Agreed here as well. I don't know what type of additional extension you would want, as you'll be giving up to goods above 25hz or so, and that's what's so special about them. Just roll with a Large ported if you want to get to 15hz for HT. I've been running mine now with one port plugged for quite some time now and it handles music excellently... all of it.

Hey Beast.  Good to see ya again.

I agree it looks like a decent track.  It might get better with BEQ.  Do you have BEQ capability?  So far my favorite bass movies are actually movies that were filtered and then corrected with BEQ.  I just watched GOTG2 With BEQ again, and Wow!  Just tremendous.

Hey buddeh! Unfortunately I don't have the capability for BEQ. I have to agree with you tho, Max brought over his demo disc of BEQ'd stuff when I had my last g2g and it was unbelievable the difference that BEQ can make. Just astounding.

Lol, I have outlived my usefulness on these audio boards. I'm just here to have a good time.

Oh, come off it. AVS is a deep dark place without you present to joke around and poke fun of things with me...

-10dB point is ~15Hz on the Avg. Not great but not that bad. Just looks worse than it is with lots of peak energy in the 30's which is typical.

To be noted, it looks to be (and is) a very dynamic track with very little clipping of which is only in the LFE channel. Also a first rate immersive/surround mix.

 

Yes yaassssss, That 16hz still about to tickle the -15. The 30hz at -7.5?!?! That is some serious stuff right there. Im ALL about this when I go to buy it next Tuesday...

We gotta new record:

Would you look at that beaut! 5 star extension right there.

An 18" behind your couch?  That's a joke compared to what two Skhorn's will do.  IIRC, @Beastaudio is running *one* Skhorn these with together with 8 x 18s to handle the ULF.  If you are using these for home theater, you could probably just plug  a port or two for more extension.  If you make them easy enough to remove, you could even switch back and forth depending on content.

Naw. Only 6 18's with two of them being HST-18's nearfield to keep up.

They may end up being used for theater, but probably not very often. Primarily I'm just after pretty damn loud with low distortion. To date, the only subwoofer I've built that impressed me were the lab12 ths I built. Been building and chasing for about 20 years and I've mostly stuck to simple vented cabs, but the th is happier playing up at levels I find fun, so rather than build yet another vented cab that'll get me into the 120s sweating bullets, these are more likely to get me grinning. If I end up missing that bottom end, I'll start ordering 24s for next year's fun time.

 Swapping the plug in and out was one of the things that caught my attention when I started looking at this. Do I want dubstep mode or metal mode? Hmmm...

You are correct though, I'm sure the output will far outpace what a single sealed 18 would do, even at 1 foot from mlp distance. I'll come up with something, eventually. If I even miss it.

Really freaking loud with low distortion and a side of Rocky Balboa TUFF is exactly what this cab is about.

This wasn't really made for being in a domestic space nor for use with only 1 vent per side open. That said IF it is used in a house the gradual roll off of having only 1 vent open might work quite well with room gain. I wouldn't be surprised if there is still more output than needed and managed to get down to 15 or 16Hz. Even with only 1 vent per side open it still has the equivalent of 2 5.25" ports or one 7.5" port. Personally I'd start with the 2 vent mode if using one in a home but I'd definitely try them all and see what works best. I just can't see using all of the output from normal 30Hz tuned / all vents open in anybodies home, so using the lower tunings seems like it should be worthwhile. 

Brandon or Ti,

Did either of you play around with blocking the vents?

I made a "two vent block" the same time I made the one vent block but have never tested it out either. I know with one vent plugged I can get dead flat extension to 20hz as anticipated. No need for any shelf or anything. The rolloff profile seems to fit perfect for that. I keep meaning to mess around with the 2 ports closed mode but end up just tweaking what I have to get it ever more dialed in. switching the plugs out would toss all that out the window. Many cold months ahead however, so I will be spending much more time tinkering. 

That's not how it works with a design like this. You gotta hornresp all of that to see how it shakes out.

Oh really? Well then... Looks like I won't have to drag one with me next time you have a GTG then. Works for me.

"Get one of these bad boys going pronto" has a direct translation to "Dangit Josh, hurry up and get tired of your skhorn and just bring it to me"

Testing season aka the ground isn't frozen solid?  

I sell some stuff, I will be wanting to get one of these bad boys going pronto...

Hmmm...That cannot be right on the version I listened to. Lowest note seemed to be lower in volume but is way below 28Hz or I'm losing my judgment. I'll see if I can run the version off of Spotify that I heard.

Or there are different versions out there, maybe?  I'm pretty sure what I heard didn't go lower than 28 Hz, and it was pretty weak at that.  I'm still at a loss for why the track had so much wasted headroom.  Maybe all the bass was EQed way down for the YouTube version?

I can't help but think this is the case Sergio. I have the song locally on my library at home, and have compared it to the Spotify version and they are basically spot-on. This is one of my main bass go-to demo tracks for folks who don't mind the vulgarity at least. The lowest note that IIRC from it being spec'd showed 17hz-19hz I am pretty sure. 

Huh? It was just a one-octave smoothed graph illustrating a comparison to the "preferred" FR shape Max was commenting about.

 

Of course the full un-smoothed response does not look like that.

Oh I know that, but the overall slope of the graph is what I basically consider perfectly balanced, and aim to hit anytime I am messing around. Send me the file, I just want to see exactly how close we actually are! Or don't, I'm not the boss of you. 

One octave smoothed graph of my main FR.

 

God Almighty... an image of perfection ladies and gents. Send me that OM file, I wanna see how close I stack up. You still have my email address

Completely O/T, where is Japandave?

 

I've not been on AVS for ages so I don't know if he's still around?

I haven't seen him post on avs for some time either...but, I kinda just stick to threads that friends open or are pretty long in the tooth and relatively drama-free...

Not from what I have heard. After STID, that means we can't put SOLO judgment on JJ Abrams for being the deciding factor here

Man, don't bring me down on a Fri like that.  It's just not cool.

Plus, I know it's not this sites measurements, but the chart for STiD looks a lot different then the chart for this movie.  I mean, STiD just drops of a cliff where this looks like a much more gradual decline.  I will take anything down to 16-15hz with hints of content below that because my Crowson will pick up those parts,  I just hope it's not a loudness fest.

What I meant was that the presentation was clean according to a few sources. LOUD, but clean. I can stomach some clipping, and even feel that even sometimes it is almost used intentionally, but we see it as a mistake around here. Sorry reading back I can see how you took that wrong way. From all accounts the video is just as good as the audio btw too. 

First, that initial chart looks good to me.  I am looking forward to seeing the numbers on this site.

Second, I appreciate what you're saying here  .

Now I just hope that the measurements show that it does not have insane clipping.  But from feedback, it seems that it does not.

*Groan*

Oh cmon!

Since this mix seems to be so nice, perhaps the next two movies will just be a few Leia-ups for the sound crew. 

If that graph is right then maybe there's hope. 

A new hope? 

See what I did there? Star Wars jokes are my favorite.

I am glad this one looks so promising though, and from those I know that have heard the home mix (lucky buggers), they said it's nothing short of fantastic. A breath of fresh air. We won't be uttering "I find your lack of bass disturbing" while watching this flick. Sorry.....I couldn't help myself....

Sergio posted TFA over on avs. Looks promising:

Little rolloff, but seemingly good extension still. 

Cool.  Should liven up the discussion around here.  Seems kinda quiet lately.

No kidding. But Snoop nailed it, there can't be much discussion when there is no new content to talk about...

I think infrasound is a rather unexplored area that deserves more attention - even back in ancient times, I believe that it was used to elicit an unusual physiological response:

OH boy!!! If you liked that one, try out this one!  Tested by one of our very own!

I hadn't read those threads yet.  Thanks!  I get the impression that bass addict wasn't so much dissatisfied with the 2 X TD6  speakers he built for "heights" as he was dissatisfied with the overall result, particularly the TD-15M + SEOS-12 + BMS-4550 builds he did.  I can try to guess at what he might of done wrong, but it's largely speculation without some good measurement data.

 

Another important point is that the design uses TD6M drivers.  I don't know why anyone would try to use TD6Ms as woofer because they really are mid-range drivers.  Notes from mtg90 on the DIYSG forum indicated that the mid-range was brought way down to deal with the bass roll-off resulting in a sensitivity around 92 dB/2.83V and 4 ohm impedance.  That's worse than what I have now.  For my design, I planned to use TD6Hs instead.  They have a lot more excursion capability as well as more mass and motor strength for use as actual woofers.

 

I sit about 3 m away.  You would be correct to say that my build is a bit overkill for reference level playback.  But that hardly puts me in strange company around here.    I want something that'll keep up with my mains and deliver excellent sound quality.  The TD6H pair with help from the corner can probably do about 3 dB less than my TD12M mains.  I know it's typically argued that surrounds need not be as big, but I do want a lot of headroom.  For one thing, I'll be sticking to 5 mains channels in this room, so the surrounds will have to handle sides and rears on 7.1 tracks.  For another, Atmos tracks and tracks originating from Atmos theatrical mixes have a lot more bass in the surrounds because of the surround bass management that theatrical playback systems added for Atmos.  Third, I want to use the surrounds to help with room EQ, even for sounds that originate in the mains speakers.  As such, I really wish I could make a pair of 8s work, but that causes too many other issues in the design.

 

 

Thanks a lot to you, Ricci, and 3ll3d00d for your suggestion.  If I decide to go with a coax, I'll definitely lean heavily in that direction.  I do wish they made a 4 ohm version so I could get a bit more power into them.  Both this and the Eminence have sensitivity of 95 dBish.  I expect a TD6H pair to yield 97 dB.  Of course, the Radian probably has a bit more bass if I end up needing it, but I can't find an Xmax number for it.  Can anyone help?  The other reservation I have is that I'm pretty sure I want the tighter horizontal dispersion of the SEOS-15 horn turn on its side.  I'm fairly certain it will help a lot with front wall reflections I have.  I know because I've done a lot of acoustic measurements already with speakers that are already installed in the planned location.

Lemme know on the radian if you decide to go that route. I can supply an XO schematic if you want to do that...or you can roll your own

Bro...They can't all be Roy Rogers films.

I don't know who that is...

Or Gene Autry!

I have to admit, it is nice now waking up to that silky smooth voice everyday. I have that disc on a timer to go off in the mornings. Sweet, good ole' country tunes to wake you from your slumber. 

Oh, you will be disappointed.  Words cannot describe the letdown of the first Hobbit movie.  Not only is the soundtrack beyond lame, the movie is really frickin long considering not much happens in it.

Wow, perhaps one day when there are no more movies out there to watch, and I just want to be a stinky mood, I will watch it.

 Guess I'm no one. I was interested in the Hobbit movies. I dug the LOTR trilogy movies and thought the sound work was good. Read all the books as a kid.  I'd say a gigantic fire breathing dragon should have had a bit of low end as well. It's not like that wasn't a very big movie as well. It had plenty of backing. There was like no bass at all...Or damn near. Not even a loud 40Hz rumble rehashed 50x in a row. Avengers at least had some bass. Generic action movie bass to be sure but at least it wasn't MIA completely.

Is it odd that having never watched any of the most recent 3 hobbit movies. I mean, not even a second of any of them, that I am slightly interested to watch at least the first one just to see how big of a letdown it really is? I guess I won't even turn my subs on. 

The Mrs & I screened Everest tonight. Lots of rumble throughout, but next to nothing <30 Hz. When the largest rock formation on planet earth lets loose a few mega tons of glacial ice and rock, I guess there's no ULF to experience.

 

I just hope I never get to find out. Climb this, you complete maniacs who pay a small fortune to climb Everest "because it's there".

 

Great story and film. Frenetic and emotional. ULF would have cemented it's place in history. Bummer.

Like he said, "Humans aren't supposed to survive at the cruising altitude of a 747." This movie shook me to the core. Not only did I feel cold basically the whole second half, but I was emotionally connected to the characters, knowing that they were portraying REAL actual human beings that made that trek.  I even had some unsettling dreams that night after watching it. Few movies have ever done that to me.

I'm with you though. $65k is a pretty expensive unexpected funeral for many that go up that hill. Not for me bro, no way. If a chairlift or helicopter can't take me to the top and I can ride my snowboard back down it, then it ain't happenin' 

I'd go no lower than 8cuft (also slightly depends on split-coil or overhung version) but I'd shoot for 10-12cuft at the least.

Hey Ricci, you mentioned the xxx would perform better in a larger sealed.  What size did you have in mind?  I'm helping out a friend with a nearfield sub and am hoping to use one of these little fellas you have here.  

The overhung version has quite a lot more motor force than the split coil so it works in a smaller box. It doesn't model like the split coil version. 6 to 8 cubes should be just fine.

That's really good to know. I was dumping all a sanway clone could give to my pair of split coils in 8 cuft boxes and they just laughed at it and kept asking for more. It's good to see they remedied that somewhat with the overhung design. 

Oh, and so when are we  going to compile and vote on "Bass movie of 2015?"
