Default FR taming tricks

I just bought some old CHEAP FR drivers with a wizzer.
Not much good but much better after coating the paper with a couple of coats of PVA, they are a bit harsh at the top end, I remember dave/planet10 had a trich with winding soft wool around the base of the wizzer but can't find the link or discussion thread.
Can some-one please point me to that thread or link.
Thanx in advance.
I only paid $5 for 3 drivers so not much lost if I fail, and it is fun tinkering, I'll do the baskets only if the wool trick cleans up the top end

G'day Moondog55,

Have a look at EnABL - Listening impressions & techniques post.
There is a link to an EnABL kit there as well.

When you see the impact on these, you'll probably want to try
some better ones.

What drivers did you get?

Cheers,

Alex

Isn't that the 98 cent mod? Wool or foam?

Yeah, I tried a search for that but couldn't find it.
The guy used foam placed around the back edge of the whizzer cone.

98 cent whizzer trick... in the original incarnation uses very low density foam (attributed to Marc Wauters -- probably adapted from Wharfedale's successful application in the Super X series).

Use an appropriate size rectangle of foam (ie furnace filter) to support the outer edge of the whizzer against the main cone.

Note: a lot of posts while i was typing
