2 way, which are the best designs?

OP, if you’re used to an active 3-way there’s no way back :-) Standmounted 3-ways are for me the most interesting speakers today.
Try the ATC 50, 100 or 110, Quested v3110, PMC IB2i, IB2SE, Kii 3, Dutch & Dutch, Sp Acoustics, Geithain or similar. Quested being a little (100 pounds!) favourite for me..
If you still want a 2-way you have the active ATC20 and the Quested v2108. Any 2-way passive or active will naturally need subs if you'd like to feel the bass.

D2girls, i listened to K2 9800 i think they were named.
I liked those, but to big in my room. Part from that, i could never afford those.

Gosta, well, i have had PMC IB 2S and those i liked.
I got a good price for them, so i sold them.
But perhaps you're correct saying i'd better stick to a 3 way design.

Folks don't seem to bother to look what MM 27 really is.

For those that read this, it's 2*10´ bass drivers and 2*5´mid/bass drivers and 1´soft dome tweeter and they are monitors.

So anything smaller than an 8' driver is not going to happen.

I went with studio monitors simply because "hifi" is too expensive.
Had Barefoot been deemed home audio toys, the price had been way up.
I spoke to Tony Gee (acoustics) about a custom build speaker like MM 27.
He told me right away, it's impossible to build anyting like that for those money.

Kenjit, if you think MM 27 are harsh, i wonder if you've heard the latest gen 2 and not gen 1?
No way gen 1 is too harsh. If you think so i don't know, but you simply must hate all hifi speakers and if so, why aren't you hanging at a DIY forum? 
I don't say this to be rude, i've probably owned 10+ speakers.
I can't keep count on everything i've heard over the 27 years i've been around. 
I suggest you look up studio monitors, the big ones and listen a bit.
Perhaps you'd get a view of what the best of them sounds like.

I should also say, i don't say anything to be rude. That's just ridiculous.
I've never understood those seeking forums to be a rude idiot.
I am merely seeking interesting ideas and to have an open mind is always good. It doesn't mean we have to agree on what others like.
But learning others ideas and preferences is no heavy burden to bear.

I hope you find your nirvana in your own design!
