Radian 475PB Driver

Not positive yet but I do the the cut-off for the horn is 600hz so I’m thinking in the 1kHz to 1.2kHz range.

If using a first order XO that is about as low as I would go.
2nd order you might be able to do 850

@MrEd now you have done it. I ordered a pair of paper copper lites to compare with the new GPA phragms i got 9 mos ago.

When I get my 414/32 build done...

Damned Enablers. Some local hifi garage sale money was a 🔥 in my pocket.

I have been succesfully experimenting with a B&C DE250 w a polyimide dighrahm... which are also around $100/ea. I've been listeing to that on Trieu's WE 12027 horns and have yet hear these on my 32 horns, so propbably shouldn't conclude anything yet. But the 12027 is more imediate, so, anything unlikeable would probably show up in spades... whereas the 32, I think, is more forgiving. I hear nothing but goodness with this combonation and can listen long into the night without any signs of fatigue. One day I'll swap the drivers and horns and will have a more defitnive opinion but overall both sound really nice. And did I mention how cheap they are?

Thanks for sharing your positive reaction to the B&C DE250 which I've been tempted to try.

FWIW, I briefly had a chance to listen to the cheaper and smaller brother, B&C DE10 + the Lycan3R aluminum WP12024s crossed around 3-4 kHz and was quite impressed by the lack of harshness, very smooth and airy overtones. I've tried a couple of modern drivers that induced fatigue even when crossed that high.

J-Rob also said good things about polyester diaphragmed B&C drivers (#46).

I have a pair of the DE10 and they are definitely not harsh or edgy.

I’ve been using polyimide diaphragm DE250 clones on SEOS-12 horns in my Zephyrs for about a decade. They’ve been doing living room duty for the last four or five years. Highly recommended.
