What glue are you using?

Hello again.

I have take a time out by the discussion by refoaming the midrange of the pentas.

Where can i buy the best ringgs for the pentas.

Leslie prefer the Good hifi.

Beobuddy meansnthat Good hifi is not suitable enough for the pentas.

Are foam better.than rubber?

Is it possible to buy pretty new midrange drivers?

And some another question.

What is the best  receiver to usewith the pentas.

Beocenter 9500 or beosystem 7000 or beocenter 2300/3000 og 3200

Someone who has tester the pentas with the beosound 9000 og beosund 4?

Will the choose of different receivers influence of the soundguality?

He never tried them but his explanation makes sense. To me they still sound pretty good (hifi)🙂

I don't know, the originals are foam so better stick to that

I bought 8 new drivers three years ago for approx. 300 euro. Not sure if they are still available

In my experience, yes

I have here 10 rings from Good Hifi laying here.

I tried to start with refoaming, but already at the beginning I saw the shortage of the diameter which gives you only 1-1,5 milimeter for gluing on the outer ring. At the chassis of the speaker itself, there is a gap which gives you even less for gluing.

A moment later I saw that the inner ring doesn't fit properly at the conus, so I decided not to go further.

Okay, sell them to me if you find them useless (for a good price)😕 You have my number!

Maybe it's just with me, but here why I won't use them.

First the diameter, which is to small.

Then you can see that the ring doesn't lay on the conus, you have to force/bend the ring to fit properly. That's causing the pre-tension.

And then there is the gap in the outer ring on the chassis.

Because of the less space for gluing, I am convinced that one day the ring will come loose from the chassis because of the vibrations of the conus and speaker itself.

Sorry for the bad quality of the picture.

And that's why I'm not convinced about the reliablity of these rings. Refoaming is fine, but not for me. Sorry.

I have had people/members over here for overhauling the penta. It costs them quite some money. Mostly for the (better) parts I use.

But with such an investment I simply can't suggest refoaming with these GH rings.

Are you using foam or rubber? Looks rubber to me seeing your pictures.

Link send to GoodHifi. Let's see what they have to say!

Again, if useless then give/sell them to me👍
