The Ti-18SA is the active version of the popular passive Ti-18s subwoofer, equipped with the PM4000MD amplifier module by Modern Acoustics. It is a complete, standalone 2.1 system for professionals who want powerful, clean bass without the need for an external amplifier or rack.
Professional sound with an Italian signature
At the heart of the speaker is the Lavoce SAF184.01 18 woofer — one of the most reliable drivers in its category. With 750W AES / 1500W Program power handling, 99dB sensitivity, and 134dB SPL maximum sound pressure, it delivers strong, controlled bass from 38Hz, even at high volume levels.
2,000W Class D amplification with DSP
The integrated PM4000MD module powers the woofer with 1,200W RMS and also features an additional channel delivering 2,000W RMS @ 4Ω / 1,200W RMS @ 8Ω for passive satellite speakers.
With built-in DSP — including parametric EQ, noise gate, and full protection circuits — WIMA capacitors in the preamp stage, and a full-bridge switching power supply, it ensures stable, musical performance even at the limits of its power output.
