Best Small Efficient Speaker for Office or Sm Room


I'm thinking of putting together a simple system for an office. A nice receiver or intergrated amp with tuner and CD player with small speakers placed on office furniture or speaker stands. I'm looking for a speaker that sounds good with very low power (25-40wpc) and at low listening levels. Another important part of the puzzle is that I don't want to spend more than $250 per pair used. Looking for some good feedback here. I'm open to any suggestions.

NHT. You can pick up some nice NHT's for very reasonable price (used). However, I would go for a fuller range NHT than the Superzeros. I own a pair of Superzeros and would not put them in my office. I also own B&W N802's and have run smaller B&Ws, Thiels, but for my office it's an NAD integrated and NHT speakers. Excellent at low volumes where they still seem to do the good stuff right.
second the Axiom M22Ti. I have been very happy with them driven by both a flea power zen amp and 300B tubes SET amp. Only missing is the bottom end.

A pair of used Tannoy Mercury M1s costs about $160 used.

I think Superzero's are too bass shy.Try the ones.I have recomnded B&W 302's too freinds and use them on my all in one office set up.They don't have the bass the 303's have but are much cleaner and bright which I like.Really interesting technology went into them with a back panel with molded pyramids to break up standing waves.Last the cheap Triangle bookshelves (Titus?) get very favorable nods and are very efficient.Letus know what you got!

I think they would also be fine for a small amp in an office, but just to let you know that the later mentioned B&W DM303 which replaced the DM302 is not as efficient (88dB).
