I am toying with the idea of running an analogue active 2 way crossover at about 90 to 100 Hz in order to free up the RS5's of bass load and split it off to my dual Rel T5i subs. Has anyone done this? The setup would be: Pre amp out > active 2 way crossover > above 90 Hz goes to power amps feeding the RS5/below 90 Hz running into the Rel T5i's RCA input. I love the RS5's but they are at heart a 2.5 way therefore the 5 inch mid is running full range into mechanical failure which just happens to coincide with the roll off of the 7 inch woofer (no crossover components between) and even the 7 inch woofer while ive seen claimed specs of 45 Hz i doubt it. I am hoping that by running the active crossover i will get even better sub integration as its not relying on guesswork blending the T5's crossover with the Regas roll off. Plus hopefully ridding the tube amps and the RS5's of sub 90 Hz freq they can operate more efficiently. PS: Please no comments saying Rel recommends speakon high level connections. I know, i am currently doing it but its not possible with the use of the active crossover which should offer greater improvement. I will be moving to bigger subs eventually so wanting to future proof a bit. Cheers.
