I am using a RT3000p sub only for my side speaker with a Lexicon dc-2. I just found out from Ken that there is no high pass crossover on the unit. I have my side amp speaker outputs wired into the sub and then out to my RTA-11t's. Basically, I am sending full range signal to the sub and the speaker. How can I limit the fequency that goes to the speaker. I want any signal over 40 HZ to go to the speaker and anything under to go to the sub. The speaker/sub are too far away from the preamp to use any connection except speaker cable. Is there any way to do this? Thanks, Jeff

    Yes Jeff your in luck,
    you can pick up some 18x2 shielded with a drain for your line level run to the sub.Set your mains to small in the dc-2(nice I put on in last month)pick up some solder for the end's and your on your way.use the sub preout's any Y them.Interesting that you didn't complete the rt3000p's??

    Hello Jeff,
    It is difficult to use a series capacitor for such a low frequency, the value would be very high and would begin degrading the sound. For an 80 Hz high pass filter you could use a 330 uFd non-polarized capacitor with a .01 uFd metal film capacitor connected in parallel. This would result in a 6 dB/octave high pass filter.
    Regards, Ken Swauger

    Thanks gentlemen, but this stuff is way over my head. I ended up putting the Polk RT3000 sub in the family room (behind one of those fake ficus palnts, the wife didn't even notice it) and moving my Eosone sub (from the extra's closet) which has a high pass filter to my side speaker. It doesn't have nearly the power or low end, but it sounds fine. Now I have a Sunfire MKII for LFE, CS1000p for center, Yamaha YST-160 for one side and the Eosone for the other. Hopefully, I will upgrade the side subs soon. Thanks again
