speaker fitment
speaker fitment
anyone know if a modern 6" x 4" speaker will fit (without any hacking, of course) in the front oval speaker hole of a 1969 912?

Re: speaker fitment
Hi Adrian,
the dash takes a very specific and non-standard sized speaker which is why they are normally an exorbitant £80+ each.
The 6" x 4" is smaller than the aperture / fixings so you would need to make an adapter plate out of a piece of ply or similar (or 3d print one).
I made a similar adapter in mine and all works well. It also allows you to choose a better spec speaker than the standard one.
One thing to bare in mind is that a speaker is intended to have a baffle so you really need to fill in the aperture around the speaker for it to work correctly and efficiently.
I've seen people extend the mounts with brackets to match the aperture but that's not going to sound very good.
regards
Andrew

I fitted a new 3 way speaker by modifying the old speaker frame (cone was totally shot) Ian

A Blutooth speaker behind the seat works a treat

Re: speaker fitment
thanks guys, i've no problem making an adaptor plate, but are you saying, Andrew, that the gaps either side of the smaller speaker should be left open (as in Ian's pic) or filled in? i'm guessing, but perhaps the speaker should have a "box" behind it, lined with some sort of acoustic material, rather than just being open to the front compartment metalwork, to improve the sound?

It should be filled in otherwise you don't have a baffle, you don't need to add an enclosure, that's your trunk!Adrian3 wrote:thanks guys, i've no problem making an adaptor plate, but are you saying, Andrew, that the gaps either side of the smaller speaker should be left open (as in Ian's pic) or filled in? i'm guessing, but perhaps the speaker should have a "box" behind it, lined with some sort of acoustic material, rather than just being open to the front compartment metalwork, to improve the sound?
I suspect Ians would sound better with a baffle - apologies but long term hifi buff and all that
