    Merry Christmas to all. Just wondering if there is any plans in the future for a DIY build for some Atmos speakers? Paying $700 for a pair of Klipsch RP-500SA reference monitors seems like a lot. Especially when you need 4 and maybe 6. Any suggestions?

    @mjcaron Merry Christmas! I am assuming you mean top firing atmos like the RP-5o0sa?  If so, the answer is not at this time.  Interestingly, there is a special filter that is designed specifically for upfiring modules.  Even more interesting, is Audioholics tested both Atmos modules with the filter and just regular bookshelf speakers and found them both to work just fine. In fact, they preferred old 2-way bookshelf speakers. Of course, they put them upfiring at about a 20 degree angle.  Obviously this is their opinion, but if you have some laying around you could try them.  If you like it, it would not be hard to create a twenty degree stand.

    so, is this filter just something that could be pulled out of a device and analyzed? it seems like this patent app has some cool diagrams to show some frequency response curves US10313793B2 – Passive and active virtual height filter systems for upward firing drivers – Google Patents

    hello @123toid,

    I so your response above related to the up firing atmos speakers, bur dedicated direct speakers? I would like to build 4 of those also after the 5 pcs of V1/V2.

    I so that coaxial drivers are behaving quite well and are compact but what is available on the market is a little pricey. 

    Any plans in the near/medium future?

    @cristidumi There’s quite a wide range of coaxial drivers out there, if you are looking for cheaper ones, sometimes car audio drivers can be used depending on box requirements etc.

    I presume you mentioned coaxials for use in/on ceiling, however there is the on-wall option where you place the speakers 30° up from the listening position, in fact this method is preferred by many, not officially supported by Atmos, however it is supported by Auro-3D, if you have a receiver/processor that supports Auro-3D, it can do upsampling even from Atmos. You can of course still use on wall for Atmos, but being that I don’t have either, and haven’t tried either, I don’t know how well the experience converts, just know the options exist. Either way, on wall or in ceiling will provide a much better experience than the “bouncy-house” speakers that go on top of ear level speakers, although I’ve heard those speakers that sit at ear level are still much better than having no height at all. Hope this helps 👍
