Steve, I have just acquired some single driver jordans, and they seem quite directional, no xover, could you shed any light?
Are you using them singly or in an array? What is their diameter? Are they in a horn or what?Originally posted by Lt Cdr Data

Yes, that can be a good answer, particularly when the mid driver goes a fair way up and down.Graham C
The simple answer is a 3 way, with a wideband mid driver covering the sensitive bits.
Yup, no more Mr Nice Guy.wadia-miester
A serious savaging from Mr 7v therethey must be good :lol: :lol:
Precisely what ATC do, with the mid driver covering 350 Hz to 4 kHz.Originally posted by Graham C
The problems with crossovers have been vastly overstated IMO. .... The simple answer is a 3 way, with a wideband mid driver covering the sensitive bits.
So what does the Active Filter you use do then?Originally posted by 7_V

It acts as a low-pass filter for the bass speakers. It's the full-range speakers that are used without filtering.Originally posted by LiloLee

Not sure about using the JX92 in an array. I have read that you get comb-filtering and a somewhat uneven treble which changes as you move your head because the drive unit centres aren't close enough together at the higher frequencies for them to act as a line source. There's more about it on the Jordan website and other places. The JX53 is suitable for an array if you mount them close together but they only go down to 150 Hz so you'd need a good sub.Originally posted by Lt Cdr Data
I think they are the jx92s, bout 4 inchers
now I see why you use an array, vertically, they do go dull quite quickly.
Probably in much the same way as NHT use their baffle shape.The egg-shape is machined at an angle that reflects the medium and high frequencies downwards and away from the drive-units.
Why do any speakers need a sub? Are they not full-range?Originally posted by LiloLee
So if they are Full Range speakers, why do they need a bass speakers?
I have always told the truth which is that my full-range speakers don't use filters. As I told you, the bass speakers are filtered.And contrary to what you said you do use filters?
I don't have to guess Lee, that's a quote from my web site. What is your point and what on earth has it got to do with the NHT baffle shape?And guess what site this came from?

The dispersion pattern of 4" drivers will tend to be a little beamy at the high frequencies, so you'll probably have to listen on axis to get a decent treble. I'm sure you're already toeing them in to minimise the problem and you may well find that the benefits in terms of coherence and musicality easily outweigh the disadvantages.Originally posted by Lt Cdr Data
Hi Steve, they are used singly in a 4 litre sealed box. Sound pretty superb. Take a little getting used to, but great detail and coherence.

I detect nasty negative vibes this day, what's up? Still "Waiting for your man"?
Digital crossovers are just so flexible (I used a 100th order one with my Tact setup), that they seem to represent a genuine advance over most commercially available boards. Every speaker designer I know (with the exception of you good, if slightly grumpy self) is feverously working away on the technology at the moment.
As for the profiling of the baffle, well it is profiled![]()
