Bookshelf Speakers that have to be up against the wall

Is there any room at all behind them?  I had a lovely pair of bookshelf B&Ws that started me down the audiophile path.  Powered by a McIntosh 252.  It was a great set up.  Sill own the 252 that powers a pair of B&W 804 D2's.  Sounds lovely in my office.

First I want to say thank you to all of you. I am going to try the cheap route first and plug them, I do have a sub, but it’s an older velodyne model right now.  I can move them a few inches from the wall and will see how that goes. I will then go the route of checking out a few of the speakers mentioned. Luckily I live near several high end Best to you all.

@deadhead1000 I had the same problem. I had to put the speakers with a rear port close to the wall and the sound was terrible. I simply put a large amount of cotton inside the ports and the speakers sound superb. Try it. It's cheap and effective. I didn't experiment with other materials and I can't think of any other material doing the same job so well done. Common cotton is great. It transforms a speaker with a rear port to a speaker with no port. I forgot to tell you that the speakers were cheap and I used them in the kitchen. Maybe this trick is not suitable for serious listening but give it a try and see for yourself. Cheers.

Guru QM 10-2 were really fun speakers. Great midrange and bass that far defies its size. Made to go against wall or in corner. One of the few speakers I regret selling.
