jeah but even my setup with only a bit of height was really not stable, i thought several time "oh **** now the fall"looking at the files, thanks. you definitely need more height! Build the 2nd speaker and stack them
Nice garden.
well i have 2 of them building is done
Hi where did you get hold of the ParamEQ block in Vituix? I can't find them on my copy?
i uploaded to not eqed version but u can add them manually if u want with my screenshot. i added them afterwards
How big a cabinet would the Omnes W8 need?
Not so long ago, I, too, ventured down this path. I don't have access to many drivers in India (only Madisound ships here), and the only coaxial I could lay my hands on was the SEAS C16N001. Eventually, I decided to use a full range (Mark Audio MAOP 7) instead of a coaxial. The other alternate I considered was the Tangband W4-1879.

A rudimentary drawing of my concept is here. The final height of the drivers would be decided on by measuring my ear height.

Since my cabinet is small, I could not find any 8" woofers that would
(a) have a depth that would permit 2 of them to fit back-back in 15cm
(b) give a response (without DSP) that is reasonably flat
I did consider the SB17CAC35-8, but Erin's review lead me to believe that the driver is not suited for bass duty.

Hence I chose the SEAS L16-RN/SL (assuming that Sigfried Linkwitz wouldn't have designed a bad woofer for his LXMini).

Now I am waiting for the drivers and will start once the drivers arrive. I have included a Fountek NeoCD 1.0 ribbon just in case the MAOP7 does not offer adequate dispersion/extension above 10k.
Thanks. Based on published specifications, I modelled 4 x SEAS L16 and 4 x SB17 in 45L sealed and vented cabinets. This is what I got in Win ISD
I then simulated the 4x L16 in a 45L VituixCad just to ensure.
I won't get the SPLs that you will get from your 8" woofer. I wish we got the Omnes woofers in India.

I'll just fire up this old thread, to ask a few question - if hopefully someone knows:
1. Does having 2 woofers on each side, help with dispersion control?
2. Would it help to use smaller drivers - like 4 6,5" woofers instead - controlling dispersion and ease filtering?
3. Would a driver from LS50 meta be a better choice, since it can be crossed a bit deeper and then easier be integrated with the side woofers?
4. Would it be easier to copy a KEF R7 or R700 with forward firing woofers?
I already have a set of KEF drivers from a R3 - which made wonder how to make the best of it.

I think the middle high Coax is bether suited, even if u use Subwoofern on the sides like wavecore SW223BD they can play high enough. I used some steep active crossover.
maybe thread is interesting for you: https://www.diyaudio.com/community/...r-uniq-adventures.377221/page-11#post-6953636
If u want to use passive crossover, yes.
i cant backup my toughts on your first two questions becuase i dindt measure them with enough Gate to get accurate low frequency response to Tell.
Not according to kimmosto: (LINK)
The general ROT for side woofers is to cross them over no higher than 125-150 Hz. The KEF LS60 crosses over at 350 Hz, but the woofers have been moved up to surround the coax. YMMV
It can if the woofers are used to create an interference pattern with the drivers on the front. The front and side drivers then both need to have overlapping frequency ranges where the directivity is wanted. Blade style speakers don't do that.
An MTM of two woofers and coax on the front with a woofer or two on either side could do that, or a coax with a woofer or two below and woofers on the side.
Having 2 drivers on each side means that the fullrange/coax driver can be be between the centers of the 4 drivers. Creating a cylindrical waveform similar to a D'appolito configuration.
I used 4 16cm SEAS woofers the same ones Sigfried Linkwwitz used in one of his designs. I think the nomenclature is L16SL (H1480). Since I did not have access to a Meta driver I used a Mark Audio MAOP 7 for the midrange onwards.
The sketch below is an older version. I decided to replace the port with 3 x SB15 5"x8" passive radiators on the rear of the speaker.
I should have added, that I do use an all active system with 10 channel DSP. So I'm using a KEF SP1753A with two SB23NRX and 4 subwoofers, at the moment.
My thought was to make it look nicer and also gain sound quality. So that included looking into both active and passive cardioid and different woofers.
Dayton Signature 8" looked nice, and their 6,5" are exactly half the price, therefore an easy solution, when looking into copying your built, with both respect to me using 4 subwoofers and still doing the dispersion control of the closely spaced woofers.

Since using subwoofers, I also looked into the KEF R900, with two 8"

That's what I thought Alex (thread starter) was trying to accomplish too. My KEF coax wont handle below around 400Hz either.... so that'l be the limit aswell.
This is going to require some simulations, I recon
Haven't learned that VCAD thing yet. Anyone who has a sim I can download, so I can actually see what the program does? I have no idea how to begin. All I managed to do, was to import a driver and simulate a close box.Nice build
Yes, exactly. I want an actual benefit from the design - or else I simply think it's more successful for me to just copy a more "easy" design like the typical WCW or WWCWW in the more boxy KEF designs.https://www.diyaudio.com/community/...eaker-insipired-by-d-d-8c.369939/post-6772771This is going to require some simulations, I recon
There is an example there. You may want read all that thread.
You can also look here for a coax Blade style simulation, the wavefront is not cylindrical
