Володя ,прежде чем советовать ,почитай зарубежные форумы о попытках модернизировать кросс ,выбросить оттуда электролитические конденсаторы и резисторы ...все как один отмечают ужасный звук после этого ..инженеры роджерс понимали ограничения и сделали все как положено ,а они явно поумнее нас с тобой
''I quite often receive emails asking about moddifying these speakers (and indeed, others on this site). From direct experience, I would advise caution. I tried changing the two electrolytic capacitors for expensive polypropylene devices, and the results were horrible! The midrange glare mentioned below was made much worse, and the original caps went back in a few weeks later!

Electrolytic capacitors have well-known problems and limitations, and the designers working at Rogers back then were talented and experienced engineers. Quite simply, these limitations were accounted for at the design stage, and substituting "better" components will upset the balance.

As for "upgrading" internal wiring, before doing this try to work out how much standard-quality copper wire is used for each inductor in the crossover, not to mention the voicecoil!""
