JBL 4369 announced

[mjgraves]

The first studio I worked in had 4435s flush mounted into the wall, but the studio wall was built for it. So, they were exactly aimed at the mix position. It was a proper live-end, dead-end room. That effectively enlarges the nearfield experience.

I have had the pleasure of using the 4435 and in my humble opinion; it is one of the best speakers I've ever heard. especially for orchestral music.

I had a chance to listen to the JBL 4369. As expected, it struck me as essentially a 4367 with more powerful and extended bass. The sound was excellent overall. However, considering the price difference, I think a used pair of 4367s would offer much better value. That said, I did like the more substantial and impressive appearance of the 4369.

44 were the first of the softer sounding JBL's. The top end just wasn't there though and they really did ask a lot from the units, crossing the "15 very high, around 1KHz to a "1 with aluminium diaphragm, 16KHz -3dB
Makes me wonder what a TAD2001 or 2002 would do on these horns.

I am only interested in one thing that matters the most for me about these speakers: If the woofer has TCR voice-coil wire, to give very low compression and very energetic sound.

You got me to look up what TCR (temperature coefficient of resistance) is, and found this JBL patent. So, for a 2x difference in TCR, only when the voice coil temperature exceeds 200 °C, SPL over 120 dB (1 m, free field), the difference was only over 1 dB, roughly the just detectable level. (The 1 dB level is just my guess for 120 dB SPL. It is more applicable for the healthier SPL levels.) The difference didn't exceed 2 dB when the curve stopped at ~520 °C (melting temperatures of the common aluminum alloys start at the high 500's °C, depending on what elements are in the alloy).

I doubt it "matters the most" to most people.

Hi, thanks for the detailed info. Greg Timbers said about 2216ND and 2216ND-1 that due to the TCR voice coil the woofer is very kicky and, actually owners reported that one 2216ND kicks harder than two 1501AL of the Everest. Isn't that cool ?

IIRC the 4367 has similar power compression measurement as a 4435 which uses two 2234H.
In any case long term power compression is not a really useful measurement for home use, but instantaneous power compression (what Geddes calls power distortion) probably matters quite a bit.

Hi, this instantaneous power compression is exactly what TCR adresses, right? Have i got this wrong?

TCR is all about the temperature of the voice coil. Thermal is usually a slow process. The warming up of the voice coil is dependent on its thermal mass and the power dissipation. The formula is:

For aluminum, c = 0.897 J/g·°C. If the voice coil mass, m, is 10 grams, and Q = 1 J, then ΔT = Q/(m × c) = 1/(0.897×10.0) = 0.11 °C.

Since 1 W = 1 J/s, if we have a voice coil with a mass of 10 grams and no heat loss to the surrounding, the rate of temperature rise with 1 W power is 0.11 °C/s.

Therefore , to raise the voice coil temperature by 200 °C in 1 second, you need a continuous power of 1800 W. 1 second is a relatively long time for music transients.

Under what conditions exactly did you register instantaneous power compression when listening to music at home?..

I have had the pleasure of using the 4435 and in my humble opinion; it is one of the best speakers I've ever heard. especially for orchestral music.

I've always wanted to hear a set driven bi-amped. I thought that an active crossover could be a significant advantage.
