2 entirely different animals there...the Heresy IIIs are extreme efficiency (99db) horns with no low bass (I own a pair and use 2 REL subs with 'em as they go down to about 58hz before the bass drops off...the bass they do put out is very accurate though), and the JBLs are 90db and more "normal" but twice as expensive as the Heresy IIIs. Heresy IIIs do seem to like boundaries as that reinforces the bass, and since they use horns they project away from the box to minimize room issue in the upper frequencies. Note that all of this requires listening to the things someplace as your ears are what matters, and note that at 4 grand for the JBLs you can look at a myriad of speakers that would also work great. Good luck!
JBL 100 Classic or Klipsch Heresy III?
Looking for any opinions on these two options being driven by a PrimaLuna Prologue Classic integrated in a smallish listening environment (approx. 13” x 14.5” end of an open floor plan space which goes right into a kitchen/minuscule dining area...Speakers have to go on the long wall and can have the benefit of close wall boundaries but not corners.). Listening tastes are all over the map with emphasis on mainstream Rock/Pop and Jazz/Blues but, on any given day, Stravinsky or Steeleye Span might be on the turntable. Thanks in advance.
