Would you choose 1 ou 2 subwoofers for a stereo set?

Would you choose 1 bigger sub or 2 smaller ones?

For a living room 6 x 8 meters (speakers on the smaller side). (3.5meters high)

Mcintosh MA9000 + BW802 D3

I listen mostly to digital audio (DAC / Streamer)

Looking into 1 JL Audio 13" or 2 JL Audio 10"
