That is a great sub. You will be very happy with it.

WAIT A MINUTE! And back the truck UP!

Are you saying you're NOT done?

I'm just askin'.

Great choice CJ. Now you have a new Thanksgiving project: Grab a hot glue gun and permanently affix any nick-nacks to their appropriate location!
post #1564 of 1625
Now this is going to be fun. How about one of those fancy time-lapse videos of your Sub build and install.
We could call it "Spud-Vision".

Heck, I've been in mandatory sustainment for a LONG time. I've now opened a new project and separate project to apply an enhancement to the current system. This is a tertiary enhancement to provide additional functionality, but will in no way compromise the existing functionality of base system. These enhancements will require an minor additional amount of yearly sustainment funding, but will greatly enhance the ROI of the entire system. Business case, Business Requirements Document (BRD), System Requirements Document (SRD), Authority to Operate (ATO), Sustainment Plan (SP), and all Project Management Accountability System (PMAS) required documentation is in place. The funding justification, form 2237, and Independent Government Cost Estimation (IGCE) were completed and approved, the acquisition package moved from actionable to ordered...we are awaiting delivery.

How bad will it be? eek.gif The sub will be in the basement. Do I need to do this for items on the second floor too? biggrin.gif

Yes, but did you get the cover sheet on your TPS report?

This reminds me of a sub I had a guy build for my first theater. It was about the size of a water heater and pushed sound into the theater through a 4" PVC pipe coming through the wall in the back of the room. At first glance, the sub looked like a simple in-wall speaker.

When we were setting it up, I wanted to test it with the T-Rex scene in Jurassic Park. When the T-Rex let out his yell, the entire room shook. I looked at the wall when we were finished and there was a crack about 4 feet tall going up the drywall. The guy that built the sub seemed upset and apologized to me repeatedly. I remember my response simply being "Coooooooooool".. smile.gif

My Danley arrived today! I'll be spending the weekend putting it together. I'm so excited!

I'm going to power it with a Behringer EUROPOWER EP4000 Professional 4,000-Watt Stereo Power Amplifier. What will I need to smooth out the response? I keep hearing about a Feedback Destroyer. What will that do for me? I'm going to need to get real smart on sound tuning soon!

I believe the Behringer Feedback Destroyer (BFD) is being recommended because you will need a High Pass Filter (HPF). If I remember correctly the DTS-10 is a tapped horn (TH), which means you need a HPF to filter out the frequencies below the DTS's tuning frequency. If you send a signal with content below the tuning frequency of a TH, the driver in the TH will 'unload' and possibly damage itself. The BFD can provide the HPF as well as other controls you need to smooth out the response.
post #1576 of 1625
CJ, I'm excited for you! Few things... Be methodical about the construction. Dry fit things first and then use the PL construction adhesive judiciously. I've heard of folks with small air leaks that have had major impact on performance.

I use the BFD 1124, which is the cheaper one and does not have a HPF. I've run mine beyond anything reasonable with the torture test movies, and have not have one sign of stress in 2 years. The BFD 26 something or other is the slightly more expensive model that has HPF. Many have liked the minidsp. The 1124 is about $30 used, so it's worth a shot in my opinion.

Be careful installing the drivers themselves. They are heavy and at an awkward angle. It's easy to have a screwdriver slip and go through the cone. Some have done that. frown.gif

Construction by yourself should take about 3-4 hours and the only piece that might be stubborn is the final large piece. For my first one, I cursed for a half hour before it settled in place. For the second, it went right on.

My EP4000 did not like running bridged. If you're running one DTS, you should consider wiring one channel to each driver. I can't remember all the details, but the wiring is very easy to mix up. Ivan at Danley verfied that you really can't hurt anything. Try to get it right and if performance isn't there then you likely have a polarity issue.

Be prepared for lackluster performance without an EQ. You'll hear the potential, but it will be very mid base honky with no deep stuff.

Have fun! Look forward to some construction photos!

Thanks Tony. I've been reading over the Danley thread and trying to plot out how to tackle this dude. I'm really going to have to get smart on the EQ and room tuning. I had postponed that when I finished my construction and haven't gotten back to it until I got a real sub. Well, I'm here now and as bewildered as I was when I finished the room.

I saw a new BFD on Amazon (FBQ 2496), but it's $170. I'll look around for a used on on Ebay or CL. I'm currently a Behringer Europower 4000 amp tp power my butt kickers. I was planning to re-purpose that to power the sub, but if there's something better, I'm all ears.

Thanks for the help. It should be an adventure.
post #1578 of 1625
No use for anything more expensive than the EP4000 for your Danley. FBQ 2496, that's the one I couldn't remember.

So, I purchased the Danley DTS-10 SuperSpud Sub kit. It arrived on 12/6. I spent some time looking over the instructions and gathered the hardware that I would need to build it. The kit comes with two drivers and very nicely CNC'd wood pieces. The builder needs to buy the hardware to put it together. this includes screws, and the wire connection panel, and lots of glue.

When it arrived, it was packed very well and the box was mounted to the pallet very securely:

(I lifted a photo from the web because I forgot to take one...it looked exactly like this).

Here are photos of how it was packed in the box:











We moved all of the pieces to the basement and began to build it there to reduce the distance that we would have to carry it. Fully assembled, this dude weighs about 275 lbs. Here are hte pieces ready for assembly:

You know you are on the right track when your sub needs a forklift.wink.gif
post #1581 of 1625
And here I thought I was going to see it assembled - what a tease!

Seriously - looks like a very nice kit.
I will be following along.

The Danley build is rather straightforward. All of the parts are precut, with dados and all the parts are labeled very well. Within a few hours, I had the majority of the sub assembled:





The build required a lot of glue. I used a tube and a half of PL adhesive (the large tubes).

The instructions did not say when the drivers should be installed, so I installed them right before I put the top of the cabinet together.




I ran into an issue where the top would not fit properly. I worked with it for an hour or so and finally determined that it looked as though one baffle was off a bit. The next day I picked up some lipstick at the store to mark the edge of the baffle to confirm that it was truly out of alignment. The lipstick told the story...the suspect baffle was off by over 1/4".





I got out my router and widened the dado a bit, then glued and screwed the top on.


The instructions said it was critical to make the unit as airtight as possible. I installed the speaker connection plate and caulked around it.

Here are some photos of the sub assembled:



I painted the inside of the output grill and part of the inside of the sub. I was concerned that I would be able to see that bright patch through the AT screen. I will paint the rest of the sub black this evening and then cover the front with OC703.

Back of the sub. There are two access panels on either side of the drivers (lower side) and two options for the output throat. There is a grill that covers the output throat.


This dude is HUGE. The sub measures 60" tall, 44" wide and 16" deep. at 285 lbs, I'm really starting to get concerned about how I'm going to get it installed behind my screen wall.



After getting the unit installed, I'll need to learn all about tuning the sound in the room. There's a lot to learn, REW, calibrated mic, Feedback Destroyers, equilizations, etc.

That thing looks......................AWESOME!!!!!!
Good Luck in tackling the tuning!! Keep us updated as usual.

You and Cathan had better not play the same disk at the same time!

Awesome sub. Great work and pics documenting the build.

You'll have to have another get-together to demo.
post #1586 of 1625
He is going to need another get-together to get it behind the screen
post #1587 of 1625
CJ, I put mine on a tarp and dragged the tarp along. Works well on a carpeted floor. Just have someone put a hand up top while you drag to keep it from tipping. From the photos, I can see what althletic potential you have. I also rolled it end over end to get up on the stage. I could roll it most of the way and then drop it the last foot. I put pillows where it would land, but really the pillow is to protect the floor! Would be hard to hurt that sub cabinet. wink.gif

I don't want to get in the way of you Virginia boys having a get together. So, you cannot move it a bit without at least a half dozen qualified home theater experts. tongue.gif Speaking of Virginia boys, I just watched Lawless the other night...some of your relatives CJ?

Tony: Thanks for the tips. I'm going to have noodle this one through a bit. I'll get it back there. I just wish that I had rebuilt the screen wall by now.

I haven't seen Lawless yet, but I'm not a native Virginian. I come from Oklahoma. OK Sooners...the sooner you get there, the sooner you want to leave! smile.gif

Yes there is. I totally forgot to post my experience.

A friend of mine stopped by with a two wheeler to help move the best into place. We removed the screen, then moved the speakers around a bit to make room for the sub. We put the sub on the dolly and wheeled it into the room. A short lift onto the top of the stage, then another lift into it's final home. It wasn't nearly as hard as I had thought it would be. Here's a photo of the sub in place.



I still need to cover it with OC703 and black muslin, then connect it all. I've been very busy, but I know what I need to do to get it connected and working. I'm going to try to get it operational this weekend.
