Really that is same for me, kids/life/work/yada-yada during spring/summer/fall, winter seems time to get this stuff done.

Buy yourself one of the newer calibrated USB measurement mics, there is a great thread here to support and guide you

+1 on KERG K4MS system, I've used mine for countless applications once I got it.


Thanks mtbdudex,

Those USB mics look like it would greatly simplify the process. Which one is top choice? The Dayton UMM-6 or the MiniDSP UMIK-1 model?

I'm looking to take on building a DIY sub as outdoor projects move to indoors this winter.

I ordered the DIYSoundGroup Sealed Flat Pack 4 cu ft Subwoofer Box:
http://www.diysoundgroup.com/subwoofer-flatpacks-2/sealed-subwoofer-flatpacks/4-sub-flat-pack.html

For a driver, I'm going with the Dayton Audio RSS460HO-4 18" Rerence HO Subwoofer 4 Ohm:
http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=295-472&scqty=1

For the amp, I'll be using the Behringer EP4000:
http://www.parts-express.com/pe/showdetl.cfm?partnumber=248-748

I was going to use the square speaker termincal with Gold Banana Binding Posts:
http://www.parts-express.com/pe/pshowdetl.cfm?&Partnumber=260-284&scqty=1

I'm still a complete novice in this department - so treat me nice. smile.gif

LOL for some reason i think the word novice coming from you in this thread just does not go together at all smile.gif

i am looking into building a sub very soon for my space was actually look at the full kit from part express i think the guy from DIYSoundgroup now supplies parts express with some of there boxes so you maybe able to ge the box and sub all in one kit http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-7094

I saw some kits on parts-express but I didn't know they were actually from DIYSoundGroup so I just glanced over them.

I already placed an order for the kti from DIYSoundGroup, but it looks like after doing the math, I would have only saved $5 after shipping by ordering the entire kit from Parts-Express. Parts-Express charges double the price for shipping as DIYSoundGroup. It may just be because of my location relative to where they are both located though. So others may save even more.

Hopefully you start on yours before I do so I can learn from you. smile.gif

I've decided I'm going to call my HT project Cinemart, whereby I implement as many redneck knockoffs of this masterpiece as possible.

Saw a quick picture in AVS main page and said "hey I know that theater "...

Congrats on theater of the month Mario. Obviously it is well deserved too.

After getting some parts in my shopping cart for the DIY Sub build from Parts-Express, I realized that you can get free shipping if you spend $500. So I ended up ordering a second kit and driver that Snickers posted:
http://www.parts-express.com/pe/showdetl.cfm?partnumber=300-7094

I saved about $100 with the Free Shipping on the second sub so I thought it was a good opportunity to do it now rather than pay shipping twice if I decide to do another down the road.

I believe what you are describing is a "House"Kicker rather than a "Butt"Kicker smile.gif

Take the wheels off that bad boy and shake it to the ground! It'll feel like a freight train instead of just sounding like one.

mtbdudex,
I still have yet to revisit REW room measurements. Now that winter is approaching I'll probably tackle that. Another local AVS member has offered to help me out in that area. So I'm anxious to see what improvements can be made.

I don't know what I'm doing but I'd love to help out and learn REW with you guys. I can bring the beer! cool.gif
post #2833 of 3008
Mario (and all others who are interested),

Please join our REW thread here on AVS and we'll get you going in no time.

http://www.avsforum.com/t/1449924/simplified-rew-setup-and-use-usb-mic-hdmi-connection-including-measurement-techniques-and-how-to-interpret-graphs

As for the mic, I strongly recommend the UMM-6 mic ordered from Cross Spectrum Labs as you'll get a truly individual and accurate calibration for 0, 45, and 90 degree orientation all the way down to 5hz! It's also the same price as ordering from PE.

If you do choose the UMIK, Herb at Cross Spectrum Labs also sells it, and again, it's the same price as ordering direct plus it ships from the US instead of China!

Hope to see you in the REW thread. Read AustinJerry's guide to get up and running and be sure to ask lots of questions.

I've enjoyed your build thread and would absolutely love to see measurements.

If I can be of any assistance, please feel free to PM me as well.

Thanks,

--Jason

Your theater room turned out Amazing! We are looking at building a house and want to include a room similar to yours. Since it is new construction, we can do just about anything. Any suggestions that you can provide would be greatly appreciated. For example, now that you have tried things, how would you do columns and acoustic panels? Would you do anything differently in hindsight? Thanks in advance!

Thanks Jason. I will head over there once I pick up my own USB mic. I'll see if I can unload the other mic and accessories I bought last time for REW on eBay.

So - sounds like the UMM-6 mic is the way to go from Cross Spectrum.

I spent the last two nights assembling the two Subwoofer kits. While waiting for some pieces to dry on one of the kits, I decided I would take the dry one and see how easy or difficult it would be to maneuver it into the front cabinets I had planned for the sub.

Turns out that it's an extremely tight fit which I was baffled by since the subwoofer kit height was supposed to be 23" and my M&K is 23" plus the feet and I managed to get it in there. My opening height is 23.75" which I knew before hand. I was trying to figure out why it was so tight and I hadn't even put the rubber feet on the bottom of it yet. After measuring the height, the subs measure 23.5" instead of the 23" that was listed on the DIYSoundGroup website. I sent Eric a message so hopefully he can correct the dimension error so no one else runs into the same problem.

A little bummed about this since I really don't have any other options. If I were putting them in the back, I would have gone with the smaller sub kits.

I have a little more space once I get past the opening because of the trim. Approximately an extra 1.5" high I believe inside the cabinet.
But because of the tight squeeze with the extra half inch, the sub has to slide perfectly parallel to get through the opening, which will be a real challenge when the driver is in there and the entire cabinet is fully assembled.

So I was thinking I could put a 3/4" board on the floor of the cabinet to raise me up to the same height as the bottom trim to prevent damaging it as I slide in the sub. Then I'd have to figure out a way to get some rubber feet underneath them to prevent it from sliding all over the place and transferring energy to the platform. Which will truly be a challenge given the tight quarters and weight of this thing.

I took lots of photos, but I was planning on posting them once I was closer to being finished in one post. Lost some wind in my sail though. frown.gif
post #2838 of 3008
Ugh - Sorry to hear about that Mario. At least it's a minor (although certainly frustrating) setback. If you need inspiration for a fix or to put the wind back in those sails, review the last 95 pages of this awesome thread and I'm sure you'll think of something! smile.gif
post #2839 of 3008
It took several days to take this build in. I'm sure you've saved me from countless mistakes. My build starts this January finally. And yes, seems like quite a few people from the Racine/Kenosha area!
post #2840 of 3008

Great design and execution, Mario

 

I'm curious if the dark colored Masland carpet and stair color has proved difficult to see the steps when the home theater lights are low. If so, have you found a solution, to prevent stumbling?

 

Cheers!

Robert.

JonMass,

Glad you made it through the entire build.

Good luck on your build and hope there's a few nuggets in here to help you out.

Great to see another Kenosha/Racine local!

Thanks Romans828,

It would have been nice to have a little more space in the back of the room to incorporate the back bar.

Another layer of drywall might have been a good idea. The room does a fantastic job of keeping the sound out, but when the subs hit really low, there is some vibration / sound to the floor above. It almost sounds like distant thunder. I believe another layer of drywall may have helped with those lower frequencies. It doesn't seem to wake the kids up, but it bothers my wife that it could wake the kids up. smile.gif

I probably would have also built the sub floor below the D-Box platform isolated from the rest of the floor. Again, just to prevent the transfer of energy to the rest of the room.

I'll probably look at seeing how I can incorporate some 3d diffusion and other treatments too.

I'd also probably try to design a room around 4 subwoofer locations...one centered on each wall. It wasn't possible in my scenario due to the location of the rear door.

Yeah - I think I'll just have to leave the feet off the subwoofer's, slide them in very carefully, then try to slide some rubber feet under them.

People say that is the best configuration sound wise...I just don't know where you could put those side subs in most rooms. A column would have to be huge for most high end subs. I've wondered how a bar in the back would impact a sub back there.

Second best is 4 subs, one in each corner. That tends to be easier to do... Of course, I have 2 subs and they are both up-front because I wasn't planning on a 2nd sub when I started my build. I wired the room for it, but based off of looks and layout of seats, etc, and not performance, and ended up with both subs behind my front screen wall.

I still had a nice performance (as in quality of LFE, not quantity since my first sub was plenty powerful without even using 1/4 of the gain) bump acoustically by adding the second sub.

Maybe V5.0 of my theater (it would have to be in a whole different house, and I honestly don't want to think about that now) I will plan for better sub placement.

Getting subs in the mid-locations would be challenging for most rooms unless you really had some wide space to work with.

I did wire for four subs in all four corners. The only downside is that the two in the back would be visible in the room. So I'm trying to avoid it unless I find that the sound is that much better.

I'm currently building two of 18" DIY subs and that will give the opportunity to play around with 4 locations. Ideally though, I'll just place them in the front cabinets hidden out of sight and not have to sacrifice too much sound-wise.

I've been tossing around the idea of building a sub for behind the back row that would double as a small bar height table too.
