I know the old (2446 and before) drivers: they have 4 mounting screws on 101,6 mm bolt circle.
But on the newer ones, the spec sheets are confusing.
Do anyone know the bolt circle diameter for the
2450
2450SL
2451
2452 ?
Just trying to figure out which horns fit what driver.
Best,
Espen
A quick 'Google' on each of these reveals that the 2450 is a 50mm 2" diameter throat Compression Driver fitting 2380 Series & 2360 with adapt.'s..
I think [as in don't quote me] the SL model sported a coated diaphragm but same motor...
The 2451 is a 38mm 1 1/2" dia. throat on 114mm bolt diameter fitting the 2350 Series Horns
And the 2452 was a 1 1/2" dia. throat with a 3 1/4" (3.250") 82.55mm dia. bolt mount, used in the VRX Series - Line Array speakers...
Usually a Google search and look for the [PDF] Specification Sheet or Technical Manual will reveal lots. Look at the Response Curves and what they are using to get these curves. Either the 1" testing tube which will 'equate to' or on an actual horn. Check them out!

Am posting a group picture tonight showing ALL of these models and variations for reference.
Some of the above post is incorrect / incomplete..:(
