i have insomnia and i'm bored which makes me deadly silly. so i took the drivers from my dls iridium 6.2s and swapped them with mid/high of mission m35i loudspeakers. you can definitly tell the iridiums need to be broken in since they sound only half as healthy as original mission drivers. but i see definite improvement in clarity. but impressed am i? not really. putting $500 drivers into $500 speakers have got me wondering 'was all that nessecary?' errr thats about it. i just wanted to tell my tale.
errr what about MY experiment? do you guys think perhaps the speaker's soundfield range is screwed up now since iridium car speakers were designed to be listened up close?
EJ, what possessed you to change out the drivers? Did you do any research into the electrical and mechanical parameters of the speakers you replaced and substituted? Or did you just have a big plate of MooGooGiaPan and the MSG kicked in?
What Jan is talking about is the fact that the mission drivers, although cheap, were meant to be in that enclousure, to work with that crossover and that tweeter. For the desired response and range that is possible with that enclosure.
Now if you found out the parameters of the drivers, used a box program to figure out the response projection and then modified the crossover to fit both the new driver and the original cross over that would work better.
yeah i swapped them back about an hour later i changed them. and after a good nights sleep and some coffee in my belly, i think it was a pretty dumb idea. god bless caffeine
Jan each driver in the cabinet, tweeter, mid and woof all have an effect on the response.
Say he put the speakers in, not using the crossover that came with the dls's, the drivers would be fighting the crossover as it was not designed for them. Second there would be a chamber into witch the mid driver would be firing and that would have an effect on the response of the T/S parameters of this driver. The design looks like a two chamber affair with a 3way crossover. If you replaced the tweet, mid and the crossover with the dls and then placed that in series with the original crossover with the bass drivers still attached you would have a better idea of how the drivers would actually sound as you would take the mission xo out of the equation for the high/mid put in would still be affecting the impendence of the speakers as it is still being used.
Try that it might sound better? Only a possibility.
yes, i just got done doing that and it sounds just like how it should- $500 drivers in a $500 speaker cabinet. but if i'm to answer if it's better or not, i'm not sure if i can give a clear answer right now. first of all, i think there might be a play for ear fatique. i'm not sure tho since it's 3a.m. already and i'm beginning my first stage of insomnia. i mean my whole body's tired... second thing is, it just doesn't sound 'right'. dls are way too bright compared to the characteristics of the sub. but if the imaging and crystal clarity of this sound is persistant when installed in the car, i think i have a winner on my hands. and yeah, i'm gonna keep them in for a week or two just for the sake of breaking them in. any idea on how long dls takes to break?
Well, for what it's worth, I think this is what Hi-Fi is for. It's just like a chemistry set, only with sound instead of the ability to make hideous smells.
Why not experiment? Even the dumbest idea may teach us something useful in the end.
Why not experiment? I would suggest that you shouldn't experiment if you don't have a clue as to what you're doing. While this bit of trial and error isn't what I would call dangerous, when you begin to fiddle with 120Volt lines and 15 amps of current, you really should have an idea where not to stick your hands or screwdriver. Or, at the very least, a very good friend standing close by with a two by four.
I don't recall having ever encountered 120Volts within a speaker line, Jan. Having said that, you never forget your first shock... That surely teaches one something? I found it very enlightening... and we in the UK have a bit more juice running through our domestics than the US, I believe. Ouch!
Reading comprehension is not high on many members skills; is it?
Sir, if you have 120Volts AC and 15 amps running through your speakers, it will only be for a short time (no pun intended). Though woofers connected directly to a 60Hz line will make fascinating noises for about ten seconds.
And, it is not the first shock I am concerned with, it is the last.
i understand your concern but don't think i can sympathize with it. it's not rocket science or rigging up a bomb we're talking about here on this forum. since 120v is all the risk there is to be concerned, i figure it can't be that much more dangerous than changing a light bulb. i never heard of anybody stupid enough to get shocked while changing a light bulb (at least not in my gene pool) and nobody clueless and still fiddled with $1000 equipments. i had plenty of that (clues) and i succeeded in my experiement. and since i was able to prevent myself from the 'first shock', i don't think i need be fearful of the 'last shock'.
Eric, the driver sensitivity is not the same between the bass drivers and the m/h combo. You will need to put some value of resistor or network in there to accommodate for this. This can be done with an L-pad type variable resistor. This is the part that Tim mentioned "If you don't measure, you don't know." because most lik likely the m/h combo is not actually "brighter" but the way the 3way xo is working and then the other 2way xo is working.
Try that out, it might work. But to truly understand you will need to do some measuring to find out if there are any differences in impedance and sensitivity and response.
PG - Oh, that's a good one! Oh, so smart of you! Oh, how did you get to be so bright and intelligent and all that wonderful, adult stuff? You obviously can't read either!!! You know, PG, if you're going to start following me around the forum trying to make me look bad, you shouldn't make yourself look like a fool in the process. What made you stick your nose in here? I thought you were being a grown-up adult and ignoring me as best you could? How grown-up is that?
"While this bit of trial and error isn't what I would call dangerous, when you begin to fiddle with 120Volt lines and 15 amps of current, you really should have an idea where not to stick your hands or screwdriver."
Commas really mess with you guys; don't they?
"Though woofers connected directly to a 60Hz line will make fascinating noises for about ten seconds."
"I can tell, you've tried this out haven't you? How reckless of you, Jan."
Not I, sir. The techs I worked with ocassionally needed to have a warranty repair when someone else did something stupid. The hardest to destroy were the KLH 6 woofers.
yeah and his tantrum is taking all the attention away from me. over here guys LOOK AT ME ME ME! cuz guess what i'm gonna do next- i'll rewire the iridiums to my dls amp and have the input come from the home receiver... how should i power the amp tho? i'm thinking 12v power adaptor?
PG - From what I see, just being allowed to use a computer should be impressive to you. How often do the doctors let you do that, PG? It runs on 120Volts, PG. OOOOOHHH, scary stuff, PG. Do they know you're doing it now? They're coming for you, PG. They're coming!!!
Why can't you read, PG? What's your problem with plain English? Did you ignore your English teacher too? Did she make you feel bad about yourself, PG? Do you dream about her also?
I've tried to make up to you. I've told you I think you're smart. I even meant it. But, you hate me so. How grown up is it to bear a grudge like you do? Not very. But you knew that; didn't you? Do you tell your analyst about your grudges, PG? Does your analyst make you feel bad about your grudges, PG?
You are a goof!
And, you're not much fun. Why come here if you don't want to have fun? Oh, yeah, you're ignoring me. I forgot.
My English teacher was what one might commonly refer to as a 'babe'. Science teacher was the best though, since from my low vantage point, I was able to see right up her skirt. Hooray for physics!
Just thought I'd share.
Damn! You've set me off on a revelry about childhood now. Talking of which...
Jeez, I wonder who really needs the psycho help here. We're getting touchy, aren't we?
I can read english just fine, thanks, even if it isn't my first language. You said it yourself, While this bit of trial and error isn't what I would call dangerous, so why bring up 120V and 15 amps in the first place, apart from being your usual rude and sarcastic self?
BTW, following you around the forum should entain more than one thread, or are you that paranoid about me.
LOL! I really got under your skin, didn't I? That's great! Makes my day.
Might well be a semicolon I need, Anubis. Though I don't know that that would make a difference in some cases. Commas and semicolons are still a frequent decision with me. Six of one, half a dozen of the other. I can't tell stories of looking up my English teacher's skirts since I had nuns teaching me. I'd have had to get pretty low to the floor to look up one of the nun's habits. And, all I would have seen would have been more petticoats. Though your story sounds like something an analyst might enjoy knowing. Sister Marie James was more interested that we know Chaucer than commas. Unfortunately, that is the first time I've mentioned Chaucer in twenty years. I could use that comma stuff much more frequently.
Oh, my! I'm sure to have left an opening for PG to enter with that last comment! He sees such failings as personality faults, you know.
"Commas and semicolons are still a frequent decision with me."
Although the English Language has a set of rules, I think recognising it's organic nature may often be the key to creativity with it!!!??///*.;
"Sister Marie James was more interested that we know Chaucer than commas."
Then I think she served you well, since at times, Chaucer provides the coarse roughage so essential in any young boy's literary diet. My own education was not so refined... I had to make do with Carry On Films.
In places, this thread is getting somewhat ugly in it's regressive qualities. I think it time to visualise the female teacher's (c)rotch as a distraction from this war of intellectual vanities.
Our failings are like trenches. If we can say that we fought in them to emerge with better tactics, then we should sport such medals with pride.
Wow! I get up early to write this crap. Fancy that!
Probably only until I start at the embalming school. Until then, I'm getting the house comfortable for evenings spent in, doing my homework. That includes the audio systems. One more thing not to think about.
But yeah, I'll still be in here periodically. Why not, eh.
And you think the embalming school line is gonna slip by that easily, V, er A? Dead wrong. An honorable vocation, that of Mortician, a lot of caring involved. My cousin has chosen the line as well. All the best, A.
