Wow... those will be very nice!

I will not have the wood horn, but a JBL 2380A. I hope to have the celestion axi2050 for all 5 channels. For the center... c urgently Inam looking at a 3 box setup WHW with celestion ftr12-3070c woofers in boxes to each side of a celestion axi2050 in a jbl2380 theater horn (imported from Japan as this one is very rare...it has a round reinforced external throat to support heavy compmdrivers).

Been quite awhile since I was here...some updates...we have moved to a rental townhouse while we prepare to put our house up for sale. Once it isa sold we will be ready to move to either Europe or South Korea (in that order). Meanwhile due to space I have been working on setting up my system again as a single pair of K402MEHs. The f20 sub horns are in the garage and will be going up for sale...if they do not sell... I will strip the drivers, and keep the amps and walk away from them (I hate to do that, but the reality is unknown as to how much room my next setup will have. I also will be selling my Marantz AV8805a...if I do not sell it, then I will take it with us and use it with a transformer until I find a replacement and either trade it i with the transformer or sell it with the transformer.

Update I have 4 custom made Roadie cases being made for the trip when we do a ocean household move. I also have ordered my new Crossover... A Xilica Solaro FR!-D with 64x64 Dante and also some analog inputs and outputs for the time being. The intention is to sell the Denafrips Athena and Pontus 2, and replace them with a pair of Holo Dacs with with or without the preamp module built in and run them after the Xilica. On the source of the Xilica have a Denafrips Gaia for digital source selection.

By going this way my Ladder DACs (vertically run with a stereo DAC per channel) stay in use for HT and Stereo, Down the road I will decide what AVP I want to get with DANTE and also run Dante power amps for surround, center and possibly heights. If I return to a sub I will most like get a European model or two (all depends on the construction and size of the Home we buy and can afford.

On the AV side side... I will most likely move to a 3 laser UST projector.

Good to hear from you and best wishes for a smooth move when that time comes. I’ve greatly appreciated your posts from Mexico and some of the fabulous custom work done there and hope whichever part of the globe you next call home will afford you the same time and opportunities for more!

 

[NBPK402]

Thank you. The big reason for the move is to be closer to my wifes sister in the Netherlands, and also being at 6000' is hard on both of our health. We found this out when we traveled to South Korea earlier this year and also to the UK last month...we def need sea level and a moderate temperature (South Korea does not have a moderate temp and would def require staying inside for 2 moths a year with the AC on 24/7).

I will post some pics as new equipment and the center channel when it is completed.

Today I finally got around to a idea I had thought about to make my end table look nicer (IMO), and more stable. I changed from the tripod to 6mm althread rods that use some cone spacers to locate the reel and the CF Tubing...also i am using what is left of my spike equipment feet which had a spacer with a angle cut on one side and are threaded for 6mm. This is the same setup i used for my AV Rack before and i figured a flexi rack end table might be even more stable. It is! I am waiting on some more allthread rods which should be in on Tuesday...so I will complete the other one then.

One modification I want to do is remove the bottom reel and use some 1' thick Parota Hard wood circles about 6" larger than the reel with the 6 holes lining up for the althread and then a recessed bottom for the allthread washer and nuts.

The final step will be when I take one pair of my horns in to have them touched up... I want to have the reels painted to match.

Comments?

Wood always looks better to me, so I like the idea.
Thinking out loud … what if the table top had only the flat reel portion sandwiched between wood and glass … requires a lot of mods … height, how to fasten … probably not worth it.

Is althread a brand name for a particular brand of threaded rods? I zoomed on the photo and looked for thread on the vertical rods, but can’t see it. Maybe due to resolution?
Anyway, it looks much nicer than I would picture a threaded rod to look like.

Thank you for your comments... I had thought about wood under the top reel and my wife shot it down...she felt it would be to unstable due to the weight on top vs the bottom pieces...hence why I am going with the parota hardwood bases. Allthread is a name for threaded rod (not sure if it is a brand or just a term). The reason you cannot see the allthread is it is inside of the CF tubing, which I used as it allows a smaller diameter allthread rod, and give a more finished look to me of the end tables. What i did was basically adopt the "Flexi Rack" design and implement it into the reel end tables. Flexy Racks are a inexpensive design that virtually anyone can use as it only requires wood, allthread rods, washers, and nuts. My last rack that I converted to a TV Stand is also also a Flexi Rack. The last Flexi Rack and Flexi end tables, I experimented with smaller diameter allthread and larger diameter CF tubing...to cut down on weight and move away from the industrial look...not sure if it is for everyone, but it fits my current needs.

Carbon fiber… Good move to make it look professional & polished. Thanks!

I just received my Solaro FR1-D crossover on Thursday, and figuring it out was difficult to say the least. Last Night we finally found out they have templates, and we downloaded the 16x16 template and it populated it and showed all the cards I have installed. This crossover is a Analog to Digital and then digital to analog for now, but also with card changes is a 64x64 Dante crossover. It also will allow us to try out FIR filters which is the reason we got it.

The plan is for now to just use it as a crossover for 3 channels bi-amped via the Marantz av8805a, and then after we move...get the Storm EvoOne processor and then use Dante to the Solaro and a few analog outs for running a pair of ladder dacs for stereo and possibly Dante amps for the remaining 5 ground channels, and 4 heights. Then if the room and neighbors are not a issue...run a pair of Perliston subs. The only downside is it uses blocks for the cables...but luckily I still have a Minidsp ddrc88a that I am not using and can pull the cables from the blocks it has and move them to the Solaro.

I also have purchased 2 Synology 8 bay NASs, and a expansion unit. I have all my 4k movies on the Synology and the expansion, and then 2K movies, TV shows, and Concert Videos on the 2nd Synology which has smaller HDDs.

My Zappiti started having issues with seeing the LAN also recently and now cannot connect to any external devices. I then decided to pickup a R_Volution Mini, which now saves me from the yearly software fee, and takes up much less space too. The only issue I have is a strange one...On the R_Volution remoted when navigating the menu setup via the wheel in the center of the remote...it only will do down if I use my fingernail to hit the absolute bottom of the wheel. Anything but the absolute bottom of the wheel, does absolutely nothing. It is as if the remote internal buttons have shifted for the bottom function. All other functions so far work just like the Zappiti remote did.

Give you brainiac fingers with more FIR...

Give you brainiac fingers with more FIR...

Just got the Solaro setup for FIR for Left and Right channels only... just reduced the number of inputs and outputs from 364x64 to 32x32 by switching the frequency to 96khz. We still have 8 PEQs per input and output channel for all channels...plus FIR for stereo channels. I had to get some new XLR cables and found a set of 10 3M cables in different colors. Now I can easily tell which cable is which. When the cables arrive I need to cut them up as one end needs to be a pigtail for the connectors on the Solaro. Hopefully early next week it will replace the XP4080.

My friend, I suggest you have a look at https://github.com/VilhoValittu/DecayCore if not for the FIR filters themselves and for the diagnostics... Good luck with your new kit...

 

[NBPK402]

I had a few problems like only Pink noise worked and only for the left channel. Swapped cards, block, and cables to no avail, and rebooted several times thinking the project might have gotten corrupted. This morning I was looking it over to try and solve it and noticed the the right channel HF, and LF were not linked from gain to the mute modules...linked them and uploaded and it works perfectly! Now I am going to need to do another REW to see if the tune is good here or if it needs to be modified before running Audyssey. I am hoping to have the center channel built in the next month or two.

 

[ddude003]

It sounds like you are making progress...

Not only did I make progress, but Xilica sent me a new Project file that is selectable between 2 channel and 6 channels, for further mods when I get my Storm EvoOne next summer. I would buy the Storm now, but the duties and loss of warranty dealer help would be lost when I move. At least I will be in Northern Spain with Storm Dealers close by,

Enjoying the K402MEHs now cabinetless still but no stack through the Marantz AVP8805a until we move.

 

[ddude003]

That is great that Xilica would support you that way!!! And I can't wait to see how you use that extra FIR feature... Inquiring minds and all that...
