Tweeter Monacor DT-140 — dome high-frequency driver DT-140

The Monacor DT-140 is a dome-type high-frequency tweeter designed for integration into multiway loudspeaker systems, hi-fi setups, PA systems, and custom speaker projects. The compact dome geometry and dedicated HF design focus on delivering clear reproduction of upper-range frequencies when paired with appropriate midrange and low-frequency drivers. The DT-140 is suitable for replacement use in existing enclosures as well as for new builds where space and accurate treble response are required.

Advantages

The DT-140 offers a compact dome form factor that simplifies installation in a wide range of cabinet sizes and front baffles. Its design emphasizes clear treble articulation and consistent dispersion, helping to integrate smoothly with crossover networks and other drivers. The tweeter's moderate sensitivity and controlled output make it appropriate for both domestic hi-fi and professional PA applications where reliable high-frequency performance is needed.

Подходит для

• Двух- и трёхполосные напольные и настенные акустические системы
• Домашние hi‑fi колонки и стереосистемы
• Портативные и стационарные системы звукоусиления (PA)
• Ремонт и замена высокочастотных головок в старых или кастомных кабинетах

Key specifications

• Driver type: dome high-frequency tweeter
• Application: dedicated HF reproduction in multiway speaker systems
• Mounting: compact flange suitable for limited baffle space
• Acoustic focus: clear upper-range frequency reproduction and controlled dispersion
• Compatibility: intended to pair with midrange and woofer drivers via passive or active crossover networks

How to use

Install the DT-140 in the front baffle of the cabinet with appropriate secure mounting and acoustic sealing to avoid air leaks. Design or select a crossover with an appropriate high-pass slope and crossover frequency to protect the tweeter from excessive low-frequency energy and to achieve a balanced on-axis frequency response with the midrange driver. Ensure correct polarity and wiring when integrating with other drivers. For replacement installations, verify the front baffle cutout and depth to confirm fit before final mounting.

Usage recommendations

Use a high-pass filter or crossover section to limit low-frequency content; apply attenuation pads or crossover adjustments if the tweeter appears too forward compared with the midrange. For optimal performance, allow a break-in period at moderate listening levels and measure or listen critically to refine crossover settings and on-axis alignment.
