    RS Kappa 3

    This project is based on a pair of RS 1001 speakers: tweeter EMIT automotive small sized and 4.5" woofer newly refoamed that originally has been a Crescendo series midrange. I believe that the reverse dome dust cup helps to achieve a better, more uniform bass emission.

    Renaissance 30 & 30 Mk II

    The Kappa Rear (very rare to find) cabinets are shaped similar to Renaissance series but the drivers are not the best, so I replaced them with a better 5" 1/4 drivers and EMIT K.

    What? Plastic? Chinese? 9.9 euro? YES... I was zapping on eBay... I came across this cheap nice piece of plastic... I though to get a pair of these to make two little monsters... the original "sound" was ridicolous with its economic 3 W full range driver... with a FALSE tweeter shaped plastic... after 5 days the transformation was completed : 12 W RMS, 2-way micro desktop passive speaker set. 310 grams each. They measure 76 x 123 x 84 mm.
