Top Technology has its price. But there must be solutions for applications which require a good sound at reasonable costs. For this we have developed the Gradient Select Series. We have proven with many speaker kits that those can be top in speaker sound. These speakers operate on a proven technology and without unnecessary extras. Nevertheless, they are technically up to date. They have characteristics that are not always common in this price range. Reliable, available universally and at 4 and 8 ohms. Gradient Select speakers have a very good price-performance ratio. Affordable loudspeakerdrivers without compromising the technical data and good quality. The line consists of a wide range of midwoofers and woofers.
