Audio Pro SUB+ MKII schematic

finski · 13th September 2011, 06:52 PM

Hello from Finland. The neighbor country (Sweden) of the make of this nice small Subwoofer. I need schematic diagram for the amplifier. LED is on and all the voltages are OK but no sound.

Reason for this silence was the speaker element. The voice coil was burned out. New driver element costs 100 euros here in Finland.

I asked the factory but they don't give any specs because the element was designed for them.

Does anybody have the specs or something? Even the smallest fraction helps. Like impedance and Fs(Hz).

You could do a bit of cutting on the burned driver to find the VC depth, winding length / gauge, etc.

You may want to check whether there's any DC out of the amplifier first.

What is the volume of the cab? Ported, sealed or ?? It would be easier just to run some T/S parameters through some modeling software like WinISD to find a good match for the cab.

Well, because this is Ace-Bass -system, I believe that it isn't that easy to find the perfect match. The amplifier has been designed using the parameters of the driver. But a good idea anyway, thanx!
