Hello friends of sound transducers,
My milling machine is hungry, and so are my ears, so I would like to build some loudspeakers for my living room. I have already filled out the following questionnaire:
-How much money can be spent (per piece/total - with/without cabinet)
approx. 300€ without cabinet
-How big is the room?
20 square meters
-How can the speakers be set up? (a small sketch with location, furniture and listening position is very helpful)
Approximately square room, stereo system / TV set against one wall, sofa opposite against the other wall. Speakers to the left/right of the stereo system. From the sofa, the windows are on the left wall, the entrance door to the living room is on the right wall.
-Do you want floorstanding speakers, compact speakers, wall speakers or something else?
I had imagined something like the LS from the 60/70s, in terms of appearance. For example, L100 or Beovox 2400 and similar.
-How big can the speakers be?
(HxWxD approx. 600x350x400)
-Is a subwoofer available? (if yes, please describe in detail)
No
-Which amplifier will be used?
Onkyo A8820
-What do you want to listen to through the speakers?
Rock, metal, hip-hop, movies
-How loud should it be?
Higher room volume, there are songs that you have to feel
-How low should the speakers go (Hz)?
As low as possible
-Is great importance attached to neutrality?
Hm, I would like to feel the bass in my diaphragm, clear voice reproduction, defined highs
-Is there anything in particular that is important (full range, sub-sat combination, closed construction, number of ways, manufacturer, active speaker, horn, etc.)?
I'm not sure. I once read that a closed system would have advantages in terms of bass reproduction as I want it, but I also read that it depends more on the drivers. I was thinking of 2 ways, but I'm happy to be proven wrong. I think I would be tempted by 10 or even 12 inches.
I have measuring equipment and software for evaluation.
I hope that you can give me any suggestions.
Thank you very much in advance.
Cheers,
Frederik

Not having read your post, just a title, here are some suggestions from curt cumpbell and jim holtz.

Then there is troels gravesen site you probably know, and humble home made hifi

Add Alexander Gresler to that! Well-documented and no nonsense design (links to 'DAU' there too). I think Troels and Tony might bring you to using overpriced drivers and crossover stuff of which the value for money is questionable. And your budget is a constraint, certainly if you want to feel the bass in your diaphragm.

Something like Paul Carmody's Classix 2.5 or Tarkus 3 way would be worth looking at, although the cabinets are higher than you want, about 900mm. I second the suggestion to look at Speaker Design Works' projects. Wolf's Zingers have received excellent reviews, they're an 8" two way.
There are heaps of options out there; also. what you can build depends on whether you can get the drivers, some brands/items are nla.

Hallo Frederik
I've been thinking for a long time about what I would recommend for the "first time".
In my opinion, @Spillingvoid did everything right his “first time”.
He built two small full-range transducers into two surprisingly large boxes. (The two large boxes with the small transducers left and right in the photo in posting #9)
https://www.diyaudio.com/community/threads/first-set-of-floor-standing-speakers.412255/#post-7678560 (#9)
Do it for under 100€ for the two transducers (Sd ~ 50cm²). Build two boxes as big as feasible (50 Liter ;-) ). Do not Helmholtz! Fill the boxes with really big loads of fibrous stuff (before glue up). Place them as close as possible to / at the wall behind the TV. Use your Onkyo A8820.
Now you have 500€ left for active subwoofer(s). Place the sub very close to your sofa (behind/under).
Best regards
Bernd

If you want loud and clean, use PRO Woofer (12" or 15") and Horns on top. Tapped horn sub reaches down to 16 Hz in between mains. Mains reach down to 30 Hz. in corners with no sub. Easy build. All b&c Components. You can have my plans for free. These are 100+ db/watt @ 4 ohms.
My latest build with Twin 15's per side.
