Turbosound Milan M15B Active Subwoofer

Turbosound Milan M15B — 2,200 W Band-Pass Active Subwoofer

The Turbosound Milan M15B is a powered portable band-pass 15" subwoofer built for maximum bass extension in portable PA and permanent install setups. A 2,200-Watt Class-D amplifier drives a high-excursion 15" LF driver inside a solid birch plywood enclosure, producing tight, articulate bass that pairs with MILAN Series tops.

Klark Teknik DSP and Class-D Efficiency

Klark Teknik Class-D amplification delivers 2,200 W with the efficiency of a Switch Mode Power Supply and onboard DSP. Dynamic equalisation and limiting guard against over-excursion, overheating, and clipping. A switchable Boost filter at 100 Hz and Speech/Music selector tune the response.

Driver and Envelope

The high-excursion 15" LF driver is custom-engineered for the band-pass enclosure, increasing the acoustic load for maximum bass output. Steep cut-off slopes ensure a clean transition under MILAN Series tops, while internal ribbing and birch plywood walls eliminate resonance.

• LF Driver: 15" high-excursion — long-throw cone
• Enclosure: band-pass birch plywood — ribbed internally
• Frequency Range: 35 - 150 Hz (-10 dB) — extends below typical tops

Amplification and Onboard Processing

The Class-D amp module produces 2,200 W with energy efficiency for long-running events. Klark Teknik DSP handles crossover, dynamic EQ, and limiting, while rear-panel controls include Level, polarity switch, Boost filter, and Speech/Music selector.

• Amplifier Power: 2,200 W Class-D — high output, low thermal load
• Peak SPL: 134 dB — headroom for medium venues
• Microphone Input: Yes (combo XLR/jack) — accepts low-Z mics and instruments

Connectivity, Mobility, and Physical Build

Left and right inputs use balanced combination ¼" jack/XLR connectors with a shared Level control, and XLR Thru outputs pass signal to powered tops. The cabinet ships with four 75 mm plated steel castors, a 36 mm pole-mount socket, and a non-locking IEC mains inlet.

• Dimensions (H × W × D): 495 × 530 × 480 mm — compact for truck packs
• Weight: 37 kg — single-person load with castors
• Pole-Mount Socket: 36 mm — fits MILAN Series tops
