Making the tubes from flat panels must add a lot of work to the process.

Yup!
Can't figure out how to get more than 1 pic with my phone...

Nice set up Watts.Did you place traps in the corners of the back wall as well?Is the diffuser on the front wall DIY?
I have a couple of flat panels on the back walls; and a carpet. I should have more tube traps; like I said I need to make some more. The round insulation is what I will try next time. I want to make some triangular corner traps also. This room is 10.5 x 19.5 x 7, and with 3.6's and Mcintosh amps there is no lack of bass!
DIY RPG diffuser, actually 2 of them on top of each other, not sure what colour to paint it, so it remains primer red until I do. It is not random, each piece of wood is placed in a specific orientation according to a mathematical formula as researched by the BBC papers. This is not the source I remember seeing, but it looks the same:

Here is a closer picture of it
I might as well include a shot of the back of the speaker while I have the camera going.
I used Manville pipe insulation 20' which worked well.Nice job on the diffusors.In Jim Smith's 'Get Better Sound' book,he advises not placing the electronics between the speakers,but rather someplace on one of the side walls about 1/2 the distance between the speakers & the listening position.That isn't always possible,but you may want to consider it.
I have read something like that, but I think you don't want a huge piece of furniture taking up the space between the speakers, rather than the electronics themselves. Besides, at every hi-fi show this is exactly what they do; and they are attempting their best to impress others with the kit:

I found that you can use a rack or anything else as a block to early reflections from the center front wall and center placed rack You place your rack or pile of junk ahead of the speakers.
I have a pile of CDs on top of a cart with equipment materials and audio rags and the vandy 2C - reaches higher than the listening seat and blocks some mid/tweeter output and early reflections. Improves imaging and detail vs. moving the cart and box speakers out of the way.
I am considering moving the racks to the middle ahead of the speakers.
I'm not sure what difference not having the rack between the speakers really makes,but I can tell you that adding bass traps took my system to a new level.The bass is more distinct with much less boom & hang.I think that the mid range is more articulate as well.
Agree on the bass traps and diffusion. Unfortunately for me the corners are occupied by other items that can't be moved (small closet and the dedicated AC).
As to the normal rack placement behind the speakers - it creates early backwave reflections from the face plates of the equipment that are really difficult to get rid of. People do this in order to cut down on the length of speaker or line level interconnect. I usually suggest people use a fake ficus or equivalent to diffuse the backwave before it hits the racks. For some people it is possible to get the dipole null aimed at the racks. Others have used their TV slightly ahead of the speakers to block the center reflections. The adjustment should result in pulling the center image forwards to where it aligns with the rest of the soundstage.
