Can I replacement the woofer on a swa1501 with any woofer

Hello, I can not say what the direct cause is,

perhaps some soldering points on the printed circuit bords are loosen due to thermic stress. test: give mechanical ticks on the woofer while he is playing to check this.
Hope you will have succes.

Start with the woofer speaker, and check with a multimeter.

If it is Ok, check/replace the amp module.

Usually the "low frequency driver"is the speaker that is responsible for playing the lower frequencies of the audio. Otherwise is the speaker that is in the subwoofer, or the woofer at the 2-way speakers. Do you came up with a problem with your own subwoofer or you are just asking a question?

In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, rate my solution with the "thumbs" or (even better) add a testimonial.

does your swa1501 get hot just being switched on ?
sounds like your output transistors breaking down or your dc to dc rectifier is shorting this would dumping high voltage to the speaker. I guess your speaker coil is burnt . check Q4,Q5,Q7,Q12.Q14,Q15,Q17 and Q18 these are all mosfet transistors that commonly break down..

The Mackie SWA1501 has an active electronic crossover on its main circuit board.

Shorted amp or blown speaker. Other things could also cause it. But there is a short circuit in it.

you have one of two problems.1) the woofer is blown(most likely) or 2) the crossover is fried(rare). Take the woofer out and press on the speaker cone(softly). If there is a scratchy feeling when you move it or if it doesn't move at all, you'll either need a new woofer, or get that one reconed.
good luck.

Hi There, If you can send a pic to info (delete this bit) at (delete this bit) londonspeakershop.com then I should be able to assist you with getting the replacement part. Best Grant

Hi There, you need to check the 3 fuses that clip onto the main amp board. You can access them by undoing the two screws that are on the top and the bottom of the sub. They have flat large heads and you will need a hex key to unscrew them. If it is one of the fuses that has gone it will either be discoloured as in burnt or you will see the metal inside has split. Simply replace these by pulling out the burnt out fuse and replace with a new fuse and hey presto you should be back up and running. If you need any parts for the sub or fuses then www.LondonSpeakerShop.com will be able to supply them (that is if you're in the UK). Also the offer a service of swapping them over for you if you really don't want to do it yourself. Hope this helps. Grant (from www.LondonSpeakerHire.com)
