The CRUNCH GTS series offers top sound quality, good efficiency, and easy installation. The impressive performance is partly due to the use of expensive Y30 magnets, which outperform some visually larger models despite their smaller size. Additionally, the GTS speakers are up to date: the centering spiders are further ventilated, and in the component speakers, an additional pole core drilling provides even better cooling. For the diaphragm, the developers opted for a polypropylene version that delivers the best sound results. Thanks to the linear frequency response of the speakers, it is possible to use very small crossovers, which are separately designed for the tweeter and woofer.
