Feedback on The Audio Auction site

So I bit on a pair of 2440's with a bit of trepidation. They state on their site that they will be either 2440's or 2441's with the 2440 diaphragms. Mine showed up with 2441 badges and 2440 diaphragms.

As they came out of the well packed box...

They work and look far better than I expected.
And black???

I got four black and four gray from them. I can't remember by the numbers which color came first but mine are good too. No issues.

Hey 1Audiohack. Were the 2241 sold to you as being 2440 or 2441?

[1audiohack]

2441's and they are/were.

You are very lucky you got the rare 2440 diaphragm; this one comes as close as you can get to JBL's 2440/375 version of the original Western Electric 594-A diaphragm__the difference is that: "594-A' used a very special Dural-Alloy" no longer available. This alloy was capable of heat treatment to extreme stiffness yielding a blue-grey finnish. This gem looked like it had just crawled it's way out of hell.

The 594-A had a true mass-break at 7,500 Hz and it rolled off with a pure 6 db, +/- 0.10 db slope out to 20,000 Hz, which you could tip up to a yield perfectly flat response out to 20,000 Hz with a simple RC in the amplifer __ sweet and clean, extremely rare.

The 2440 vs 2441 issue: __ 2440 has 20,000 gause flux density which yields supirior damping around the typical 300 Hz diaphragm resonance, compared to the 2441 flux density of 18,000 gause. Most horns do not provide driver loading below 500 hz resulting in "horn honk" right in the middle of the critical mid-bass spectrum where the voice fundamentals fall __ not to mention "120 to 600 Hz" spectrum where the true beauty of the bass harmonic structure falls.

You really need a horn that provides the driver "full acoustic resistance loading" down to 120 Hz" to prevent horn honk.

Other than that __ it is well known that the higher flux density in HF drivers contributes significant "cleaner high frequency performance"__ Think about it: "All the little HF secondary resonances, aka: tinkles you percieve as "Better HF Sound" are due to diaphragm under-damped stresses of the voice coil tugging and pushing the diaphragm dome around.

I would not worry to much about this, 2441 has a very nice high frequency tinkle that everone loves.

I ordered a pair of 2405's and a pair of 2405H's.
The 2405's did not have badges but otherwise in good condition the 2405H's have badges and are in very good condition.

I am pleased.
