    Very nice work, amazing to see someone taking a power saw to the M2 waveguide...but I can see why as its oddly shaped on the edges.

    Can't wait to read the results and your thoughts!!!

    Time to set measures for cabinets

    Hi,

    Here is where the chainsaw massacre ended up. Albeit I used a circle saw
    .


    First picture shows the difference in width between standard and my "Mk II's" .


    The second shows the footprint of the baffle. -Looks pretty compact to me. No space for a port on the front so thay will have to go on the rear side. Or potentially keep them sealed and let the DSP do the rest. I've got plenty of power behind so for domestic use that may be an option. Anyone here used 1400PRO sealed? I’m using subs so I don’t need much below 50-60Hz.


    The third picture is the L + C + R wave guides ready for paint. The intention is that they will be gray as the horn in the 4365/4367 or potentially a little lighter. I will mount the 045-ti-1 horns in the WG’s prior to paint so that is next. I also need to take out some material on the rear of the WG for the 045 driver to fit. That should be a straight forward router job.

    Not really entirely happy that this will be a 4-way system but I guess that is the sacrifice to be made on the domestic alter to keep the peace. Floor standing speakers are banned in the living room. –Just have to push the DSP harder .


    Kind regards

    Compact Monitor real life measurements

    Dear all,

    Attached are some in room measurements (no smoothing) from the Compact Monitors. Crown CTS amps and BSS DSP as always.

    M2 waveguide with 2451SL/475Nd 20ms XO 544Hz LR24 100cm out with crude light eq (12db HS). Not too shabby

    Woofer (LE1400H) 143 cm out, 150ms, no eq. The room is pretty forgiving it appears.

    XO will be around 800Hz but I need to figure out the slopes as these do not have the M2 capacitor network, only a 8,4db attenuator. The originals have 36LR and 6LR which would be 36LR and 12LR in my setup without the cap's. That feels a wee bit aggressive at 800Hz for the driver...

    More info to follow.

    Kind regards

    Can I ask, what is the exact width of the WG after cutting?

    That should be a good combination with a D2 driver or a 2450SL/2451SL driver.

    Huge upgrade compared to cone mid and a dome. That would bring you very close to M2 / K2 territory.

    DSP is a must.

    Go for it!!

    I was going to post a link to this thread to you but hey , you beat me to it.

    Rob and Pos and Baldrick and Odd have trod the path for you. The only issue I would see here is if you went with the M2 waveguide you need to remember that the front edge is curved and it is bigger than the footprint of the standard grille.
    A clever fellow like yourself should be able to develop something that would ' fit '
    Glad to see you doing your homework.

    Best regards Mac
