So these speakers broke after about 2.5 years of use. I expected them to last longer than that, so I'm pretty disappointed. Anyway I decided to take apart the active speaker with the power supply in, so here's a guide.
1. First remove all the screws around the outside on the rear of the speaker. Don't remove the screws which aren't around the edge.

| Step 1 - remove outer screws only |
2. Put your finger into the ventilation hole and pull off the back panel.

| Step 2 |
3. If you need to remove the front of the speaker, then reach inside and there are four screws to be removed, one in each corner.

ReplyDeleteI had the same issue. Pulled apart my CR4's and just soldered a bridge between the respective middle switch pins and the 'R' position pins. Works fine, just lost the ability to select between L & R but this isn't a big deal to me
ReplyDeletethat seems to be everyones problem with this product.
Delete10 k resistance is getting heated
ReplyDeleteHi there, does anybody know where the internal fuse is located within the assembly? I've been given a pair of CR4s and told the internal fuse has blown, but looking at photos, cannot find where it may be located.
ReplyDeleteThe holder fuse, a black cylinder, is between the transformer and the heatsink. In the photos above it is seen almost end on with a red wire going into its end. Between it and the heatsink is a blue wire.
DeleteAnyone know how to take apart the passive speaker? There are no screws showing and I don't want to go ripping on the bezel...
ReplyDeleteI need it too...
DeleteHi,
ReplyDeletei need it to. After 2 years, the tweeter of the passive speaker is not working. How to open it? Not have any screws... thanks
The front cover can sometimes, if you've got strong finger nails, be pulled off the box by hand. When that didn't work then I very carefully put the long sharp edge of a knife into the box/cover joint and levered the front and box apart enough to put an old credit card into the gap. Then I work the card around the whole length of the joint and added another card to make a thicker wedge and worked that around. And then I used my finger nails.
ReplyDeleteBe aware these speakers have a design that often gives them a very short lifespan. The 12 v / 20 v area of the circuit board and the components there get cooked. See the darkened patch in the image of the back of the circuit board above?
