The combination 24/40/8 does the same job. And the template can be any shape, as long as the smallest radius is >20mm.You have to sand it a little bit, otherwise it will fit too tight and you won't get it out again.
BTW: Trend and others (sautershop.de in Germany) sell collets that convert a 20mm guide bush into a 40mm guide bush, so you don't even have to change it.

Default Felt damping material

Hi, I bought some of this Speaker Carpet - Light Grey - Jaycar Electronics which turns out to be a synthetic felt rather than wool/cotton. I was planning on using 4 layers which gives around a 1/2" mat.

However given its synthetic (you can tell when you burn a small piece) should I be using it or try and fine some wool/cotton felt? Having trouble finding any locally tho I may look to pulling up some carpet and using the old style wool underlay.

Thanks

Surely scissors and a passing sheep would supply the necessary fibers

I gather that the stuffing behind the baffle tightens up the bass, but what effect does more stuffing in the V have? Going to seal them up forever on monday and I am having a nervous about it

1st off, you need a dedicated washing machine, and it should be out doors.

I had read,and tried, the packing, sealing with weather stripping,listening, adjusting and then sealing method
weather stripping with an adhesive back is the **** to remove, i resorted to the belt sander and then had to remove stuffing! I a little wiser as to re-stuffing, BUT
Make the top panel removable.....Its the best solution

Anybody building these and wondering about how much punch they have, just finished Motorheads "ace of spades" album. Last track "the chase is better than the catch", thru a 50 year old 10 watt valve amp.I could FEEL the bottom end, see it in my wine glass. Not my first choice of music but it was TIGHT thumping bass, no mush. I wonder what it would be like with really stiff cabinets.
