Hello,
Maybe someone have some experience to share or builds with "The Box 15LB075-UW4" I found them at thomann.de. T/S parameters are not promising, but the price of 55 EUR is appealing. Is it possible to find something better at this price and maybe there are more shops in europe that has a variety of speakers to choose from?
I have attached t/s parameters and one of the simulations I did. Is there a better way to do it then a .straight horn?

Entas,
Stoneeh's measurements in post #2227 show "The Box 15LB075-UW4" works well in the SS15 tapped horn design:
Single sheet TH challenge
Also works well in the smaller THAM 15 design post #687:
THAM15 - a compact 15" tapped horn
The 15LB075-UW4 Xmax is only 4mm, so don't expect to move mountains, but it has great sensitivity and does not require huge voltage swing, 50 Volts (Vrms) would be more than enough for it, and the performance to price level would be hard to beat.

That are PA subwoofer drivers, they are produced by Elder Audio and got cast aluminum baskets, they got a 75mm VC and the power rating not in the least exaggerated, for that price it's a steal. They work very good as subwoofer, I would not use them as woofers though. The Xmax of 4 mm is the pure mathematical method
(winding height - pole plate thickness)/2
Other manufacturers add 1/4, 1/3 or even 1/2 of that to it, so read exactly how their Xmax is calculated or do the math yourself when comparing them with other drivers with 5-6mm Xmax.
If you want 20 Hz, or really small subs, other subwoofer drivers are probably a better choice.
