Whizzer in FLH (dumb question)?

[Cloth Ears]

Is it worth even considering using a driver with a whizzer cone in a front horn? Or will it just stuff up the high frequencies so much that it ain't with it?

Yeah, I guess all those folks that FH load Lowthers, various Fostex drivers, etc, would think it a pretty dumb question.

no problem, it works really well actually. Look at Bert Doppenberg's horns. www.bd-design.nl
The AER drivers are a high end version of an 8 inch Lowther/FE206/FE207

Big horns (like Oris) do not load the wide range driver all the way up to the whizzer operation range.

The whizzers are mostly on their own in that range.

I've just not seen one, so I thought I'd ask. Are there any pictures of these as I've only seen backloaded Lowthers & Fostex (with a whizzer, anyway). I'm think 160-200Hz, so about 2 feet in depth...

Sorry, couldn't resist since they litter the FR and HE forums, making them hard to miss. Anyway, I knew their proponents would post some good info. That said, they're not easy to get right, with the Azurahorn being the only one I'd recommend based solely on published design info.

BD design do some (the Oris range) which have a good reputation, though I haven't examined them closely myself. Currently, their site is undergoing a revamp, so details are sketchy.

Those Azurahorns do look rather impressive...

To get good treble with an 8" one needs either a low voice coil inductance or a whizzer. To be suitable for horn loading a driver needs a strong motor (high Bl, not so easily achievable with low voice coil inductance). The Ciare HX201 (Bl 6.1, Qts 0.34 according to HH) is a compromise that should work more or less in FLH, but I wouldn`t use it BLH.
