G.T Sound Woofer Unit uses modern technology,It reproduces the low frequency range of 28Hz to 1kHz without without distortion at 98dB/W of high efficiency which the industry's pioneers could not achieve.
G.T Sound Woofer Unit uses modern technology,It reproduces the low frequency range of 28Hz to 1kHz without distortion at 98dB/W of high efficiency which the industry’s pioneers could not achieve.
Not only loud and powerful sound,but also loud sound will not be loud and reproduce sound naturally.
Even when the volume is low,it plays the bass that plays lightly without thinning the sound.
There is no individual difference between left and right and you can enjoy well-balanced bass.
In particular,the W-Woofer system has four woofers so it sounds great!
Large Input(500W),It is made with consideration of aging,and we are convinced that it is a revolutionary unit that should be carved in history.
Characteristic
1.Symmetry double damper structure
- Dampers placed above and below the voice coil ⇒ Move up and down accurately without twisting in the vibration direction
- Improved durability at maximum input(500W) and realizes high linearity playback.
- It responds accurately even when a small signal is input and drives the cone paper to the tip of the edge.
- Prevents cone paper from sagging and deforming due to aging
2.Magnetic circuit
- Large Alnico DG5 magnet(2.85kg) ⇒ Demagnetization measures
The shape of the magnet is cylindrical (L:95mm x 9 cylinders) - High magnetic flux density1 / 24T(tesla)12,400G(gauss) ⇒ Large input (500W) compatible
- Adoption of short ring(made of aluminum alloy) ⇒ Heat dissipation measures / Counter-electromotive current countermeasures
- The pole material at the tip of the magnet uses pure iron(antioxidant paint) with excellent magnetic properties.
3.Resonant distributed frame
- Resonance countermeasures by using seven aluminum cast frame stays and irregular shapes and spaces.
4.Ultra high heat resistant & High rigidity resin bobbin
- Eliminating the occurrence of overcurrent by using a Ultra high heat resistant & High rigidity resin bobbin ⇒ Countermeasures resonance
- Improved linearity at large amplitude by adopting 18mm edgewise wound long voice coil.
5.Resonant dispersion type cone paper
- Gradually narrowing the gap between the reinforcing ribs of the cone paper(Mass:123.98g) from the inside to the outside edge
- Eliminates distortion at the edge by adopting a special rubber roll edge at the edge , and suppress reverse resonance,heat and moisture resitant ⇒ Aging deterioration countermeasures and suppress reverse resonance,heat and moisture resitant ⇒ Aging deterioration countermeasures
