    I suspect the quite small cabinet size of the M2 monitor is due to aesthetic and practical reasons. Quite sure both the 2216 and definately Al1501 would be happier in a much larger cabinet.

    Looking forward to play with some of your parts this summer Ari!

    I did not have time to measure the 2540SL-Be of the M2 waveguide yet, but today I did some measurements comparing the original passive network (albeit with different resistors and caps brands) and a simple 30uF Solen cap, in an effort to get back those 9dB of passive attenuation and be able to use an amplifier with roughly 1/10 of the power...
    I can share the preliminary correction adjustments if anyone is interested.

    By the way, does any of you leave near Reykjavik?

    I am also looking forward to meet you and make some speaker testing, there is also good to find someone in similar hobby like me in Iceland
    we will see how big enclosure 1501Al-1 need to get the best performance out of them, you can be sure at I am very excited to try them and also to see how good 476Mg will work on the M2 waveguide

    I like to know if 4313b have run his 476Mg on M2 waveguide, perhaps he have made it?

    Rob and friends,

    Kitchen is still not painted but I had some time and found my speaker cabinets seem to be tuned to around 25hz. Kitchen cabinets were found to be tuned much higher . I will be performing the method Rob has suggested soon.

    Thanks.

    It will work just fine

    Come on guys, where are all the DIY M2 projects?!
    I want to see pictures. I want to see measurements. I want to read listening reviews!
    Surely, there must be many finished projects by now! I have only seen 2-3 finished projects, I think.

    All my parts are still in boxes.

    Barry.
    If we knew what the hell we were doing, we wouldn't call it research would we.

    Just started the learning curve of this last night. Took the mic and Focusrite Scarlette 2i4 out of the box and verified they work when hooked up to the PC. I've never used REW or any other measurement tool before so it will be some time. Before I start this though I still need to find what frequency my cabinet's are currently tuned too for Rob (sebackman).

    After listening to the single 2216nd's your 2.5 version is going to be awesome.

    In another thread Barry suggested that he went through other JBL pro dealers other than speaker exchange to receive his D2's.

    Thanks,
    Scott
