Hi Francis,

1. is the rubber strip put at the edge of the PVC back chamber as a
cushion for the horn to sit when it's bond to the ring?

The rubber strip is supposed to be pressed in between the horn wall and the edge of the back chamber.

2. using the glue alone, is it enough to hold the horn for a long time? I
mean, would the screw goes all the way through to the horn too to hold it
here when we drill in onto the ring?

Yes, the glue is strong enough to hold the horn. Please do not drill all the way through!

3. after we push the ring in to the back chamber and before we apply the
glue to glue the horn, you said to add "silicon sealant". Is that to add
around the ring touching the PVC back chamber? If yes, then which side,
the side facing the wood (back), or the side facing the horn? Or both? Is
it for securing the position of the ring, or for air sealing?

The silicone should be in between the mounting ring and the PVC back chamber. This to secure the position of the ring before drilling and using the screws to secure this permanently.

4. I see in the photo on the instruction manual that you have some sort of
foam/rubber strip directly on the inside alignment of the ring, seems to be
for driver to sit on it; is that extra? Should I put something like that
before I fix my driver on?

That foam is of no use for AER or Lowther drive units, I should make a new pictures....

5. I might need to drill holes on the back chamber to attach a mount there
to mount the back chamber to the base box; is it ok to drill into the back
chamber? What kind of precautions I should take?

Yes, you can drill as many holes you like as long as you have them closed again with the screws to mount it to a stand or your bass box. Have the woolfelt removed when drilling though..

Ciao,

Bert
