System Configuration (Pair Only)

The TYPE 40 System is a digital, modular monitoring system built around the full-range TYPE 40 Main, an active three-way reference monitor.

Developed for studios that need a compact solution that can provide more output, low-frequency reach, and listening distance than near field monitors without the size and complexity of a traditional large-format main system.

By combining the TYPE 40 Main monitor with up to three XTD modules, studios can install the capacity they need today and expand later, as needed, while benefiting from a range of features including cardioid bass control, closed or ported, and time-aligned monitoring.

Features

  • Modular active reference monitoring system
  • High-definition Air Motion Transformer driver
  • Dedicated Class D amplification
  • 10¾-inch high-excursion woofers
  • Integrated DSP with HEDD Lineariser
  • CTRL software for advanced system management
  • Each Main monitor can add up to 3 XTD module per channel
  • Four XTD operating modes: Frontfire Ported, Frontfire Closed, Cardioid Ported, and Cardioid Closed
  • Closed or Ported functionality
  • Hi and Low shelving filters, desk filter
  • Internal processing at 96 kHz
  • Balanced analog XLR and AES/EBU digital inputs with signal-through connections on every unit
  • Side M10 mounting points
  • Assembled in Berlin with premium components
  • Each unit is tested before shipping
  • Ongoing feature support via the HEDD CTRL tool

Key features

  • TYPE 40 System configuration demo

    Scalable from Main to System

    Every configuration retains the TYPE 40 Main monitor as the complete, full-range reference at its core. Adding XTD modules increases low-frequency capability, output, and directional control without changing the fundamental monitoring character. The modules expand vertically around the Main, preserving a modest footprint as the system grows.

    More output with each XTD

    Each TYPE 40 XTD combines a 10¾-inch high-excursion woofer with a dedicated 700 W Class D amplifier. With one, two, or three front-fire Ported XTD modules per channel, maximum SPL at 50 Hz increases by 6 dB, 12 dB, or 15 dB respectively compared with the Main alone. Output can therefore be matched to the room, listening distance, and production needs.
  • TYPE 40 System in Cardioid setup with one Main monitor and three XTD modules.

    Cardioid bass control

    The TYPE 40 System offers cardioid configuration to reduce low-frequency energy behind the system. Rearward radiation can be reduced by up to approximately 10 dB. A single Cardioid Closed XTD provides directional control from approximately 20 to 200 Hz, while larger mixed configurations combine front-fire output with Cardioid control.
  • TYPE 40 XTD modules on a white backgrounds showing closed and ported modes.

    Closed or Ported

    Every XTD can operate in Closed or Ported mode. Ported increases efficiency and maximum low-frequency output for greater headroom and impact. Closed prioritises control, definition, and resolution, while providing Cardioid operation over the widest frequency range. Switching between modes is done with an aluminium sealing panel and rear-panel or software controls.

    Time-Aligned Monitoring

    Onboard DSP for the TYPE 40 System means every Main monitor and XTD module is time-aligned with three available modes: 'zero phase' corrects amplitude, phase response, and time-aligns the drivers for precise transient reproduction and stereo imaging; 'flat' corrects frequency response without phase linearisation; and 'off' provides the lowest possible latency for tracking and real-time performance.

    Full CTRL

    HEDD CTRL lets you manage all parts of a TYPE 40 System from the listening position and within one interface. It can be used to apply various settings automatically while also offering tools to adjust the system based on the room. Save presets for different workflows, formats, and listening positions with a simple click.
Adam Kagan
The TYPE 40 occupy a unique place among main monitors. They’re compact enough to work at midfield distances in a private mix room, powerful and full-range enough to serve as a true main, and expandable with the XTD system for much larger stereo or immersive installations.
