You can use that for a subwoofer (because the ear is quite insensitive to distortion in the bass) but you can't on a mid-woofer because the unlinear Bl(x) and unlinear suspension (-> progression) causes IMD, so it's out of the question to use it in the midrange or with that excursion. Klippel got a good explaination on that on their page.
That's not very deep, so for music with deep bass a low cut/subsonic at 60Hz should be used to prevent too high excursion below the fb (where cone runs free) to reduce distortion and prevent the driver from mechanical damage.
That looks very good and that's solid advice. If in doubt (or no measurement possible), it's always better to draw the xo a bit apart and create a dip instead of having a (quickly noticeable and usually annoying) peak.
I sometimes take mid drivers beyond Xmax without issue. Because distortion is never zero, it isn't always a problem either.
Thank you everybody for hard work and answering my questions i appreciate it. also, if i build @shadowplay62 your recommended setup it will be usable? i mean my CD + 10FE200 - Mid-Woofer and this crossover everything will work together? ( i mean 4 ohm impedance at 200Hz) ?
No, that's with the Dayton woofer. The 4 Ohm is completely uncritical.
Ignoring the facts doesn't change them. And it's not the question if it's okay for you, it's the question of it's okay for @buadze007. And from what I've read in post #26, I highly doubt he will be satisfied by that. I don't believe the DA woofer will but the chances are a lot higher there.
He probably forgot to attach it or to zip/rar the file and the forum didn't accept the files.
as i posted this post i have said First time building crossover ( also first time i am building speakers) i saw OMA speaker on youtube and fall in love with design, i rushed to buy Compression driver and now i am stuck with design and compression driver and small budget 🙂 any advice and suggestion regarding midrange or subwoofer driver and crossover build for me will be a gift so whatever driver you think will work better for this build i will try to buy @ICG
Thank you again your community is very helpful
Sorry, I forgot to attach the zip file. Here it is.
I do not know if I can simulate that baffle in Diffraction tool, especially with 38 °C outside.
You are right though. It's a matter of compromise. So let's see if the compromise is on a different spot. If we'd use a 12", then the compromise is definitely the high xo frequency, respective the dispersion below 2k. So, what would we get instead?
The driver I had in mind is the the box speaker 12-280/8 A. Cheap, good Xmax, goes deep.
Again, the downside is the dispersion and it needs a large enclosure. With the planned large, wide baffle, the enclosure size can be quite good concealed. I'd say, that looks like it could be a fit for 'satisfying bass' but I have to say, I personally would definitely not like the dispersion with the high xo frequency the CD needs. But then again, it's not for me, maybe that's a compromise that's acceptable for him.
HiFi Selbstbau (German) got the driver tested thoroughly.
I have Denon AVR-2113 Av receiver to power this speaker which is 125W x 7 channels can it handle 280 W + 50W 8 Ohm Speakers?
Ah, you know your neighbours, it will take them a while to get through 3m thick concrete! 😀 😉
Well, the idea is, if you like the Thomann driver, you could at some time in the future replace the CDs with some which can take a lower crossover frequency. The "the box speaker 12-280/8 A" are from Elder Audio, they build most of the Thomann cone drivers (not sure about the tweeters). Check at first if the speaker enclosure won't get too big.
My mistake, the previous screenshot of VCad didn't show the crossover tab.
Faital Woofer (I attached the frd/zma files if you wanna modify the project).
Dayton woofer
You can... 18 point should do it. Here's a crude mockup (not to scale or any accuracy).
However, I think that baffle has more of an aesthetic effect than likely a significant one on baffle diffraction
