Definitely Alpair. I have the JX92s and Alp6. No contest from 200 Hz up. The JX92s can produce enormous amounts of bass, but I'm guessing so can the larger Alpairs.

rather a lopsided comparison those two - a more valid test of Mark's recent work would be Alp6 and JXR6 or Alp10.2 and JX92s

yes the Alp10 & 12 can produce bass

Alpair 10 versus Jordan JX92 or JX92S. I have all three, have heard each, and like the Jordan JX92 or JX92S better. There are some very good ML TL designs on the Jordan USA site (Jordan's US Distributor for JX92S and other Full Range Drivers)

The old Alpair 10 you have Martin is not anything like the A10.2.

The latest pair of JX92 we have here now is the best set of the 3 we've gotten. Personally i prefer the CHR70.2eN to the Jordan, and no contest vrs A7 or A10.2 (stock or not) IMHO.

Anyone who wants is welcome to come up and make their own judgements.

Dave,

You are right, I have the original Alpair 10 drivers. I have not heard any of the new Alpair line. My opinion was based on my experiences over the past couple of years with two competing driver I have in my collection. It is my opinion based on my system (solid state), my room, and my music selections. Nothing more.

I have implemented several mini-monitor (sealed and vented boxes) and MLTL designs with the Jordan JX92S over the past 7-8 years. Also I've designed MLTLs with both the Alpair 6 and 10 drivers. I expect to work with the Alpair 10.2 in the very near future. Others have duplicated my designs as related in several message threads here on DIYAudio. Hence, a lot of experience with these drivers.

In my opinion the Jordan JX92S and Alpair 10 drivers perform very comparable to each other. You would be pleased with either one. The difference is that Mark Fenlon has been making significantly improvements as he has iterated his driver designs in recent years. He is separating (and improving) the Alpair designs from his past work with Jordan. The newer Mark Audio drivers will out perform the Jordans at significantly lower cost.

I still have several of my Jordan and Mark Audio prototypes if you are interested in hearing how they sound.

Jim

Mine are in your 7 litre BR. I wasn't about to 2nd guess your experience and just went with them.

Where is the spec sheet for the Alpair 10.2? The CSS website says only

Fs = 36Hz
Qts = .35
Vas = 28L

Nothing else. No freq. response curves or other parameters.

The MarkAudio web site still shows the specs for the older driver. What is the holdup?
