Outdoors there's one significant drop at around 39hz
Indoors there's a drop at 33hz a spike at 37hz and another drop at 42hz
Both measurements were made with mic around 20mm at cone centre
The lounge has wooden floors and wonder if that's causing the spike at 37k? floor is not particularly solid and could be a bit of a passive radiator.
But it's the 39hz drop outdoors that i'm initially trying to understand the reason, winisd indicated a steady rolloff as it does but the big dip I don't understand..
otherwise i'm happy with the frequency response measurements; for mid and highs both pretty flat in their respective ranges,

then govts can do the same to cigarette companies who add nicotine to their product.
Raising revenue is not an excuse for allowing manufacturers to use addiction to sell product.
Imagine the public outrage if supermarkets put addictive chemicals in meat or vegetables.
