I was rather stumbled upon these speakers of Reckhorn when I was looking for a solution for my computer. Unusual appearance and a promising description - it seemed worth a try. I must mention yet that I listen to music via an 'old fashioned' hi-fi stereo system with perhaps a sophisticated amplifier and ordinary speakers. I have connected the S-15 to the loudspeaker group B; a comparison LS A / B actual rather confirmed my previous boxing in the highs and mids were both alternately quite well - the S-15, as expected, weaker in the bass response, there are just satellite boxes. The surprise came with the setting A + B, so both speakers with each other: 'boosting' it is true indeed: refresh, propel - the old Heco boxes fresh downright on, come more present, and the sound seems lifted and free to float in space , It's fun to listen to New's fun, on the thus obtained level playing estimated music - for low use a significant gain. If one has space for the extra pit. If you like the look. For me, the balls are on the Heco boxes. On fummeligsten and time-consuming way, was to put the Ständerchen for the boxes together; the six wire pens that you have to bring in the recesses of hard plastic triangles. And then attach the cap to protect surfaces. Well that only occurs once. The statement from the manufacturer Reckhorn, you've saved on everything that is not profitable to the sound, here gets a connotation that is not perhaps intended. The speaker cable are also clamped in accordance with this 'philosophy' only under a screw terminal, the polarity (+, -) is characterized in the loudspeaker capsule - ie deviating from the introduced red / white marking and certainly not banana. But so be it: Vielklang for low price. And for the computer I ordered a Bluetooth transmitter, which then served up this facility.
