Turbosound Milan M18B — 2,200 W Band-Pass Powered Subwoofer

The Turbosound Milan M18B is a 2,200-Watt powered portable band-pass 18" subwoofer built for maximum bass extension in portable PA and permanent install applications. A high-excursion 18" low-frequency driver pairs with Klark Teknik Class-D amplification to deliver tight, room-filling low end for live bands, mobile DJs, clubs, and houses of worship. The Turbosound Milan M18B is the right choice for sound providers who need touring-grade bass reinforcement in a single, road-ready cabinet.

Klark Teknik Class-D Power and Custom-Engineered LF Driver

A switch-mode power supply and Klark Teknik Class-D amplifier topology deliver 2,200 W of output while keeping the cabinet manageable for one-person load-in. The 18" LF driver is engineered in-house with a 4" voice coil and double suspension for improved transient response, pairing cleanly with MILAN Series full-range loudspeakers.

Amplification and Protection — Touring-Grade Headroom

Class-D efficiency eliminates heavy heat sinks while preserving the dynamic headroom needed for kick-heavy program material. Onboard Klark Teknik DSP provides dynamic equalisation and limiting, with full short-circuit, thermal, overcurrent, and DC protection on the amplifier stage.

• Max Output Power: 2,200 W — headroom for full-range tops and high-SPL rooms
• Power Consumption (1/8 max): 280 W — efficient switch-mode supply
• Amplifier Protection: Full short circuit, thermal, overcurrent, DC

Acoustic Performance — Band-Pass Efficiency and Tunable Bass

The band-pass enclosure reinforces bass musical-instrument frequencies, with steep cut-off slopes ensuring a clean handoff to MILAN Series tops. A switchable Boost filter adds +6 dB between 40 Hz and 90 Hz for system-dependent shaping, and a polarity switch keeps phase aligned with full-range loudspeakers.

• LF Driver: 18" high-excursion, 4" voice coil, double suspension
• Frequency Range: 40 Hz–100 Hz (±3 dB), 30 Hz–150 Hz (-10 dB)
• Max SPL (peak): 134 dB (half space)
