Max2 Posted September 9, 2014 Share Posted September 9, 2014 Im planning on upgrading the mids this winter and was curious if anyone had any insight on the BMS 4592 mid that has the neo magnet ($1300 a pair) versus the 4591 mid ($800 a pair) which is supposed to be identical only it uses a ceramic magnet. $800 is a bit easier to digest than $1300, but I have come too far with my K-horns to settle for less at this point. Anyone have any knowledge on the audible difference between these two? Quote Link to comment Share on other sites More sharing options...
babadono Posted September 9, 2014 Share Posted September 9, 2014 Will the 4591 fit in the top hat? And with what horn? I never knew this ferrite driver existed. I just went with the 4592 cuz it seemed that is what everyone always talked about. So to answer your question, sorry I've never heard the 4591 but the 4592 sounds darn good. Are you dealing with Jack at Assistance Audio? He might be able tell you about differences. Or perhaps he would allow you to try both and keep the ones you like. He let me demo the 4592 coax and 4592 mid only. Quote Link to comment Share on other sites More sharing options...
Arash Posted September 9, 2014 Share Posted September 9, 2014 (edited) I could offer you a pair of NIB 4592nd-mid for the same price of 4591 (800USD) if you could take a trip to Iran postal cost is a killer. I think it would cost ~200USD to ship them to US and post office maggots are hard to deal with specially about things they have no idea about Edited September 9, 2014 by Arash Quote Link to comment Share on other sites More sharing options...
jannegard1 Posted September 9, 2014 Share Posted September 9, 2014 i have the bms 4591mid driver 16ohm and use gregs volti horns in my klipschorn the drivers are big but there is no problem the magnets are bigger then 4592 drivers save some money and bay 4591mid drivers Quote Link to comment Share on other sites More sharing options...
jcmusic Posted September 9, 2014 Share Posted September 9, 2014 I use the 4592 mid driver 16 ohm version with Volti Audio's tractrix horns and I am never looking back. Never heard the 4591's though but, I don't think the 4592's will let you down... Quote Link to comment Share on other sites More sharing options...
djk Posted September 10, 2014 Share Posted September 10, 2014 If you tweeter can go to 4Khz, the Community midrange driver sounds better than the BMS midrange driver, and is less money as well. Quote Link to comment Share on other sites More sharing options...
absolve2525 Posted September 10, 2014 Share Posted September 10, 2014 Which model Community driver? Quote Link to comment Share on other sites More sharing options...

absolve2525 Posted September 10, 2014 Share Posted September 10, 2014 Is that available in 16ohm? What qualities do you find better the BMS? Quote Link to comment Share on other sites More sharing options...
Deang Posted September 10, 2014 Share Posted September 10, 2014 Compression drivers typically have a 10:1 compression ratio, so there is quite a bit of "squeeze". The M200 has no phase plug, so the ratio drops to 4:1 (same as Palladium midrange). The sound is less "forced", and takes on more of an effortless quality. I would buy it with the killer matching tweeter. Quote Link to comment Share on other sites More sharing options...
Arash Posted September 10, 2014 Share Posted September 10, 2014 I think BMS should be bought in 16 Ohms version. 8 Ohm would be more difficult to attenuate Quote Link to comment Share on other sites More sharing options...
djk Posted September 10, 2014 Share Posted September 10, 2014 (edited) http://www.theaudiobeat.com/visits/avantgarde.htm Community M200 midrange driver, Beyma CP380M for the tweeter. Edited September 10, 2014 by djk Quote Link to comment Share on other sites More sharing options...
Arash Posted September 10, 2014 Share Posted September 10, 2014 FR speakers in front loaded horns have least compression factor, that's why they sound much more natural and open and the sound is relaxed and easy to ear. once one hear a good FR (TangBand, Lowther, AER,...) in a horn, he won't back to the CD + horn combination. but they are less efficient of course. I'm just amazed why horn loudspeaker manufacturers don't use this concept. a reason could be because the big FR speaker in big-throat horn will be visible from outside and they just can't sell the final product for x100 because customer can see a 200USD Tandband speaker is there! but one can't see a Beyma CD in a Trio as long as he has not bought it.

Max2 Posted September 11, 2014 Author Share Posted September 11, 2014 Thanks for the replys. I read a little on the M200. It seems they don't go near as low and it has been said they shouldn't be ran above 4K? Quote Link to comment Share on other sites More sharing options...
djk Posted September 12, 2014 Share Posted September 12, 2014 "it has been said they shouldn't be ran above 4K?" Why do you think I said: "If you tweeter can go to 4Khz" "It seems they don't go near as low" BS, the low frequency response is largely a function of the size of the horn.

muel Posted September 12, 2014 Share Posted September 12, 2014 I think he was just referring to the specs which suggest a 500hz crossover. What is your crossover? Quote Link to comment Share on other sites More sharing options...
Fjd Posted September 12, 2014 Share Posted September 12, 2014 (edited) I think he was just referring to the specs which suggest a 500hz crossover. What is your crossover? I highlighted 400 Hz to 4000 Hz from the spec sheet. You have to look at the type of horn used and I believe that the pro environment would suggest the higher crossover point. I suspect that a horn with a 260 Hz cutoff like the Volti or 310 Hz cutoff like the Eliptrac in the home environment would probably give slightly more on the low end than the Community SH494 horn and work fine in the 400 Hz to 4000 Hz range.

Dr Morbius Posted September 12, 2014 Share Posted September 12, 2014 (edited) That's some photo! Those horns are beautiful!!! Edited October 5, 2014 by Dr Morbius Quote Link to comment Share on other sites More sharing options...
Max2 Posted September 12, 2014 Author Share Posted September 12, 2014 Im running the Volti 260's. I also have the CP25 Beymas, but I don't know if they would drop to 4K. I just updated my X-overs with Deans Super X's, so I will be leaving them be until the cotton grows a little higher. It seems 4K would change the overall spectrum of the CP's that may or may not be to my liking. The CP's are already too hot with my k55's right now and I was looking forward to going a db or two hotter with a two inch mid to make up instead of padding the CP's down, in the end I may have to though to get things balanced. I could live very easily with the 260 wood horns, the K55's and the K77's as it is an excellent combo for my ears, but the grass is always greener. I have been in and out of hobbies all my life, but music and Klipsch speakers have never gone away. I can't think of a better "item" to upgrade or spend money on. Never thought I would have more money in upgrades for my K's than what I paid for them, but they have come a long way in sound. 2 Quote Link to comment Share on other sites More sharing options...
