I'm sure a lot of could say that..I know I can

My recently purcahsed system is in the original post of this thread.

I just bought a component system: Diamond Audio like my subs->

I will be powering them with my old Rockford Fosgate Punch 250aii amplifier, 62.5 x 2 at 4ohms.

I have started on the install and it's a piece of cake (I didn't make my box though).

I doubt I would have come this far had I not decided to start posting here again.

I'm posting now mostly because I am excited, can't wait to get everything in...

Hum.

Got the info notice from UPS, apparently they missed it, and they will be coming tommorow. I need it pretty bad too. I plan to install Saturday.

that 1cu foot box is just fine for a sealed 12" sub.
people have these odd notions that you need huge massive boxes to make a sub work properly.
go with the manufacturer's specs. They built the sub. They should know what works.

Yep, and in a ported enclosure you don't have to give it as much power to get it moving or to get equal volume out of it as opposed to a sealed enclosure. Check out the recommendations for sealed/ported on Diamond's website (assuming they have that stuff on there).

The box they reccomend is fine we have one of these in a small ported enclosure and it does great and its freaking loud. does mid 130s its a 10 in a .75 ported box tuned to 36hz. in a 02 liberty on an xtant 121M its getting about 200 watts. imo a sub will last just as long in a good ported box as to a sealed box.

[quote="Bwcad1"]that box cf will be fine. but you wont get full potential out of those subs.[/quote]

sorry with all the questions just want to gain understanding...

So, do you mean it won't meet it's potential because it's sealed as opposed to vented

or

do you mean that it will have higher/better SQL in a bigger sealed enclosure?

Also, if it is the case a bigger sealed box will be better do you think they recommend the box so small perhaps because it will make the sub last longer (or I guess I am trying to ask why would they recommend it so small if a bigger sealed enclosure is indeed better)?

Thanks

that box cf will be fine. but you wont get full potential out of those subs.

Yah, I was wondering about this, cause the RE SE recommends a 1 cu ft for 12".

[quote="OnYrMrk"]if that box was truly for a solo 12, you are looking at about 1.0cf of airspace per sub. Check the requirements for the D6 subs, I highly doubt that they will perform in such a small enclosure. Mind you, that box looks as if it is made for the old solos, you know the good ones.[/quote]

Diamond audio recommends only 0.875 cubic feet per sub

....with the 3/4 board dividing the chambers in the middle and the 0.1 cubic feet displacement of the sub it approaches that manufacturer recommendation very closely

(box dimensions: 30"W x 13-1/2"D x 13-1/2"H equals 2.375 cubic feet internally divided by 2 equals 1.1875 then subtracting for the chamber divider and sub displacement that's pretty close, only a tad bit bigger than the suggested 0.875 cubic feet per chamber/ per sub)

Please let me know what you think/ what you'd recommend
