I'll say this for you ntrain, you have a knack for backing out of your useless bull**** by posing it all as fact and answering every query for proof with another question. You've been outed as ridiculous with outrageously unscientific theory, you've been outed as being untruthful, all of your misinformation has been addressed and refuted, and yet you keep coming back. I'm sure someone, maybe your mother, appreciates you, but it's apparent that nobody here does. Why do you stick around? I'm honestly curious. Is it the attention?

Is this the same guy that got outed on the Emotiva forum when it was discovered he was ripping people off on a Harley Davidson forum??

Nethawk,

You really shouldn't hold back as it is best to express your true feelings. Just so you know I agree with your post 100%. The guy is definitely not dealing with any factual information in the least. I'm just surprised that he has not been totally ignored as he really should be.

I believe he is the same guy. If not he certainly acts the same.

Proof? Just because you state something doesn't actually make it true. How does a speaker with a ragged on axis response, horrid non existent off axis response, and all kinds of IM distortion from producing bass have less coloration?

There are to many examples of high sensitivity, high power handling multi driver speakers to even try to bring that up lmao

Some trade offs are bigger than others. How are you defining dynamic? If it is not dynamic; is it due to a memory effect, power compression, or less energy storage? IMO, tweeters and drivers with less energy storage may sound so called less dynamic?

Rolloff is related to the radius of the tweeter. Curtis already corrected the top end roll off. The RAAL also has excellent CD off in the horizontal axis. I would agree with what you said if you enjoy doing squats and jump roping near the speakers. Salk states that the dual ER15 or W18 drivers will be damaged before the RAAL is damaged. That includes their MTM speakers.

One of the best sounding un-EQ'd speakers I've heard with incredible treble came from a pair of Maxxhorn's. Single full range driver, no xover. Incredible detail and dynamics in the treble, solid, detailed smooth bass down to 30hz. All from a single 5" driver.

So you criticize the RAAL above for those features but then a 5" full-range driver is excellent? This larger diameter driver has better high frequency extension than the RAAL tweeter? better off-axis response than a high end tweeter? all while possible suffering from non-perfect BL curve, Le(i), Le(x), CMS(x), IM, and limited power handling since it needs less wire in the motor to extend to the treble region. Full-range drivers do have their advantages though. I enjoyed the Jordan driver when I had a chance. Imaging is one of those as long as there is no excursion. I don't disagree about you enjoying their sound.



I will get back to you on passive versus active crossovers. The Salk employees could not tell a difference when using an A/B switcher when not EQ the bass. Speaking of Salk, they produce a speaker with the Jordan when asked. I plan on asking a few more companies regarding passive versus active.

Why does any of this matter if passive xovers dont hurt or alter the audio signal?

How about knowing what your talking about?

Who is to say a good single full range driver is going to have a ragged on/off axis response? Or IM distortion from playing bass frequencies? If you actually HEARD(which you obviously havent)a good point source speaker with both a low Fs and low VC inductance you wouldn't even be quoting this.

Tossing out some of the specs of a ribbon tweeter and what its capable beyond what you can actually hear is great, but the most important driver and frequency range is the MIDRANGE. When you dont have to couple a midrange driver or share midrange frequencies with a xover and a secondary driver that doesnt even disperse the audio wave in the same uniform pattern as your most important driver, you already have a disadvantage in design in many important audio aspects.

What part can't most people hear? I don't think anyone said the importance of the RAAL was that it can play past 20 kHz.

Low Fs drivers have lower sensitivity and drivers with low VC inductance have less power handling. Don't forget to factor in BSC when looking at drivers. Didn't you mention earlier, what if you want to play louder? Variations in inductance across excursion will change the frequency response of the driver also.

Jordan JX-92S

From Zaph Audio.
Comments: Very wide and smooth frequency response. This is a full range driver that actually sounds good run full range with a simple baffle step compensation circuit. When you get 10 degrees off axis however, the high end disappears from beaming. Decent overall performance, but a poor value. A pair of better sounding 2-way systems could be built for the cost of a single JX92S. If you're convinced there's some sort of magic to a full range driver, this is one of the best, far surpassing most others I've come across. Tested March 2008.
