Series wiring but separate enclosures?

Long time stalker, first time poster, and new to the hobby. I'm working on a pair of 3 driver desk speakers (2 x 4 ohm BMRs in series + 1 x 8 ohm subwoofer per speaker w/ a crossover at around 750 Hz). Given that they're desk speakers, I'm trying to limit the total volume of the box while maximizing the available volume for the subwoofer's enclosure. I'm in the Winisd design stage.

Correct me if I'm wrong, but wiring the BMRs in series typically means doubling the impedance, cone area, and volume of the enclosure. If I wired in series but sealed the BMRs in independent enclosures, would I still need to double the cone area and volume? Naively, it seems as if I would treat them like individual 8 ohm drivers at that point.

Thanks in advance for any feedback.

What are some methods for hiring crossover and amplifier designers?

So, my background is in product design, and I love designing speakers. I have some ideas for products that I would like to develop and sell but my experience in audio engineering is pretty lacking. There seem to be experts (on forums, YouTube... etc.) capable of designing a great sounding crossover in little time, while it would take me years of research and experience to get to that level. I did a quick search on Upwork, and I really cannot find freelancers that specialize in speaker design. I see a lot of audio engineers who do things like music mixings, and I see PCB designers. I tried searching keyworks like VituizCAD, WinISD, DATS, crossover design, amplifier design... etc.

Ideally, I was thinking that I could work on sourcing components and enclosure design, and then send the barebones to a speaker designer to design the crossover and give me a list of components required for circuit manufacturing. How can I go about working with an expert? Thank you

DIY streamer software

I have built a PiCorePlayer + LMS on a RPi 4 and DAC, all works nicely for Tidal, internet radio, local library. Now that the Logitech service account is no longer needed this setup can be operated without any dependence on Logitech servers.

Can other streamer platforms like Moode and Volumio be operated without an account or dependency on their servers?

Music Test Box

Today i Build this out of an old Musik Box and some stuff i had laying around. Its Basicly a music box but you can put wathever speaker u want on it. Either to test it or just to play musik. The white Button is Turning the speaker on the top on or off. The black one is for controlling the musik itself. The Orange Wago's on the inside are to Connect the speakers.

Please excuse my bad english.

Icepower 1200AS2 low volume

Hello, i have Icepower 1200AS2 and hooked it up to my woofer and mid, problem is that i mesure -10db volume on woofer and mid now compared to all my other amplifiers. What to do here? i use a dac magic that goes to DSP 408.

Analyzing speaker audio with raspberry pi

It's been a while since I've done anything with electronics, but I was thinking about making some kind of audio visualizer with a raspberry pi.

The only output I have on my amplifier is a speaker out (arylic b50) which is connected to my passive speakers. Are there any options here of using some kind of converter in so the raspberry pi would be able to process the signal that the speaker is getting as well, without actually causing distortion for the speakers?

Another option is to just use a microphone, but it probably wouldn't be as nice since it would be processing all audio in the room instead of just the speakers (still fun). It would still be located pretty closely to the speakers

Can this data input be used with dfplayer for example?

This circuit board comes from a pair of computer speakers, and I’m wondering if they can be utilized with something like dfplayer, Arduino or ESP32? Could any digital audio output work? This is only for fun, since there are other ways to play digital audio with Arduino and such.

Russound MCA-C5

I have several MCA-C5s and I noticed that I have had to randomly reboot the units in order to get the units to work properly. If I leave the network cable disconnected I don’t have to reboot them but I am unable to use my app unless they are connected to the network. Has anyone found a fix for this issue? Also is there anywhere that services these units because Russound said they will not.

First timer advice.

Hi Reddit, I am new to working on speakers but have been eager to learn. I needed to refoam this pair of JBL 125A, I went through most of the process to refoam as you can see here but before gluing the surround down I noticed significant resistance on the cone, I even hooked it up to my amp and get zero sound out of the speaker.

Here’s where I’m at, I believe the coil is toast in the one while the other is still good and I should be okay to glue it down and have one of the two working. I’m willing and interested in taking on the recoil & rebuild process, I found kits online that look like what I need.

Should I rebuild both speakers while I’m at it? Is there a reason I may want to try to keep the existing paper or should I rebuild with new cone & everything?

Thanks -guy who doesn’t really know what he’s doing (yet)

Noisy speaker hiss from computer monitor output and not phone output

I recently upgraded my computer monitor to a koorui monitor and my amplifier I use for my speakers to a TPA3116 however when I plug it into my computer monitor audio out I get a horrible electronic hiss as heard from the video which is horrible for the ears when the audio is at a low volume. When I plug in the amp to my phone however, that noise is not there and there is a very soft hiss which I was expecting anyway. How can I fix the horrible noise from my computer monitor?

I've acquired a Wireless Subwoofer which pairs with a Soundbar, but not the Soundbar. Is there any way I could connect this to anything else?

I have a Polk Signa S1 Wireless Subwoofer. Based on the user manual, the only purpose of this is to be used with a specific soundbar, which I don't have. Does anybody know if it's possible to either connect this to another device via bluetooth or take it apart and add some physical connections? I'm a speaker noob but I don't want to waste a perfectly good sub.

First DIY sub

https://preview.redd.it/20j1ng79ogyc1.png?width=1030&format=png&auto=webp&s=ade1954c0e5fa4f531dade054766d3810981a0e8

wassup guys. im building my first diy sub :)) i have done countless hours of research when approaching the build, and i think that for the small budget i have (<€500) i have found a pretty cool setup to work with. I am, however, still slightly skeptical, probably due to my lack of proper experience, about whether everything is going to work well together.

From my knowledge a 700W amp to power a 400RMS sub is kinda overpowering, however i was finding it hella difficult to find a proper amp in my budget range, especially those that ship to europe, and honestly with a max power handling of 800W i think i should be fine. Also, i was planning on putting the amp on the side of the box so that it doesnt block the port, idk if this might fuck with the sound thoug

I would appreciate any type of help... if its terrible just let me know. obviously im open to sharing more specs if needed to make better judgement, but most can be found online anw :))

P.S. if you have any other/better suggestions (available in europe) please let me know

This is what im working with:

sub : Dayton Audio MX10-22

amp: STPAS-800D

Are big brands a rip off?

Hello, i build a pair of floorstabd speakers with the Markaudio Alpair 10p driver and when i put it against the Dali Epicon 2, wich cost around 5000-6000$ new its no comparison. The only tradeoff is the treble. They are better with the Dali Epicons. But in terms of bass and mids, soundstage and details the Markaudio is soo much better.. So are big brands a rip off, then?

12v to +60v, 0v, and -60v

Hello, ive got a nice little amp that needs a ~500w dual rail supply ( has a -60v output, a 0v “virtual ground” output, and a +60v output)

Does anyone know of a relatively simple circuit to take my 12v and split it to a 60v, 0v, 60v output? preferably with soft startup and control feedback? have a milling machine, so can etch pcbs pretty well. I have seen a few designs that use the tl494 that look good, however im not very confident with transformers so it would be really handy if anyone could recommend a transformer with said schematic (or, i dont mind winding one).

Also, if anyone knows a 500w 240vac to +60v, 0v, -60v that would also be really useful. Have have found commercial ones such as the image above.
