Fonken floorstander MKII

ecir38 · 14th January 2008, 06:43 PM

Yesterday I was looking over some designs and I just can't make up my mind. Right now I am leaning toward the Sachiko but don't have any past experience with a full range driver. So I just said screw it and decided to build the Fonken MKII for the time being to use as a basis to improve on.

I cut out all of the panels with some wood I already had and started glueing up today.

I ordered the drivers today and should have it finished within a couple of weeks.

One question I have is I am thinking about using a roundover on the baffle and a wondering if this will be OK.

Also while pondering on what to use to fill the base I noticed I have a bag of quickcrete mortar and thougt this might not be a bad idea to use. Just mix some up and pour it in the void them install the baffle after it dries. What do yall think?

Seems like you might get a rattle between the final panel and the quickcrete. You might be better off just putting in there san water, just using the weight and deadness of the powder suffice.

Aquarium sand, lead shot, or glass bead blasting media all work quite well.

I think it's a typo of "sans". French words are often co-opted into English, but there's no guarantee that they will be spelt correctly.

Thinking aquarium sand might be the ticket since it should be easy to find and hopefully sterile too. Thanks

Ed from The Hornshoppe has used BB's to good effect. Not too expensive, not poisonous like lead and you can use a magnet to fish them out if you want.

LOL
Why I am not surprided that Ed has a use like this for Ammo?

Does sound like a good idea though

Take care,
Robert

I'm sure Ed has "used BB's" to his satisfaction in places other than speaker cabinet voids.

I use kitty litter. Cheap and easy to use.
