I have both the P163s and the BS22-LRs currently. I prefer the BS22s but the P163s aren't exactly a bad speaker; the BS22s are just a
better speaker

The 163s only seemed to have a problem when played hard full range and compared to the BS22s, they don't have much more bass for being a much larger speaker with a larger driver. The 163s are not quite as detailed and sort of seem (not necessarily intentionally?) to perform best with a certain categories of audio, where the BS22s have been solid with everything I've thrown at them.
