Titanium vs Teteron dome tweeters
Now this is very important to me since I researched and found out that my Alesis uses Teteron dome tweeter not silk dome tweeters like other alesis are. Now what what I need to know is what is better for critical recording will the Titanium tweeters like thats are on the JBL S26 be better or the Teteron dome tweeters on the alesis would be better for critical recording?
You are focusing on the wrong thing
The material used to make a dome is usually the most important thing to be concerned with. Overall design and integration into the system is far more important.
Personally, I think the tweeter used in the JBL S series is fairly weak. It lacks extension and detail. It is not one of the best that JBL has produced.
The Alesis, I have never heard, so I cannot comment there. I would be surprised if it wasn't better than the JBL, but that is just a guess. A guess not based on material, but on experience with one, and knowing a little bit about the companies involved.
Dang, I meant NOT the most important thing
No, turning your treble control up won't help. It will give you a nasty peak about 5k but won't do anything about extension. Treble controls are best for toning things down, but they are usually not very effective at that either because the effect is too broad based.
This is getting to ba a little much
All the speakers you've mentioned are solidly built and are liked by some portion of the population. Only your ears will tell you where you fall on this matter.
I think a little more time spent listening to speakers would be more productive than this mental masturbation about constantly comparing specs and asking others opinions. Why so concerned about others opinions?
Sometimes, ya gotta make a decision and live with it. ...or take 'em back after listening to them.
Let your ears do the choosing
The Athenas use a Teteron tweeter too, but I'm not sure if they share any other design attributes, and would rather doubt they did. Again, don't worry about what the tweeter is made of, but be more concerned about if YOU like the sound.
You are really tied into this whole titanium thing. There are some really good titanium tweeters out there. JBL makes some of them. They are not the ones they used on the S series speakers.
I'm not sure of what your goal is here. If you want some small speakers that would work for monitors, there are a ton of them. If you think that a brand that has certain speakers that are used as monitors by some people automatically makes that a great choice for your speakers, you would be making a mistake.
Go out tomorrow and just listen to speakers. Forget about tweeter materials, woofer materials, watt ratings, # of ways, ...pretty much anything you would attach to the decision which is nothing but baggage. What matters with speakers is less of what stuff went into it, but the way it all went together. You are headed down the wrong path.
