Agree with tudscamp, Lots of good discussion here! I returned the L2m with the most prominent rattle and just received it back through the repair agent without the problem being fixed. Unfortunately I described the fault as a sound similar to a horn diaphragm breaking up at low mid frequencies- the service agent didn't find this issue and instead located a volume pot sweeper crackle... hence the problem was imediately back when I plugged her back in at home. Very appreciative of the consumer and manufacturer representation through this community. Feeling the frustration of being without the gear for about 2 weeks only to hear the same scraping sound again I was tempted to get on the phone tomorrow morning and rattle a few ear drums :) Having read the info from ArneLine6 i will now take a chill pill and calmly explain that I have a unit or two that needs a "manufacturer service letter?" applied once an appropriate product improvement is identified. ArneLine6, how far away do you believe the resolution is for us down in Oz? I won't return the units until a fix is ready else the speakers will sit in a workshop gathering dust and competitor badge marks :) Also, do you have an interal reference number for this issue so that I can quote it when I return for repair? I'm assuming your agents will get correspondence on the issue shortly if not already in their inbox? Look forward to your recommendation. Mav

Thanks for the update Jonesysam, how long does this issue take to present in usage hours? I tested my line up one by one under a test tone and found one L2m to have a crunchy horn (like it is blown diaphragm) at about 150-200Hz. Not all the time but definitely some of the time especially when it is warm (which would make sense with a resonant circuit). Guess I'll take it back to the store for a replacement and open a case through support. Plus I'll give my remaining L2m a second pass to ensure the same issue is not developing. While I was inspecting the units for loose hardware I noticed the 'm' speakers have the maker name screwed to a plastic insert which is then used to plug the mixer cavity in the box. This plate is used to hold down a section of the grill (along with the plastic/rubber end caps and socket head screws). I can imagine these parts being problematic to locate a buzz if the screw glue ever separates or cracks. I'm used to bass guitar cabinets which are mostly built to resist unwanted rattles on grills, handles, covers etc... so this inspection was a little disapointing (apart from the metres of foam tape used!)

Hi tudscamp, I have a system including the L2m, L3m, and L3s and similarly I have used the L2 on their own and am disappointed to have a rattling issue also. I have found that with low mids there is what sounds like a horn rattle (maybe a crossover problem or a loose bit of hardware). Is this the same sound you have? Before opening the thing up I thought I'd check the forum to see if anyone else is experiencing the same problem. My circumstance is that I notice it on electronic drums (floor tom) with the following points: - no room sympathetic rumbling - no distortion on the output of the drums (verified by headphone monitoring and signal measurement) - no trim clipping (verified by the above) - no M20d output clipping (verified by the above) - no power amp clipping (this will happen at about 80dB) If you do have the same sound as I describe and have luck with a resolution, please ensure to post back - I'll do the same. Any other suggestions welcome from my end. Thanks Mav
