Question about Alesis M1-Active MkII Main / Stereo Speaker

Alesis M1 Woofer stopped working

Hi, my speakers are out of warranty and both stopped working roughly a month apart. I do push them pretty hard (but not so they are distorted)!

Interestingly, when i physically push the cones back the bass kicks in for a split second... I was wondering if this could be a physical problem with the driver itself or whether something has blown on the main board so that there is not enough current to drive them properly?

Any suggestions would be much appreciated :)

    Same problem, just the woofer has stopped working. When I gently press and hold it though, it sounds like it would be fine.

    Can I fix this without a new driver?

Your problem is a damaged voice coil, you will have to replace the drivers, or the voice coil. I suggest personally replace the drivers as it's a lot cheaper then getting the voice coil repaired. The reason for this is pushing it hard, it seems like the coil came out of the magnet a lot and when it does that it gets heated up extremely hot and the chance for the coil to burn is high.

Check the condition of the surround(foam or rubber) of the driver, if it is deteriate,or crack, you have the replaced the drivers(woofer cone),I have that happened to my NHTs one time, after I replaced it, it sounded like it was new, depend on the drivers price, it might be better for you to replaced the whole speaker.For me, it was worth it, because the new drivers have rubber surrounds, instead of foam, which will last me a long time.

Hi one of my alesis m1 520 speakers has a fault . it powers up ok but theres hardly any sound coming out . you can hear it but its very low


Try reversing cables between speakers just to make sure it's not cable or source. If it is a bad soaker, you'll need to contact Alesis for a local service center near you. Check w/ Guitar Center also, they have access to service.

One of my speakers has started emitting a " fartinf like sound, it's not blown but sounds like someting vibrating against the woofer, if that makes sense?


Check to make sure all screws are tight. If they are, it's possible the surround or the spider on a woofer is letting go. Check to see that they are intact.

There clearly is a fault in the sub's amp section. It's probably the main part that does most of the work. It will need to be replaced.

I see from the manual there are several controls on the speaker that could affect the sound in the way you describe (gain, hi- and mid-boost, acoustic space). Why don't you compare the actions of each control with the working speaker as the standard and a test tone or FM noise as the source? It might help you to identify a specific internal function that has changed. After that, someone's going to have to crack it open and do surgery.

You might also try using the opposite input (TRS vs XLR) than the one you're using. It might reveal something.

Fried Woofer


The problem are worsen that before. It is wisely to replace both left and right amplifier
IC, but make ensure that the power supply feed a good amount of voltage to amplifier,
Also a strong good signal. Be sure to measure it.

Opening up speaker enclosures


take out the screws that hold the tweeter in place and lift out the tweeter. There is a cover that hides the screws on the woofer. Its the one on the front with the Alesis name on. You need a small screwdriver or small blunt tool to prise it off. One off you will see the screws for the woofer
