That is great news! Very fortunate that shipment got out before the virus shuts everything down here. Congrats!

Cheers mate, it actually arrived 2 days early, was supposed to get here Thursday or Friday , but arrived on Tuesday, so that was a nice surprise!

10m XLR to RCA cable is getting made up for me currently, so should be able start setting this up soon hopefully

I have only the one subwoofer output to worry about for now (2 Submersives, but in a master/slave configuration).

The hole in my in-room response is roughly between 27-45 Hz, not around the crossover (set at 80 Hz) region. As I understand it, this is a function of the subwoofers interacting with my room, not phase issues between the subwoofers and the mains.

So, I'm not sure I understand how manipulating phase (independent of the method used to do so) will help. However, additional subs can help mitigate it. Which is what I'm doing.

With a single slave setup you can’t play phase games. Setting different delays on multiple subs acts like moving the sub around the room. It requires a separate amp for each sub to play that trick.

In the case of 2 subs being fed the same signal and positioned at the 1/4 and 3/4 points on the front wall (similar setup to mine) you might find that moving your seating 30cms forward or back from its current position may result in a nice flat response. That's what happened in my room, I had to move my couch 1.5ft (0.46 m) further back than I'd prefer, but it resulted in a MUCH better pre-Audyssey frequency response.
Though with the 2 rear subs incoming and Mark's assistance setting them up, you should be good to go now

Right. And it seems like the fact that I currently have a single slave setup hadn't gotten across when you made your suggestions, which seemed to be a non-starter for my situation.

To be clear, I was not second-guessing Mark. I implicitly trust his advice both from a technical perspective as well as to be one that's not self-serving (e.g. he advised against the 12C's in my room and I ended up getting the 8C's, as well as suggesting less costly amplifier options apart from the one he sells for the surround/Atmos channels to power the Embers).

I understand that and would've tried that if it were a possibility for me. I have a couple of terrible length modes that would've benefited from such an approach.

For my room and my setup, an additional pair of smaller subs represented the best choice to tackle the issues I had, with the added potential for a more uniform bass response across a larger portion of the room than was prior. As for who to purchase from, I made the choice to stay with Mark.

Will do brother! I am actually looking forward to the challenge of integrating the 3rd SubMersive in the room! I'm going to try the rear right and left first and see how it goes. Really wishing I didn't cancel my miniDSP 2x4HD order last year right about now...

I'm happy for you Jamie, truly happy for you. You've suffered far more than anyone I've ever seen trying to get their subs working properly. Now you can hopefully sit back and enjoy the bass you've been missing out on.

Thanks guys!! I'm sure it'll all be worth the wait!! Doing heaps of OT at the moment so will be looking at getting another HPi amp from Mark after everything calms down

First 3 movies on deck when the new SubM gets added into the mix will be Tron Legacy, Mad Max Fury Road and Pacific Rim... just to break the new woofers in

I have heard others HP+ subs with the same performance characteristic.

It is pretty common that when the amplifier power output increases the noise floor rises as well. I have seen this with many other applications.
After several days my effort to decrease the hum has paid off.. I even got an electrician to build a dedicated ground circuit for my AV equipment but it made no difference.
Then I followed some online instructions to eliminate the hum by removing all connections to the AV chain and check them one by one, in my case I found out the hum was caused by 3 different signal connections, and I also had to remove the ground connection from them to bring the noise level down.

Now the hum is gone and the noise floor (although not completely quiet like the older version of submersive) is so much tolerable in a very quiet room.

Glad to hear that worked.

That is why I suggested you disconnect the input. That should shown you if a ground loop or source noise was making things worse.

Yes...glad you resolved your hum issue by isolating the culprits.

As a general rule, it's usually an easy fix....in some cases a little more complicated. In my case the hum suddenly appeared and had me perplexed...panic mode...the RF signal causing grief was triggered by the missus dusting and the power cord from another source coming to close to the sub cable not immediately visible.

It's tricky to eliminate the hum when there are multiple sources.
I have to identify and disconnect them all.. the humming sound persists even one of them is still in connection, and it can be quite complicated to sort them out.

Do you any other sources connected like a firestick or media source in the chain....even though HDMI.

I do have a Roku ultra but it doesn't cause any issues. The S-video output on the prepro to the projector did cause severe hum.

Thought I'd ask....because my firestick....even with everything turned off....caused a hum thru an alternative HDMI port. It wasn't even connected to the home theater and why things of this nature at times are difficult to troubleshoot.

I wish you well....finding a solution.

Thanks and good luck to you too.

I must have spent at least 10 hours on this matter and 100+ times power on/off to locate the problem.
Since you have located the equipment/connection to the problem, I would imagine that you're close to fix it.
Sometimes replacing a faulty cable or a cheater plug may just be the cure.

You're using a "pre/pro" and a projector, and you're running S-Video?

I have to identify and disconnect them all.. the humming sound persists even one of them is still in connection, and it can be quite complicated to sort them out.
That is true. I always start by disconnecting the input on the subwoofer. If that solves it then I work my way back through the system and disconnect everything and add an item at a time.

Is it so shocking that S-Video is still being used? I have a Super Beta tape machine & a Laser Disk machine that both uses S-Video as their video outputs.

Now I use it mainly for velodyne SMS-1 OSD
It occurred to me that I should've checked the component cables for my old DVD players..

This is old school, while been a great piece of gear in it's days
And still have mine, only as Volume control for my TT. Since I rely on my Audyssey, now a day.

Recently I use it to boost ULF to simulate the BEQ effect by setting and assigning a bunch of 15Hz(lowest possible in SMS-1 ver. 2.1.3) freq gains and Q's into the SMS-1 presets.
It may not be as delicate as the Minidsp but it kinda work I can simply use the remote to switch between presets to taste.
