Room dimension are 14x19. The speakers are 6 10 " apart setup in an equalateral triangle.
I have the speakers 3.5 feet from the front and back walls (back wall distance varies depending on where I place my listening chair)
The imaging is solid now I'm currently working on improving overall depth and soundstaging
The room acoustics in this room are quite complicated The room is a difficult layout with lot's of restrictions. GIK Acoustics room treatments have helped to even out the room nodes
but there is still quite a bit of tinkering left
Ideas/suggestions how to further improve the existing layout and performance is welcome !
Very nicely done! And it's interesting to read how the system has evolved over the past few years. I see that much of the discussion has focused on acoustical matters. Perhaps at this point the way to address the remaining issue that has been mentioned, involving the highs and "air," would be via tube-rolling, cartridge loading, etc., rather than placement and acoustics. Just a thought, which perhaps you've already considered.
Hi Kevin Coming over and with your measurement tool I want to test the following if it's ok with you .i'm trying to get the decay of energy more similar from the right to the left speaker. by looking at decay time graphs ETC graphs and being able to drill into one-octave bands of the ETC I can see if the current treatment has addressed most of the issues and work on improving the room further
Let me know when is a good time to give you a shout so we can set this up
Yes I moved them away from the front wall until the bass became thin and the highs and mids were too prominent. Then I moved them towards the wall until the bass became too big and lacking detail. I started moving away from wall until the bass notes became big, powerful and well defined. When I thought I was close I started to move the speakers away from the side walls then back towards the barrier/wall until the sound was being reinforced to my liking. Then I played with toe in, including having the tweeters cross in front of me. I found what I liked after some tweaking in very small increments. You're sitting where the couch and chair were and there is an enclosed stairway rising from the floor behind your right into the ceiling to the left, am I remembering correctly?
I think I'm saying the same thing Kevinzoe is sonically. I have rear firing ports also so I started with position related to the front wall and approximated side wall distance and toe in from past experience to start. I used "Solar Energy" to find the bass I liked stand up bass is great for this.
Kevinzoe nice articulation of the situation!! If you mostly listen to TT use it and not the CD player to tune, there is a difference, I was using CD's and had problems when my listening became 98% vinyl so now I don't bother or want to use CD!
I would love for you to swing by My chair is further back then the previous seating arrangement and I have addressed the side reflections The ceiling has also been addresed by placing absorbers at the first reflection points
I may be hearing things but I have some echo on certain tracks this could be slap echo The LF are better in this arrangement just missing a bit of air in the instruments
Pat, Is the current distance (i)between speakers and (ii)between speaker and listing spot the same as your prior setup? The prior setup was a very near field listening arrangement as I recall; with side walls so far apart, a carpeted floor but bare ceiling, you would have heard a lot of direct sound and less indirect sound, so you'd be hearing more of the tweeter.
Now if you are listening further away and you are absorbing side wall 1st reflections (which is somewhat of a proxy for the distant side walls of your prior arrangement) then the tweeter may sound softer. The other reason that the tweeter may sound less loud is that the bass and/or mids are louder relative to the highs and that the highs are just the same as before. The bass could very well be louder given the new location and the shape of the front wall 'trapping' and storing bass energy. Are you using bass traps in the front wall corners? If so, then experiment with different air space depths to alter which bass frequencies are impacted the most.
So net net, try to attenuate the bass (e.g. traps, move speaker farther away from front wall) or accentuate the highs by leaving a bare side wall at 1st reflection points.
Sounds like I might have to swing by again but this time with my handy dandy Dayton Audio OmniMic measurement tool. I could bring along some RPG Skylines and/or GIK D1 dffusers to try on the ceiling and/or side walls for fun.
You might be defeating what you have gained with the wood!! I would first try more inward cant of the speakers in small increments all the way to crossing the tweeters firing line in front of you. Now return the speaker to their original position. Start moving away from the side wall in 1/2" steps, can fine tune with small steps later, keep moving to hear what's being reinforced by side wall. Again put the speakers back to original position and start moving away from back wall until bass is lacking then start moving towards front wall until bass becomes mushy then start moving away until you get a well defined strong bass. All these adjustments should give you a good feel for what combinations will give the highs you like with full mids and a strong well defined bass. Oh I for got the bass port!!! LOL
Congrats on getting your stereo rotated 90 degrees and firing down the room length Pat. So, how does it sound now? Where you had no side walls before because they were so far away, are you finding now that you're hearing more of a blend of direct and indirect sound (which ain't necessarily a bad thing)? Looking forward to hearing your impressions . . .
The dodds are based on feedback of a friend who I trust his ears and has similar musical preferences I also knew there was a good synergy between amp and speaker combination
The Lenco is truly a diamond in the rough those idlers do a lot of things right IMO
