I thought it was a ground loop problem, but sounded high frequency. So playing with the filter it seemed like it was in the 2k range. So I just set a filter to kill everything above 1k. Since the sub only outputs 15hz to 90hz Im not missing anything. The buzz/hiss is now completely gone. I suspect the DAC in my receiver is the problem.

You should be blown away by it. Mine has surpassed every expectation I had, although I have reached the limits of it and already want more. Its worse than drugs. biggrin.gifwink.gif

And, I've not tried that demo music yet. Kind of scared cool.gif

Ok, I am sorry I am a bit slow but I still don't understand. Why would your subwoofer amp be doing anything with a frequency int he 2k range? Isn't it connected to the subwoofer output of your receiver and isn't the receiver set to send out anything from 90hz down? So is it that your crosssover inside your receiver is no good and it is sending everything to the subwoofer amp?

Right. But the DSP in the receiver isnt ultra high end. So at loud volume there is background noise which trickles to the sub amp and then to the sub. The woofer isnt moving, I think its just enough to cause some air flow. At least, this is my theory. Its the only way to explain why I am able to filter it out with the inuke DSP and why the noise raises and falls with the receivers volume.

Ahh, probably same thing that is happening with mine when I do REW tests. I have to disconnect my mains because when I send the pink noise through even when selecting 20-90hz I still hear noise coming from the mains. Thanks for the explanation.

Have there been any photos of anyone that has put together a MiniMarty? I've got a Marty Cube and seen the photos of the full Marty but just wondered about the MiniMarty. I'm thinking of getting another flat pack from Donny and I'm kind of undecided if it should be a matching Marty Cube or something else.

Now that I have all the electronics for the time being I need to make a stereo cabinet for my amps ,oppo ,and emo. I'm going to use mdf , put the thick veneer on the sides and top and paint the shelves. Going to use cherry and something else. Leave the back open for ventilation. Going to try a curved seam were the woods meet.

Not sure if you seen Erich's new flatpack. Will be a lot cheaper then mine. I have no problem making you another.

Donny,

Yes, I have seen Erich's design and I'm considering it as well. I like the look of my first Marty Cube that I might want to add his bigger brother or his identical twin though. wink.gif

I finished my stand build and installed all my equipment yesterday, so next on the list.

I think I'm going to buy the Oppo 103d first before the 2 Martycubes. Besides, maybe SI will get more HT subs in by then.

Right now cable on tv only. I have used cable on the projector but did not hook it up that way yesterday. I'm waiting for the Oppo so I can feed my cable thru it then out to tv and projector. Then hdmi 2 on the projector is xbox. Right now hdmi 1 is 3d Blu ray.

The main reason I got a projector was for the movie like experience and it's been awesome so far. We try to watch a few movies a week on it. Last night my son had his cousin over and we watched Titanic (cousin never saw it). He said it was better than the theater. Also it helps to have a concession stand and popcorn popper.

Only hdmi 1 out of oppo has darbee. It will make a huge difference on the projector. cool.gif

I've been trying a Darbee with my JVC RS45 thanks to forum member stsand, it's a noticeable difference but I prefer it set between 50-60%. Any more then that and it starts to look too artificial for my tastes.

I'm at 68% with edge enhancement +3 , smoothing +1, detail+4. It depends upon your tastes and your source.

Blur,

 

This looks like really good.  I like how you took the space and fully integrated all the best HT elements - surround sound, projector, yet the room still looks super comfortable to hang out in and be part of the home, whether a movie is playing, or not.  

 

Nicely done!

I agree with the other, this does look awesome. Very clean, something my wife could live with. I can't really see it, but how did you hang your screen and where is it once you are watching your tv?

I'm sorry, in the picture with the tv on the screen is just out of view above the tv. If you look in the first photo you can see the screen casing. It is a 100 inch elite screens motorized. I have 8 ft ceilings so in order to have the screen come down to where I wanted it ( 1/2 inch off stand ) I have the screen attached to 2 2x4's. The 2 x4's are attached to a 1x4 that is then mounted to the joists. I had to build it this way in order to center between the windows.

Now that the stand is done I'm going to build a matching valance to hide the screen. Just to give you perspective the stand is 85 wide x 26 high x 22 deep. I'm going to start a thread soon with some photos of the whole build. I have full fan cooling system with temp sensors in each enclosure. Plus I have an automated fan system for the xbox itself. So when it gets hot they come on. The other fans are triggered from my avr to my power centers. Then switches on my fans and 3 12" subs. Also it's all lit up with led strips.

Yes, the wife really loves the whole room now. She gave me a bunch of crap when I started my sketches. But now it's done she loves it. I think I'm going to make my Marty cubes out of the same oak with the same shaker style design.

I did this all to hold us over until I can build my dedicated theater.

WOW, yes please post some pictures. That is beautiful and I love the idea of fans kicking in only when needed. You do great work, I can only imagine what your theater room would look like. thanks for sharing.

I have looked at the DIY for a long time and this thread is what has really caught my attention. One it is pretty simple to build and has a great look. Plus the output vs money. I can't wait until I start mine.

Donny, I would really like to second this comment!!
I remember when I first asked you to make a flat pack and you came through like a real business man!!
When you said you would build one, you did...that goes a long way in my book and will only be buying and more importantly, recommending Marty cube flat packs from you!!!
I think a lot of people have no idea how important it is to build a speaker box properly especially when you want high performance!!!
Once again Donny, thanks again and I will be in touch with you to build me some more flat packs when the time comes...cheers!!!

Thanks for the kind words guys. I like to think of this thread as a general thread where questions about subs , sub amps , cables , and finish can all be discussed.

Looking sharp! Thanks to LTD02 and you and all the others for this and related Marty sub threads.....they are going to make my project that much better and easier.

I fully sanded my big ass marty sub cube on the weekend with help from my son:

I moved it to the garage now and I want to paint it!!!

I want to use duratex as a last resort but I am thinking of flat black from Rustoleum.

I have 2 cans of BIN primer sealer with 120/220 grit sandpaper for my orbital sander.

Since its still cool here in Mississauga, i thought i would start on the bottom of the sub and experiment since no one will see the bottom anyway.

Any input would be much appreciated....

My input would be to mix water and yellow glue 1:1 and paint it onto the edges of the MDF. Let it sit for a couple hours and then sand it. Do this twice if necessary. If you don't treat those edges right, they telegraph through the paint job and you'll get lines all over your sub.

Also, that is going to take a lot of paint. Go as far as you can with the primer. The primer will help with the edges too. It's all about prep work. Get it looking good with the primer, and then it'll look good with the pain. Believe me, I'm going through this right now on a build. Major pain in the butt.

Looks great so far!
