RFT (Rundfunk -und Fernmelde-Technik) Acoustics model 'K13 Profil' studio monitors sale. Made in the GDR (East Germany) before unification around 1980. Nice sounding bass reflex bookshelf speakers for everyday usage. While RFT offered a number of different models, the K13 are now considered their best. Sports an eight inch woofer with rubber surrounds and an one inch "eyeball' dome tweeter (very rare & cool :). Solid & heavy construction, with a rather sophisticated crossover network (for a two-way speaker) that will flash a red LED light if pushed to hard. Rated at 100 watts RMS each. The dimension are 8"w x 11"h x 8"d each. They weight in around 35 lbs total. Used, but in nice condition.
