Room treatment can be addictive

An alternative approach would be to apply both or either absorption or diffusion for peaky areas. If it is boomy, that indicates a problem around 100 Hz and below and there are few domestically acceptable diffusers that would accomplish this. At least for most home level diffusers, such as a QRD7 from a well-known manufacturer, the lowest frequency is roughly 350 Hz. Absorption in the form of base traps would perhaps be more effective in dealing with a boomy bass. Speaker and listening position can also dramatically impact the bass and should always be included in the equation.

Treatment rooms…. 10 days later.

“How do you fit the wife, girlfriend or partner in?”...

No one has answered this question so is it a good assumption that those with treated rooms don’t have any?

Alternatively, one might have a partner who is happy to devote a room to music and video. Kind of the ultimate in patience/indulgence/tolerance. She also told me to buy the car I had always dreamed of. Luckiest man in the world I am. 

We know who the boss is then.

Everyone loves their toys and should look after them…..Yes you are a lucky man

OP,

I'm lucky as well. While my partner gives me grief about my system... she is really supportive. She has seen me work for 70 - 80 hours for forty years and knows I earned my indulgences.
