I've heard several modded K-Horns. (511B mid horns, higher quality drivers, different networks, etc.) I've also heard A PAIR of Jubilees in different locations with A LOT of different amps. We got to play with these quite a bit at the factory. We also made direct comparisons at the factory, we had K-Horns in the same room. I'm just saying maybe you should hear the Jubilee before you form an opinion.
