When is a 1/4" - 1/2" 2440 [or 2441,5,6] spacer needed?

[m8o]

Just wondering if the extension of the throat the short 1/4"- 1/2" amount helps or hinders any part of the frequency range, and when the spacer may be needed? Are there particular horns that hit the driver body and spacer needed to mount it? Or are there other reasons for it?

thanx,

In the likely event the '?' means "what the heck are you talking about" ;) and not "I don't know", I mean one of these (it should have occurred to me to post a pick sooner):

Would like to see what the other side looks like,,, could be an adapter,,Going from 4 bolt to 3 bolt mounting of drivers,, But i could be wrong,,, Cant see any sonic advantage.

I've seen this item come and go a few times with noone bid on it. Whoever bid against me, at least say "thank you" to me for pointing it out to you. :banghead:
