Suitable and recommended drivers for Nagaoka BLH

Hi all,
I'd like to change drivers on my FE103E BLHs and the only request is 8 ohm impedance and suitability, possibly with similar or better tonal balance, without harshness.

Many thanks for suggestions :cheers:
 
Absolutely. So are the alloy cone units for that matter. The cone material is neither here nor there as far as suitability for a general enclosure type goes. But it depends on which back-horn. They are not all created equal, and like any other enclosure, optimum results are achieved by designing a horn for a specific driver, rather than trying to force a drive unit into a box designed for something else. That being said, a bit of driver-rolling is harmless fun, if you've got the cash and aren't necessarily trying to extract maximum performance. 😉
 
Like said before, the horn should be tuned to the driver in it. But i replaced for someone the Fostex FE103En in his fostex horn with a Tang Band W4-2142 on recommendation of someone else to the owner. And that sounded a lot better (read: less bright and more bass) than with the original FE103En. It also went louder as that driver can take a lot more power. Maybe that can work for you also.
 
Thanks Nandappe. I always thought that Fostex blh project for FE103 was a Nagaoka one.
What supertweeter do you suggest for FF105?
:cheers:

It is a Nagoka/Olson style stepped horn, who designed it i cannot say,

FE1O3 SOL if you can find some. I may have a pair. FF105wk should work, you will have more bass. Only the FF225wk needs a superTweeter. There are some simple surround tweaks for these drivers.
