MACKIE SWA1801--Sound quality is not same

Hello! About 4 years ago I bought one MACKIE SWA1801 subwoofer in Hungary and 2 years ago I also bought a same sobwoofer from Austria. The problem is: the new one can not working well. If I push up the fader on the mixer the woofer can be make a distorsion but the PEAK LED is not light. And the older subwoofer is working well parallel. I re-assembled the woofers from the wooden boxes. The older woofer was made by RCF the new was made by Eminence. I went to the speaker enginner. (He has 15 years experiance in the woofer world). He said the Eminence woofer is working Ok. The membrane and the coil is not damaged. It seems everithings are OK. I made cross test. I mean I put the Emience woofer in the onother box with the older amplifier. The result is same. The woofer is working well on a little volume but if I push the fader to get a bigger sound the woofer is distorted. I am really sad now because I can not hear my loudspeakers in same volume level. I have to reduce the volume of the right What can I do? Would be buy a RCF woofer to get a same sound quality? I hope you understand my problem. I waiting for your reply! Bye and thanks in advance!

Hi,
First, Try the "defective" woofer in the cabinet that works well to be sure the woofer is OK.
If the woofer sounds good in the other cab, look to the power amplifier board : you have to test 2 fuses and 2 transistors witch are connected to the fuses : a defective transistor let your subwoofer work fine to half power, but distortion appear if you push away...

I suggest, go out and buy a heavier duty 18 and replace it.

Both my 1801s gone over xmas..fuse at bottom of board popped when swiched on, replaced fuse but no sound now although LEDs are on?


Fuses blow because of an overload. In this case it will be a shorted semi-conductor. Most likely in the main amp section. Maybe the main amp itself. It might be attached to a heatsink.

I have damaged the cone on my swa 1801z subwoofer can I get a replacement cone and where ?


  • Yes you can. It is not the easiest of tasks but far cheaper than replacing that 18. There are a few places you can get recone kits from so I will list a few of them and let you decide the quality of kit you wish to purchase.

  • Here is a place that will recone all moving parts for you. Of course there is some shipping involved.

The thermal light comes on on my swa1801 and lose all audio what could be causing this to happen?


make sure its plugged into a large circuit over 30AMP! Turn down the gain on the back. They can't take too much punishment so turn the bass down on the eq. Get a stronger sub

How do you get to the ac fuse on the SWA1801 ?


There are 4 allen-head screws that hold the amplifier assembly in - two on top and two on bottom. Remove these and the entire thing slides out the back. There is one fuse near the power switch and two on the power supply board inside. Be sure to use the correct value.
