Comparing Push pull 6mm xmax to single ended (magnets only on the back) 6mm xmax or single ended 3mm x max. with an eye on having to make them bigger anyway
sorry for the really annoying mic from my headset. its like scratching nails on a chalkboard :(

Not boring at all, thank you great info.

The curve is also good to know where you are, but for me often a linear curve means that I don't have bass and treble and the mids are far in front, from here I deduced that it is best to set them according to my ear! I like to follow you because I want to switch to mediums with ribbon, I heard from a friend and the mediums are much more open and clear on ribbon. Anyway what you do is very important to me!

I would be interested to see how two or more panels work together. Take all the best of a single panel design and increase the surface area over multiple panels

@joppepeelen Месяц назад

A bigger panel would be less work :)

Thank you for the awesome and unique content Joppe! I suppose you already have mids/tweeters figured out? I am wondering if you tried to build something similar to Jazzman ESLs?

@joppepeelen Месяц назад

thanks m8, well something like jazzman , you mean an ESL ? i was talking to the owner of a dutch ESL company if i could buy 2 of his panels they use in their commercial setups. (i could make them myself, but... well much work) since i made a ESL magneplanar combo once. and its a pretty nice combo :) i could make an esl in the future myself problem is finding affordable transformers :(

@KamikazeImmortal Месяц назад

@@joppepeelen what are the traffo specs required? I have a contact that can make really nice custom ones and they were pretty inexpensive, so could ask around.

@joppepeelen Месяц назад

I don't know much about specific transformer specs I'm afraid , but a step ratio of 1:100 or 1:125 would be nice and a freq range 200-20khz. There is much more to it of which i don't know a single thing about I'm afraid haha

@be2the4out Месяц назад

yeah.. acpected that.. can you make a screenshot of the Dats measurements of your contraption? or tell the qts and fs of the measurement? i could 'guess' where you 'need' changes to make it a viable woofer.

@joppepeelen Месяц назад

push pull had a QTS of 2.8 and an FS of 44hz, single ended 6mm xmax single ended had a qts of 3.8 and an fs of 44hz, the 3mm xmax single ended has a qts of 3.3 and a fs of 49. its not a regular driver so they cant exactly be compared.

@be2the4out Месяц назад

@@joppepeelen it cant compare but it still can :) by the Qts it must play to the fs with no loss of output, so i believe main problem of low bass-output is the narrow baffle.. if you ask me then the qts is pretty shabby, and need atleast a qts of 1 then the thd will be lower, but mainly a bigger baffle is needed to seen by the driver. ever thought of making sidewings on this panel? or a H shape of some kind? so; more magnetpower, more copper in the coil/magnetgaps (this lowers the Q more to 1), and acousticly less forwards/backwards wave cancelation, (thus low extension) by more panelwidth/wood/sidewings/H-shape etc or boost everyting down low and play low volume, there is no other way i guess

@joppepeelen Месяц назад

@@be2the4out no bass planar magnetic or ESL will have a q of 1 :)

@joppepeelen Месяц назад

We could at major costs. An esl63 has a q of 2 . As an example :)

@josephpsmithe Месяц назад

Excuse my inexperience with these, but what would happen if you put it in a sealed box? Will it help over excursion down low? How would the bass response change?
