Huh,
Unless its dead flat its useless!! Throw it out.
(the 2446 is obviously different to the 4001)
Might need some optimisation.
I sold all my waveguides to guys that couldn't buy them from JBL Pro directly (overseas). And I don't have any 2452H's anymore either.I thought it looked quite good. It's perfect for someone with a 3 dB peak in their hearing at 2.2 kHz! And yes, it can probably be optimized for the 2446.
With the other compensation circuit I'll be curious if we feel the need for a little extra extension
at the "extreme" top, regardless of ones hearing ability out there, that extra there can really add
to frequencies one can hear, little bit of air and or shimmer could be wanted in those upper octaves.
I'll get to hear it soon enough and find out if it seems lacking..
I finally got around to digging this old post up: #27
Why are you still interested in these waveguides after I bent over backwards to get you a pair of H4338's? The H4338 is the best horn JBL has produced to date. I've not seen your project employing them. I wish I had the skills necessary to build a pair of wood H4338's.
