Ok guys, slow progress, I just cut the window bracing as below size, it will be placed at 7", 14" & 21" inside the box as MKtheater suggested at post#71, would it to big & occupy too much volume in a 10 cubic feet sealed box? should I go slightly smaller, say 2"? Any thoughts, suggestions & advise?

That depends how thick it is. BTW, it's not necessary to make these one piece, four separate pieces will work just as well.

The volume is rather small between 2-3" across all three so just do what ever size you want and do them all the same.

3/4"x3"x" is not hardy anything in itself.

Thanks guys, three of these window bracing (at 7", 14" & 21") should cover bracing of the middle of the opposing left, right, top & bottom panels, what bracing should I use for opposing front baffle to back panel?

I now this doesn't help now...but If you can, keep a look out at harbor freight adds. Quite a few times a year you can pick up a HVLP sprayer for pennies on the dollar. For random odd jobs, it fits the bill quite nicely. Maybe in a few months you can repaint and get a finish that you like if this doesn't work out. Cheers!

I must be guilty because people say I am guilty because they chose to call me guilty because they refuse to see the truth. Much easier to be part of the mob..

Have a short demo with Pacific Rim, just like what you have said, the bass is thunderous, especially I just feed it with around 1,500 watts power only, same for the Underworld Awakening, the giant Lycan's foot stomp is unreal, it was like it's approaching me eek.gifbiggrin.gif

Need to get a miniDSP to EQ it soon smile.gif

Congrats Werewolf,

Now enjoy!
You'll freak how much better they will sound through a MiniDSP.

Thanks Fatshaft, the difference is really day & night with a miniDSP?

Yes,

My room gave me some pretty serious nulls around 20HZ and 50HZ and major bumps in the 30HZ and 80HZ regions.
I can't believe the difference it made to my sound when flattening the FR with the MiniDSP.
I would NEVER go without it.

Fatshaft, I remember you commenting in my thread about how you had the same FR canyon between 50 and 80Hz that I do because of where the MLP is in the room; 1/4 wave cancellations? My couch is not exactly in the middle of the long dimension of the room, but it's close. Did you end up adding rear subs to compensate or have you been able to work it out using the MiniDSP and positioning/placement/treatment changes?
I am trying to figure out where to best spend money right now. I want to buy two more SI 18's before they are gone but I also have zero EQ (aside from Audyssey MultEQ) on my subs. I can't decide if I want to work on EQ'ing what I have already or just focus on adding two more subs right behind the couch. Either way, a MiniDSP purchase will happen at some point. I am already working on treatments.

Hope this helps...

Here's my graph with the subs in the front


Here's my graph with the subs in the back


Here's all subs (Front and back) eq'd with the MiniDSP


I never tried eq'ing the front subs only to see what I could get.
I also never tried eq'ing the back subs to see what I could get.
I only eq'd with all subs on.
FYI,
My setup is 4x 21's in the back (2x per corner stacked)
2x 18's in the back (1/4 away from the corners)
2x 18's in the front (one per corner)

Without the MiniDSP I have a null from about 15 to 30HZ and easily correct this with the Mini

I remember your thread and saw what looked like to be the same situation as mine.
If you could try the 2 subs you have in the back and take a FR to see if you get results like me.
If you do, you'll see tremendous gain with them in the back.

Good luck
