Anyway just suggesting this because I think many people dont know they can use this method to try to improve the combined sound quality of their subwoofer and speakers. After adding 1.2m to distance setting I found bass louder and even had to reduce subwoofer levels in avr also. Now it sounds perfect to me.
Please try it bros and let me know what u guys think. Add 1.2m to your avr subwoofer distance setting. Not happy can just change back. At least try before increasing subwoofer volume or thinking you need to spend more money to buy bigger or better subwoofer.
