"Other speaker drivers that still employ paper cones AND paper voice-coil formers are... Fostex FE series ..."
Not all the FE series have paper voice coils. Further, the plastic compounds i add to the surfce of Fostex cones, makes them sound better.

Some of what this guys says makes a lot of sense, some just seems, IMHO, to be taking things too far.

Does anyone knows if the extra surrounds that's
glued on Decware's drivers improves the bass
& sound of the speaker ?

Thanks

Default see other thread

I had a thread on making phase plugs called homebrew phase plugs and was using those 49 cent drivers from Pioneer mentioned above.

But this is about something else:

I was in the hardware store and saw some bullet shaped cap nuts with hex bases. These may have been for auto but I don't think so.

It has the cone shape and are bright chrome color. I can get the
manufacturer some other trip. But what I wondered was if you manage to get the right diameter for (it would have to be one of the
6 in ones like 167e) how would you ever get it _off_ if need be?

Same deal with the nut used by the thread starter. Those have to be
magnetized pretty strongly.

It is weird how when inserting the phase plug you can hear the
sound change as you are finding the sweet spot. I don't know if all that fiddling is necessary with a metal pp.

I haven't tried this, but what I would try is file out thick grooves in the base, so that it effectively sticks on little 'feet'.

-otherwise you could try gluing something (rubber washer, etc) to the base, to weaken the force.

Well, I've worked with wood.

Lacking a lathe or knowing how to use one I've been using little wooden craft eggs (they should be in good supply again near Easter) and a piece of dowel both glued, then shaped to fit.

The brass ones really look good though.



Homebrew phase plugs


The Planet 10 lipstick tube suggestion is still the best but I haven't been to the Revlon (or other mfg) department to find a right item.
