2 of my UM-15's are already showing signs of failure. Undoubtedly from my heavy handedness, I guess it doesn't help that I'm sending 5x their rated power to them. Or at least that much is available to them if they choose to accept it. hehe!

I couldn't even hear a difference a between my 24 being on or off, and the cone does move...

It's really the combination of ALL the cones that makes a difference. You won't hear much difference between 28 vs 29 etc... The only exception would be the HzHorn with the system playing a 16hz sinewave because the Horn is about 18db louder than all the other sealed boxes between 12-30hz. LOL!

Those failing um15s...perhaps try out the new Dayton reference high excursion model that were shown at CES. Or HST 15s that can take the pounding better.

Well the flood restoration crew are busy rebuilding my house. The basement got hit the hardest.

There was asbestos so they had to go all hazmat on everything.

There is a 40ft metal box parked in my driveway, all the cabinets, tables, seating and whatever trapped deep inside.
3 months in and it STILL looks like a war zone.

Brand new 2019 insulation, drywall, paint, flooring though...



This ate up ALL of my 2019 HT budget, so no more HT upgrades until like spring 2020 now. YAY!
and now it's almost time to leave to get back to work, for another solid 7 months regardless. double YAY!

No HzHorn V2, no 4K projector, no AC, no seating, no 32 subs, no Atmos, no doors, no trim, no remote relay triggers, no nothing!

Man, so sorry to hear that. Life throws curve balls at you.

Hope you can at least get everything cleaned up and back to normal living real soon.

Flood or fire always sucks.

Do you have insurance at least? I didn't have to do anything, they did it all. Pumped out the water, heaters and blowers, tested for moisture and asbestos, zoned everything off, and ripped out everything that got wet, moved everything that was keepable to the metal box, took garbage to dump, installed new (still on-going), light fixtures, plumbing and everything.

Why would you do it yourself... unless you enjoy doing work after work?
Maybe the HT room you'd want to do yourself, but the normal rooms let them do it all!!! Who wants to arch their back for hours taping and muding and painting and slinging drywall when they will do it for "free", and their work is 100% certified... If something bad happens in the future, then THEY messed it up, and YOU can't be blamed for it. Do nothing!

I feel ya boys.... I flooded 8 years ago on the day I paid for our 40k basement reno.... we hadnt even had 5 hours in the basement.... we, at the time couldnt get flood insurance, had to re-do everything ourselves... our only saving grace is, we had 20 people over for a party when the rains started (8 inches in a hour, then power went out, sump pump quit and it was 2 feet of water within 20 mins) but we got all my equipment out thank god.

Blasting brown notes for 10 years and counting!

What?! How many subs were affected? How does insurance handle the reimbursement cost of DIY subs? If your subs were affected are you planning on reducing the amount of different style builds, or are you going to sell all non-24's and beef up to 32s? 😈😈😈

I spent all morning reading this thread:
1.) What happened with regard to the flood???
2.) I know you said no upgrades until 2020 but opportunity knocks? (making lemonade)
3.) Can you give some more details on your Motu implementation? I checked their website and didn't see anything that looked like what is in your picture.

Hope you get every thing sorted!!

1.) 2.)
I had to make an executive decision and chuck out all the testable UPS's, about 150lbs worth of lead, so that thread is officially dead now.

I had some additional large unplanned unrelated bills pop up this week, and so now it is pushing the upgrades out to 2021 now.

The main level is all hardwood. They are currently replacing the entire floor, or at least replacing the damaged sections and re-staining the whole thing to match. To make matters worse, the floor has asbestos in it as well, so they have to zone it off in sections with plastic sheets and tape and wear special suits during the removal. Glad I ain't doing it! The original owner didn't disclose that there was any asbestos, had I known that I probably wouldn't have bought the place.

I still need air conditioning, a 4K laser projector and proper HT seating.

I'd like to re-do all the electrical in the HT, put in a second sub-panel which will be the solar-equipped one. Since I've already spent like $500 in solar already, that upgrade is happening! (240V split-phase and [email protected] with 1kW RMS charging, for starters.) The new sub-panel will power all the lights, projector, and all the low-power rack equipment and charge an electric lawn mower. That should stop the lights from dimming on every bass note!

Then I just need to buy a Tesla and I'll be gasoline-free.

Some trim work and a few decorative panels etc and then HT v1.0 will be "complete".

Long-Term I'd like to sell my house and move to an underground bunker with twice the size of home-theater (v2.0), but I'm not sure how realistic that idea is.


3.)
The Motu system is pretty straight-forward, nothing too unusual.

1 of these: https://www.sweetwater.com/store/det...rface-with-avb

1 of these: https://www.sweetwater.com/store/det...-ios-interface

1 to 3 of these: https://www.sweetwater.com/store/det...-ios-interface

1 of these: https://www.sweetwater.com/store/det...ridging-switch
(If you want a bigger system, more of these.)

and then you need a dedicated computer with TB or USB3.
It must be a dedicated PC, you can't do anything else on the box (bad things will likely happen if you do.)

For the DSP software I chose Adobe Audition, and Sandboxie Full (because Audition 2019 isn't multi-threaded).
I then manually assign each process to a dedicated core so that they don't step on each others feet.

All instances have all inputs and outputs available to them at all times as the Motu drivers are multi-tenant ASIO.

I found that 96khz to be the most stable, but you could drop it down to 48khz if you want/need to save some horsepower and AVB bandwidth.

I run an air-gapped and highly-modified version of Windows 10 Home, that has the best support for the gaming motherboard I bought and the Motu drivers. If you run Windows, NEVER connect it to the internet after activation, the automatic updates will give you nothing but problems.

If you are doing more than 32 channels then ideally the cpu would be a zillion core AMD Ryzen.
1-8 channels of DSP per core is ideal. If Audition were multi-threaded it wouldn't be such a pig.
I use an i7 8700 which is 6 cores, it gets pretty busy at 32-48 channels 96khz DSP. The MB I bought supports up to an i9 9900K if I need to throw 30% more horsepower at it. (~$400 upgrade.)

I have 16gb of ram in it, which is plenty. It's about 200-500mb per exe.
I put a 128GB 2500MB/s NVM M.2 drive in it, because it costs like peanuts. The computer boots in like 5 seconds.
If you turn off Audition auto-save feature, disk IO is zero. (I leave it on.)

The longest time I've ran the system is about 2 weeks 24/7/365 without a reboot. 100% stable, not even 1 dropped packet on any channel. YMMV.

Once you get it working, NEVER upgrade the OS or HW or FW or drivers.
If it works, don't fix it...

I highly recommend using optical HDMI and USB to eliminate all ground loops. You can get some pretty nasty groundloops going from XLR to USB to HDMI to CAT5 in giant metallic circles between the HT-PC, DSP-PC, LAN, SP, and the Motu rig.

In my case all 4 were connect to the same LAN, and the HT-PC and DSP-PC to the Motu via two USB cables, and HDMI from the SP to the HTPC, and XLR from the Motu to the SP.
The HDMI cable from the HT-PC to the SP was the main culprit, that one cable fixed the loop I had, but I ended up upgrading all of them to optical (because: why not.) Optical helps prevent noise and surge propagation and EMP as well. win-win
That alone was like $500 worth of cables though, so not for everyone.
But chances are if you are reading this to buy an expensive Motu-rig, a few hundred this way or that won't make much difference to do it properly. Just the 72-channels worth of Neutrik XLR Snakes was like $450 (and that's considered cheap.)

I literally have a half mile of unshielded copper in my room. If a sun flare or EMP occurs, my system is 9000% TOAST.


The foot-bone is connected to the chin-bone.


Even though I have a two SurgeX's and a UPS on the incoming power-line... it WON'T fix the-above problem.
I hate feeling helpless.

To solve this I need to do two things:
1) Surgically remove the AT fabric on all of my columns, and run all the wires through metal conduit (should have done that from the start anyways and I need to run more speaker wire regardless...)
2) Gut the drywall from my rack room, buy a dozen rolls of aluminium foil and shield all the surfaces to ground, and then buy a few tubes of green glue and some new drywall and put it back together. Maybe even add a quick layer of EMP-paint on the drywall just for extra-good measure.

Probably cost <$1000 to do all that. Given how expensive the equipment in this room is (like 6 figures), I'm not messing around. I think it is 100% do-able and worth-it. At this point I can't afford NOT to, even *if* it is improbable to ever occur. So consider it DONE!

Look: you'll all be turning into lake zombies etc, and i will STILL be listening to tunes and cooking food on multi-kW solar until the very end. (I'll even be able to say "I told ya so!") hehe!

How did you convince JLD to send you a sample unit of the 24? They turned me down even thou I own a company and build speakers (although these two are not entirely related).
You said you ended up paying like 800$ for it? For that money I could get two of B&C's 21DS115, so the JLD itself wouldn't make so much sense, it's just that the magnet is so ridiculous that you gotta own one I'd love to add a sealed 24 to my cinema setup, would make a great addition to the SKHorn.

BTH,
Thanks for the response and information! It'll take some time for me to read, digest, read, digest, and read again but I'll reach out to you with questions. It looks like you're using the Motu to do all of your speaker and in room corrections.

With regard to your solar plans, are you installing a power bank to store the power?

Yep.
Dude solar is not cheap!!! Version 1.0 will be about ~$7000 all said and done. (and that is 100% AIY no-kit installation to save on money too!)

Trying to make it a well-balanced design: roughly ~32% on panels, ~32% on inverter, ~32% on batteries, 4% on accessories.

Has future-potential to scale it 4x with more panels and chargers (the rest stays unchanged).
That would probably max-out all the roof space (and non-optimal sun angles / shading).

I'm not doing this to save money though... just to gain: grid-independence, fault-tolerance, cleaner power, and to be "greener".

Every deluxe-theater should have one. Just for maximum e-Peen

I also don't want to be on the "thrown back into the stone-age" list from some stupid flare/emp.
Maybe it will get cooked too or maybe it will survive, and maybe it never happens! But doing nothing isn't much of an option. Coulda Shoulda, and now ur cleaning clothes by-hand and sitting in total darkness like a caveman, standing in da walmart soup-line/cages neck-deep in nasty flood-water like a used-noob-zombie
