Hi Ricardo,
I know the Radiance 1's well 😉 I've not heard the Paradigms but purely going by "on-paper" figures I'd say they are probably a better bet than the Radiance 1's if you're only listening to house music - simply by virtue of them being quite a bit larger with bigger main driver as well.
The Radiance range was largely designed to time well and be very punchy/percussive without harshness so they are usually an exciting long-term listen and can handle plenty of power, but when it comes to all out thumping bass then timing only goes so far with house music. Size of room and partnering equipment are also factors of course - the best way to compare is to get a demo if possible! Most dealers/distributors we use would be able to sort something out...
