If I wanted a similarly-sized passive speaker, with a similar, well thought-out engineering basis behind it, I would definitely seek out the LS50. Particularly as good power amps are not hard to find. The LS50 looks a particularly well-balanced design and I'm sure it will be easy to drive - so you can probably get away with a good quality AV receiver and have a terrific system
Why are you sure they will be easy to drive? Their sensitivity is 85db and their impedance drops to 3.2ohms. This makes it significantly more difficult to drive than, say, ATC SCM11s.
Not really, ATM doesn't say what their nominal ohms are, but here are the specs - note the amp power requirements. In any event neither speaker are going to work well with a 40w amp are they??
Drivers :
HF 25mm Neodymium, Mid/LF 150mm
Matched Response :
±0.5dB
Frequency Response (-6dB) :
56Hz-22kHz
Dispersion :
±80° Coherent Horizontal, ±10° Coherent Vertical
Sensitivity :
85dB @ 1W @ 1metre
Max SPL :
108dB
Recommended Power Amplifier :
50 to 300 Watts
Nominal Impedance :
8 Ohm
Crossover Frequency :
2.8kHz
Connectors :
Binding Posts/4mm Plugs, bi-wire
Cabinet Dimensions (HxWxD) :
380x211x250mm
Weight :
8.5kg
At the moment what?
Doesn't say 'nominal ohms'?? You've listed the nominal impedance.
Both have the same sensitivity. Both have the same nominal impedance. LS50s drop to 3.2ohms as listed on Kef's website. SCM11s drop to 4.8ohms as per stereophile's measurements, first hit on google for ATC scm11 impedance.
Anyway, I wasn't particularly after a comparison, just correcting an assumption which was wrong and putting the true figures in some context given the misconceptions people have about various speakers.
All academic when you're going to spend 800+ on either speaker - the truth is to get the best out of them you'll need electronics to match, and nothing less than 50w in either case.
