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.

The actual cone it self... There is no permanent fix for this you can try to use clear nail polish on it by removing the grill and applying polish to ripped portion of the speaker

How to open a Mackie SRM450


Sorry about the late response. These units are sealed at the factory and opening them up for the first time is a bit of work. Make sure that all the screws are out of the unit and using a large screwdriver, carefully pry up one side. It will be difficult. Apply steady pressure and the back will eventually free up.

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.

Any idea why my Mackie swa1501 bass bin has blown 2 speakers in the last 3 months? Bass Drum is the heaviest instrument going through it, but I never let it clip, I also run a fan on it which keeps it...


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..
