  1. Yeah that’s a good comment Grant. I’d like to achieve the best sound possible in this room. And the middle is ideally where I’d like to sit as well. Might be time to contact an expert and learn some more in the process.
  2. Yeah - its a difficult one. After using an axial standing wave calculator I can understand it better. The area I can sit for best effect on the width axis is about 28cms left/right of the center. This gap is about 40cm at most. Move your head a little left or right and you don't hear some low range frequency. Move my head up a little higher - and I also don't hear some bass level frequencies. I might do the calcualtions and see how things work if everything was set on the short side of the room instead of the long side as it currently is. But this might be too much of a PITA to implement. This is my current plot in the new position with speakers and listening chair moved 28cms to the right. Taken with mic on the mic stand and no chair. Also with R only and L only speakers as recommended above. Average plot of all the tests as well. Tests where of center pos, left and right 10cm, and left and right 15cm. At listening height of 80cm. With L and R mic combinations. Question - why never use both L&R speakers at the same time to measure?
  3. Agree. Professional help might be next. Have been listening in the new position for two days now. It’s much better sounding in the sub bass region. when time permits I might move some more things around. everyones comments have been helpful. many thanks guys and happy 2020
  4. Cheers on the comments. in this room size - width wise I’m going to have a 40hz null and then a 118hz null in the centre. I can’t defeat the 118hz. Too high for subs. You have to move to get out of those nulls. But maybe a pro who’s solved the same could comment. the woofers on the horns are at the bottom. They are not subwoofers but they do go down to subwoofer frequencies. I’ve had a few subwoofers in the room. I was never able to get the results that I liked enough for me to justify spending the money. moving the seat to the right didn’t cost money. I’ve been listening in the new position for a while now. Some low end is more audible now. Everything else seems similar to the original position. question will be if the changes are worth the gains. More listening needed to decide.
  5. Thanks Dave - agree with you points. I've taken a load of measurements today. I'll take some more again tomorrow. I've managed to avoid the 40hz null. Can't sit in the center width wise. So I moved the chair 50cm to the right. The Harman Axial Standing Wave Calculator came in handy and was easily understood. So far I've moved my listening spot forward slightly, to the right, and increased my ear height. All 3 help me avoid the standing waves. But this means all my symmetrically placed acoustic panels are off compared to the new optimized seating position. And I need a longer power cable for one of the woofer subs. We've opened up a can of worms!
  6. Thanks for the responses guys. Yeah - I've done the test without that box - no chair - on the floor - raised higher than normal - over the to the left and right - etc. That dip at 40 is always there. I also looked at the room simulator software as well - a think 40hz dip is a characteristic of this room size. Can I hear it ? Yeah - I have a few tracks that I know have some deep percussion bass that I've heard on other speakers in other rooms and setups. I've moved the mic back and forward in steps of 50cm and moving forward slightly will reduce the dip by about 5db but the top end and other parts suffer. How to tame the sound above 2khz? More absorption at the front? I am thinking a sub at the rear of the room might be needed to sort out the dip. Was hoping someone had a similar case and could comment.
  7. Hi guys I've finally reached a point where it was time to measure the room and see what really was going on with the acoustics. I've spent a few hours with REW sofware and a minidsp umik1, watched some youtube vids, and read some FAQs. Here is a picture of the basic curve I get. I ran measurements in about 12 positions around the single listening positions and all are very similar. Measurement db was calibrated to 75db for the room. Room is 5.9m L x 4.4m W x 2.5m H. Looks like we have a big dip around 40hz. Any tips on how to fix? Would I be right in saying that everything else on the graph looks ok?
  8. Sorry I am looking at the method for the non Classico version. That tilt won’t apply the same way for your trio. Let me see if I can find the correct method.
  9. I’ve just read through the trio manual and it is the same principle as the duos. For page 22 - speaker distancing - the Jim Smith method was excellent as his method takes into account room modes. I started with what the manual recommended then applied the Jim Smith Method. For page 23 - that tilt is critical for seating height to horn height. When you can get close to what it shows the effect of the timing mismatch becomes evident. Try your best to get the bottom lip of the top horn to reach the back upper end of the tweeter case. This setup is identical to the duos. i would move the tweeters back to oem position. a lot of guys don’t use the stock speaker cables to connect the drivers. I’m not sure if this is the same for the new trio.
  10. Hang in there. These horns take time to get setup right. My optimum setup for room/speaker/listening chair took about 2 weeks to get right. During this time I kept thinking I had made the wrong purchase. I also moved from panels to horns. And would say advantgarde horn setup was advanced/more complex than other box and panel speakers I’ve had. After trying many configurations the ultimate setup for my duo omegas was the original factory recommendations. Including the tilt, horn height adjustments. However it was better to run speaker cables directly to the mids instead of the tweeters. Bass crossover recommendations where better when increased slightly, but similar to factory recommendations. Time alignment to said to be off in the tweeter, but after correct setup, as the designers intended, I realised that this increases micro detail. I would recommend you stick to the factory recommendations as close as possible and fine tune from there. just my two cents and I hope it helps. But yeah - I know your pain with setting up these horns. good luck
  11. No hiss is very good. I still get some minor hiss with a pass Labs xa 30.8 on my horns. Paired with the ref6 and ls28 in both cases. How will you solve this bass problem groovy? Did the supplier make any suggestions? When I had the rel 5sho in my system I could never get the sub bass level correct. Some tracks worked well but most did not. Hard to fine tune in my experience. introducing a crossover box was going to be next but I never got that far. Auto calibration on the xd units is a big win in my opinion.
  12. That's great that it's sounding good already. Most guys complain that they can't get the balance correct between the bass section and the horn section even with the stock woofers. I love the look of the ref160. It's not a common choice for horns - how do you find them with your horns? Do you get much noise/hiss from them?
  13. Interesting! Sub231 does 60 to 350hz. didnt the supplier mention this when you didn’t buy matching subs with the trios? your future might see two more subs in your system.
