das design der 70er ist typisch wie zeitlos gut gelungen und für die ewigkeit sehr hochwertig aufgebaut!
 
  
allein das zusammenspiel mit meinem verstärker "auch" aus dem hause KENWOOD model KA-3300D harmonieren perfekt und der 30cm bass (massiv-alukorb) kriegt eine neue dimension ..

das klangfeld insgesamt ist sehr ausgeprägt und lässt keine wünsche offen, egal welche art musik sie aufspielen.

ihre größe und das gewicht volumen pro ls von ca. 27 kg unterstreichen das ganze nochmal. (nicht zu groß und nicht zu schwer) für räumlichkeiten ab 20 qm bis etwa 60 qm

für solche ls mit diesem aufbau und bestückung würde man heute locker 2000,- € pro ls zahlen.
 
diese KENWOOD ls wurden schon damals in japan zwischen 1977/78 auch nur in geringen stückzahl produziert und für den japanischen markt hergestellt.
 
  
die angaben 100Watt an 8Ohm sind echte watt und können auch mit röhrenverstäker betrieben werden und würde dem heutigem maßstab etwa 200watt leistung entsprechen.

also wenn man die ls-990 einmal hat der gibt sie mit sicherheit aus klanglichen gründen nicht mehr ab :)
 
ich habe das glück und besitze sie schon ca. 2 jahre und bin immernoch vom anblick und klang hellauf begeistert.
 
zum besseren verständnis habe ich zahlreiche andere namenhafte high-end lautsprecher hörbar in der zeit vergleichen können und ich war jedesmal erstaunt.
 
  
es wird leider sehr schwer werden sie in einem guten bis sehr guten zustand zu finden, wenn man sich auf der suche nach den raren LS-990 begibt, weil die ls wie schon angegeben in geringen stückzahl hergestellt worden sind.

Report[edit]

  • HIFI SECRET TIP! KENWOOD LS-990 speakers are true high-enders!

The woofers and midrange drivers are like the tweeters (JBL ring radiator) equipped with Alnico magnets!

    • The design of the 70s is typical as timelessly well done and built for eternity very high quality!
    • The interaction with my amplifier alone, "also" from KENWOOD: model KA-3300D, harmonises perfectly and the 33cm bass (solid aluminium basket) gets a new dimension.
    • The overall sound field is very pronounced and leaves nothing to be desired, no matter what kind of music they play.
    • Their size and the weight per speaker of about 27kg underline the whole thing again (not too big and not too heavy), for rooms from 20 sqm up to about 60 sqm.
    • Much too bad for party speakers, although they would serve their purpose very well.

For such speakers with this construction and equipment you would easily pay 2000,- € per speaker today. 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.

    • So, once you have the LS-990, you certainly won't give it away for sonic reasons.
    • I am fortunate and have owned them for several years. I'm still blown away by the look and the sound.

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.

    • 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!
