long and short of it

[Chef Henry]

Is the HF91 used in the Olympus equivalent to the 2307 used in the L200, or to the long version used in the L300? What are the advantages and disadvantages of the long v. the short version?

basic idea is that the "long horn" 2312, can be crossed over at a lower freq than the 2307 horn ...
you can do an advanced search, but here is the basics ...

H91 = 2307 (1" throat)
H92 = 2312 (1" throat)
H93 = 2311 (2" throat)
L91 = L92 = L93 = 2308

HL91 = 2391 = 2307/2308 (1" throat)
HL93 = 2392 = 2311/2308 (2" throat)

The H91 and H93 are for 1.2 kHz and above (although JBL did use them at 500 Hz and 800 Hz in some systems if only because there was nothing else laying around at the time to use instead).

The longer H92 is an 800 Hz horn.
