  1. Hello Brian, hope all is well. You still have those RF-83 drivers laying around. I am interested. Thank you
  2. I highly recommend it, its also a lot of fun. Here are pics of the new crossovers, and the old one for comparison, and the interior bracing. Even though it looks smallish, the bracing really made big audible difference, that extra support really tightened things up, I was surprised. Next step is to remove that foam and line all the interior walls, top and bottom with NoRez. (Don't pay attention to the finish, once all upgrades are done there is some tiddying up and beautifying work to do!!)
  3. I finally ended up building new crossovers for my Klipsch RF83, with new upgraded parts with same values, from GR Research, and I could not believe the difference that made. My speakers were practically transformed for the better. Not only to my ears, but the measurements proved what I was hearing. This motivated me to continue with bracing the cabinets, changing internal wiring, just ordered NoRez for internal damping and ordering pure copper binding post, and I am sure this will contribute even more. The sum of all these parts should make a considerable difference for the better, I hope!! I can't stress enough the impact of upgraded parts for your speakers. It is an affordable difference that could have a huge impact. Try it, you won't regret it. And if you can't hear a difference, at least you learned how to build crossovers and got the doubt out of your system!! The RF83 is a much better speaker than I thought, I am very happy with my "NEW" speakers!!!
  4. But would it be possible, I won't short anything out if connected directly through the inputs?
  5. Hello community!! Does anybody know if w=using the left and right inputs in the RSW-10Ds, can you daisy chain them?? I ask because in the RSW-15 the left and right inputs and outputs are all interconnected and can be used indistinctly. Thank you
  6. Agreed, very tough to improve if they don't receive the whole speaker. Fun project thought! I would just like to see how good these RF83s could get if you remove the targeted price approach and just make it the "BEST" you can, granted using the same box, woofers and horn. About the smaller speaker I was thinking on going on an open baffle style speaker from GR Research, seems like the direct opposite of the RF-83s. Will look into your suggestion as well and compare which gets the honor of the "MAIN" system and who does office duties!! Thanks you
  7. Thank you, will send this to Gr Research and see if they could go on that.
  8. Trying to send them out to GR Research but the lock down in my country prevents me. Trying to buy one to have it shipped to him directly and no luck. Does somebody have the schematics so I can build them, like Alexander suggests??
  9. Thank you Moray for your help, they are out of stock and won't be getting more. Any other suggestions?
  10. Hey John. I want to upgrade them with better parts, connectors, wires, ect.. Need to buy one and have it shipped to GR Research to map and help me with making it the best possible. Also doing some cabinet damping and additional bracing. Let's see how they turn out.🙏
  11. Hello community, can anyone steer me in the correct direction to buying an RF-83 crossover. Thank you, Carlos
  12. Here are the measurements for the Forte II, no grills, tilted up vs flat on the floor. Measured twice and the results were consistent. Green is tilted up, orange is flat on floor.
  13. Will remove the tilt and measure again to see the response. They do sound better tilt up, when they flat the sound feels like it is "lower", like its under you. Maybe I'm just used to having the tweeters above my ears living with the RF83s?? I don't perceive any different sin base response, maybe its measurable but no appreciable? I don't have the correct risers to get them to the RF83s height.
  14. Thanks for your knowledgable input. I have been working the RF83 whole system for a while trying to get the response where it is now. It was boomy around 40 and 70htz, but plugging those 2 ports really tamed that and gave me a better base to work feom. It made them dig deeper too, to my surprise. I replaced the tubes on the Sunfire preamp for old new stock ones, matched and balanced reflector 6h23p-eb/6922 Premium help the mids and does'nt push the bottom end, very highly recommended. They are magnificent speakers that need a little work to get them where you like Not the final result, but below is a comparison of the RF83 with the ports plugged and without.
  15. Thanks Bill!! I have tried all different combinations with the RF83 to control that bass, port plugs, different positions, bass and treble controls, etc... and this is my best response so far, will continue to mess with it, it's part of the fun. Is this typical RF vs Heritage behavior???
