High Efficiency Speaker Asylum

I have a pair of Dunlavy SC1 driving off of a pair of Tripath 1024, 10 watts maybe. They sound graet, no bass. What are your thoughts on the big Dunlavy's relative to big Altec's? There is a pair of VI's out there for about 10K?

Hello
Dunlavys are NOT hi-efficiecny speakers.
The published Dunlavy spec of 91 efficiency is misleading. Its hard to drive and it is very sensitive to amp choices. If you try 9 different 100+ watts solid state amps, you might find 1-2 amp that are compagtible with the Dunlavy. Also, the
Dunlavy are very sensitive to room placement and like 90-120 degree V between them and listener. The Dunlavy IV & V are modern classics and are among the best modern speakers (no experience with VI but exepect something similar). But its hard work to bring out its best . Once it is dialed in with right amp and right placement,
expect a neutralish sound with lots of clean information. Its also quite musical. The crossover is outstanding and its hard to hear the crossover points. They excel at unraveling the intent of a musical composition. With the wrong amp and wrong room placement they will sound
dead and uninvolving. However, at their best, they will NOT give you the effortless dynamics and free
flowing energy of hi-efficiency systems.

  Munna, good post. Your description rings true to my experience with the big Dunlavys.
  
  I especially like your description "...the effortless dynamics and free flowing energy of hi-efficiency systems." Well put.

Never heard them Jim. But being as they're the kind of speaker I don't hold with I reckon I wouldn't like them even if they sounded great.

  The 1.0's image like a mother. Unfotutnatly with 5" bass drivers they ain't got no bass. I suspect that the VI's might do it.

    Jim--If you want that robust and clear Altec sound and that imaging thing I suggest you listen to some 604 or 605 Duplexes. IME they do the imaging thing very well; lots of depth and width that extends past the speakers themselves and sometimes wraps around behind you. Spooky sometimes listening in the dark.
    
    This effect is dependent on the recording.
