Room acoustics

I have a similar L-shaped layout. Recently, I put a pair of ASC tubes next to the speakers that almost eliminated the low end scatter on one side of the room. They also look great.

Auralex Acoustics has some premo products but GIK seems more home
user friendly. It sounds like the bass control is the most important consideration....yes no...

Sadly you will find that getting 'better sound' will lead to a divorce. Chasing a WAF will always lead to compromises that will defeat your goal. Most audiophiles quickly realize that only an enclosed, dedicated listening room works, and even then to treat and tweak that room is an art, often taking years. So, accept your fate for now, give good headphones a try and be grateful for a happy wife who rewards you often for your kind consideration of her need to have peace and quite.

The enemy of really good is the pursuit of perfection. If one wants a dedicated sound room and can enjoy the satisfaction that comes with it then go for it. Personally, I don't want to spend years tweaking and building and refining a room to make " the perfect man cave" (not that there's anything wrong with that). But I am confident I can learn how to take an acoustically challenged living room, dramatically improve it's sound management, add some very good...not the best...components, and get some very satisfying and fun listening / viewing pleasure. I also think I can do this without loosing my wife:-)

Okay, plan B. Call Jim Smith of 'Better Sound' and have him come by to do his 'thing'. Most audiophiles do not believe in 'professional help', like Jim. Sadly. Seems few take advantage of Jim's forty years of experience, even those with $100K plus systems. They are the types that do their own brain surgery.
