It might actually produce better sound form 1 than 4 cheap ones would, but I understand.

I built s two way system based on a 6” woofer from the same manufacturer, and it produces awesome sound.

I definitely agree with you, I’m just dreading the final quote for the 3D print of my model, the component are likely going to cost less than 5% the total cost of the project

Ok, thank you for the breakdown, could I ask how do you know the module is built for a 4Ω impedance?
If I understand your description correctly (my technical knowledge is lacking) is this the kind of configuration you are describing?View attachment 239107
Not quite...

I’ll sketch something up when I get home. On my way into the city for a doc’s appointment. Or maybe someone else will.

Here is the diagram of the series/parallel wiring of 4 - 4Ω speakers to end up with a 4Ω load to your amplifier.

Just seeing this now, thanks, really appreciate it!

On a side note, I've found these speakers which are the size I want and they seem to have the correct Wattage and Ohm, however, they are AC speakers and also Hi-fi, will these still be ok to use?

Hi-fi is not an electronics term; it is a marketing firm. It means sound quality from them might be better.

And I’m not sure what an AC speaker is. A speaker reproduces the sound represented by a sound signal. Sound signals are AC, so I guess all speakers are AC speakers.

My opinion is that these will work.

I don't know where you have read this. I have never heard anyone refer to loudspeaker transducers as AC speakers. All speakers are AC speakers.

I believe that you might be over thinking this.
Get the sound module and try it with any small loudspeaker.
After that you can decide what to buy. These speakers are a dime a dozen (so to speak).

Ah ok, didn't know it was a marketing term! :D Thanks for letting me know

Right ok, I guess they just specified for the sake of it then, thanks for letting me know, I'll get these and test them out :)

Thanks, I guess it was just Amazon unnecessarily specifying something that was already standard! Thanks for your guidance, I agree, I'm ordering all of this today so you guys should have a break from my novice questions for a while lol

Those actually look better than the others you have linked.

But note: There are no spec listed. Did you notice all the specifications on the ones I linked? That is what I like to see when ordering speakers (Not that anyone but a professional speaker designer would understand most of them.)

Bob
Hi Bob,

yes I did notice that, like you said though a lot of the technical stuff goes way over my head. I’m hoping that the ones in the linkabove will be a good fit though, I know the 32mm size really limits my options compared to all the great looking 40mm ones that are out there, but the size of the base really wouldn’t suit anything larger than a 32

Exactly what he asked for. Four 30mm speakers but he wanted 3W but was it RMS or peak? He gets 1W RMS 2W peak. There is some a bit larger but more powerful: https://www.digikey.com/en/products...mon2BeSU1YbtCJZaACYqHWBiEArKdeyKAJ7yqXUJKKNAA
Hi Annie,
Yes those 2 look really good I must admit, I’m really not sure if the 3W was recommended for RMS or peak, If I was to take a guess though I’d think it was suggested as a peak, but I’m happy to stand corrected. If these seem better I can order these instead
