Upgrade the speakers? Start over? Go back to point source?

Well, I was in point source when I first started building my speakers , but an array is much more challenging. And I dont get discouraged , specially that I have good assistance from Rick .
I may think of changing the Dayton Aluminum drivers , as I think the aluminium has a sound of itself that may be the reason for some coloration in the midrange . I have to say that to all my friends the sound is impressive !!!

When you come right down to it, many times the composites and the aluminum, and other exotic materials all pale to just plain paper.

So you are actually saying that while you personally have a problem, no one else who listens does?

I know this is a simplified response to a more complicated question.....

I don't know how other people's line arrays are set up but I can handle this by adjustment of the system. I have a pre-amp which feeds the analog electronic crossover. The crossover feeds the three ranges to three separate power amps. The tweeter and the bass power amps have volume controls on them.

This allows me to adjust the intensity of the treble above 2500hz, and the bass below 165hz. When I have a recor4ding with too much sibilance then I turn the tweeter amp down a bit. When I have a recording with too much or too little bass, I adjust that too. Often rock benefits by increasing the bass end a bit, and classical by reducing it.

This is sort of like equalization, but without the same phase issues, I think.

Can others not do this? I made sure that the power amps I purchased had separate volume controls. It also meant that I didn't need to push to less expensive op amps of the Rane crossover too hard, and let the much more quality in the power amps do the job. If you can't find power amps with volume controls, you can always buy a control amp and use that instead. In fact, my tweeters are run out of a 60 w/ch receiver.

That's not exactly what I said !
Critical listening is the issue , and not just demonstrating the speakers to a bunch of friends that do not care about HIFi and are already impressed only by the size of the speakers ....

Which are you? [message #23894 is a reply to message #23893] Sun, 22 July 2007 10:48 Go to previous messageGo to next message

I doubt that I could hear what you claim is the concern. I suspect that your hearing is far far far better than mine.

What exactly is critical listening? I just wanna hear great music as exact as I can afford, and after that I just buy CD's.

Before I stopped posting on the PE forum I asked: "If you could design and build a system that got 95% perfect, but it would cost an additional $2000 and 100 hours of work to make 96%, would you stop and just listen to the music, or would you put all your time into making it 96%? And struggle to keep shaving off smaller and smaller percentages?"

Almost 80% of the people there said they'd go for 96%. And when I asked what they listened to most people described rock groups.

That's when I knew I was in the wrong place. These people weren't interested in listening to music, they we're just compulsive about building bigger and bigger woofers and better and better and better speaker systems, no matter how much more time and energy it cost them from actual listening.

Which are you?

And actually, rather than honing a speaker system to be better each time, they mostly just build a different one than they build from before. One time its a tiny little one, the next time a MTM, then a mini array, than a TL. Not just goes on.

Not me. I built the best I knew how from lots of research, and the money I had available. I'll only upgrade if I can find some change that will show a dramatic, not an incremental, increase in sound quality.

I guess I'm in the same category you are in !!
Music for me is so important ! I am also a guitar player an singer but unfortunately had a medical problem with my vocal cords and I now just listen to music at home and in my car , and what is so astonishing, is that I get amazed how my car sound system sound ( very enjoyable )although it is not so special, I never feel listening fatigued while on the road , but at home I do !!!!!!! and the music I listen to is Jazz ( soft )and the styles that go with it , I guess you understand ( Blues ), Classics etc ...
Hope you get a better picture of the situation I'm having ?
I may have some room acoustic problems !!! but This is beyond my capacities .
