Ron’s New System

Loads are of impaling clips screwed to the walls, and a lot of glue.
I predict a shorter reverberent field in the mid/ high fr region
Have you tried toeing in the dipoles .. that should reduce side wall reflections a bit more and help with clarity

YesI predict a shorter reverberent field in the mid/ high fr region
Side wall reflections should be pretty well damped by the side wall absorption panels.
For some reason I seem to like panels pointing straight ahead. Toe-in affected the depth of soundstage, I think. Frequency balance seemed pretty unaffected by toe-in.
I should play more with toe-in but I don't plan on doing it for a while.
Running Balanced cables in a SE system , yea i will stand by my statement on that ..!
I don't know what you mean by a "single-ended system."
Both Gryphon and VTL are true-balanced. But Jadis is single-ended. So it is a "mixed" system.
I just realized I should try moving the acoustic absorption panels behind the woofer towers to the center of the front wall -- and see if I hear a difference.
I don't know why they're behind the woofer towers in the first place. I will try taking them away the next time Don comes over and see if we have a difference.

I've watched with interest this progression--kudos on the results there!
--having used ASC Tube traps since 1990--in my observation having had many room setups similar to yours with large full range speakers I'd be inclined to put a centre imaging stack (2) of Mid Range traps with the Diffusors pointing towards the listener.Leaving your present panels in situ.
Good listening and enjoying your journey.

Thank you for the kind words!
Does this experience include TubeTraps diffuser side out in the middle of the front wall between planar dipoles?
i'm asking because I don't know about diffusing the back wave of a planar dipoles. I'm concerned that that could confuse the imaging arising from an otherwise clean, adulterated back wave.
Ron , do you have absorber panels on side walls in front of speakers?
You would think you would get a boost in higher fr listening on axis .. unless the ribbons beam less than most ... I have always felt extent of toe in represented a preference in the roll off at the top end like linkwitz used .. assuming a flat on axis presentation
yes
I think so too. But if the panels are parallel to the front wall then at the centered listening chair I am not listening on axis.
With toe-in the drivers might be pointed directly at you.
Thanks Ron
If you have an idle moment you should just prop those panels at an angle .. making sure it's not a reflection to ear from either speaker .
Not a final solution .. just a test on further limiting panel reflections not in the absorbtion range
Wow - What a work out! The audiophelic business is sometimes harder than going to the gym?. I hope you get the improvement you wish for. Seem like great guys helping you out. Great clip to get a feel of your room. I bet all you gyus had a great swedish fika afterwards - right..??!! Haha very important when doing big hifi changes!
Cheers / Jk

Thank you for the suggestion, and for the drawing.
What would you be trying to achieve with the angled panels?
The panels are currently absorbing sound at certain ratios over a moderate frequency range then reflecting the remainder so those reflected fr will be causing smear with the direct sound .. this will direct at least any higher fr away from your listening spot ... and hopefully more clarity and more solid sound stage .. if you partially overlay them .. tuck one in say half distance or so behind the other it should be more effective lower down ... anyway that's the theory
Who recommended Absorption at side wall first reflection ? I would invariably go for Diffusion or a combi Diffusion / Absorption panel at that point Viz https://gikacoustics.co.uk/product-category/diffusion-products/
