H,Tudor , welcome aboard.As you mentioned you have been a reader of these forums for a while so I'm sure you are ready for numerous suggestions that will then turn into arguments
I guess that's part of this crazy hobby we all love.
Your 40X40 room may cause a problem.
Being you live in Brooklyn, you have MANY knowledgeable and trustworthy dealers that you should visit.
Many of these dealers are set up in lofts so you can get an idea of speaker placement in large rooms.
Also you will hear what amp(s) work well with the new speaker or with your existing speaker.
Now that you read the forums go out and listen.
Have fun and the best of luck
