Product Description
Line array audio equipment system
S28 is a dual 18 inch inverted phase subwoofer which can provide 23-250Hz frequency range. It is designed for large line array system or other full frequency speakers, and can expand the low-frequency response of the sound reinforcement system.
S28 subwoofer uses a new design of high power double magnet bass unit, the unit with a good ventilation magnetic structure, effectively reduce the unit work in the high power state temperature, reducing the speaker power compression phenomenon. The exponential phase inverted tube body design, without airflow noise which is different from the ordinary subwoofer, greatly increasing the output of ultra low frequency energy, and reduce the frequency of nonlinear distortion; 18 inch low frequency unit uses rigid cone paper cone and pure copper wire winding sound coil, so that the sound intensity and thickness of the sound box can be shared.
There are 2 ergonomic iron handles on both sides of the S28 box, with two hanging points on both sides, so the utility model has a variety of installation; the bottom of the box is equipped with two rectangular nylon rubber feet, there are 2 rectangular rubber foot grooves at the top to facilitate the use of subwoofer stacking.
The surface of the box body is wearable black water point paint, the whole box uses 25mm birch plywood, the black perforated iron net is applied externally to the sound black gauze net, which can prevent dust and waterproof the speaker unit.S28 uses with DSP8 processor can achieve the continuous sound pressure level of output of the 136dB, according to the use requirement can choose dolly or flycase.
Applications:
Touring performance
Stadium
Theatre
Feature:
1200W (AES) LF driver
Thick & elastic lows
With 28Hz~180Hz frequency response
Mounted wear-resisting Nylon bar
With efficient hanging function
