Question about Mackie SRM-450 System
Hi, I have a pair of SRM 450 V2's. The main 15? speaker has stopped working. There is no sound whatsoever coming from it. The horn seems to be working fine. I checked the fuse on the board and its not burned. Is the speaker blown? In past experience blown speakers usually sound like crap but you still hear them. Thanks!
IS there a circuit board inside that speaker? You are correct about the general loss of sound quality that usually occurs with speaker failure. Best way to check is with a meter or a scope

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.

1)Clean the heat sinks on the amp on the back of the speaker,
2) carefully remove the amp from the rear of the cabinet and look for 'crispy critters' on the circuit board. If you see 'um, either take the amp to a service center, or go to your dealer and get him to order you a new one.
3) if you're goin' thermal, either get higher powered speakers, or tune it back a bit with these. I have a set that has run years in a dance room with no problems. If you are stretching the system to cover a bigger audience, think about another pair.

When it goes off, try pressing gently on the speaker membrane (you'll probably need to remove the protective mesh to do that).
If the speaker comes on for an instant or so when you press the membrane, then the cause is a broken braid wire at the back of the speaker (it goes from the connection terminal on the speaker itself to the speaker cone where it is connected to the speaker coil wire and glued to the cone to keep it firmly in place).
If this turns out to be the case, the braid can be resoldered at the point where it is damaged / broken (you need good soldering skills to do it, also the braid needs to be cleaned well which is a bit tricky because of its structure, and solder won't stick to it well if it's not clean).
The solder point should be firm, but as small and short as possible because the braid needs to remain flexible at all times since it moves when the speaker is operating.
An alternative to braid resoldering is to replace the speaker, but there may be speaker repair shops around where you can get it fixed.
The problem may as well be something else, the above is just one of the things that you can check and possibly fix by yourself.
