Compare JBL 1,5" drivers

[baldrick]

Have anyone done some testing between differenet 1,5" JBL drivers?

I'm thinking drivers like 2447, 2450SL, 2451, 2452, 2453 and 476... Do they sound/measure pretty much the same with the same diaphragm or is there any real difference?

I did compare a 2452 and 2450SL/2451 with the same diaphragms, and found the 2450SL/2451 was superior with more realistic dynamics.

User notnyt over at the AVSforum has tested several of these starting at post 121 and going to post 141: http://www.avsforum.com/forum/89-speakers/1925586-just-purchased-pair-jbl-4722n-speakers-121.html

On my JBL 4722's biamp version, I use the 2453H-SL and they sound and measure better than the stock 2432H.
