JBL 2441 vs 2445 vs 2446

[Lee in Montreal]

I am about to purchase a pair, of the three models mentionned, to be used with 2350 and 2397 horns for home duty (no pea). Which one sounds the best and has the lowest extension?

Were it me, diaphragm materials aside, it would be 2446, 2441 then 2445. I don't have any conclusive evidence to display to support that as yet. I don't know if there is any difference at low frequency, none that I've noticed anyway but I don't stretch mine to either extreme.

If they are all stock and running up to spec, I would go for the 2441 due to the aluminum diaphragm, if you would consider going with a Be diaphragm then all things considered, I would go with the 2446 because of it's more advanced phase plug... that said, I am not sure if the newer phase plug will mate well with the 2328 throats that those two horns use. It very well may be a great match, but since they are different generations they may not be ideal. If that proved to be the case then I would go with either a 2441 or a 2445 with Be over a stock 2441.

agree with you,and 2440 for another choise.
why pay such attention to low extend?they are high drivers

"Low" is a relative notion in this case. "Low" could be 300Hz.

300Hz is extremely low for a compression driver. To go that low you should consider the phenolic diaphragmed large format JBLs like the 2482 or 2485. Unfortunately you lose the benefits of the extremely low mass and very high frequency break up mode of Be.

But then again, why are we discussing 300Hz and the two horns you mentioned above?

So, 2446 with original Beryllium diaphragm sounds the best?

Because if the driver has "something" happening at 300Hz, it means I will be fully operational at 500Hz with a 2350 at 12db cut-off.

Concerning the dimensions of the mentioned 2350 Horn,
especially keeping in mind the problem about "time delay" differences between mentioned drivers and lower frequency (bass or/end mid-bass) and high frequency (UHF driver) and keeping in mind that you will use 'in-home" environment, I suggest you to think about 2308 Lens + 2311 Horn, and with the frequency above, say, 800Hz, up to say 8~10kHz
