Speaker placement, listener placement, furnishings, and room acoustics have about as much to do with it as the speakers you bought and more than anything else except the source material.
First reflections off hard surfaces like the side walls, wood floors, televisions behind the speakers, a wall or windows behind the listener, and hard coffee table will all contribute to a birhgter sound.
The overall reflectivity of the room at high frequencies will make for a brighter sound. A carpeted room with book shelves and drapes will be more pleasant than a brick-walled loft with huge windows and wood floors.
Aiming the speakers so they cross in front of you will reduce both the direct on-axis sound you're getting at high frequencies (but not at lower frequencies, with the speakers actually becoming omnidirectional in the bass) and intensity of the side-wall reflections.
