I have not heard those exact models of Raidho’s. I have heard the threes. The Benno designed Raidho’s (including actual 3 way designs) break in faster and work in more spaces. The 4s are big speakers and need a big space to be at their best. But they still need 250-500 hours of break in time and min, 3-5 feet in space behind the speakers.
The Borresens need 5-8 feet in space behind them (very much like Kaiser) and 500+ (Yes, three weeks of constant play) hours of break in time. Great speakers. Probably are better than the Raidho’s but you really need the right room for them to hear it. And those aren’t common.
If your room isn’t right, the Raidho’s will outperform the Borresens. If you have the right room, Borresen all the way.
