Mackie srm450 not making any sound at all

Was using my mackie srm450s at a party had them playing quite loud they both overheated and the internal red thermostat light came on so they stopped working. Let them cool down and rest for a good while now one them wont make any sound at all. It has all the normal working lights which come on (blue led on front, green on back plus the flashing green led which shows its receiving signal input) however no sound at all. Im really confused as to what the problem is any help would be very greatfully recieved.

It sounds like the thermostat didn't shut the speakers down before they were damaged. There is probably a very fine wire leading to the speaker coils which is burned/broken. Fixing this broken connection my solve the problem unless the coil itself is damaged.

Another possibility is that the crossover circuitry in the speaker cabinet is damaged from overheating.

Sounds like you need a service tech to look at the bad speaker, unless you want to tackle the job.

    Antoine,



    About the only simple check you could perform is to take the speaker cabinet apart and visually check to see if any wires are burned & broken. If there are, these could be spliced to see if that's the only damage. This is very tedious work especailly if the wires are very fine.



    It wouldn't be long job for a tech, but their rates are pretty high -- my guess (and that's all it is) is a coupla hundred dollars.

What size internal fuse on mackie srm450v2 speaker


Mackie say this is not a user service part. If the fuse has blown there is probably a fault in the unit being their reasoning. I know for certain they tend to blow for no apparent reason so it is worth giving it a go. They are 5 x 20 Slow or time fuses. 7A for 120V and 4A for 230V

Hi I have a pair of Mackie SRM450s. When applying power I get a high pitch squeal whether I have speaker leads connected or not. After flicking the low cut or contour buttons on and off it then goes away....


Make sure you have ALL interconnected parts of the system powered from the SAME receptacle or power conditioning module. This MAY require you running an extension cord back from where your speakers plug in to supply power to the mixer. The ground bounce in power wiring in building can cause feedback or even destroying the sensitive input circuits of your system. As an electrical engineer I see these problems frequently. I think they should include this information with sound equipment user manuals, but they don't and people have trouble and damage their equipment. Doing this MAY also fix the problem you are having.

We use a mackie dfx 12 mixer and 2 mackie srm450 active speakers for a band situation the mics are sure sm58s we have to keep the levels of each cannel mixers quite high what are we doing wrong


Does the VU-meter (green/yellow/red strips of LEDs) on the mixer go all the way to the top when you adjust gain and slider level?
If yes, try boosting up the active speakers by adjusting the small volume button at the back of the speakers.
Also, make sure the equalizer (on the mixer) is set at 0 (the middle) for every slider (And not at -12). The 'voice cancellation' and 'break swich' should also both be unpressed.

Mackie SRM450 speaker keeps making a 'popping' sound


First thing is to verify that a ground loop from your driving equipment is not causing the problem. Easiest way is to drive it with a BATTERY operated little CD player so no ground loop could exist.

Verify that your power cord is in tight and try another cord to verify it is OK.

Beyond this, service is probably required. If unit is out of warranty, you could have a person open it up to see if anything is obvious.

A possible proble is bad connectors or worse, a cracked circuit board.

Analyzing if noise is from both the woofer and high range speaker is a first step.

Repair a Mackie SRM 450 Speaker The Speaker is making a crackling sound while playing. The sound keeps cracking up.


You probably need to replace the diaphragm. The diaphragm is located behind the back cap. Simply remove the back cap, remove the diaphragm, clean the voice coil gap with a piece of masking tape, install a new replacement diaphragm, reinstall the back cap. That it!
You can see videos on how to replace diaphragm at this link.

Mackie srm450 the tops on one speaker is not working


Hi There, This is quite a common problem with the Mackie SRM450's. You will find that you need to replace the diaphram on the top. This can be done by removing the 16 screws from the back of the Mackie (quite a long pain in the **** job) with a long handled cross head screw driver.

Once you have done this you should then remove the hex bolts from the back of the drive where the black and right terminals are. When this is done, pull off the cover and swap the diaphram out. With the new diaphram in place reverse the steps above but before you screw the back on, power it up carefully and check the sound is now working.

If the diaphram keeps going eg every 3 to 4 months then you will need to change the driver which is quite expensive to do. If you need spares and are based in the UK, contact LondonSpeakerShop.com who carry spare parts or can undertake the repair.

Hope this helps.
