  1. 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.
  2. 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.
  3. 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.
  4. 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???
  5. I use a Sunfire Tube Preamp and a 300 watt Sunfire 300 TWO with my 83s and the really shine. The amp has a current and a voltage speaker outputs for different results. I connect the current output to the highs to get that tube like sweetness, and the voltage output to the lows for bass control. Don't be afraid to play around plugging different combinations of the rear ports to get the best bass results. Also try different distances from back wall. My optimum was 2 ports plugged out of the 3, around 2 feet from back wall and toed in pointing around 1.5 feet from my ears. Have fun!!
  6. In the middle of this world shut down, which I hope will be over soon if we all cooperate, I had the time to do a real comparison of my RF83 and Forte II. I have three systems, and have been living with them for a while now, but I never had a chance to compare these two speakers with the main system electronics and room. Here are my findings, hope it helps, or at least entertains! Electronics: Sunfire Vacuum Tube Controller Sunfire 300 Two amplifier. Current (tube like) and Voltage (normal) speaker connectors. Yamaha WXC-50 streaming TIDAL and HiRes music from server. RF83: Plugged 2 of the 3 ports, best bass output in my room. Connected highs to Current output and Lows to Voltage output, this yielded the best sound. Toed in and pulled out from wall accordingly to get best results. No grills for listening, make a noticeable difference in these speakers. Forte II: Crites upgraded caps kit. Sealed properly the box. Added a washer weight to the passive radiator. Toed in a little, less than RF83 though. Angled up about 1 inch. Grills and no grills very similar sound. Results: RF83 had more bass, a little looser, but definitely more of it and deeper. The soundstage was noticeably bigger, with much better imaging. The sound was just bigger and more of an event than the Fortes. At same volume the sound was a little lower, has to adjust to match the Forte. You don’t have to be in sweet spot to get great sound, you can walk around and still experience that live music feeling. The Forte has a livelier sound, more exciting maybe. The bass was a little punchier and tighter, but there was less of it, and did not dig as deep. Less imaging and more like a wall of sound quality, but much smaller soundstage than the RF83s. They don’t sound small at all, they sound big, but the RF83 sound bigger. When you move, or even stand up, the sound changes, it is noticeably better in sweet spot. I don’t have the technical knowhow or language to go much deeper or more scientific, this is just my general impression. When compared back to back they are very different, but none is better than the other, they just shine at different things. The Fortes are easier to listen to at lower volumes and can be used even as background music, the RF83 at lower volumes are heavier sounding, they need a little more volume to balance out. Don’t know if this goes in line with the RF vs Heritage general perception, but this is what it sounded to my ears, in my room. Set up properly and taking the time to correct for in room problems, they are both amazing speakers that can give great joy to most. Based on my needs, I am keeping my RF83 in the main system. Here are the measurements, maybe they could shed more light to those who can interpret it. The green is RF83 and the blue is Forte II. And a couple of pics!! Stay safe people!!
  7. Great, thank you for your help. It will be used instead of the RCA input jacks for the LFE line from the pre/pro. The input jacks got damaged and I only have the output jacks usable. Thank you for your help!!!
  8. Hi, are the line In rca connections just wired in parallel to the line out rca in the RSW15? Can I use any of them as a line in if needed?? By looking at the board it sure seems like it. Attached are a few pictures.
  9. Hello, I have an RSW-15 and two RSW-10D connected in my system for the past year or so, worked perfectly. I disconnected the RSW-15, and when a hooked it up a few hours later there was a strong hum coming from all 3 subs. I changed and switched cables around, changed outlets, moved things around and identified the problem comes from the RCA input of the RSW-15. As soon as I plug in an RCA cable to the RCA input I get the hum from any sub connected to the system, even if only the RSW-15 is hooked up.This happens on that sub even with the pre/pro turned off. The hum goes away if I apply a little pressure to the RCA plug. Definitely the RCA connection in the sub is causing this hum. If I touch different thing, like amp connections, sub plate or switches, turn on or off the pre/pro, etc... the hum oscillates. That 3rd subs connection is triggering the problem, but I don't believe it IS the root of the problem. Everything is connected as it was before the problem appeared. What could this be or how could I solve it?? Would this isolation transformer help??? https://www.amazon.com/Transformer-Eliminator-Blue-Jeans-Cable/dp/B00GG1PK5W Thank you!!
  10. I have not heard port chuffing, but I don't play them very loud though. Will experiment with all three ports plugged and see how they sound. Maybe I can plug all three and fill in the lower bass region with dual RSW-10Ds??🤔
  11. Hey willand. Yes, remove amp, cables and the two triangle controls/inputs on the outside of the box. The screen is not necessary, they have screens there to test.
  12. I like sealed subs so much I have 5. An RSW-15 and 2 RSW-10D stacked in my HT. Just bought two more and are out to service in Edwards Electronics and should receive them in a few weeks. I still don't know where to use them, but I got them and they are difficult to come by, jajajaja!!! Both of my 2 channel systems sound great how they are, maybe I will experiment with a 2.2 system and see how it goes. Thank you polizzio!!🙏
  13. Yes it did, they feel with more aplomb. That 15' passive radiator is magical, and it sounds alive even at low volumes which is just great!!! Some speakers you have to put the volume higher for them to shine, these Fortes are always "ON" at any volume.
  14. It seems that any combination of plugs used ONLY affects below 100 Htz. I am still getting a hotter bass than flat, but just below exciting the room to become boomy, better bass. And actually MORE bass below 32.5 htz🤔
  15. I agreed with you wholeheartedly that the right sound could only be defined by my own ears, too personal. Congrats on this cornwalls iii, they are incredible speakers. I have in my office system, which has extensive acoustic treatment, a pair of Forte II with upgraded Crites caps and crossover cables, sealed all possible air leaks and added 2.5 oz of weight to the passive radiator. These powered by a Sunfire Ultimate Receiver just sound incredible!!! I love sealed subs, I believe they give me better quality bass that the ported brothers. Thank you for for the pros and cons of BR design, there is very useful info in there to better understand the general principles. My confusion is why I gained bass below 32.5 htz??? Seems opposite of what I expected??
