Great to have the opportunity to listen to your prototypes at the Dutch Audio Event in Veldhoven today! Congrats that you managed it to show them to a larger audience now. Next step to produce and sell them? The combined subwoofer (not yours) seemed to be a little bit of an overkill though. Shame I missed you there to have a chat...
Aah thats great to hear ! yeah i was a bit lost in the building, i could not find my way to the correct room again (3 times , its a maze in there) so i was a bit late :( haha hopefully next time ! i must say the bass in the room changed quite a bit near the back of the room ( passing the middle of the room it becomes a bit to heavy for my taste) not the easiest room. to get above all the talking people i think it might have needed a few db extra on the planars?. its a hard balance people needed to be able to talk to in this case. in any case it was a fun experience and i listened to some expensive Planars (goldmund room) to see how they sounded :) hopefully we have a chat next time !
Well i would cut them 24dB at 40 hz in normal use. to give it a bit more headroom :) mating it with a sub could be done at 50 or 60 and you can play rather loud
If you used a router to chamfer the High Frequency Ribbon inside edge, at 45 degrees, you can eliminate the resonant loading imposed by the, "Square", 90 degree, edge, not to mention Diffraction. But you should definitely present them to People at a showing, they sound REALLY fine!
Yep, i was just drawing something up to be able to do that, problem is there is not enough material to do so :) so i drawn up a tiny version to eliminate the line source troubles and make it thicker to have some material to chamfer... to see what the difference is without me making another huge ribbon to try. and rounding of the corners to mitigate diffraction could help to. but is a bit harder. i had an idea of making it modulair. being able to add another bass panel to the other side.. witch is cool. also makes the difraction the same on both sides. easier to filter.. . but it does not make it able to chamfer these sides. well i hope the inside helps at least :) fingers crossed
@@joppepeelen try around over but instead of a chamfer. The sharp edges will create sudden changes in air impedance. Also the 45 degree makes a perfect reflection and that is not good. A round over will eliminate all of that.
well the normal ssss is around 7 khz , but yeah its a bit more feisty , so it could be something a bit lower. in the end nothing has been done towards baffle diffraction here :(
@@thomasyoung479 they are 2 parts non shipable , it would cost as much as the speakers itself im afraid :) its just a prototype (rather ugly to). but depending on what people think of ijt this weekend i might make it a complete speaker. so far i enjoy listening to them
Hey! WTF is going on here?!? These sound NICE! 👏👍They remind me of the DIPTYQUE I heard in Munich in may. How did you make these? Do you post how-to somewhere? How efficient are they?
Well i make similiar driver like they do . Not exactly of course, but similar. The bas panel i made in a video. Somerhing with scrap or left ovee metal in de title... ekse tru scrolling they where made this year.
@@joppepeelen Hold that thought. I live in good old Sweden, so not completely outlandish idea. But maybe wait a bit until you feel you have something really good. I plan experimenting myself once the pre- and power amplifier project is completed
