Hertz Dieci Series DSK170.30 6.7inch 160W 2 Way System

Hertz MPS 250 S2 shallow subwoofer has been designed to achieve exceptional performance even when there is very little space available to install the subwoofer box.

MPS 250 is optimized to work in ultra-compact sealed boxesstarting from only 14 Lt (0.49 Cf). A typical example is a subwoofer enclosure under the rear bench of pickup trucks, where the space – and the height – are limited.

Mille PRO shallow subwoofer have a depth/performance ratio never achieved before thanks to the impressive cone excursion capacity which is 20% higher than a traditional design.

This exceptional target has been achieved thanks to the ingenious suspension group design featuring a dedicated support structure for spider and coil. This solution has allowed to move the magnetic group inwards, reducing the depth and at the same time maximizing cone linear excursion.

Features:

1. Ultra-shallow overall depth
2. 500W continuous power handling
3. Optimized for extremely-compact sealed enclosure 12-14L (0.4-0.5CF)
4. Air Intercooling Revolution (A.I.R.) prevents air-compression-related limitations
5. Unrivalled mechanical excursion, +20% over traditional designs
6. Six-layer copper voice coil (38mm/1.5 in.) ensures high thermal capacity
7. Non-vented rear design allows reduced enclosure depth
8. Robust screw-less mesh grille included with black screws provided
9. Die-cast aluminum frame
10. Solid horizontal 8AWG spring-loaded terminals
11. EID: Scan, Discover, Identify
