** Für solche Lautsprecher mit diesem Aufbau und Bestückung würde man heute locker 2000,- € pro Lautsprecher bezahlen.

** Much too bad for party speakers, although they would serve their purpose very well.
** Zum besseren Verständnis habe ich zahlreiche andere namenhafte High-End Lautsprecher hörbar vergleichen können z.b. den YAMAHA NS-1000 oder ONKYO SC-901 als Maßstab und ich war jedesmal von den LS-990 erstaunt.

For such speakers with this construction and equipment you would easily pay 2000,- € per speaker today.
** Fazit zum Vergleich: so gut wie kaum klangliche Unterschiede in den Eigenschaften festgestellt. Also selbe Liga wie oben schon im Vergleich die benannten Yamaha NS-1000, usw.

These KENWOOD were already produced in Japan between 1977 and 1978 only in small numbers.

The 100 Watt at 8 Ohm are real Watts and can also be driven by a tube amplifier. By today's standards, that would equate to about 200 watts of power.

For a better understanding I was able to audibly compare numerous other well-known high-end loudspeakers, e.g. the YAMAHA NS-1000 or ONKYO SC-901 as a benchmark and I was always amazed by the LS-990.
 +
Conclusion for the comparison: hardly any differences in sound quality. So same league as above already in comparison the named Yamaha NS-1000, etc.
 +
** Unfortunately, it will be very difficult to find them in good to very good condition if you go in search of the rare LS-990. I can only recommend the Kenwood LS-990 to everyone!
