making a phase plug?

[nerd of nerds]

hello, i was wondering how you guys make phase plugs... i've been wanting to experiment with some on the parts express buyout drivers (4" full range) and need to know how to make them...i do have a laithe but i've never used it before...(its a part of the shopsmith i own)...

suggestions? is it something i can just buy cheaply somewhere?

thanks!

I have used the ends of curtain rods. You can buy them in home dipot or the like.
There are in metal and wood, I could not find sonical defference.

kewl! would you be ever so kind as to post some pics? what diameter are they? and how much do they cost in USD?

THANK YOU SO MUCH!

i read that material doesn't really matter that much, but shape does...

i was thinking of carving one out of wood to the right size and spae then casting a mold of it and making them out of clear resin (very similar to epoxy)...would this work well? it seems that it would...

[nerd of nerds]

anyone want to give me some better answers? some cheap alternatives? i still think i'll go the mold rout since that wal i'll be able to make tons of em easily and i can do spiffy things with em...

so...any ideas? i just need to construct one of em then i can make the mold...

Try searching a bit. I know Timn8ter has made them for his speakers. Actually, someone else may have made them for him. Don't remember.

His were made of wood and cleverly used a pair of tiny steel screws in the bottom so the speaker magnet held it in place.

I don't know that you even need a lathe. You could probably make them using a drill as a makeshift lathe especially for a driver as small as that.

What is a phase plug?
What does it do?
Ideally, it is an object placed in front of your driver/speaker which interferes with the sound paths.

If you look at your speaker, you'll notice the potential for different sounds coming from different parts of the speaker 'driver' itself.
Different locations of the driver have different distances to travel to your ear.
The phase plug attempts to equalise the distances travelled.
This works great for horns or for single listening locations.
But it *could* make matters worse for other listening locations.

So, learn more about what you want your phasing plug to do

more that a few posters to this forum can speak to the efficacy and quality of Dave's product.

If you are in a hurry for a phase-plug, just look in your toolbox for the right size socket

Have a look at Decware here

.. but I think the plugs from Dave/Planet-10 look a liitle better.

...or, as soon as you have found out which diameter you need, carry a caliper gauge with you wherever you go - you'll find dozens of shapes that might be worth testing.
