Chris A Posted January 16, 2021 Share Posted January 16, 2021 In the meantime, my hope is that this thread's OP better understands the choices between drivers, and is relying a bit less on hype and purely subjective statements. I do trust some ears, others not so much, and still others are a little obscure to read between the lines. I choose an open information approach... 😉.  I hope it's useful to him.  Chris Quote Link to comment Share on other sites More sharing options...

As the gentleman in the video eluded to, you have to know what you want. I didn’t choose the axi2050 blindly. All the measurements that I did led me to one thing......it measures very well. Now how does it sound...... that is THE question that your are most qualified to answer at this time, aye? BTW, will the new Jubilee II have 4 class Dpower amps to go with the active Xover? Should be plug and play to the customer with a lot of money and little technical knowledge beyond just plugging in 2 wires per driver.

I'm thinking you may be right, based on all the technical data that ChrisA has provided to this forum. 1 Quote Link to comment Share on other sites More sharing options...

mark1101 Posted January 17, 2021 Share Posted January 17, 2021 If I got these new drivers I could eliminate the mid bass module on my MCM setup and reduce it from almost 9 ft. tall to just over 6. If I decided not to have a tweeter it could go from a 4 way plus subs to a 2 way plus subs and be shorter than my Jubs. Just saying.......

I had the privilege of hearing original diaphragms with the 1132 driver on my S-MWM setup. I also had the chance to hear those same drivers on the S-MWM's with Roy's new tractix phase plugs and the difference was not subtle. I don't know what Celestion does for phase plugs but I would not be surprised if Roy sticks his own design in there.  Quote Link to comment Share on other sites More sharing options...

Â I would be surprised if he did, since the driver is not made at the Klipsch factory like the K-1132 and K-1133 is. Quote Link to comment Share on other sites More sharing options...

Â I can't tell much detail from the artist's rendition, but I like what it represents. Looking forward to seeing the real thing and reading some listeners reviews.

Khornukopia Posted January 21, 2021 Share Posted January 21, 2021 BTW, it is BMS.  🙂 1 Quote Link to comment Share on other sites More sharing options...
Chris A Posted January 21, 2021 Share Posted January 21, 2021 If you're referring to the driver schematic animation from the released video, that appears to be a Celestion Axi2050 with an extra insert after the phase plug--within the throat exit. That's why I discussed it in this thread.  If instead you're talking about the OP's subject (BMS 4592ND with or without the added cost shorting ring for high output operation), I don't know if anyone addressed his question. If the OP can afford the shorting rings and typically plays his setup near PA levels, that would be the desirable option. Otherwise, the stock (no shorting ring) driver appears to be good enough for home hi-fi duty (i.e, well under 105 dB at 1m).  Chris Quote Link to comment Share on other sites More sharing options...

That's a pretty big waste of money, IMO (...always...), because the Be is there almost solely for the 10-20 kHz octave--certainly anything above 6 kHz. I don't know why anyone would put a Radian 950BePB on a horn, and then roll off the output at 6 kHz. Get rid of the separate tweeter driver and horn, instead. Its ability to play cleanly above 6-10 kHz is why the 2" Be diaphragms came into existence.  Chris Quote Link to comment Share on other sites More sharing options...

I guess like everybody I would have to be able to justify the large expense.  You’re not the first person to say they are clearly better than anything they’ve had before! Thanks Are you sure about that? Ever heard/had the 4001's? Quote Link to comment Share on other sites More sharing options...
