    So sorry I missed your post/questions. Life you know... Making my way back to the speaker world... like a warm blanket.
    I surmise you have already decided on how you are proceeding, but I will chime in anyways

    djg is correct, do not worry about the baffle thickness here.
    Regarding sub crossover, I'm doing 75hz.

    If you click on ck moore's name, you'll see he hasn't logged in here since April. He might visit without logging in, I'm sure 3/4" is fine, keep the same volume.

    You might need to relieve the back side of the baffle to allow better airflow.

    Sorry to perform an act of necromancy.

    I’m looking at this build as a potential solution for my home theatre, since it seems to tick all the boxes:
    • Goes low enough to allow an 80Hz (or slightly lower) crossover to a subwoofer.
    • Close to wall mounting (so the surrounds and backs don’t sit in the walkway through the home theatre area)—this shoots down any rear ported and transmission line designs.
    • All the parts are still available (this shot down the AviaTrix I was looking at—but the low back to front profile of these is probably a better idea anyway).
    I do have a a question (or two) though:

    The plans you have on your picassa show a ½″ thick baffle, but the baffle you used was some ¾″–⅞″. Does this make a difference? I have easy access to 19mm thick Tasmanian Oak, but in the width needed I can’t get it in 12mm, so a ¾″ baffle would be much easier.

    What frequency are you crossing to your subwoofer?

    Thanks,

    Mark.

    I realize this thread is ancient...Have a crossover question. Are the B3N mids and tweet hooked up in reverse polarity, with the B4N's normal polarity?

    After reading the whole post, I have learned more about this topic. Thank you so much.

    Hi, sorry to bump and old thread, but how would these compare to the Overnight Sensations MTM? I have a set with the center channel and I was thinking of scraping the center and using the B3N's from it in the mains to make these. It would cost about $50 each for the crossovers and new tweeters (I used the HiVi ones in my OS's).

    This is my current setup: http://techtalk.parts-express.com/fo...uild-os-mtm-cc

    Do you think it's worth $50 each or should I just keep the Overnight Sensations? They will be in the bedroom, 2.0 system. Maybe eventually a 2.1 using the Voxel sub.

    Thanks.

Paul helped me tweak the padding on those, since they were were a bit hot initially.

    As for changes if doing them again? I would not use hurricane nuts. Don't do it. And I would not have used such large wire on my crossovers. Live and learn

    Here is link to my full build pic library. Hanging pics, they are old, since I have a different tv. But you get the idea. TV is a 2006 48" plasma.

    thank you for coming back to this thread to answer my questions. I am not even an a noob audiophile so i am not interested in buzzwords, and could not even begin to pretend to understand what all the graphs and raw data means around here. I know I have heard speakers, IMO, that have sounded good and bad, and what I like. I also know my situation limits a lot of what I can do for LCR speakers, so I will take what i can get so to speak

    Love the way they look... very well done! Do you have a larger TV now?

    thanks again!

    Shawn

    Howdy, came to this thread after Paul Carmody said to check out other versions of his event horizons.

    Are you still using these as LCR?

    Are you happy with them?

    If you were to build another set today, would you do anything different? If so, what?

    Hope to hear from you... 98% sure I'm going to go this route. Thanks!

    Re: Sensational Events: a build

    This looks like the perfect solution for a shallow on-wall build. Any pictures of them wall mounted? Listening impressions now that you've had them for a couple year?

    Also, any chance you have any FR graphs?

    Thanks.

    [QUOTE=ckmoore;1792468]I was playing around with Visio on the XO layout...


    What's the overall impedance of each of these?

    Re: Sensational Events: a build

    Nice build! I really like the os mtm's a lot but I like a lot of bass so this would be the ticket. I wonder what Paul's larger version referred to on the first thread is going to be?

    Also, I learned this trick from Kanemack but if you use a scrap piece underneath your baffle (1/2" or 3/4") you can use a 1/8" inch drill bit (the same size as the dowel/pin for the router circle jig) drill through the center hole through both until the drill bit sticks out enough to fit into the circle jig, unscrew it from the drill leaving it in both the baffle center hole and the large scrap piece under it. Secure the baffle to the scrap piece with clamps so it can't move. Now when you make your holes you wont ever that that point when the circle moved at the last 1/8" of the cut and if you mess up the jig / center point cannot move because the drill bit is still stuck in the scrap board underneath it. you can just keep using this scrap board for all your future builds.

    It's a super easy thing to do and it's better then the pin that comes with the jig because it's got a lot more length so it protrudes into the wood and your router better.

    I know it's too late for you but hopefully someone else will read this and use it as well!
