After testing out my PDR10 in my loft theater (it usualy lives in the lounge), I've decided I need a sub up there. It gave more depth to the sound, and made my bass shakers feel more beleivable (they give a lot of shake!). I just happenned to be looking at What Hi-Fi, and saw the Hyperfi ads. In there I saw the Dali sub - it has 160w and seems good value. What Hi-Fi gave it a reasonable 4stars in August 2000, but I haven't read the review, so I don't know what frequency it goes down to, or what its shortfalls were. The PDR10 goes down to 27hz, and as I could hear the diference it made to my existing speakers which go down to 38hz, I know this can't be far wrong. So I need another sub like the PDR10, but with more power - I don't like running things at full tilt, cos they tend to go bang a lot sooner than something that is less stressed. The Kef 30b looked good, but only goes down to about 40hz and is only 100w, so I'm not sure if that willl give me the extra bass I need. Any other suggestions are welcome. Gary.
