Neighbor Complaining...

Is this a rental or condo? I would think no matter where and how you place the system their going to complain. If you just purchased then I would think a little renovation should help like sheet rocking over the wall with another.There was a tread on Audiogon just recently discussing this same issue. When your that close there is really no best solution when you have neighbors top to bottom. And the only best solution would be to buy a private home away from the crowd.

Toufu we never asked you the square footage not knowing it was a converted loft. I would say it's not concrete but sheet rock over old construction "wood and plaster". I gather the building is sprinkled and up to code, because lofts usually are not fireproof or have fireproof staircases. I only say it for you to make sure you have apt insurance and try your best to have all receipts.

Bostonbean I happen to know something about old loft construction and fires.I worked in this area in NYC for over 21 years, and lofts can be fire traps. That's why I gave this advice.And Bostonbean you sound like your full of gas GEEEEEZZZZZ.
