Sorry, it was James Bullough Lansing and not John as I said in the video... en.wikipedia.org/wiki/James_Bullough_Lansing

[@MrBradleya16]

got a couple of 2441s in 3 way tops, why they so sought after?

[@zambotv8150]

They're old, they have Alnico magnets, they're super efficient. You can drive them off a 5 watt valve amp.

[@MrBradleya16]

Awesome, do you know where replacement, diaphrams can be bought?

[@MrBradleya16]

Just incase lol

[@zambotv8150]

@@MrBradleya16 They're hard things to kill buddy. I think they're still available online?

[@puciohenzap891]

@@MrBradleya16 You can get different replacement diaphragms: chinese titanium knockoffs, original D16R2445 titanium, Radian 1245-16 (aluminium with mylar surround) or Truextent BEX4016 beryllium. The original D16R2440 and 2441 are no longer available.

The 2441 had a silver ring to help it reach 15KHz.

[@zambotv8150]

Wow you know your stuff

2441 has 1 more slit in the horn over the 2440. JBL 2440 also has a different diaphragm that's not available anymore and it's frequency response plummeted above 9KHz. I think the Radian 1245-16 would be closer to the D16R2440 than generic titanium knockoff diaphragms from China.

@@puciohenzap891 To plummet above 9KHz is actually an advantage. Midrange horns has no business playing above 10kHz. It just doesn’t sound nice. Something about breakup. Beryllium has the highest and nicest breakup. But is toxic to manufacture, and possible to use. Symtoms develop slowly - scary stuff. Better to use dedicated drivers for mids and highs, with dedicated horns. Well, except a widerange speaker has no crossover in a sensitive frequency range for the human perception. There is something about Radians diaphragms that sound dark and lifeless.

Its a real shame what's happened to JBL its just became a souless brand name pumping out Bluetooth speakers, completely abandoned there professional and standard loudspeaker division. These investor geoups even of it is Samsung are savage and do nothing but destroy companies, tannoy got f,ed in a similar way

[@puciohenzap891]

JBL also did a mistake by targeting the Asian market and splitting the product lines. EU and NA got almost nothing while all the nice exotic models went to Asia. On sites like Hifido you'll often see models never offered elsewhere.
