I have two masters and one slave that shipped to me on the 19th. So they should be here any day!

I am considering putting two in front of my room on either side of TV. A master and slave. But I only have one regular wall outlet there. Currently I have all the following plugged to it:
Outlaw 200 wpc x 7 amp
MiniDsp 2x4
MiniDsp DDRC-88a
PS4
Cable Box
Cable Modem
70" 4k TV
Denon x4100w AVR
... PLUS master/slave subs?

Is that going to be too much for one outlet?

Should a master/slave have one outlet to itself?

I guess I could look into having electrician install one. But that will be a pain in the arse.

Another quick question: I will potentially have one sub about 6 feet in front of MLP. One 10 feet to left. And one one foot behind MLP/nearfield. Ideally I know I'd just add delay to nearfield one... But I can't only add delay to nearfield one as it will/has to be hooked up to slave 10 feet to left of MLP. I can't have the two farthest subs in opposite corners of rooms as master/slave because I can't run speakon connector across the room from front to back.

Since all three subs are within 10 feet of MLP.. do you think it would be fine not worrying about seperate delays? Just having all three calibrated as one sub with rest of system?

I think for safety sake you need another couple of circuits. I am surprised that you have not tripped a breaker or popped a fuse already. That would be a fire hazard because the circuit now is way to over loaded. Don't be cheap you spent good money for your new arrivals don't ruin it by not feeding them the juice that they require [smile]

Ok that's what I was afraid of. Thanks!

What do you think about the delays. If I have three subs...
One foot away
Ten Foot away
Seven foot away
Are those all close enough that I can have them all as one channel in time with rest of speakers - and won't sound terrible?

You have no control over the Master/Slave - they must be the same distance (and trim I assume).  But the other sub you do.  If your SSP does not have dual outputs that operate under Audyssey X32, the purchase one of the miniDSP products.  

If you don't have measuring software (REW or OmniMic) you need to get one or the other.  That is the only way you will be able to optimize your sub placement and settings.

I have minidsp 2x4. I understand master slave operate as one.

Because I can't run front and back as master slave (can't have speakon cord going across living room floor from front to back), my only option is:

Master one foot behind MLP
Slave 10 feet to left of MLP

Master 5 feet in front of MLP

So I need to either have them all on same delay with entire system. Or I could have sub five feet in front of MLP calibrated with entire system and add delay to the one that is one foot behind MLP - but that will also add delay to farthest 10 feet away sub. I'm thinking that may be more screwy than just keeping all three on one channel and calibrated as one sub with rest of speakers.

See my dilemma?

I understand your dilemma.  But you won't know the best approach without measuring software.  Then you can experiment with the various options to see what makes the most sense.

I am of the opinion that anyone who is willing to spend the kind of money you have just for subs should make the time investment to acquire and learn how to use measuring software. Flying blind, which is what happens without measurements, will get you nowhere.

You do what you think best.  Should you decide to measure and post those measurements, I will be more than happy (as I'm sure others would as well) to provide any assistance you desire.

Have fun!!

Thanks for the offer to help! I'll be taking measurements for sure, I use XTZ Room Analyzer which is like REW. I will have everything calibrated with with Dirac Live also.

I was just curious if anyone had thought on whether the sub placements I mentioned will sound ok calibrated as one unit. I already paid over 5k for the subs nearly two months ago and still not sure if they shipped yet.. If they haven't shipped I could maybe pay more to make third sub also a master instead of slave. Then I could have them all delayed properly. But the idea was to have just two masters and eventually upgrade to two stacks of four subs- which I only need two masters for.

Oh well I guess I'll prob just keep waiting and one day hopefully I'll actually get them and be able to take measurements.

Two months and no subs? Is it some kind of special order???

He's been keeping me updated, it's a newer product. Just making sure they are perfect. They will be worth the wait! [smile]

It was supposed to be 3-5 weeks, but we found some refinements and improvements to implement in function and making them work in more rooms which the 2 customers waiting on these wanted to wait for.  Announcements will come this week on the production version of the F18+ & F18 (slave) seen in this installation.  There are also 5 customers waiting on their SubMersive F2+ or HP+ or amplifier upgrade due to a closely related upgrade to the amplifier which I am doing final testing on right now and through the weekend.  Full details will be posted this week.  With all the design and optimization which went into the HP & HP+ amplifier optimization, it took quite a bit of testing and adjusting to insure the new upgrades are equal or better in behavior and performance.

Sometimes it's easy to forget how well a past design was executed and optimized until you try to improve upon it!
