Hello,
I have several questions, regarding Troels design or general design for a 3 way with speakers (no compression) :
He chooses 15pr400 because it is very good in the mids and crosses at 230hz. The mids play between 230 and 2800. He chooses an 18s 8". Of course he uses simple passive crossovers so the slopes are low order slopes...
My questions would be, if we assume that max SPL is not the purpose.
Do you prefer a 6.5 or an 8 to play between 250 and 2500?
If such a 3 way is used, where would you put the lower crossover? Higher than what he does ?
If DSPs are used what kind of slopes do you prefer?
What mid would you pick ?
Regards Greg

I would have liked to know a Hypex preset for the 3wc-15 based on good measurements
for me, it s better to cut a 230-2000 and not 2800Hz ..
but why not. the 15pr400 is good if you want very light bass with 4 cu ft

Yes I agree with you, that is why I got a pair of Audax tw34 and a pair of wavecor tw30a12 to be able to cut lower with waveguide...
But to get the punch don't you cross the low higher ?

Forget the punch for now. Match up your ways and you can adjust your EQ after you have it right.
8" is less suited to crossing above 2k. You might cross it higher to a waveguide.

Well listening to some music with the kid and I changed the xo from 300 to 500hz and it has more energy and strangely the weird thing I had on the lower harmonics of the female voices seem gone...
Maybe 300hz is too low for 6md38...?

There can be different reasons why changing your crossover point helped. For example, what if each driver has a different floor cancellation frequency because they are at different heights?
So you can't simply say it's the crossover by itself, or even the driver.

Yeah you're right could be lots of things but maybe simply my 6md38 is not done for 300hz, this is were its rollof starts and I'm using it open baffle... Actually even the upper mids seem better.
All the measurements I made were not bad down to 300hz and it is not a bad listening.
I have 2 headphones,
Audiotechnica ATH-W1000X, Sennheiser hd650.
If you cross at 500hz you are more like audiotechnica, at 300hz it is more like the hd650...

I run a pair of speakers for the stereo setup in the living room with the open kitchen that are taken from the loudspeaker II idea of Troels Gravesen.
2 X 15 inch open baffle subwoofer, 10 inch kick bass low midrange, 18sound NSD1095N compression driver plus XT 1086 horn and Visaton TL16H super tweeter with a subwoofer plus 3 way active crossover with 2 miniDSPs 2 X4 HD devices.
Especially with higher SPL i have never heard something close to them.
Beside may be many many years ago the Beveridge big electrostatic towers or the big 15 Inch Tannoy coaxial speakers, all much more expensive - unreachable for people that do not want to spend a fortune for a pair of speakers.

Hello,
Thanks for describing your setup but coul you give more details ahah, sounds interesting. Speakers, crossovers, load ?
Interesting I was looking at different speakers
Faital 3WC-12
Point of crossover: 500 and 2400 Hz, LR2 filter
Faital 3WC-15
Point of crossover: 230 and 2800 Hz, 2nd order crossovers (LR2)
Tl1:
Four-way floor-stander from 18" +10" + 1" comp. driver + horn-loaded tweeter.
Finished speaker weight: 85 kgs/ea
Sensitivity: 95 dB/2.8V/1 meter
Impedances: MTT section: 4-8 Ohms, minimum 4.3 Ohms @ 600 Hz. Bass section 8 Ohm, minimum 6.5 Ohms @ 25 Hz. If run fully passive from one amplifier, minimum impedance will be 3.0 Ohms @ 120 Hz
Points of crossover: 200, 1300 and 9000 Hz....
Obl-15
Points of crossover 180 Hz (6-12dB) and 2 kHz (24 dB).

I have opened an own thread here:
MEGB1262 SW + 3 WAY THREAD
With no decent measurement equipment yet and the active XOs i am still in the process to find the best active XO settings with a lot of listening tests.

@Sebas75003 signed up to diyaudio to see if anyone responds to this question. Am super interested in hypex-powered diy kits but am not 100% sold on the Seas 3-way hypex kit.
Me too. I've just ordered the components and a pair of hypex 503 to do this so any advice or experience others have had would be interesting to read
Perhaps one Day the passive crossover for faital 15" (med +tweet) become open source, with a activ crossover for 15pr400 is a good match
the new fusion 22 speaker is nice aesthetically and the medium is very good.. I'm very curious to have dew returns
the 8m400 are said more forgiven about the two ! 2000 hz is a little high for most of the 8" : tweeter should cope the 8" beaming there, that is meaning WG use ! Without you should be more confortablle between 1000 to 1500 hz with your 8" ! (and PA drivers are not always easy/smooth.
