Finally have some progress...
1: fiber HDMI cable is on the way
2: 5 50wpc amps on the way
3: amp kit cases on the way
4: 4 small horn waveguides on the way,
5: When we get back from Europe I will have 4 DIY Klipsch Belle bass bins ready to go.
6: last few pieces for the rack shelves are at the powder painter now.

We are awaiting an estimate for my wooden trough/acoustic panel holders to be installed above the windows and on the other 3 walls.

Today I worked on finishing up the new rack...when I found one board had a huge crack in it. I glued it, and clamped it, and will install it tomorrow. I also found a much nicer way to make the boards clear the bolts holding the shelves...I used a router so it is totally hidden from the top. This looks 100% better than using a jigsaw! All that will be left after tomorrow on the rack will be a stone Cantera top to match the stone in the right side of the picture. If I can I will start on my new pie shaped amp modules before we go on vaction...If not then they will get done at the same time as the new bass bins. I hope to have enough cash to get 2 Dirac boxes too by this Xmas...as they will also be my crossovers.

Update... I just ordered 4 Klipsch rp160m speakers in cherry. These will be used as my front channels until my k402s are ready...once the fronts are ready these will be used as my surrounds, and surround back speakers.For the time being I will use my 4 channel Yamaha Pro amp for powering them until I get the B&O AMP modules installed in their case. Hopefully I will have 7 channels plus 4 Atmos channels by November. Next year will be projector, screen, and new AVP time.

Yeah it has been quite a while to get everything up to where I can actually enjoy my setup...as usual money slows down progress. Lol

We are doing fine down here during the Pandemic. I hope everyone in the USA is doing well too.

I wanted to go with a laser projector, but I was worried about our dogs and cats...so I picked up the 86" LG at Costco on Mexicos Black Friday.

How does impulse response and phase response affect a speaker? I am thinking impulse would be more dynamic and phase would affect soundstage...am I right?

That's an 86" display? WOW, that room must be big because as mentioned, it looks small in that photo.  

Good to see your progress. I love seeing build threads like these.

If they ever make an affordable and high-performing 92"+ OLED screen, I would likely give up my projector. I think I'm safe in keeping it a while longer.

I think I saw that Samsung or LG had a 110", but I bet it is big $$$. I miss my projector as IMO it is always better to have the sound behind the screen. I decided to go LED FP because we have cats and I wanted to go laser, but they would most likely look at the laser and even if they did not...they like to watch the screen and would jump on it if I was not paying attention. My K402 MEHs are almost completely tuned now. I am really liking the way they sound too...def worth the time and $$$ to build them,
