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 ...Originally Posted by Chef Henry
you can do an advanced search, but here is the basics ...
http://audioheritage.org/vbulletin/s...ight=2307+2312
2ch: WiiM Pro; Topping E30 II DAC; Oppo, Acurus RL-11, Acurus A200, JBL Dynamics Project - Offline: L212-TwinStack, VonSchweikert VR-4
7: TIVO, Oppo BDP103D, B&K, 2pr UREI 809A, TF600, JBL B460
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.
