Hello everybody ! 🙂
I'm fairly new to building speakers. I'm planning to build a pair of "Atmos" speakers, which will sit on the top of my floorstanders. I did read many interesting things on the internet, but I'd like to have some advices before buying all the stuff I need.
Why am I willing to build and not to buy Atmos modules ? The answer is simple. My floorstanders are a pair of Highland Audio Aingel 3205 ( Highland Audio Aingel 3205 Calvados - Enceintes colonne ). They are great for the price, but unfortunately the Aingel series does not come with Atmos modules. Worse, they have a width of only 14cm and most of the serious Atmos modules are larger. It would look a little weird to have to big boxes on the top of slim floorstanders ! I also have a tight budget that won't allow me to spend hundreds on Atmos speakers.
After doing some researches, I ended up choosing a Monacor SPM-116/8 woofer and a Peerless DX20BF00-04 tweeter (I attached their frequency response charts).
As my experience in designing passive crossover networks is very limited, I decided to stick with a 2nd order crossover and I designed it with XSim. I attached the simulation too. It seems that true Dolby Atmos speakers feature a complex crossover in an attempt to get a frequency response close to the one described here : Dolby Atmos Elevation Speakers - Closer Look at the Patent | Audioholics - but I also read that Atmos receiver already apply this correction ... so I think I do not really need to add more components.
What do you think about all this ? Whay could your advices be ? I also have difficulties interpreting the phase, I don't want to end up with a poorly optimized speaker.
Thanks

Why not just run the mid woofer as full range with no tweeter as the FR looks suitable. A lot of Atmos speakers only use a single driver.
The receiver will alter the FR to suit so you do not have to alter the top end. If you find it needs more top end, then add a tweeter.

This could be an option. If I go for a full range driver, I can spend a little more on it to get a higher quality one. But I can't help wondering if there won't be a lack of detail with such full range drivers, negatively affecting the soundstage produced.

A good full range driver will not lack detail. Have a read in their forum. Besides, Atmos is only an effects channel with minimal information compared to LCR channels.
BTW, I mostly use multi way speakers but have never been disappointed with the sonics of the full range speakers I've built when used correctly. My HT presence speakers use full range drivers.

Ok, thanks. I am hesitating between the Monacor, and the Dayton RS100-8. Is the Dayton worth its price? Do you know some other good 3,5" or 4" fullrange drivers in the price range?
Never used the Dayton. You are better off asking the guys in the Full Range forum as they are all over these drivers and their uses. There's some Atmos threads in there as well I think.
If you tell them the use, SPL, power handling and impedance required they should be able to guide you. Most AV amps do not like speakers below 6-8ohm on effects channels.
My Atmos / Presence speakers used 3" FR drivers that were too low on impedance and power handling so I had to do dual to overcome these issues. This is supposed to have combing problems but in service haven't noticed it.

Great!!
Thanks for your help. I like your Atmos speakers, they are simple and have a nice finish.
My receiver is a Denon 2500H, it should not struggle to drive them and should be adequate for a 20-25m² room.
I'm going to head to the full range section for more informations.
Thanks again 🙂

Had a quick look at the Dayton and prefer it to the Monacor. The RS100-8 has received some good comments in the FR forum. Another option is Mark Audio Pluvia Seven which I've never used but seems to have a good reputation.

Yes, the Dayton seems more suited to build a proper full range speaker.
As for the Mark Audio, it seems good too but it is unfortunately not sold here...
Thanks for your help. I'll go with the Dayton, which seems to be in my sweetspot.
