So having noticed there are fewer and fewer actual builds going on lately, probably because of the economy. I know my personal economy is limited so I am not making anything very soon.


Anyway, I thought we could have a weekly or biweekly selection of a movie clip with decent bass and have everyone post their db's with a couple variations than just max levels. I was thinking we could do a nearfield measurement, listening position, at both normal listening levels and max only if you are comfortable with your equipment running max levels. This way everyone has the same clip to go on.

I also think if we have rew we could post our response graphs from near and then at the LP just to show what we are achieving on the extension side.


Be sure to note what type of setup you have. List your subwoofer, amp with power wattage, whether you are using the DVD or blu ray version of the movie, etc.


I know this has been done before, but its been a while since it has been over here on the diy forum and it should be fun and free. As said before, don't do anything with any of your equipment you are not comfortable with. This is not a competition, just a more fun way to know what your and other people's setup can do. Will start in the next post with our first selection and if anyone has requests for the following weeks selection let me know and we will run those picks.

First week's selection is...

CARS Intro

This one is a very good sounding scene with very high levels of bass, but most is concentrated around ~30 hz. It has some lower stuff built in there, but it's mostly stuff that all subs should handle. To boot it's a great movie. I believe this waterfall is from the first minute or so of the movie. I will get the exact point when I get home, but it's the scene when Lightning Mcqueen first gets out of his trailer.

Someone needs to do a Wall-E waterfall. My son's been on a big Wall-E kick. But that might be because we (he) lost Cars somehow.

Need them all on hard disk so you can burn a new copy when necessary or just play them automatically from the Drive

It saves me money, my little girl scratches DVD after DVD.

 

[brandonnash]

I have to do the same thing. I keep the original in its case and make copies for my kids to destroy as we go. Learned that the hard way.

Heh, I have 2TB of available storage. If you know of a good quality program I can use, let me know.

 

[brandonnash]

well I was about to start testing mine, but it got a bit late. Don't want to wake the kids up. Will try to tomorrow in the morning. Have the day off and the wife is running errands. Hello 110 dB!!

DVD Fab platinum, Been using it for several years now. Worth the smallish amount of money to buy the Platinum.


Its great to backup all the movies and its also great to cut versions for the Ipod, PSP, etc.

 

[brandonnash]

Alright, I'll be the first to throw in. I learned that I listen a bit lower than I thought I did, which is good. My hearing is not all the way gone from years of hard car audio and Pantera concerts.


At listening position during this scene I was running around 95 dB at normal listening. When I cranked it several times I walked my way up to 113 dB before the wife stepped in and cut me off. I think it had a little more room to work, but I was about at my limit anyway. I will say that after running up the sound some I need some better mains. I'm just running bookshelves for my mains and they were at their limits probably a couple dB back from where I got to. My sub could've done a little more, but not much. At least I'm able to get reference levels on the peaks.

Penn: I've looked at some other DVD burning software (DVD Clone), but never did use it. This DVDFab looks pretty easy and may be exactly what I need.


I downloaded the trial version, so we'll see how it works out.

Are we all going to be using the Cars scene and is it at listening position?

 

[brandonnash]

I just did listening position and that's what I got using the cars scene.

i'm not sure if this is right. much of the enthusiasm has been around "how crazy can one get?" several builds have gotten there. much of the confusion has passed by. beyond reference has been achieved. high performance has become formulaic. that takes some of the fun out of it, but that's just reality. thirsty, turn on the tap. in darkness, turn on a lamp. without bass, quad maelstroms, 2 ep2500's (maybe 4), some eq, done!


not many boards on water or lamps for a reason. i think the same is going to happen for bass. problem solved; go home. have you noticed, most all the discussion resolves around the unsolved problems?


nobody debates whether the sun revolves around the earth or vice versa, though that would have been a hot topic several hundred years ago. ;-)


in some sad way, achieving the goal kills the quest; and isn't the quest at least as much fun as the goal?


does our pursuit strive to end our meaning? lol. chew on that one.

 

[robertcharles]

Listening position is 126.1. This is with 1 crown Itech 8000 in stereo at 8 ohms with both LMS cabinets playing. I do not know how much is left with the 1 amp, but the kids are wound up and I am now watching another movie. Will get to more measurements later.


Thanks,


Robert

Deep, but if it were just spl we were looking for then we could buy a have dozen or so 18's and be done with it. There's always a lot more to it, quality bass, headroom, extension and so on. I don't think it's just an easy solution and I think as a whole we're all looking to try to achieve the ultimate in listening potential. Do you think that we'll stop making subwoofers or speakers just because we've reached a goal? Goals change or become outdated. I'm sure once the new LMS drivers come out there will be huge talk about them and how much better sounding they are. Speaker drivers get better, new alignments are discovered, newer technologies. All this and we have budgets. I'd love to have 4 Maelstroms, but my salary won't permit me to have something like that. I'd love to have Robert's setup, but I'm sure there are still ways that you could improve over almost any setup. Until we can get ultra clean sound that reaches down to 1 hz at crazy levels from a 1 cubic foot box for just a couple hundred dollars we're all going to be chasing that, all with compromises along the way.
