whell Posted May 25, 2002 Share Posted May 25, 2002 When reading and/or responding to this post, please calibrate your frame of reference, since my "electronics education" is pretty limited. That being said, I am cobbling together a second system with an old Kenwood KA 9100 integrated amp as the centerpiece. I have an old pro amplifier that I would like to use to drive an old passive sub that I've found, and connect the old amp to the pre-outs of the Kenwood. Don't want to send the full range audio signal to the amp, just, say, the bottom 60 - 80 hz. Can I build a simple, non complicated crossover, and connect it between the Kenwood's pre-outs and the old amp's inputs? Given the nature of this system, I don't want to spend alot of cabbage on this if I don't have to. Thanks for any suggestions on this! ------------------ Mike - Livonia, MI Klipsch RF-3 L/R Klipsch RC-3 Center Klipsch RB-5 rears HSU Research VF-2 Sub Marantz SR-19EX receiver Marantz MM-9000 Amp NAD T550 DVD Adcom GCD 700 CD Quote Link to comment Share on other sites More sharing options...
JohnA Posted May 25, 2002 Share Posted May 25, 2002 Get a pair of Harrison Labs F-mods. They have a web page. An F-Mod is designed to plug into phono jacks and deliver a 12 dB slope for high or low pass. They are probably $10 a pair.

whell Posted May 26, 2002 Author Share Posted May 26, 2002 Oops, you lost me, mdeneen. Again, my electronics grounding is not the best. Is there a diagram or schmatic that you could refer me to? ------------------ Mike - Livonia, MI Klipsch RF-3 L/R Klipsch RC-3 Center Klipsch RB-5 rears HSU Research VF-2 Sub Marantz SR-19EX receiver Marantz MM-9000 Amp NAD T550 DVD Adcom GCD 700 CD Quote Link to comment Share on other sites More sharing options...
whell Posted May 28, 2002 Author Share Posted May 28, 2002 I think I've got it now ( a picture is worth 1000 words, I guess!). Last question: do I modify the incoming cables (to the amp) for both the left and right channels as shown in your diagram (since I've got 2 channels into the amp)? ------------------ Mike - Livonia, MI Klipsch RF-3 L/R Klipsch RC-3 Center Klipsch RB-5 rears HSU Research VF-2 Sub Marantz SR-19EX receiver Marantz MM-9000 Amp NAD T550 DVD Adcom GCD 700 CD Quote Link to comment Share on other sites More sharing options...
