  1. 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??🤔
  2. 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.
  3. 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!!🙏
  4. 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.
  5. 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🤔
  6. 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??
  7. I have a pair of RF-83 which are rated down to 29 htz, and have serious bass peaks in my room at 45 and 70. In my attempts to solve this issue I have played with tone controls, plugging ports in various combinations, fidgeted with position and other tweaks. The best solution I have found, that only modifies the bass 1000 htz down, is plugging 2 of the 3 ports in these speakers, the bottom 2 to be exact. When doing this I lower those room peaks but to my surprise, I gained bass from the 32.5 htz and lower. Sounds much better to my ears. I am confident in my measurements, I did them like 20 different times, different days, and they are consistent. Seems like a good solution with no apparent down side. Am I missing something???? attached image with 2 curves, one normal response and one with 2 ports plugged.
  8. Nice setup!! You have a DAC and a turntable going in analog to your 88A, so you your 88a is essentially your preamp and DAC. I have tubes on my Sunfire Tube preamp, and the dsp goes after that, then into a Sunfire 300 Two SS amp. Do you think it will add its own digital color after my tubes or is it very transparent?? I love my sound now but would like to do some room correction if it does not negatively affect my sound.
  9. Hello, I have been curious about the miniDSP with Dirac live, but I am hesitant to incorporate an analog-digital-analog conversion after my tube preamp. Logically it should eliminate the use of the tubes and it's goodness🤔. I know there is a question somewhere in there??? Minidsp after tubes: yes or no??
  10. Agreed!! I don't see myself replacing my RF83 or RF63 for these Forte II, but now that I have them dialed in they are truly magnificent speakers!!
  11. The correct positioning helped with the bass. I also change the speaker wire from 14 AWG to 11AWG, installed the Crites crossover upgraded caps, switched the crossover cable to the woofer from 18 awg to 14 awg. At the end everything helped, now I am really digging these speakers a lot!!!
  12. Position and correct cable AWG made a world of difference!! Thanks for all your help and guidance👍
  13. I checked all the settings, played with the position and all is good now. I think they were set to small and crossover at 80mhz default. They are sitting 6 feet from each other, like 10 inches from the back wall and around 5 feet each from their respective side walls. I am using 14 awg speaker cable now and tomorrow will switch to double 14 agw, effectively an 11 awg, maybe that helps a little the low end too. Will upgrade the caps and internal wiring to 11 awg tomorrow, lets see how that works out. Was maybe thinking of glueing a washer to the back of the passive radiator(apparently max 2.5 oz), supposedly this helps them dig deeper??? Got some Dynamat for internal damping of the cabinet and the passive radiator metal brace. Will play with the angle a little tilted up to compensate for how low they sit? All these upgrades and tweaking could work for the better or worse, but it sure is fun though!!!
  14. I didnt get to play alot with it today, just reset to factory default. Tomorrow will check because it doesnt make sense that a room could suck SO muh life from them. Thanks for the heads up!!👍
  15. Ironically, recording music studios suck for music listening!!!🤔
