Description
Double speaker SPL subwoofer
The SS 12 D2 subwoofer with its 12" cone is ready to convince enthusiasts with its power. The specially manufactured upper suspension combined with the double-layered lower suspension keep the performance consistent across the board, whether it's normal listening to music or participating in a sound pressure competition.
Heat distribution is of the utmost importance in elements like this that reach high sound pressure, and thanks to the precise design, heat distribution and fading away from the element are at a first-class level. The sturdy double voice coil has a whopping 75 mm in diameter and is equipped with air vents, thanks to which the subwoofer can withstand up to 2000 W of instantaneous power. The structure of the body is designed with heat distribution in mind and it is also mechanically extremely durable. The non-pressing paper cone with cotton fibers achieves an ideal compromise between stiffness and lightness. These two factors are of unequal importance when aiming for high sensitivity. The lower suspension and conductor cables are oversized in order to withstand the cone's exceptionally large range of motion without distressing or reducing the quality of playback. A massive ferrite magnet keeps the whole beauty under extreme control, right up to the extremes of performance. Push-in terminals make connection easy and accept up to 12 AWG speaker wire.
Characteristics
1. 74 mm double voice coil (2 x 2 Ohms) with support structure and four layers is equipped with air vents and momentarily withstands 2000 W power
2. Double layer lower suspension with progressive profile keeps performance smooth.
3. Multi-layer foam rubber upper suspension allows for large movement deviation and high sound pressure.
4. Oversized conductor cables and lower suspension are designed to withstand the demanding levels set by large movement deviation.
5. A convincing oversized ferrite magnet keeps the cone movement linear.
6. Nickel-plated weight connectors that accept 12 AWG speaker wire make installation easy and secure.
7. Non-press paper cone with cotton fibers produces high sensitivity.
