Yes, it is okay to go with higher values, just never lower.
How can I tell if my Sony subwoofer is active?
Sony® receivers will send a simulated LFE signal to the subwoofer and the SW indicator will light up. Verify the subwoofer power cord is plugged into an active AC outlet and that the subwoofer is powered on. If the subwoofer does not have a power cord, then it is a passive subwoofer. In that case, you will need to purchase an active subwoofer.
