- 3mm thick stainless steel ring placed on top to increase the strenght and reduce flexibility of the aluminum basket - minor sound aberrations consequently.
- 2-layer crossed glass-fiber/carbon-fiber cone gives an higher stiffness to reduce the break up on the edge.
- The cone's lower weight improves the agility of the woofer in itself allowing to reach higher frequencies making the pairing with the T25T easier.
- The new bi-wire voice coil (lower induttance, almost ½ of its predecessor S165W) has less back electro-motive force, to less magnetically restrain the cone and make it more free to act.
- Very lightweight glass fiber voice coil support for a better heat sinking.
Normal Impedance: 4Ω
Power RMS: 90W
Voice Coil Ø: 32mm
Sensivity: 89dB
Frequency Response: 60Hz - 8.000Hz
Fs: 61Hz
- Brushed aluminum frame and grill
- Bigger spool than its predecessor S25T, less excursion of the dome, and less wire to obtain a better response between 5 and 10KHz.
- Higher grill's full/empty rate
Normal Impedance: 4Ω
Power RMS (filtered 12dB 6000hz): 100W
Power RMS (filtered 12dB 3500hz): 60W
Voice Coil Ø: 25mm
Sensivity: 90dB
Frequency Response: 2.800Hz - 20.000Hz
Fs: 970Hz
- 1,6mm phenolic laminate PCB protected by black solder resist photoresistant on copper side;
- Exclusively hand made soldering, double quality check - visual and electrical.
- Low induttance metal oxides resistors to avoid the sound “coloration”.
- Thermocemented Copper used to avoid mechanical vibrations and optimize layering with a resulting improvement of the Q factor and the transfer function. For a clearer and more full-of-information sound.
