Danley DTS-10 "Super Spud" DIY kit - Page 313

Bill Fitzmaurice (think he's a member here) who is the developer of the 'Tuba Sub' has some interesting info here http://billfitzmaurice.info/forum/viewtopic.php?t=398 on sub locations.

He mentions that locating by a wall gains 6 db and in a corner 12 db. He also says "In most cases you'll have best results aiming the subs towards the wall or corner with the mouth about a foot away from the boundary, using the room corner as an extension of the horn as shown here" (illustration at linked page).

Another very interesting tidbit (Bill I sure hope you don't mind my quoting you here!): If there is a 'prime directive' when it comes to sub placement it is this: Never place subs with their radiating planes between 2.5 feet and 8 feet of a boundary.If you do at some frequency the within the 35 to 100 Hz passband, depending on the distance, the reflected wave will be 180 degrees out of phase when it meets the original wave again, cancelling it out. He then gives a link to a very helpful chart on boundary cancellation and room modes. http://www.padrick.net/LiveSound/CancellationMode.htm

Lots of new information for me - I'm going to soon do some experimenting.

For those of you who have aimed your sub at a wall or at the corner, have you had any issues with wallboard rattling?

Thanks,
Rod

Duh...... and why the walls of the living room extension [video/sound wall] are now doubled up 3/4" MDF.

On about the second time I had my DTS10's running (very hot admittedly) I heard a dreadful banging noise during loud passages. I thought I had driven the cone way beyond what it could handle and was not real happy after finally getting my subs set up. Turned it down, no problems. Turned it up again and the noise came back. Walked out of the room, down the hall and realized that it was my metal door knocker banging on my front door. Ooops. now that I have the door hung in my room, that's not an issue anymore. Now it's just the guttering that vibrates. Gotta laugh! I love these subs!

Are the DIY kits still available? If so, how do I order?

Nope. Sorry.

Finished a number of months ago (last year).

I used to rattle my neighbor's gutters!

I never forget the first time I turned on my dual DTS-10s. The rattling china and glasses in the kitchen cabinets and the pressure wave through the wood floor. It was, and is still, awesome!!!

Me neither. I flexed the walls so much that it made a bunch of the sheetrock nails pop loose and put a bunch of small cracks in the corners. Not to mention it pisses off the wife! I love it!

My lady informed she think's she fixed the last rattle in the living room. Suspect was the main picture frame over the couch. It was subtle so took her awhile to find. Extra staples and some wood glue in every seam of the frame made it solid to stop flexing. The back is stuffed with foam. Re-hung all the pictures in the house with some sure lock clip hangers to keep them on the walls.

Now if I can just get home to build and add the second one to see what breaks next. One of the last kits is still sitting in the garage stored away.

Delayed timeline getting home, but looking end of March now.

I haven't made much of an attempt to stop all the noises. It seems hopeless.

Updates and a thread bump.

I found and solved some of my issues with the dts-10, I got back inside and sealed a leak I had in the motorboard, and I am now using a Onkyo 886 for preamp duty. Man this thing is a beast, still far from ideal placement as my theater room is not done yet. I'll tell you what though, watching the new Tron Bluray last night felt like ghosts where stomping up my floor boards, my PJ was on the coffee table maybe 12-13 feet from the DTS and the aerial battle scene had the PJ shaking like an earthquake, amazing stuff.

In 3-4 weeks I should finally be setting up my 2 Danley DTS-10's in the theater room. I have the 2 Danleys's, 2 Behringer EP 4000's, a 2x4 balanced MiniDSP and a Marantz AV7005 pre-amp. I also have 2 additional Atlantic Tech 642e subs that may get used as well. Starting to school myself on set up for these subs.

Couple of questions -

1) Is '2way Advanced' the plugin I need for the MiniDSP?

2) Is there a good summary/tutorial of setting up a DTS 10 (or any sub for that matter) using the miniDSP and REW?

Thanks for help!

Yes the two way advanced is the correct plug in.

I EQ'd mine using Omnimic to measure but then using REW to generate the EQ solution so you can use this thread as a guide.

I did not intend it to be a guide or tutorial but it will help.

I am pretty confident with two DTS-10's you will not need your other subs.

Have fun!

Thanks! Your thread will be a big help getting the process started.

If anyone has ran REW on the mini dsp with dts 10's could you post your settings please? Im wanting to see where you added db to certain freq areas to give more punch. I have 3 dts 10's but never had REW ran and dont know how nor have anyone near me to help. I understand itll be different but I still wanted to check it out.

Found the source of my airleak on one of my DTS-10's. Took 4 hours with a buddy but we got her done! 2 properly DTS-10s in a 1056 cubic foot room is facking nuts

Where was it?

Forin, Glad you found your leak! And, yeah, where was it? Tell us more.

tony did you apply a bump up in db in certain freq areas on your dts 10's?

I run a +2db bump at 20hz. Other than that, the 5 filters from Tom Danley. Depending on source, I'll take out that boost. Usually, for bass heavy movies I pull it out.

What filters ?

After we tore off the entire back panel I noticed that every channel on the back had some wear except for one of them, it still looked pristine. We made sure the drivers were all torqued down and I siliconed the hell out of them just to make sure. Then we did a few passes around the interior to make sure everything was good. After that we put the back back on and bought 1/2 inch longer screws for that channel and really torqued it down. It measures the same as the other one now and the chuffing is gone!

Forin

PEQ minus 8.4dB @ 55Hz, Q=8.9 BW=0.162 BFD=9.7
PEQ minus 4.6dB, @ 29Hz, Q=5 BW=0.2881 BFD=17.3
PEQ minus 7.5dB @ 84Hz, Q=2.8 BW=0.5125 BFD=30.8
PEQ minus 14.4dB @ 154Hz, Q=1.1 BW=1.2701 BFD=76.2

These are directly from Tom Danley. They fix "at the mouth" measurements, and don't account for anything your room is doing. However, my experience, in my room, is that they are a great starting point that transformed the sub in my room anyhow.

Seems we end up reposting these filters every few pages. If you search through the thread, you'll find plenty of discussion regarding them.
