Most speakers are fairly good at resolving details in the mids and highs.
Very few speakers move enough air for accurate body. You need 2 12" drivers or a 15" driver for the mid-bass (200hz) if you want it to have the weight of real instruments in the room.
The immediacy of real instruments comes from high efficiency.
I've never heard drums sound accurate out of a speaker with less than a 100db/1w/1m efficiency rating.
There's a relatively small list of speakers that fulfill this criteria.
