To bend it vertically is a mistake.There is loss of spl. and worse, loss off spl.in low freq.
Butt i vill still bend it horisontally .

Båndsei, you never gave a description of how these speakers sound? Do they give you a 3-d image? Are they holographic? What do they sound like? What speakers do/would you compare them to?

båndsei, do you make a kit of your project, so that other people can try them?

I like the sound of ribbon speakers,but i want to make a "fullrange" speaker. It dont have to be high end just hifi.I wanted to elliminate the hot spot,and I did that.Now i will make a curved planarspeaker 20X115cm.[IMG]Click the image to open in full size.[/IMG]

Bandsei ,

It's interesting to see your attempts , as I'm also playing around with a similar steel construction , the difference being , flat as oppose to curved and push pull for better full range operation ...

Which glue is good for neos and aluminium? Last night I have used polyurethane with 10kg load. After 24 hours it's still wet! Anyone tried anaerobic glues?

And from behind.The subwoofer has a 15" passive radiator in the bottom,and it seems to be easier to match it with the panel as it is "tilted" 45`
It dosn`t go as deep as my first panel but deeper than my seccond one.This one is wider and not as curved.
I use iron and dont have to glue the magnets,and if i had to,i would`t use too strong glue becourse i will be able to remove them again.You could use silicone but not with accid, use one with alcohol regarding the aluminium.

I like the look of my newest planar ,and it is rather easy for me to make metalwork.I have the right tools.But i want it to go deeper,or maybe reduce the output in high frequenses.
Would it helpe to curve the membrane more, and wich radie would be the best??
The speakers from Martin Logan have curved membranes,what radius ,and how wide are they.

Hello Bandsei,

Getting good bass out of your planer will take some work. Take a look at Magnapan l planers , i really can't see you getting good bass without going hybrid or to a large push/pull planer arrangement ..
