Derek's Speaker Series/Parallell/Impedance Quandry

[laatsch55]

Wot????
He's been relocated to a residential neighbourhood Downtown?
Didn't he like it in the mountains?
Jeez you Americans do things back to front!!!!

We are between two mountain ranges and when Mama kicks out the previous litter to do the new one sometimes they travel quite a ways finding new territory. Bears wander through here to.

Well, as long as they're being saved, that's the most important thing.
.... but then again, it must be tough trying to find 'em new 'homes', without having to resort to cages.
Either way, it's getting a lot grimmer for them. So sad.

I think it's exposure, or non-exposure I should say.Maybe kids don't take time to go to their buds house and chill and listen to music. When there are no stores to personally visit and sample various components, discovering quality is perhaps more by accident.....

I used to sell electronics at high end retail stores. And from a decade ago till now, (at least the articles I have read recently), today's kids (tweens, teens and twenty something's) seem to be gravitating more and more to the BEATS headphones or comparable $200 headphones or higher. Ear buds are becoming passe'. Sound quality IS developing in desire with the younger generation. But as Joe stated; you are still streaming a compressed signal out of a digital MP3 player. BUT........even that is aggravating a lot of the youth. I have noticed constant desire for loss-less or Master playback on these devices. Coupled with big headphones. Something unheard of ten years ago. But today's technology and mass storage capabilities are now allowing the space needed for these better quality signals. Yes.......the trend may not be the mecca of analog; but at least the trend seems to be going in the right direction again?

As far as Joe's tipping point that's not audio related...........I wonder if his inference is political or societal................

Not yet BD they just went the wong way...

Both...........

 

[Gepetto]

What new tipping point would that be.........not audio related??

Correct Lee, not audio related but also not unrelated to the lofi comment.

 

[Gepetto]

You are kidding right Lee?




Joe, don't know. Had the tunebox on when the paperboy came by the other day. Got the radio on eh? he says, and with an evil grin I invited him in. His mouth hit the floor when he rounded the corner, and was almost speechless when he left. I still think a lot of it is exposure. When you hear a really good system playing excellently engineered source material, a whole new world opens up. I'm doing my part, every youngin that crosses my path we have a sit down in the mancave....

Good Job Lee!

Maybe he will now save his paper route earnings for his first audio component, like we did as kids...

 

[laatsch55]

Ah, low information voters...

Between saving up to buy Jan's old 1982 Honda Accord, and stereo stuff, his paper money is spoken for...

 

[Gepetto]

You nailed it Lee. Good thing we don't mind hijacked threads around these parts

 

[laatsch55]

I think that is the biggest threat to our way of life as we know it. Take the big controversy over fracking. The first frac jobs were in Salt Creek in the late 1800's, and consisted of bottles of Nitroglycerin dropped down the hole. If they made it to bottom without blowing up it did indeed fracture the formation. Sometimes the nitro would not get to location, in the skyline leaseroad the oldtimers said you would see a flash and a big puff of smoke and then no more frac hand or truck. The wells in Salt Creek were only 2,000 feet deep.
There has never been a confirmed case of the process of fracing a well ruining a water zone. The frac fluids are pumped down larger and higher rated tubulars than the normal production strings and are done under a packer that seals off everything above the objective zone. It is not a continous process and is only done during the completion phase. When it's time to actually do the frac job it is a sight to see. 50-75 500BBl frac tanks, 20-30 100 ton sand vessels, 20-30 pump trucks averaging 2500 horsepower apiece, pumping at pressures to 10,000PSI and a buttload of barrels per minute. When they first crack the throttles on all 30 pump trucks, the ground just SHAKES, gives me goosebumples too, just an amazing thing to see, hear, feel, that much harnessed and directed power....It's all over in 1-7 days depending on the size of the frac and how much sand they want to put away. There are some frac jobs in North Dakota that takes 12-14 days to pump, continously24/7. They do not shut down during the pumping of sand and gel unless something goes terribly wrong. They have spare pump trucks that can come on-line in a matter of seconds should they lose one. All pump operators are wired into the control van in real time to receive updates to the frac plan. Depending on how the formation is reacting to the invasion of sand and gel the frac parameters are modified on the fly and pressures and volumes of gel and sand adjusted accordingly. One of the higher tech things that happen out here.....

 

[laatsch55]

The preferred pump motor is a very large V-16 Cummins that is very close to the same size as an EMD, but 2100 RPM instead of 1200.

You know, nobody learns anything new by sitting around doing nothing. Part of our current creativity void is that regulation nation is regulating us into doing nothing. Thus nothing learned.

It is a damn shame that this is happening in the US.

BTW, that would be cool to witness what you described about that much concentrated power in one small area.

 

[pennysdad]

in our day, we had to earn and learn.
today it's all handed to kids on a plate.
no more learning necessary, as the PC put an end to that. all the answers are just there, at your finger tips.
.... and then there's the video games. no need to go outside and explore and play.
.... plus the 'ear buds'. no more staying inside to listen to a good sound system.
.... and let us not forget, the friggin' Mobile friggin' phone. hated 'em when they came out. absolutely despise them now.

I think i was happier when i was a kid growing up on the farm, milking the cows, and bailing the hay, without a clue of wot was to come in the years ahead.
.... and when i first got hooked on music, that speaker box i made out of a cardboard shoebox, to this day, was the best speaker i ever heard!

.... and for f*** sake, someone hurry up and invent a 'time machine'.
I just don't like the future.

... and stop "frac'ing", (although, i'd like to see that too), before you guys split the planet in half. (no disrespect intended Lee)

 

[laatsch55]

Joe, when I was younger I worked in an underground iron mine in Sunrise Wyo. Belonged to CF & I steel corp out of Pueblo, Co. 800 feet down. Gets very dark when the lights go out. We were abl;e to put 60% 2" sticks of Gelodyn in our lunchboxes and take it home. If stored improperly the nitro would drip out of them and you could thusly put a drop on your finger and fling it against a wall and have a very satisfying explosion. The only reason for taking powder home was to blow it up. My favorite was to wait until there was 10-12" pof ice on the local lake , drill a hole and drop a 15 stick punch in the water and run like hell. 15 sticks of 2" x 14" 60% gelodyn is a knarly blast and if dropped beneath the ice in 10 feet of water, the resulting ice cubes have gone very high, making it possible to out run them, if you're fast. If not it's like very large hail.......


Could you imagine doing that today?? You'd be branded a terrorist and locked up for life....We did learn some valuable life lessons, don't transport the box of sticks in the open back of a pickup and get stopped for speeding, DON"t just throw the 15 stick bundle in the water without a good sized rock tied to it, and NEVER< EVER put less than a 15 second fuse in.....

 

[derek92994]

Derek, your WOPL in waiting.....

Its beautiful Lee, I'm drooling once again. How do you adjust the left/right volume on it?

 

[laatsch55]

There is a pot for each channel, hard to see with no knobs. When I do one for me, I eliminate the pots as I see them as an impediment to good sound. I will have to run some pots hrough the AP one day and see just how bad they are...

Well when the time comes, can you please turn them down very low for me before you ship it, you know how crap my speakers are, that amp will kill them if I'm not careful. Will be saving for speakers after I get the WOPL.

 

[derek92994]

Oh one more thing Lee, can you convert it to 240 volts? Otherwise I will just buy a step down transformer.

heh heh heh..... we used to do the same thing when i was a workin' on the railroad.
wot a blast!

You still do, only with your speakers!
