Hey guys,

I finally got the means :spend: to put together my build i Got the 18 In Fi Q (dual 2 ohm, loaded) and a Behringer Europower ep4000

Although im lost for a box build

I thinking Mdf 3/4 or 1 in i cant decide ive been told 3/4 is fine cheaper and more easily obtained at a HD or Lowes

I was thinking sealed Cube or Rectangle box

Ported or Sealed ive go the power for a really nice Sealed i herd the Sq is wonderful But i do want it to get loud!!! :hsd: :yikes:

Use is primarily music but for movies or HT too, but mostly for playing music and Bass Guitar(if i can?):dontknow:

and screws counter sinking all these i need some advice.:huh: :dumbcrazy: im kinda lost there

Also Veneer i was thinking something cheep with just glue and iron on, but if too much cost im going to just stain and put protective coating

Also FIBERFIL Lost there i dont know how much and how to put in

Bracing i Herd that was important and Graham did a great job i was thinking a box like his but cut in half???

here a few design some fellow shacksters did that were awesome and i would like to partially replicate with advice thanks

I really liked the Maelstrom build by WillyD

Can you have a look at my graphs in the link below and give me your thoughts. I am not getting any tones from frequencies 10 and 20hz at all. I have purchased a BFD but don't have it yet. I am a bit concerned with what I am seeing. I haven't added the fiberfill but will do to see if it makes a difference.

I do have a couple of massive peaks which I can fix with the BFD but its the low stuff that I am not getting.

Is it ok to fit FI Q18's into 25mm mdf using 30 hex bolts and T nuts. I forgot to double up on my inner panels for them.

cheers
