Just moved to an apartment need speaker suggestions

Telling the OP that he/she NEEDS efficient speakers is just way too subjective an opinion and ends up limiting the choices. It's also confusing and therefore possibly counterproductive for the OP because it's in direct conflict with many of the good suggestions here.

Also, did you read my comment about the Quatros? This PROVES your efficiency statement to be incorrect in general. I know the Quatros are out of the price range, but something like an inefficient $1500 ... whatever (see suggestions above) + a powered sub would not be.

Again regarding the Maggies, as has been stated a few times here, they will only be *right* for an apartment if you can place them well away from the rear wall. 

Neat Motive SX2 is an excellent speaker.  It has a small footprint and have a much fuller sound than their stature would suggest.  Their reflex port fires down through the plinth so they can be placed anywhere which makes them ideal for apartment living.

A lot of good advice in this thread.  I think the Reference 3a would be an excellent choice and so would Neat speakers (talk about an under-rated line of speakers).  On the higher efficiency side, the Tyler Acoustics PD15 is another candidate.  Never heard the JansZen, but, some electrostatics would also be quite good.  Personally, I like the old Quad 57 because it can play soft and the limited bass response would be apartment friendly.

I know that it is very much a rough generalization, but, a lot of high efficiency speakers ARE very dynamic sounding, particularly at lower overall volume levels.  I find the full range single drivers to be extremely dynamic, but, most have very limited bass and a very pronounce upper midrange peakiness as part of the bargain.  The more reasonably balanced high efficiency horn systems have the big negative of being very expensive and impractical because of the room that they take up.  Because of the ability of horn systems to sound amazing at low volume, you can find crazy pictures of huge systems taking up almost all the space in Japanese audiophiles' tiny apartments.

Funny it took me until now to realize this: I’ve been researching DeVore Gibbon 8s for the last 3 weeks, and often came across an opinion that these are right for small rooms. I think the point there is that the bass isn’t big enough to really call it a full ranger, but maybe it’s enough given the right space? I bring up the DeVores because of the way the drivers are well above the floor. This same design is employed by some ProAcs that I see for sale here. The ProAcs are not known for being light afoot with respect to bass, but again the drivers are well off the floor.

I think it’s worth looking into this design and researching what people say about it. It doesn’t have to be DeVore or ProAc specific, rather what are people’s experiences with respect to similar designs?

By the way, I bought some DeVore Gibbon 8s arriving today. Unfortunately they won’t be going anywhere soon;-)

I was referring specifically to the ProAc response 2.5s above, but I believe other ProAc models employ a similar design.
