moved 4 woofers to the position i had in this mock, vertical its far bether then the mock with 2 big woofers(#15), if i give in the 2 woofer variant one on top and one below it has the same effect.
sure these drivers dont have the same directivity as 8 or 10 inch woofers but its not to bad to play around. I think we can assume that horizontal directivity doesnt care on which hight the woofer is.

Shhh, don't tell everybody
In general, in a comparable pass band, larger enclosures always will show more modes. That is easy math. Quite easy physics is that modal behavior in mid enclosures can effectively be tamed by using the proper acoustic measures (mainly damping).
To keep the thread a bit up to date...
I am waiting for my hypex amps to arrive,
i ordered a big piece of 19mm black mdf for the speakers
i want to try the hypex with my subs as woofers and the then finally decide which way I go
should be good enough to get an impression
subwoofer specs: https://shop.mivoc.com/media/pdf/58/80/bf/11803000_AW3000-Datenblatt.pdf
I use 2x2 so 4 in total in my subs
currently I can't decide between classic wcw or blade like with 4 woofers.

My blade vs WCW sims show a more ideal power response and predicted in-room for the WCW. In addition, WCW is budget friendly as it only needs 2 woofers. With 4 subs, you shouldn't need the additional 2 woofers to support the low end.
The blade response is by no means bad. It just shows a DI hump and power response dip at XO to the woofers - which might be fixable with more work on the XO and optimizing the woofer positions - which would require you to measure responses over wide range of angles in order to address.

sb17nrx2c35-4
i ve chosen them because of:
-cheap
-sb seems to have good quality
-low volume needed
simulation in my first post
1.
my first thought was to use 4x sb17nrx2c35-4 for each speaker to build somethink like a kef r11 but closed
~430€
Vituixcad(qtc=0,707, closed):
40l fb 69,9Hz
+headroom for eq
+with subwoofer should be possible to produce 110db >80Hz
-i dont user their mids at all(kind of a waste
View attachment 1045214
1.1 same drivers but woofers impuls compensated like blade but in a floorstanding speaker with big baffle roundover at the front
+really like this idea
-i dont know if this approach even works in my room/ in general
-how do i simulate this kind of approach?
I've used SB17NRXC35-8 and wouldn't recommend it. Erinsaudiocorner measured SB17CAC with Klippel and it actually has 2.8mm Xmax until it hits 10% distortion - the only difference from 17CAC being cone material. Subjectively i didn't like the sound of 17NRXC.
Since you have Mivoc, i'll assume that you live in Deutschland. If i'm right, you have much better and cheaper option than SB17NRXC

Thx, that's why I started this thread because I don't really trust specs.... they are speced with +-5,5mm that's nearly double. that's crazy
Ur Right I am from Germany.
The Redcatt seems nice, interesting this woofer is neither sorted in sub or woofer category so I didn't find it when I was searching oaudio.
"Not available", that doesn't bother me I waited month for my kefs
looks a bit like a peerless.
It reminds me of Peerless used for Kii Three, but an 8" instead of 6.5".
https://www.parts-express.com/Peerless-SBS-160F35AL01-04-6-1-2-Aluminum-Cone-Woofer-4-Ohm-264-1564
It seems it will be available after 15.05.2022.

don't show me this .....I wanted that driver so bad. quint told me they had some left not listed in the shop I wanted to buy them but then they said In the last moment its not to nice inverse aluminium one...
but the still have the 8 inch one:

You could check this one also:
https://www.oaudio.de/en/speaker-diy/omnes-audio/woofer/omnes-audio-w8-alu-silver.html
I think it was measured in K+T last year. Although Niklas Baur could be lying about Xmax

Compare parameters of it with RedCatt 8" and if they are close, let the price decide
would only work in the key blade like style because copper color(key coax) and alu don't really match. I need a qtc of 0.8 to reach below 70 Liters with 4 of them. talked with baur he recommends at least 25 Liter per wooferYou could check this one also:

otherwise they seem nice
4x8 Inch would be an insane speaker and much headroom to dsp
I made a slot loaded open baffle with 8x 6.5in drivers and the dynamics are fantastic. The sensitivity is also way up there. I am just amazed at the sound and goes up to 475Hz natural falloff.
Here they are!
Played a bit in my "highly professional work environment" software is a bit buggy but I am used to sigma studio so hey nothing new here.
Tried to get in the Limiters set 20, 5, 5 had a hard time hitting 20W on Woofer without using eq. Good seems to have more then enough power

I though I d make the my enclosure cylindric out of mdf rings, but that's a lot of work so I searched for something usable
https://www.ikea.com/de/de/p/vildapel-uebertopf-bambus-90233613/
Walls should be about 6mm thick, according to this thread :
https://www.der-akustische-untergrund.de/speakers/projects-for-beginners/vildapel/
I think I found a mid enclosure, seal it and maybe make another bottom with curve which also works as a bracing in the hole cabinet and I should be fine. its a bit smaller with approximately 2,4 Liters Volume.

Well after looking at the kef ls60 design, which looks quite similar to my mock, I am confident it will work.
So i ordered 8x Omnes w8
https://www.hifi-selbstbau.de/daten...ittelt-mainmenu-58/636-omnes-audio-mw-8-0-alu
they were measured here and according to that they need a little bit less volume then I calculated before.
One alternative trim ring will be printed with sis printer for testing by friend.
My original ordered one are still not shipped....

Well I designed the 3d model from ground up to use it while building.
Size atm, can be modified:
220x1100x379 mm
wood will be 19mm mdf black
Internal Volume without subtraction of bracing, etc ca. 70L
Would you change the position of the woofers? decreasing the space between them maybe?
Is the bracing enough?

That was my 'pro' setup for a few months!
Eventually, I put it in a metal box. with a laser-cut top.
Is the fa123 going into the speaker or an external box? The "bud industries ac-411" fits it if you go that route.
The hypex software is for sure clunky.
