Speakers for a newbie

Hi all.

Can someone please give me some advice on speakers?
It's my first setup so I bought some old gear. I want to improve little by little.
In my first setup so I'm on a budget. Any ideas on a sub 500 Speaker set?

My amp is:
Mcintosh MC7100

Preamp:
Rotel RC870

CD Player:
Rotel RCD-965BX

Thanks a lot!!!
