Adding colour to a driver

[tade]

Off-topic discussion split off from Fullrange speaker gallery


Enabling is very good at adding color to a driver! Though adding anything to a driver can hurt it's performance.

The 1st it can certainly do:



And if done properly can decidedly improve the performance (i expect you would consider me biased, and likely think that all those who really like their EnABLed drivers (ie almost all ofthem) are suffering from mass hallucination )

Not only can it improve the appearance, it improves the sound on many drivers.

Just to let you know, the fact is that many drivers can be "changed" for better performance. I've done it, as have many others, on this and other forums. Not only can a modified driver sound better, but there have been measured improvements as well. Back a few years ago on the old "Bass List", a number of us were amused that one of our members, Magus Idland, was cutting up the cones on his speaker cones and gluing them back together.
I'd call that a change, and he claimed it improved the sound. Some months later he introducted the "cut-cone" drivers on a whole line of his Scan-Speak drivers.

As a gentle reminder, when you make general statements (like you have), you really should have some facts to back it up, otherwise people will start to suspect that you're a clueless dweeb.

I second with Dave that all of those people are suffering from a mass hallucination.

I agree with TerryO about having substance to our claims, otherwise people will claim you are a clueless dweeb. Keep in mind that substance must include evidence, other than pseudoscience, and a wide following.

I'm not familiar with the old "bass list". What is it?

I would be as careful as dave and the rest have been about applying a damping to the cone. I believe you start heading into polypropylene territory; overdamped. As for pretty dots, put them wherever you like. Though I suggest you put them where you think they do some good. That will make you feel loads more positive about them being there!

Cheers.

tade,

Have you heard properly EnABLed drivers?

Dave,
I've heard a lot about them.

I certainly have, in a blind A/B comparison put on by the Pacific Northwest Audio Society.
I should mention that out of the 25+ people that attended the meeting, one person thought they couldn't tell a difference. Afterwards, when people were allowed to know which driver they were hearing, the general consensus was that the EnABLed pair of speakers sounded better.

As for the science involved, I attended a meeting of the State Emergency Preparedness Committee (of which I'm a board member), to listen to a presentation by a GeoTech Engineer that had just returned with his team from Sendi, Japan. He presentation included a slide show on the damage suffered in the recent quake. Afterwards, I spoke to him at length about seismic activity and the correlation to Bud Purvine's EnABLed cone treatment. He felt that the correlation between the two was quite high and agreed that transverse, rally and loop-back waves would be involved with any vibrating membrane. He did allow that at Sendi, there was no evidence of "figure 8" waves which Bud has demonstrated, although he said that the lack of an unyielding terminus was probably why they hadn't been a factor at Sendi.

Terry, did the test include drivers that were doped and enabled, or just enabled? Doping the cone changes the frequency response and is audible. But the real question is whether just the enabled drivers were preferred in such a listening test.

That's a good question, and offhand I'm not sure. I can tell you that Bud has modified the EnAbl treatment since then and claims that it's even better than before.

I've done a fair amount of cone doping in the past and it certainly helps a lot of drivers. I was awfully sceptical about Bud's methodology initially, but I've heard enough examples (dozens), on a variety of drivers, to feel it's worthwhile.

Any of the metal coned Mark Audio drivers will only have EnABL -- given the timing the will also be EnABL2
