Danley DTS-10 "Super Spud" DIY kit - Page 320

Correct on the ep4000 wiring as others have stated.

For the BFD I keep recommending this page for setup from ThomasW(IB cult). We seem to be re-posting these links but it's ok cause this thread is so large it's hard to find the info you need without knowing what to search for .

(Q is bandwidth)BFD bandwidth setting
PEQ minus 4.6dB, @ 29Hz, (Q=5 BW=0.2881) BFD=17.3
PEQ minus 8.4dB @ 55Hz, (Q=8.9 BW=0.162) BFD=9.7
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

Best to measure before applying anything but these are some frequencies to have a starting point idea of adjusting.


Also those wanting to use a BFD but have trouble finding one can now get the FBQ1000

MKTheater, with due respect, but still the DTS-10 needs a rocket scientist kind of a knowledge base in the sound engineering to caliber and tune the EQ to make it work perfectly.. Not all of us are proficient to do so. Atleast two subs like the seaton or chase work out of the box with basic calibration using MultEQ XT32.
I have been put off many times by not going the DTS-10 route due to the EQ'ing process using the BDF, miniDSP etc. I guess a lot of members in here who are owning a DTS-10 still havent been able to properly EQ the sub.

i think everyone with a dts-10 has probably eq'd their sub properly by now. everyone bought it knowing what was needed to get this working properly.

^^^

Would I be so bold to say that anyone who just plops a sub into a room with no regard to placement, and uses zero EQ (Audessey not included), is not getting even close to the full potential out of their sub. I don't care whether it's the DTS, SVS, Rythmik, etc. For one to truly realize the potential of any sub, they must first understand the room it is placed in; and then how room placement and eq effect performance.

To say a Seaton or Chase work out of the box is not really an accurate statement. The work no better or worse than the DTS, with regards to the environment in which they are placed in.

Where am I? Looks at the top of the page to confirm...Oh wait that's right I'm in the DIY section. I guess it's building rockets for some. If you have a significant other it can be worse. The example of Chase HT isn't a drop in either. The dayton 1000 amp has ability to eq even if primitive it's useful. If your reading anything in this part of the forums you'll know eq is everywhere and part of the game. Yes the Danley looks more difficult at first because you start with having "peaks" inherent to the box design of a TH. Reality it makes no difference weather it's a sealed, ported, IB, or horn eq will help match it to your room. Placement first, eq second. Plenty of tutorial and help in this forum. I'd be willing to bet you could just get a few REW sweeps, post for help, email the file, and quite a few would actually have fun trying to help you adjust and get it where you wanted.

Welcome to the DIY section.

I had a buddy get a Submerssive and it certainly did not work out well out of the box or with "minimal eq". He ended up going to the same lengths that I did with the DTS. I haven't heard his since EQ, I've got to get over there.

Exactly, the DTS is no more difficult to EQ than any other sub. I don't care what the specs say for anechoic measurements, they ALL need to be room corrected to get the best sounding system.

Only if your room has no walls and no ceiling.

No kidding.

Take those two "perfect" subs and add a microphone at the listening position and you will quickly realize how ridiculous that statement is. You can't escape the influence of boundaries and physics no matter how much you spend or what brand you buy or what alignment is used.

The factory peaks in the DTS don't exist IN my room. Therefore, it is really easy for me to EQ it.

The only reason the DTS-10 is difficult to EQ for some is because it is very large and hard to place in the best spot for a smooth response. Smaller sealed or smaller vented subs can be plaved in better locations so need less EQ. The DTS-10 is the real deal but massive.

That is a true enough. Placement can be an issue with a large and 300lb enclosure.

But, there is a price for everything.
Edited by jpmst3 - 1/28/13 at 8:17am

So, I am reading about DTS and it makes me think wouldn't someone be better off building 4 THT's? It should be about the same price.

I think the THT is more difficult to place, as no single dimension is small. It also doesn't dig as deep. But I've heard a pair, and they are quite impressive!

Yes, and no. You will then have to deal with trying to find homes for 4 separate enclosures and the related wiring and as tony mentioned 4 of them will probably still not equal the THT in the subsonic freqs.

You should get a smoother response curve as opposed to one of any other sub.

It's only 225 lbs! Don't make my beautiful girl any fatter than she already is!

Apologies for my ignorant question, but still that perfect subsonic frequency requires a lot of eq'ing.. right? Although the THT still requires EQ'ing, but its still mananages to pull an impressive feat with minimum efforts (barring placement ect). I am more inclined towards the technical aspect of eq'ing of various subs, as they involve multiple components, and a knowledge base of MKTheater or Ricci, only then you can boast of acheiving the deepest possible frequency. On paper THT does not dig deep as deep as DTS, and i am sure it might matter to a lot of audiophiles, but understanding the kind of knowledge they have in this field makes it achievable for them to use various components, maths, calculations and i guess tons of experience makes them make the most of DTS. However people with moderate or above moderate knowledge are able to get the best from THT with minimum efforts, still reaching deep enough that leaves its impact with hard hitting bass.

She is a heavy girl. I've not weighed one but Danley spec page says shes 285 lbs Gents. So our 2 stacked on each other is 570 lbs creating a near 8ft wall sub counting the height on it's very heavy duty castors. But at only 16 inches deep the floor footprint really isn't much.

If I were home more listening to them instead of downrange...I wouldn't be bench racing with REW and forums. Fact is I have 2 and can't see anything yet short of attempting an IB with 6-8 IB318's just to see how it would sound different vs SPL. Not sure if I'd even notice any difference. With two dts-10s the 130dB's becomes reality and how much are you visiting that? It is fun at times I'll admit but a whole movie will leave you exhausted . Nothing exceeds like excess, but I like my house and want to keep from repairing ceiling drywall, replacing floor tile, or that crazy feeling of falling into my garage from our living room.

Far as digging deep, sure. Last time I even ran a sweep with REW at the seating position was rolling off at 9Hz. I plan to induce a HPF at 11Hz to keep from bottoming the drivers at full juice on certain movie content. Lately though it's not been a problem at all without one. Really depends on content and some untested or pre screened showings it can happen. I'd imagine running a IB at full tilt without a HPF is a no go and going to end in damaged drivers in single digit content. Most I've read don't run that hard or have HPF in place at around 10Hz.

Hey guys,
Just wanted to inform anyone interested that I have a couple of dts-10 kits for sale in the classified section. that's it!!! :-) thanks

Brandon, you stated that very well. It's the same feeling I have. The DTS has killed my curiousity. It really doesn't matter what's better, as neither my house or my head could take any more. I could grow old with my current system and know that I'm not missing out. I may, one day, experiment with my mains just so I can keep the hobby going...but I'll buy the new mains without selling my LaScalas. That way, it'll be easy enough to undo my mistake.

I am not sure about yours, but mine tips the scales at about 290lbs, I round up to 300.

No apologies!

But, I think you are getting confused somewhere along the line. ANY sub will require EQing when placed in a room, that is if you want to get the most out of it.
You can always choose not to do it and just live with what you have. No matter what sub you buy and how much you spend on it, once you add it to your room the freq response will be modified, most times significantly.
My THT required the same degree of EQing that my DTS now does. I discovered long ago that the best way to tackle most of it was to add more subs to even out the response. The DTS is a sub, plain and simple. They all behave the same when placed in your room...You will peaks and nulls due to interactions with the room. The same principle exists in a microwave. Put a piece of frozen meat in there and put it on high for 10 minutes. There will be some parts of the meat that are cooked to death and other parts still frozen. There are your peaks and nulls due to the rectangular box and the interactions from the waves within. Of course, turntables were added to help alleviate the effect somewhat, but it still remains.
I am not sure why you are hung up on the process with the DTS. Drop it in your room, measure, apply EQ. It is the exact same process as ANY other sub. If you don't want to EQ ANY sub you will most likely have much less than optimal bass. Like anything else, if you don't know any better and/or don't have anything to compare the raw response to the EQed response you will think it is just fine. It is no different than viewing your 7 year old HDTV and then going over to your buddies' place and seeing his new TV. You thought yours was just fine until you saw the dramatic difference. EQing can make a dramatic difference as well. You can tackle that with a number of devices that are reasonably easy to use, ala miniDSP, DCX2496, etc. or buy a sub with an EQ built in, like Velodyne or ?
Somehow, perhaps by reading posts by those new to the hobby you extrapolated that the DTS is some uber special case for EQing. Yes, there are a couple of peaks that are inherent in the design. There are also peaks in the the THT's response. You can choose to tame those before you do anything or you can choose to EQ the final in room response.
Once again, even if there were some magical, mythical subwoofer that had a perfectly flat response, that all goes to hell when you add it to your room....bring on the EQ!

Hi All - Since this thread has become more active, I thought I'd note that I recently found what I think is a good deal on an EQ option for this speaker. It is the new version of the BFD, model FBQ1000 (appears to be a replacement for the DSP1124P).

The going rate is $149 at music stores and online, but i found www.uniquesquared.com. It is an authorized dealer per the Behringer website and is selling the unit for $109 with no tax and free shipping. But they also allow you to make them an offer...I offered $95 and my offer was accepted very quickly (maybe I should've been more agressive). I know there are still some DSP1124P's to be had on craigslist etc. but if you're looking for something new I thought I'd pass this along.

I have had a DTS for quite a while, but forced myself to wait to get into EQ until my HT construction was finished. Really looking forward to it! (and also probably to some help from you all )
Edited by AirBenji - 1/29/13 at 6:48am

I am not familiar with that model, but that sounds like a good deal.

It's a rebadged 1124P basically the same thing. There's a thread going at HTS and apparently it also communicates over midi the same setting as the 1124p. I posted the PE link above but the Behringer direct sounds like the way to go.

Nice, if it works, it is a cheap solution.

OK, as requested here are videos of a brief Cloverfield sequence taken with my cell phone camera, through the new acrylic access panel I recently made. (as you can see by the reflections)

The first video is the excursion:
Please note: I have two other sealed 18" LMS-5400s (endtables) in the mix so the DTS-10 is not the only sub in the system. I am using one channel on a CE4000 (4ohm, ~1200w) for the DTS-10. The DTS is directly behind the couch at one listening position. The video shakes a little due to the strong tactile sensations on top of the couch (where I had my arm resting), since the mouth of the DTS is directly below. The shaking is in the camera, not the acrylic flexing or the enclosure shaking.

I firmly believe in under utilizing all components in the system so the DTS definitely has a lot more in the tank with both power handling and excursion. The amp (channel) would probably clip if it were few db louder. Of course, I could not listen at those levels for more than a few seconds, ouch! In fact, my head is pounding from that short sequence.
Sorry the excursion is not all that impressive. But, it is damn loud in the room, especially right next to the sub. It is just interesting to see it for a change. I am really liking the acrylic panel.

The second video shows the Radio Shack SPL meter during the beginning of the same sequence. The meter is set to slow, C weighting, 120db.
I am not sure why I could not get the meter to hold the max SPL. It definitely hit at least 123db frequently.

Notice how the white foam yellowed too.

Man, what has happened to the DTS love?
I assume people are still buying these beasts!
No questions, no comments, where is everyone?

The tapped horn fad has kind of worn off around here, it seems. A well designed one is still a worthy candidate to be put in a HT but I think the multi-sealed systems are the IN thing at the moment. I think the draw is the massive simplicity (notice all the new peeps around and ID converts? ) and full bandwidth extension.

Say What!?!?!?
That's blasphemy! Long live the tapped horn king!
