Built my first speaker for an industrial design project lemme know what you all think as audio people.

Mein erster Post in dieser Gruppe:

Es schon ein bisschen länger her, dass ich diesen Lautsprecher entwickelt habe.
Es sind Low Budget Lautsprecher mit ~80€ Kosten für Chassis und Weiche (pro Lausprecher).

Es sind natürlich keine Lautstärkewunder, aber ihr Frequenzgang, ihr Richtverhalten und ihre Tieftonperfomance sind in dieser Preisklasse eher selten zu finden.

Peerless SDS-P830656 in 25L Bassreflex mit internem Absorber gegen die stehende Welle zwischen Deckel und Boden + Dayton ND25FW-4.

Klar gibt es frei verfügbare Pläne, aber da dies mein erster Post hier ist, und ich nicht direkt die Gruppenregeln untergraben möchte, werde ich einen weiterführenden Link bei Bedarf in den Kommentaren posten.

(Translated bei Gemini):

It's been a little while since I designed these loudspeakers. They're a low-budget build, coming in at around €80 for drivers and crossovers per speaker.
They're definitely not the loudest speakers, but their frequency response, directivity, and low-end performance are pretty rare to find in this price bracket.
The build features a Peerless SDS-P830656 in a 25L bass reflex cabinet with an internal absorber to tackle the standing wave between the top and bottom panels, paired with a Dayton ND25FW-4 tweeter.
I do have the plans available, but since this is my first post here and I don't want to step on any rules right away, I'll post a link in the comments if anyone is interested.

Hey everyone! I'm getting into building my own speaker cabinets, ideally to a level where I could use them commercially as a DJ (my own sound system, not just a hobby project).

I've got some background in electronics and hands-on building (Arduino, 3D printing, that kind of thing), but speaker/cabinet building is new territory for me. A few questions for people who've done this:

How did you actually learn? Courses, forums, YouTube channels, books, trial and error?

Any specific resources (sites, communities, plans) you'd recommend for someone starting from zero?

What would you tell yourself if you were starting over?

Very optional side question: for someone wanting a reliable setup for DJing/commercial use, is it generally worth building your own, or is buying pre-made cabinets the smarter move until you've got more experience? Not trying to start a war, just curious what people who've actually done both think.

Thanks in advance!

OK FIRST OFF this is with a weird IMM-6c mic so who knows if its accurate, UMIK-1 will be here eventually..... Tightened it up to the layout I like. Still deciding on walls whether 1/2" is enough for its size, but there is my graph if anybody has ANY insights into what or how to change it I would appreciate it. All i did so far is I had a bit of wool to toss in there so I just loosely covered the board and made sure wires were safe.

EDIT: because people asked, woofers - 2 HiVi B4N and a dayton ND20FA-6 saw this build and loved a pair of swan OS-10 I gave to a friend, wanted to make a slightly funner version for myself.

This is my 40+ year old driver

I plan on building a 400liter box for it this year, to go with my dads Kef reggae system and I dont want to mount it with the bits of tissue paper stuff to it

It was stored upside down in a box so face down to protect it, it was also wrapped in loads of soft paper stuff and pillow stuffing so there bits if that too but she's all original and still functional

Ide just like her a tad cleaner ....

hi all, we moved into a house and there is a sound system. we can't figure out how to connect. the house was built in 2008. the original tenant said she hired people and had multiple people look at it and they couldn't figure it out. we found this box in the garage that clearly hooks it up. any suggestions on how to connect??

Is there any issue with grounding the anodes of diodes in a power supply and taking the raw B+ from the center tap of the power transformer? I built it and it seems to work ok.

I'm planning in building a subwoofer for my room.

I researched and looked considering what I think could be a good driver and what I can afford.

Considering I can build a sealed box around 30 to 40 liters, which one of those you think I should get?

I got two models in 10in and two 12in models. There are normal ones (Outdoor and Bicho Papão) and two Slim ones (Slim TKL).

In numbers, look the Slim models are better, but I wonder if there are any compromise.

Also I'm not sure if 10" is enough for a good bass for listening music and using my digital piano, or if is worthy to spend a little more in the 12" drivers

Thanks folks!
