB/octave, along with variable phase adjustment from 0 to 270° and polarity inversion, offers total flexibility for integrating the R18s into any audio system.
