DrWho Posted May 28, 2005 Share Posted May 28, 2005 I've been browsing the web lateley for all sorts of horn loaded speaker providers and I came across this website that sells all sorts of lines and I came across these two speakers: http://www.usspeaker.com/beyma%20CP25-1.htm http://www.usspeaker.com/jbl%202404H-1.htm Is it just me or are they nearly identical? I know the specs are slightly different, but they're also really similar at the same time. Is Beyma a rip off company (kinda like behringer)? (for the record, i have no issues using "behringer" products) Quote Link to comment Share on other sites More sharing options...
Audible Nectar Posted May 29, 2005 Share Posted May 29, 2005 The Beymas are supposed to be KILLER tweeters......these are the tweeters that Al Klappenberger uses in his modded Belle Klipsch. The JBL's are no slouch either, knowing what they have done with their high end efforts. I'll leave it to the rest for comparisons, as I haven't used any of these - but have sure seen lots of comments about both here in the past.

Al Klappenberger Posted May 29, 2005 Share Posted May 29, 2005 Guys, All I know for sure that the Beyma CP25 runs rings around the T-35. I couldn't say that it's better than the big JBL since I have never gotten my hands on one to evaluate. I suspect it's a very good tweeter too. My guess is that it would come down to the price. The Beyma is a lot of bang for the buck! Al K. Quote Link to comment Share on other sites More sharing options...
sfogg Posted May 29, 2005 Share Posted May 29, 2005 Al, If you want to try out a JBL I can lend you one (or more). I have three sitting on a shelf. One is pretty much brand new the other two I think have had their diaphragms replaced at some point. Shawn Quote Link to comment Share on other sites More sharing options...
ZAKO Posted May 29, 2005 Share Posted May 29, 2005 The Beyma & JBL 2404 look simmiler BUT are quite different. If you look closely at the JBL, there is a small diffraction slot at its throat area plus a phaze plug. the baby cheeks are slightly different. the slot is supposed to be mounted verticly. although it really could be rotated in any direction. The vc/magnet is very powerful. The Beyma babycheeks are shaped slightly different. The JBL dispersion is 100 degree horizontal & verticle. I dont know the dispersion pattern on the Beyma.

Al Klappenberger Posted May 29, 2005 Share Posted May 29, 2005 Shawn, I am tempted to say yes to the offer of a loan of the JBL, but to actually listen would require all three of them! I could run curves on one sitting on top one of my Belles. That way I could compare it to the Beyma. I don't like to do listening tests anyhow since my opinion is of no more value than anybody elses. That's why I generally limit myself to instrument tests. On the other hand, some comparisons are so obvious it's hard to keep my mouth shut, like when I replaced the K500 squawker horns with Altecs!

J.4knee Posted May 29, 2005 Share Posted May 29, 2005 Al your opinion is highly valued around here period! I would love to hear a comparison between the K77/T35 and Beyma's or JBL 2404's. Quote Link to comment Share on other sites More sharing options...
sfogg Posted May 29, 2005 Share Posted May 29, 2005 Al, If you wanted to try all three I could send them to you. Would be interesting to know if they would work properly with your ES networks in case I ever decide to try them up top on my Altecs.

markus111 Posted May 29, 2005 Share Posted May 29, 2005 I can't speak for the Beyma, but the JBL absolutely embarrases the T35. It's a very nice sounding tweeter on the K Horn, and adds tremendously to the sound. Mark Quote Link to comment Share on other sites More sharing options...
DrWho Posted May 30, 2005 Author Share Posted May 30, 2005 Yikes, if they're how y'all are describing it then how come more people aren't dropping the relatively small amounts of cash for these upgrades? $150 for a better tweeter doesn't sound too expensive to me. Do you guys upgrade the mids too? I got to looking and found these two: http://www.partsexpress.com/pdf/294-415.pdf (JBL 2446 on a 2380A horn: http://www.usspeaker.com/jbl%202380A-1.htm) and http://www.partsexpress.com/pdf/264-216.pdf (http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=264-216 on this horn: http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=264-328) Quote Link to comment Share on other sites More sharing options...
Al Klappenberger Posted May 30, 2005 Share Posted May 30, 2005 Shawn, Ok.. Send me the "virgin" one that is representitive of a new on straing out of the box. I'll do curves comparing it to the Beyma. You already have my address I assume. BTW: My networks are compatable with ANY 8 ohm tweeter that is at least 100 dB SPL sensitivity. It should be in the 103 dB or higher range though. Thanks! Al K. Quote Link to comment Share on other sites More sharing options...
Marvel Posted May 30, 2005 Share Posted May 30, 2005 Dr. Who, The two mid drivers you posted links both have 2" throats. This would obviously mean a change for the horns as well. Pretty soon, you find you have built a whole different speaker, and spent more money on it than on the original Klipsch. This is basically what DMan has done. He designed his own corner horn, used a 2" throat mid and JBL 2404 for the tweeter. It is different all the way 'round. While buying better parts doesn't necessarily lead to better sound, I think Dana would say that in his case, the difference has been most positive.

formica Posted May 30, 2005 Share Posted May 30, 2005 I may be mistaken, but I seem to recall djk comparing those two tweeters at some point... but those who know him better would be able to confirm this. ---------------- On 5/30/2005 1:38:13 AM DrWho wrote: Yikes, if they're how y'all are describing it then how come more people aren't dropping the relatively small amounts of cash for these upgrades? $150 for a better tweeter doesn't sound too expensive to me. ---------------- The Klipschorn was value engineered (like all modern products) so it does leave room for improvement on multiple levels. You have crossovers, tweeters, mid range, veneers, etc... That's what this forum section is all about. I think it comes down to the law of diminishing returns... and not all the members have the capability (or interest) of trying these mods. They aren't always just "plug and play"... There are actually quite a few members who are running Klipsch bass bins with fully customized uppers... (Al, djk, Qman, John Warren, sfogg, etc... ) Mine are still stock... but I'm also still in diapers... Rob Quote Link to comment Share on other sites More sharing options...

D-MAN Posted May 31, 2005 Share Posted May 31, 2005 I will go as far as saying this, and it's pretty inarguable... The JBL's cost more than the Beyma's. My understanding is that the Beyma is intended to go toe-to-toe with the JBL tweeter at a lower price. But I've never heard them, so I cannot speak to the value-to-performance ratio. Al Klappenberger's pending instrument test should help in this matter. I love the JBL 2404H's but only after they are well broken-in. I thought that I got snookered when I first hooked them up, but eventually they smoothed out. They will be a bit "hot" on a stock Khorn lashup, but definitely listenable even without attenuation (I ran mine open). I'm now using Al K.'s ES networks at 5800Hz with an attenuation and they are quite happy, and so am I. I still think that the JBL's cost too much, but what is one to do?!

michael hurd Posted May 31, 2005 Share Posted May 31, 2005 Could always sniff around for a few KSN 1016B piezos, and use those a'la MCM style. do a little searching on the audioasylum high efficiency forum. They require a network for best results, PWK built such a network. Quote Link to comment Share on other sites More sharing options...

Does anybody have an idea as to their maximum acoustic output? A great sounding speaker isn't very cool if it can only do 100dB http://www.itcelectronics.com/pdtl.asp?P=6220 (which is like the K-77 tweeter) http://www.partsexpress.com/pe/showdetl.cfm?&DID=7&Partnumber=272-100 (a whole different animal, but theoretically still good). DJK comments on it here: http://www.audioasylum.com/scripts/t.pl?f=pi&m=574 I can also find the threads discussing the crossover as well.

But take a minute and look at these! I think Mike is onto something here, and they bear checking out! And for the price, it's hard to go wrong!
