2408H vs 2408H-1 differences?

[300Z]

What are the differences between the two drivers? Why is the -1 a bit cheaper?
I've been trying to find any substantial info on these for the last couple of days but haven't had much luck. :(

I'm trying to decide which set of drivers to get between either of those, the BMS 4540nd or the B&C DE38, but I would like to know more about the JBL drivers before I make my final decision.

Thanks.

Leo.

Nobody knows? :(

I think, _but I maybe wrong_ that the "-1" indicates a ferrofluid cooled driver

At first I thought so too but the 2408H is considered the better driver used in the higher models... and it costs more, so I don't know. :/

JBL's part pricing is not a good indication of quality.

Though "-1" versions often are cheaper evolutions that are judged good enough for the intended application (2414H-1, 2404H-1, ...), but can be sonically inferior in some more general applications.

The 2408H takes its roots in the 2407H which was made by BMS (it really is a rebadged 4540nd) for JBL. Legend has it that JBL thought it was "overengineered" and built their own simplified version: the 2408H (and later 2408H-1, and for some applications the 2414H, and then 2414H-1...).
I never heard or measured the 2408H, but John W. tried both 2407 and 2408 (http://www.audioheritage.org/vbulletin/showthread.php?21202-Small-horn-monitors) and prefered the 2407.
I have compared the 2407H and 2414H here and the results are quite explicit (http://www.audioheritage.org/vbulletin/showthread.php?27551-2414h).

So if I where you I would pick either the 4540nd or 2407H over the 2408H.
