    So as the title says I’d like to build something similar to the ambeo soundbar as all of the other atmos ones from LG, SONY, SAMSUNG etc haven’t got the power I’m looking for not to mention costing crazy amounts and lack having enough flexibility with propitiatory subs or other quirks .. if the ambeo was a lot cheaper I wouldn’t be doing this.

    I’ve been doing some research and have contacted a few people about it online to see what they’re thoughts are.. I don’t think there’s any 13 way D.I.Y dsp’s that could do it (as far as I’m aware) so just using an atmos AV amp seems the best route for setup. I’m not trying to completely copy anything it’s just a guide based of the only product I’ve seen that’s like that so I will be using it as my blueprint.

    any thoughts, ideas and input are appreciated I have already heard a few positive things about plans from people but I don’t want to say anything more as that’s not my place.. I’ll most likely get help with the carpentry as my skills in that dept are that of a five year old. but the wiring and other stuff will be fun!

    Well, the thing about “us” DIY’ers is that if we are given a concept that someone else has implemented, we will do our darndest to come up with a way to do something like it. After all isn’t imitation the sincerest form of flattery? 🙂 

    Given that you have shown us what we are to look at (don’t worry about the links yet, once you hit a certain amount of posts, they’ll become available to you and you can update them then), all it takes is some analyzation to come up with a plan. It seems you are grasping the concept rather quick, so I would think you’d be able to sketch something out and share with us for collaboration.

    Keep the thoughts coming. I look forward to them.

    Thanks Cesar! I was going to wait before starting this post (while I finish up research) but I thought what the hell it’s best just to get the ball rolling! I’m going to add as much information tonight as possible, then start trying to come up with plans. The ambeo isn’t perfect for sure so I’d still be looking to use my REL sub with it as I don’t think it would be possible to get full spectrum sound without building some insane enclosure or having it huge.

    I guess the concept is minimalist and small yet powerful. I could very easily build something massive like some home cinema type of setups that people have in a separate room but I don’t have the luxury of space so a soundbar sized speaker would be best. I know there’s plenty of D.I.Y soundbar builds on YT but I would like something a bit more crazy and I haven’t seen any build out there that’s like the concept of the ambeo so it’s all I have to base it off.

    CURRENTLY EDITING. no need to comment yet! 🙂 It will likely take a few days!!!!!

     

     

    PROJECT ANDMEBRUH’ (fake ambeo soundbar)

     

    Speakers———–

    13 in total

    5x 1″ aluminium dome tweeters (do domes give best projection over distance?)

    6x 4″ long throw woofers – cellulose sandwich cone

    2x 3.5″ full range drivers (top firing) (angled 20 degrees forward? – like typical atmos speakers)

     

    Size and build—————

    it’s 127cm/ 50″ long, 14cm/ 5.5″ high and 17cm/ 6.9″ depth

    made of 3 main speaker chambers on the front (L,C,R) each chamber is isolated and a pair of L+R up firing drivers on each top end also individually isolated. (image below for reference only)

    Center channel/chamber in MTM config 2x 4″ long throw woofers with 1x 1″ dome tweeter

    L&R channels/chambers in MMTT config (if from the center?) 2x long throw woofers with 2x 1″ dome tweeters  (with the second angled tweeter on each far end/side respectively once again maybe angled 20 degrees??, second far end tweeter doesn’t seem to be separately isolated from each respective main L&R chamber)

    Up firing channel drivers on top L&R are isolated from all other chambers individually and they are the 2x 3.5″ full range drivers

     

    speakers to use – no idea yet (input appreciated here although it’s not easy getting all of the dayton audio ones in the U.K some are way overpriced depending) see above for type and size.

     

    crossovers – guess I’m going to have to make some myself by the looks of it.. which is daunting but I’ve started watching a few videos to gain more knowledge.  

     

    wire to use – no idea yet

     

    speaker connector posts – no idea yet

     

    custom grill – likely!

     

     

    Weight————–

    18.5KG – irrelevant but it should be under that weight

     

    AMP/POWER—————

     

    (ambeo) 250W (Sinus), 500W (Peak) Standby Power Consumption: ECO Standby ON = 1.9W, ECO Standby OFF = 5.5W – once again irrelevant but just for understanding.

    (ambeo) 500 watts divided by 13 is 38.4 watts, so I could be wrong here but that it’s likely 30-40w speakers being used? obviously the DSP, lights and other devices would want some of that juice. (input appreciated here as I’m not great with this stuff)

    I want some kind of home AV amp with atmos to run the soundbar. I haven’t chosen one yet as I’m still in the process of shifting my old 4k 5.1 onkyo amp. but in the meantime i’ll be checking some out, I do love yamaha though!

     

    setup/calibration————–

    ambeo comes included with stock mic for calibration but if using an atmos AV amp you could use that for a similar setup if it comes with a mic?

    Sounds like a good plan. Curious why you’re doing the side as a tweeter? Seems like it might serve you better to be a full range and then you can angle those at the 20° to get your side surround. Just a thought while you’re planning. 

     

    *Edit: I just saw the speaker you’re planning on emulating uses tweeters on the outside. So you can skip this thought.

    Hey Toid,

     

    You beat me to it with the edit lol. that’s the design they seem to have gone with! I can only guess here as I’m not sure and by no means an audio expert.. but maybe having two tweeters in a row, one on the end and one on the very side that give higher frequencies make a more narrow sound thus making it give a fake surround sound?

    Most 5/7.1 rears are quite small and not full range so I can kind of see the logic if that’s the case. I’m sure somebody else could answer that better than me anyway.

    Could be. Typically when tweeters are at an angle offset from the original, they are used for a presence speaker. Basically, tweeters in general will start to fall off based off its size and that angled tweeters is to fill in that high end sound in the room that might be lost otherwise. I’ve heard nothing but good things about the speaker, but some of the design parts baffle me. Supposedly it’s a 9 channel, but I can only count seven total channels unless those tweeters on the end are used as a separate channel without mid-ranges. That’s why I was originally saying go with full range drivers. 

    I’m really interested to see how this turns out. I’m actually working on my own seven channel. But I’m using all small full-range drivers and a tang band subwoofer. All built into 1 soundbar.

    @123toid

    Yes exactly I guess two tweeters in a row with one of those being offset give it a larger ‘stage’ to work with. As for the amount of channels I also count 7??? once again only guessing here but maybe some DSP trickery? at this point i’m just trying to gather as much information as possible and see how far down the rabbit hole it goes 😉

    @art84

    Definitely could be DSP. I feel like if I were to make a 5.1.4 soundbar, I would have four full range on the top of the sound bar tilted at different angles. Two of them tilted at say 20° and two of them tilted at a different angle based off of my seating arrangement. Of course this is all conjecture since I haven’t built one. On my 7 channel sound bar, I’m doing two on the outside tilted for rear surround and two tilted up for either atmos or your 6th and 7th channel, depending on your receiver. I’m definitely interested in what you come up with. It’s too bad that we don’t have access to a lot of those DSP wizardry boards, that we could just build into the sound bar.

    @123toid

    I thought that myself about having more up top but most of these atmos soundbars do only have two ceiling speakers for some reason even on the very expensive ambeo? maybe so it doesn’t muddy the sound as it could never be a wide enough spread (only coming from one location source) like an actual true AV amp with 10-24 separate speakers placed all around a room.

    For the form factor it’s stuck in I could see the problems having too much sound come from one area that’s trying to cast in every area.. less is more, or at least being easier to distinguish the location when it only comes from one location itself. I’m probably talking gibberish now sorry 😉

    @art84

    The one issue I could see with having more on top, would be that it could have deconstructive waves with the other speakers bouncing high off the ceiling.  Since they would be in fairly close proximity and going at a different angle, they would most likely create deconstructive waves that would affect both sets of speakers.  Of course, this is all a hypothesis, since I haven’t tested it.  But you would think there would be a reason it isn’t done.
