I have always wondered why some people speak so strongly AGAINST powered towers... The main argument I hear is: "you place your speakers to optimize them for the high and mid frequencies, but you cannot place your speakers to optimize them for the low frequencies". Why do I find this argument problematic? Well...you can say this about ANY speaker which extends "relatively" low, and not just about powered towers. So--using this argument--if you are critical of, say a Def Tech bp2000TL, then why not be critical of a Paradigm Studio 100, NHT 3.3, Dunlavy SCIV, Wilson Watt Puppy, Revel Salon, etc etc etc? It is not often when I hear people mention the ADVANTAGES of powered towers. With "well-designed" powered towers, this includes: --virtually seamless integration between highs/mids/lows which can be controlled by the manufacturer. --very deep bass response relative to most other non-powered loudspeakers (particularly in the price range) --"stereo" bass (some people prefer this with music). --bass volume can be adjusted separately for each speaker. --can be crossed over relatively low (compared to non-powered speakers in the price range) when used with an external sub (the external sub need only handle really low frequencies, say below 40Hz). --a near full range speaker which works very well for formats such as Super Audio or DVD-Audio where bass management is apparently bypassed --the built in subs generally make these powered towers easier to drive then other non-powered speakers in the price range. --a great option for those who would rather not have an external sub in their living room. So in conclusion...certainly adding a quality external sub can improve performance (particularly for the very low frequencies)...but a well-designed powered tower certainly has many favorable points and should not be so quickly written off, IMHO.
