I think the term monitor is not good and except for pro purposes they should drop nearfield, midfield, etc
Coincidentally, I was just at a customers yesterday who is down sizing and due to WAF is not taking his Thiel towers with him. He has been demoing book shelf speaker but has been hesitant as he doesn't think a book shelf speaker can fill his room with sound. Others on forums like this keep telling him if you sit more than 6 feet away you need big speakers. We told him except for bass a bookshelf will be fine and might want to supplement with a small sub. He said he has been reading and they are only good if you sit close.
We wanted to him to hear some Genelecs but he said he would definitely not go with them due to aesthetics. We said why don't you try these Kali that we have in stock here and see if bookshelves will work for you. So, we brought him a pair of IN-8s with WS-12 sub. He was shocked. We played material for 3 hours with and without the sub and we let him keep them for a while even though we know he will go with someone else. The KH120 and KH150 he would consider. He is looking for speakers in white.
He was shocked, he couldn't believe bookshelves would work. They played louder than he would ever play and we were sitting 14 feet away. He will never come close to reference level. For certain material he said it was fine without a sub but for other material he appreciated it. He would definitely go with a small sub but is fine with bookshelves now. He also likes the Kali better than his Thiels which surprised him and me.
His search will continue and I recommended some brands and models for him to try. Where I work is not a retail store so we don't do a lot of demos. We can order speakers and equipment but don't have a lot in stock. We are not offended if he buys elsewhere.
Anyway, all the talk that you need some large speaker if you sit more than 2m away is doing an injustice for people that will never listen loud. I understand why the pro market labels near field, etc. But, in reality there is nothing different about a bookshelf speaker and studio monitor and either is fine for the home depending on one's desires.
