Default Alternative to Jordan JX92s ?

Although very happy with my drivers, playing devils advocate I wanted to try out an alternative to Jordan JX92s drivers.

I need a driver with the same diameter chassis of 140mm though which may make it difficult or impossible to find an alternative, anyone have any ideas ?

They are available in Poland and probably produced here but I'm not sure - need to ask my friends. The price is 25Euro each so you can buy them blindly. I can do some comparison with Jordan JXR6 in the same setup when will back to my country. Spending some time with Jordans i see the importance of stiff cone. Despite some amount of resonances you can render percussive instruments very well. The impulse response of JXR6 unit is pretty similar to the raw Manger MSW. The sound is comparable with reference transducer - Shure E2 headphone.

I love to see a proper front horn loading for JXR6 - I know that the phasing plug is very hard to manufacture for such driver but initial test with horns indicates it is a possibility to build very musical transducer.

It is a good idea to use STX for a baffle step correction:

Yes, Diskus is great idea. This must work really fullrange and fullbodied, but Manger is definitely excellent driver only from 200Hz up.

Logically Manger is one of the worst bass drivers available. Still I like the bass from fullrange Manger very much. If anything else, it is "the fastest bass possible" at some musical instruments but the same recording shows also inferior control over other low frequency sounds.

You can think the Manger is the worst of all loudspeaker drivers because it is the worst pistonic driver

BUT use MSW correctly and then listen, please.

One of the first Manger patent (US3686446) was push-pull transducer with double magnet and voice coil. It had no impedance peak at Fs (like a true aperiodic loading). Could be a good bass driver.

My JXR6 is to small for drums (e.g. Manger CD last track) so that I will need a bass extension. My first move will be cheap 12"-15" isobaric. What do you think Jirka about adding side Bandors 150 to the main JXR6? Side Mangers are just filtered by LP at 1000Hz? This will cost slightly more than a pair of Mangers but the holistic transparency will be excellent. I do not see much that can be improved listening Jordans (except SPL at far field).

Jirka - are you planing to buy Jordans? I can't find any reasonably priced transport from Kassel to Mellrichstadt so that you can be quicker than me in comparisons

Two JXR6s per side would give you a cone area only slightly less than that of a pair of JX92s and would help fill in the lower mid-range if using the drivers in cabinets away from walls. This would be at the expense of bass extension - you'd need a sub to take over below 100-120Hz, depending on cabinet size.

Shouldn't be a problem for anyone with, say, a REL ...
