We are now living in Mexico, and will be moving into our new house in the next couple of weeks. The new house living room will be our new home theater, and stereo room.
-
Well we are now living in San Miguel de Allende Mexico in a temporary house until we either buy or build one. My projects are now starting. 😊 I now have the 14 channel amp up and running, but it will be torn back apart when the 5 or 7 k402 clone Synergy horns are built.The amps will be moved inside of each speaker along with a minidsp 2x4. The first item I have started on is our home entertainment rack for our living room. I have one rack in place so far(there will be one more rack built, and then shelves will be made that will be attached to the 2 racks sides to make a 3rd rack),but I am still waiting on some 1' long 2" x 2", and 3"x 3" aluminum angle for supporting the shelves. The shelves are 20"×20", and were made from 2" thick Mesquite wood. This should be completed by the time we get going on the Synergy speakers. A friend of mine wants my help in building a CNC machine that can do 5'×10' pieces. This will be built in about 6 months from now, and then we will make the horn mold for the speakers. We will use the CNC Machine to make the cabinets, horn driver, and woofer mounts. Hopefully this will coincide with moving into our own new home. I am debating on also making some small synergy horns for our living room too.
Not sure why my image is sideways as it is perfect on FB.
-
Open your image on your desktop. make sure it is right side up and re-save. Even if it is right side up, still re-save. Then when you post it should stay right side up.
-
Here is an updated pic of the new config, for one rack. There will be 2 racks separated by a 6' long piece of t channel to support our 65" FP.
I will be making a sandbox for the turntable, and also have a discover made that will attach to the sandbox.
-
Same thing happened on the new images. I opened them, and reserved them, and they still appear here as sideways.
-
For images that are in a file on my computer, I open the image and after making sure that it is right side up, I save the image. Then when I post, it stays right side up.

I do not know why this is happening. I went back to the original file, and opened it, rotated it, and rotated until it was correct and saved it again. I posted it, and it is still 90 degrees off.

I have decided on what speakers to DIY for our living room (7 diy synergy horns will still be the speakers for the theater). I am building some paper mache horns. Here is a link to a review on them...http://www.tnt-audio.com/casse/paper_mache_horns_e.html
I am looking at making bass bins that will have 2 15" woofers stacked one on top of each other, and the horn overhanging the top of the cabinet. I might do just a single 15" to keep the height down on the horns.
-
Update... we will not be building the paper mache horns...only the synergy horns , and subs.
Well today we put an offer on a house, and it was accepted...My wife, and I both fell in love with this house as soon as we stepped in The front gate.The house is 8 or 9 years old. The first picture is our entrance, the next 2 are the kitchen living, and dining room, with the 4th pic being the wine cellar.
The living , dining room bar is 31'from the rear wall with the doors, and windows. The room is about 19' wide with a boveda ceiling that hits 31' high. I anticipate mounting the projector under the loft right over the kitchen bar. We will be going with 5 or 7 K402 Synergy horns, and then covering the JBL surround speakers in white acoustically transparent material so they blend in with the walls. I have already ordered $600 of roxul Rockboard for my acoustic panels, and my wife said we can do artwork coveri vs on them to make the room look nice. The corner traps will be white only I think, and we will get some nice curtains for the back wall. I will work on a 200" 2.40 AT screen that will drop down. We will be disguising our speakers, and all the equipment will be in another room. I will be dismantling my 14 channel amp, and converting to a balanced setup with the amp modules, znd minidsps 2x4s on/in each speaker. I also plan on using my Insteon wall outlets to power each speaker individually. The plan is to be able to power on only 2 speakers if we want stereo, and 7 if we want surround, and all amps if we want Atmos.
I can't wait to start on this room setup. We are currently in a lease till the end of the year so we might rent the house out to vacationers u til our lease is almost done, and then start moving stuff over. I hope to have the speakers done by the end of of the year, which would also get us to the end of the lease. I will post up pics as we move along.

Nice place. You definitely are going to need some sound treatments. :) Looking forward to the room conversion.

Thanks...This will def be an Interesting room treatment, for sure. I also read something interesting the other day which will throws another wrench Into this setup. What I read was that at higher altitudes you need more power for the high frequencies. I had. Ever heard of this before, but it made sense to me too.

Fill that wine cellar!

Fill that wine cellar!
My wife is thinking about brewing beer there, and storing wine too. I think it holds 98 bottles.😊

That room looks bigger than 98 bottles, unless you just want to sing the 98 bottles of beer on the wall song !
-
I think the room was about 8 foot deep.😊
I was wrong it holds 100 bottles.😊

Well the buyers of our home just signed so we are def getting this house...we should be moving into our new home in the next couple of weeks. I have a dilema now, where do I put the screen?
When you look at the pictures the distance from the windows to the loft is 20', the room is 19` wide, and if you go from the windows to the bar it is 30`.
Option 1: I was thinking I could mount a 160" 2.4 electric AT screen from the loft, and put the 3 front speakers behind the screen. If I go that way the kitchen would be viewable from the living room when the screen was up.
Option 2: Build a support to hang the screen from about 3` from the windows, and put the speakers behind the screen.
Option 3: Hang the screen from the wall across from the screen...downside is it would have to be mounted to the wall and the screen would only go down to 3` from the floor due to the speakers.
Ideas, suggestions?
-
I have a solution...the room is 19' wide, and the screen is 15' wide. I will make some sort of rails to put on the side walls, and then connect the screen to it...then I can have the screen come down in front of the speakers. I still have to measure the left side to see how low the screen can come down withthe door on that side, as it might be right where the screen rail would need to be mounted.
-
I was not quite following the problem, so I am lost with the solution.
-
The problem was how to mount the screen... I now have a way to mount it... I had forgot how close in size the screen was to the room width. Now I just need to install rails, and make brackets to hold the screen in place, and then motorize it for lifting, and lowering.
-
Looks like I will have some changes as the wife wants to have mirrors on the wall on the loft for her to practice dancing. This means I will no longer have 10' for the audio rack, but maybe 4' max, and still only a little over 2' high. The speakers will still be next to the windows but the doors will not be used behind the speakers (a plus for me), only the glass door to the left will be used. Room darkening curtains will be used, but not black, and a couple of carpets will be used for the floor too...again not black, but grey or blue with some white stripes (best compromise I could get as we will be getting the, from Costco).
On a 19' wide room, I will have to leave about 3' per side since we will be using the door which opens inward on the left, and we have the fireplace on the right. Not as much as I had wanted. Should I skip The center channel?
The old JBL speakers which are angled at 45 degrees as I recall will be set up as height channels, and as Auro3d channels. How do I calculate the height of them?
Would it be best to run side surrounds or rear surrounds, With the heights above them?
-
Does anyone know how I determine the placement and angle of my height speakers... I want to set them up for Auro3d, and was told They could also be used for Atmos.
-
How about this -

Thanks Craig. If I understand this correctly... I need to mount the speakers at a 30 degree angle from the mlp for the 2nd layer heights(which is all I will be doing), and then angle the speakers toward the head of the person in the MLP. My JBLs are 20 degree...so I will need to get one up, and then figure out what angle to set the speaker at, and modify the mount to get there..
I was hoping to have a 5.1 on the bottom set, and a 5 on the top set, but apparently it is not recommended to have a center on the 2nd row unless you are running 7 on the bottom. I wish I could run 7 on the 2nd and 5 on the bottom, if I cannot run 5 on each layer.
I need to do some calculations... hopefully I can run the heights above the windows otherwise I would need to run them in the corners which would also be out of range (I have not measured just assuming).
I will be doing a 9.1 setup.

My surround speakers are totally " out of spec " for Auro 3D or Atmos. So, I continue to use DTS:NEO X !
-
I would set up for Atmos, since that seems to be the system that is making it here in the US. Select the system you want to build in the attached link.

is there any content for Auro3D?

Do you now if there is any free software that I could punch in the dimensions, and angle of the speakers to come up with where I need to install the speakers? I am not good at calculating angles at all.

I don't know of any myself. I use tape measures, laser pointers and my eyeballs for installing speakers in my theaters.
You room will also partially dictate where speakers are going.

Thanks, Craig. I guess I will have to try and rig up a protractor, and use my laser pointer, and wing it... I was hoping I could come up with a measurement for the height channels.
-
I rigged up a protractor, laser light, and it looks like my rear surrounds will be right in the corners of the room where the loft meets the living room. The speaker bottoms will be at about the bottom of the loft. The front heights will also be at about the top of the front glass windows.
Now the dilemma... according to the auro3d specs the front speakers should be 30 degrees from center left and right(with the heights above them). If I do that it means the main front channel speakers would have to be in the front corners angled toward the MLP...it also means that the speakers would be halfway outside of the projection screen. I was planning on putting the speakers at the inside outer edge of the screen, and firing through the screen. The 2nd problem is that if the speakers are installed angled it might cause a problem with my screen mounting as we were thinking of running the tracks for the screen raising, and lowering in the corners for stability. We also were planning on the tracks running down the center of our bass traps, plus the speakers being so close to the fireplace messes up the first reflection panels too. What do I do...put the speakers inside of the screen edges, and then put the heights above them (which allows us to have some bass traps in the front, and puts us at about 20 degrees per side angle for the speakers ), or adhere to the specs for Auro3d, and put them in the corners with the heights in the corners above them?
-
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.

For an Atmos system, use Dolby's guide.

Thanks Mike, my angles will be for a Atmos/Auro3d...on the Auro3d site they have the angles for a Atmos/Auro3d setup.
-
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.

Progress...
86" 4k tv
3 MEHs completed
3 channel Icepower amp completed
Next projects...
2 25" cube MEHs made out of plywood, and mdf
1 Icepower amp cosmetically identical to the black and silver one, but in silver and no handles. This one will be for 4 biamped surrounds with builtin minidsp 2x4hds, and 4 height channels.

stranger danger!
haha long time no see hope all is well.
man that 85" tv looks TINY in that space. pretty awesome

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.
-
great to hear your well and enjoying the good life!
-
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,
-
All 3 speakers now are tuned.
-
Updates to my system on the way...
2 MiniDSP DDRC88As (1 new)
3 Ampcamp amps (used) for. Dr8v8ng the fromt 3 hor compression drivers
I will be selling
Musical Fidelity MX VYNL phono preamp
Xilica xp4080
4 Klipsch RP160Ms...2 with stands attached
-
Update...
I have rewired the speakers so each woofer has its own 125asx2BTL amp, and also pulled all the 50asx2btl amps from the amp case. I replaced them with 125asx2btl amps...so now the amp is strictly for the front 3 channel woofers. I also built 3 new amps using the 50asx2btl amps, and each speaker has one next to jt for driving the compression drivers.
I now am working on building 3 amp switchers for me to be able to switch from the ampcamp amps to the 50asx2btl amps. In addition I am taking my other big case and making it into a Plex/ Roon Rock server with a Roon endpoint, and 10.1" touchscreen.
I hope to have these done by Christmas and also one prototype mini MEH without a cabinet. I want to make 2 without a cabinet with one having 4 15" woofers. In order to do this I need to order 4 more woofers still. The reason for wanting to go with 4 woofer and 4 amps is because of how much better my lower bass was after rewiring forcindividual amps per mono amp vs 2 speaker running off of 1 mono amp.
-
Today, a friend helped me get my HT valances done...
-
Today I spent the afternoon at my friends shop telling him what I want and then he programmed the CNC for the project. The results of today are in the pics. What I am doing is reconfiguring my 6 channel amp into a 7 channel amp. The amp will be powering the front 3 speakers woofers, and 4 height channels (each speaker will have its own 170w (or in the case of the front 3 200w per woofer) mono amp). The amp will be going back to one power cord, and will have 3 power switches on the front panel. 1 button for stereo, 1 for center, and 1 for the heights. I am trying to mix mahagony wood with aluminum for all my amps, router, and my Roon server. My speakers are all mahogany...as is my rack too. On the rear panel I decided to use a number instead of words for each input and output pair. I figured there was no need to put input of output as it is obviously XLRs for input, Speakon for outputs, and a single blue Powercon for power.
This week I am going to try and get the holes in the aluminum front plate drilled, contact cement the 1/4" wood to the aluminum original faceplate, sand, and clearcoat. Then drill mounting holes for the rear panel, and all the inputs, outputs and power, sand, clearcoat and assemble.
-
Update to my setup....new rack, horn subs, and Mesquite backed k402 MEHs. Coming soonnew amps, and speaker stands coming over the next 2 months
-
New rack is built of Parota hardwood, and is a flexi-rack. The rack has (7) m6 allthread rods covered with carbon fiber tubes, a metal frame spaced below each shelf with a 1/2" aluminum spacer and a rubber washer. The cf tubes are a.igned on the rods with aluminum bicycle handlebar covers and have a handle bar aluminum anodized spacer for decoration. The rack also has (4) 5/8" allthread rods for maximum strength. The whole rack empty is over 500lbs and has (8) stainless steel ball casters under the bottom shelf. I have another shelf and a top I can add. Once I decide on the total height...I am adding large custom (speaker grills) grills to the sides and front to prevent dust.
-
New F20 horn subs, and Mesquite woofer mounts. Speakers are now run boxless, run celestion axi2050 comp drivers in the top only horns, and 2 celestion ftr15-3070c woofers per horn.
Finally getting close to completion. Next year will also be time to upgrade the Marantz av8805a. Looking at Storm Audio, Trinnov if I can get enough money saved up before we move to the EU. If not...then I will most likely look at a Monoprice htp1... Marantz will go for sale as it is 120v, and that will not cut it in Europe without a transformer, and then it has zero resale in Europe.
-
Hopefully beginning of the year I will have a 5' wide Mesquite hardwood OB center channel completed. The center will have (temporarily, until I get another axi2050) a ev dh1 a comp driver and 2 celestion ftr12-3070c woofers. The surrounds will also be OB, and made of Mesquite hardwood...with 1 single Celestion ftr15-3070c woofer and a JBL 238OA horn and a celeasion axi2050 comp driver. Surrounds, center, and the 4 height channels will be powered by Icepower 50asx2btl, and 125asx2BTL amp modules for the time being.
