Speakers for a 12 year old Dj

[Calin]

Hi guys!
I am planning to buy a gift for a friend of mine, I already gave him a dj controller Pioneer Ddj ergo limited, he likes DJ'ing, he started playing forhis friends/class mates...he currently has a no name cheap little speaker and I was thinking to buy a set of RCF Art 735-A Mk4
Also, after a lot of reading and YouTube videos, I understood that he might also need a subwoofer...
Question 1 will RCF SUB 702-A II active subwoofer be to small for the 15"tops? / is it worth adding it? ( I chose this model because it's only 19kg almost any other sub is more than 25-30kg)
Do you think the speakers I am looking at are a good choice? Last week I almost clicked buy on a Mackie SRM650 pair
P.s. I am a complete beginner

Also got him a Mackie profx4 v2, I just need to decide on the speakers

15" tops are designed to be run without a subwoofer.
If you are running a subwoofer your tops should be 12", 10", or 8" since the subs are handling all the bass.
15" tops with a subwoofer not only sounds worse but adds extra weight and extra cost.

Ideally an 8" would probably sound the best but they aren't that common. So I would recommend two 10" tops with a 12" subwoofer or a 15" subwoofer.

BTW
The most common is 12" tops with a 15" or 18" subwoofer or subwoofers.

That is because 12" tops sound pretty good on their own. So for smaller gigs you don't need to take your subwoofer with you.
