completed construction of cabinets for 12" CF AN

tsiros · 02:12 PM

(click)

20mm plywood

I now just need to remove the drivers so that i can add sticky foamy thing tape between driver rim and baffle.

Also, line the interior with acoustic dampening material

Instructions say to use fiberglass, but i'd rather not... What commonly available material is suitable? Also, do i cover all the surfaces with it? All except the baffle? Only the upper half?

I'd appreciate any and all advice

p.s.: they sound very well.

Looking good! I assume that polyester [polyfil], wool or cotton batting is available locally, so lining the top, back and one side to about 1/2-2/3 the way down should be sufficient.

thank you for your input!

I will try out different types of material, see what sounds better, I think it is important to see how the cabinets interact with the room.

frankly i don't think i will hear any difference... these are the first serious speakers i ever hear so i am not well adjusted to hear such small differences. Yet

Great stuff. So how do you like them? Is that the 5.6 cabinet.

A nice clean looking pair of speakers !

we want more photos

p.s. I didn't find polyfil very good in my last project. I'll be trying felt and wool next time.

pretty

@ Melon Head : Indeed it is! I used 20mm plywood instead of 18mm, adjusting the panel dimensions to keep the internal volume and dimensions the same. They sound great. Haven't heard other big speakers to compare, but as far as i can tell, they are the best speakers i've heard so far in my life.

@ Bigun : i will try all three and see what sounds better... until i sand them and paint them you will have to be patient for the photos

thanks to all for your comments

I will see if I can build up a 5.6 this weekend

I actually like the look of them the way they are. Just natural Birch ply

from the front they look gorgeous, granted. Especially the combination with the black driver and the copper center of the driver.

but there are screws visible and from the side you can see the profile of the wood panels

so i need to sand them, apply wood filler to cover the screws and then paint them, but that must be done after i decide what filler (if any) i will use
