Question about Mackie SWA1801 Subwoofer
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!
Also had the same problem excepts the membrane on eminence was toren out but the coil was fine. Solution ,buy RCF G400 that is the sub in the original-first 1801s

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.
