The CRUNCH GTS series offers top sound quality, good efficiency, and easy installation. The excellent 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 ventilated, and the components feature an additional pole core drilling for even better cooling. For the diaphragm, the developers opted for a polypropylene version that delivers the best sound results. The linear frequency response of the speakers allows for the use of very small crossover networks, which are designed separately for the tweeter and woofer.
