DIY Paradise is pleased to have acquired Jordan distributorship for Malaysia, Singapore and Thailand.

JX92 Full Range from 40Hz to 20kHz!

Full specs here!

Just for fun, we put in the JX92 into our Hedlund Horn. Man, this driver can seriously do bass! The bass was rattling our ceiling!

October 2006 Update! Jordan JXr 6HD is here as well!

The widest bandwidth 2 inche driver ever made! 70-30kHz! (talk about great mileage!)

Utilizing a wonderful technique, you adjust the bass frequency by varying the volume of the enclosure. The larger the volume, the lower the bass.

They are best suited to sealed boxes ranging from 1 litre to 3.8 litres for each driver. The larger the volume, the lower the Fo of the driver. For example:

1 litre = Fo of 150Hz to 160 Hz depending on box shape and design
4 litres = Fo of 100Hz to 110 Hz depending on box shape

IMPORTANT NOTICE
The JXr 6HD is an advanced audio driver with a single mechanical suspension. This concept allows system designers to vary the operating frequency (Fo) of the driver without the use of a crossover. We strongly recommend the use of sealed box designs which allow the driver to make use of the air volume to act as a damping force to control the lower frequency response. Since the design has no secondary damping mechanism, it can be overdriven more easily than conventional drivers. If drivers are subjected to extreme low (below 100Hz)at higher power levels can result in excessive oscillation risking damage to the coil assembly. The Warranty WILL be void if damage to the coil assembly is found while investigating a claim.

I built my JXr 6HD tower!

Let’s Get Horny!

Most folks have no idea the potential of a quality single driver. Just because they have listened to some budget drivers (which are heavily compromised) in some dingy cabinets, they quickly base their opinion on how the single driver sounds. Very quickly, they label it — “the single driver sound”, associating with “not much bass, not much highs, only midrange…” blah blah blah…

To a certain extent, that’s true. You see, to build a single driver speaker properly, is no easy task. As you have already thrown away the fussy crossoverr, you must now pay more attention to the enclosure. Out with the electrical and In with the mechanical equalization. Never for once should you take the easy way out with the enclosure. Unfortunately this is the problem with most Diyers. For various reasons, ranging from the absurd “no money to build quality enclosure” to the most common “do not know how to build”, most Diyers just take the short cut and build the easiest box. Believe me, if your speaker driver is some vintage specialty like the Coral Beta, this is SACRILEGIOUS!

If you aren’t serious with the enclosure, then my advice is DON’T BUILD IT. You see, for sure there isn’t such a wide bandwidth driver that could do everything right, so the poor driver definitely needs your help to help her sing. Usually it is the bass region which is most difficult. This is why you see many drivers in the market that are either bass, mid-bass, or mid-highs. Because it’s easier to make such a driver rather than a single fullrange driver.

So when you decide to go for single drivers, then you need to be serious with the enclosure. If you don’t want to be serious with your fullrange speaker driver… boy, you don’t deserve her!!! *Hint, Hint* *Pass them to me!*

And my recommendation is very simple. It’s all horns, horns and horns.

Forget about bass reflex, sealed box, transmission line, TQWT, Voight pipe, open baffles, your closet, your car booth (yankees call it trunk)…

Get Horny!

Hedlund horn, back loaded horn and spiral horn. I have tried these and heartily recommend you try them as well. Believe me, everyone needs a license to be horny from time to time! Of course, there is the front horn as well but due to size considerations (front horns need to be HUGE to do bass), they are usually utilized above a certain frequency, say 150Hz rather than go all the way fullrange. To go all the way down to say 50Hz, you need to be either a hermit, a bachelor or have the most understanding spouse in the world. (Teach me, teach me how to convince my wife!)

For the rest of us conventional folks, go horny!

Whole Lotta Cabs!

Closer view of the pair. As you can see the side vented horn is slightly bigger in size.

Aha, see the vent? Both vents must be facing OUTSIDE. I tried them with the vents facing inside and the bass just sounds weird. A bit like me, after too much beans…

Okay, we listened to both enclosures in 2 different systems. Which pair do you think sounds better? Here’s a hint.

I’m horny. Horny, horny, horny!

Yeah, without a doubt at all, all 3 of us unanimously prefered the side vent horn. Actually both cabinets are okay midrange upwards but as you come to the lower midrange and below, then there is a clear distinction.

The side vent horn is cleaner, clearer, more detailed and faster.

The transmission line’s bass, in comparison, sounds distorted, muddy and blurred.

Well upon closer listening you’ll realize that once the bass lines get muddy, the “blurriness” extends to the mids as well. Now things start to get really messy now. This is why all things considered, I’d rather have a clean 70Hz than a muddy 40Hz.

Now please note that I’m not trying to put down the Jordan transmission line design. By itself, she’s a nice enclosure but when you put her beside the back loaded horn, then the shortcomings become apparent.

The point of all this is that, with your fullrange single driver, you got to take the trouble, do the right enclosure to realize her potential. No easy way out please!

Let’s get horny!

the Fullrange Single Driver

When Gabriel built the mock-up cabinet, I asked him what does he think of the sound of the new Jordan JXr 6HD?

“It’s the Beginning of the End”.

Huh? Beginning of the End of?

“The Beginning of the End of the Fullrange Single Driver!”

If you are a single driver fan, you may be rubbing your hands in glee to read more.

If you are a multi-way fan, you may be yanking out your hair (or whatever’s left of) at such ridiculous statment!

You bet I’m the former!

After Gabriel passed me the cabinets on Friday night, I could only lacquer it on Saturday night. Yeah, time flies faster on weekends!

Then on the Seventh day of the week, it’s crunch time!

	Jordan JXr 6HD in box. {mosgoogle}
	“Father of Full Range” Well, you know Ted Jordan designed the well known Goodmans Axiom 12 right? The JX6 definitely broke new ground with its bandwidth! The pair in the box has the same serial number. They come in matched pairs. So no buying singles okay?
4 liter tower! Very slim, very sexy! Due to the narrow baffle, could use a single solid wood plank here. Wood used here is Resak, very hard, very strong and very durable. Why heck, you could use it to club your multi-way loving neighbour!

I first installed these beauties into my secondary system. Right away they are magical! Wonderful sounding! No harshness, no shouting, just sweet natural music. [some folks pay 4x more moolah for speaker drivers that shout at them. i think this is sadist. you could pay me half the amount and i’ll shout at you!]Thus without further hesitating, plugged them into main system.

If you are building a satelite-sub combo, you can’t go wrong with the JXr!The highs is as glorious as a ribbon tweeter! If you ever played with supertweeters, you know that the 30kHz reach here extends the soundstage as well. My friend kept on commenting, no one will guess this is the sound from a 2-incher!

Man, I couldn’t help spinning CDs after CDs. Yes, a sub will help but forget it for now. Get your “high” here first. Ha ha!

Rarely do we get to listen to drivers of such calibre. Damnit, rarely do we come across one!

Rarely do we get “spooked”.

Rarely do we get “humbled” by 2-inchers.

Mr Ted Jordan, thank you Sir!

To cap off a splendid day, my wife commented, this box looks slim and nice. Perhaps we could use it as a bedroom system… I almost fell off my chair!

Do you think it’s a good idea to suggest a 6 feet subwoofer horn for an ultra-wide bandwidth system in the bedroom? Imagine 30-30kHz of audio ecstasy!

Perhaps I’m pushing my luck…
