Title: 33 volts rms of audio low efficiency driver View count: 100 Rating: 0 (0 ratings) Description: I am softening a huge woofer driver..the unit has a very massive cone and a very hard suspension..reinforced with a cloth dampened with some glue...driver is hard to move and need some softening working some hours with high power on it...the real softening is happening with 20 volts RMS...showing you full power (33 Volts RMS over 8 ohms..means 136 Watts RMS)...and you listen some deep tone of 60 hertz together the non audible 8 hertz that is entering the power amplifier..the tone you listen is because the supply is unable to filter...the 25 thousand plus 25 thousand microfarads is not enougth to drive full power (33 Volts RMS) into 8 ohms...bad supply!.... speaker is also not good...it is noiseless, or, does not produce noises while moving... the noise you listen is from the 60 hertz non perfectly filtered supply..other high frequency pitch is because air is scaping behind the midrange and tweeter drivers (I will use silicone glue)... this speaker needs a lot of power to move..it is a 500 watts driver that uses the trick to be hard to move to hold all that power...also the coil is large, the wire diameter is large and there's a hole for ventilation purpose..the coil grile is also filled with small holes for ventilation too.
