Default Order of panels in Tympahni 1D

hi after i demolished my knees by sitting on the ground for 5 hours i just rewired (foil exactly 8 ohms total 50 meter of foil ) one channel of the tympahni 1D form magnepan, sound is ok, not the best i heard but i thnik its mostly because my room, its just to small for these beasts.

but im wondering if the setup is correct..

for now it goes for the left chanel according to magnepan Tweeter on outside, then bass panel then bass/mid panel. but i wonder if this is correct. it makes more sense to me to have from left to right tweeter midbass then bass. also the wire is facing forward , is this normal >? or am i running bass and mid out of phase with the tweeter>?


i tried googling but io see different configurations.

Ps bad foto but you know what i mean


or is it because the bass panel is facing away from listener so the mid bass is the third panel wich faces to listenen again.

I am gessing that the wire was bad on the panels?
I have found the the foil has less output than the wire,on the Magnepans... i have re-foiled some older MG1c,foil vers wire on the two 1cs speaker gave like 2-3db less output with the foil,but the newer magnepans have the mylar to the front.
The older 1cs were on the back....Thanks for the post an pix...looks cool...cant help on the panels setup!....but magnepan would know...but try them every way see what workes for you.

On the T-ID I rewired, the wires were towards back. It sounded correct that way with the tweeter panels - I think your nulling some frequency and your panels are out of phase. I will check my pics tonight (sold them)

Whichever panel (bass or mid) that have two sets of wire holes the bottom is the panel that goes goes in middle. I remember it to be the mids?

Also, you need to give them some time and drive them with a good current amp. It took a couple hundred hours to sound good.

Ah Yeah stupid of THE one with 4 connections shoul be in mid this is THE bass panel by the way so the setup is correct. Only wich side should be on front. I can ofc measure the phase. But some designs have the tweeter out of phase so or still does not tell me if it's correct. I tried both and to my ear wire in front sounds best. But then again I'm not used to the speaker. I kept the original layout on the coil. I've seen some images of a 1d online where the wire is on the front to but this could be modification, some people prefer the wire side although if I measure it really does not matter.

Hmm burning IN i think
In my case is snake oil , the mylar is the original and the coil is foil instead of wire, also it lacks the half a kilo of glue. I will measure them soon to see what it did to the resonance , but I bet its 40 hertz , wich according to the frequency response of 40 to 20 k should be 40 or less.

I think it more getting used to a sPeaker in this case or find good placement, wich is a nightmare with such huge gigantic ugly doors. I finish the second check if everything is accoRding to spec and then prob sell fo a WAF frendly DIY project

If you are selling them, Roger Gustofson was interetsed in my T-Ids. but we couldn''t get the shipping done cost effectively - he is in your neck of the woods...

I think mine actually sounded a little better after a little while - maybe the glue /wire / mylar finally setting up?

I did not use a lot of glue on the panels, but I think the amount of glue weighing down the mylar is a lot more important on the mid / tweets. I used very little glue on my T-IVa mids...

ok i measured both responses and i must say they dont differ much werid enough. when i look at the phase response. it slightly moves but not what im used to see from 0-180. i forgot to save the repsonse so i will do it again. but i did save a response of the resonance frequency with foil instead of wire without the glue. and by the way jesus these panels can play loud and low, its insane.


as you can see the resonance is where i expected it to be slame in the middle of 40 hertz this is a close measurment of the bass panel. i did measureed a full range signal so thats why the response from 400 and up is so weird, (because theres another pannel next to the mic as well)

If I remember correctly, these are a 2 way, simple 6db butterworth crossed over at 1000hz...

I really liked mine....
