Miller, your approach makes a lot of sense.
Indeed it does. Thanks. That's why I've been doing it for like 30 years, and why its the approach espoused here from day one.
Now I have a question. Was just thinking about this. I’ll be using a Bryston 14bsst2 amp for my Ulfers, and two separate 7 channel 300 watt per channel, all channels driven amps for the rest of speakers. I am wondering if I should add another Bryston for the moabs, since those are 600 watt @8 ohms amps, to balance the fronts and rears, and both sets of speakers are able to handle the higher wattage. Also since the tektons are rated at 4 ohms while the rest of the surrounds and atmos speakers are rated at 8. Supposedly the amps can handle the mix, but was wondering if it would be worthwhile to go ahead and separate them.
The short answer: no, because surrounds never get to much more than a fraction the volume of the fronts. The long answer:
I was just listening to Peter Gabriel In Your Eyes at a volume level on the amp barely 12 o'clock, a "normal loud" level for demos and stuff with the Khorus, several clicks below full loud rock out level. Sorry but I am not gonna drag out the meter, just trust me when I say its good and loud. So just now I'm way below that on the amp but way above that on the sound level in the room.
The Moabs are so clear and effortless even at this high level there's just no sense of strain or glare and its not even the least big fatiguing. It is however LOUD! Percussive peaks are so viscerally powerful it has my brain going, "Uh, wait a minute- I know we like this but, uh, what about our ears?" And the ears are like, "Yeah no big but if he keeps it up we're gonna be ringing him up a long term reminder, if you get my drift." And so we the millerbrainear collective agree to finish the song and then turn it down.
That's just two Moabs. You add in two Ulfs and a Center. I do not think power will be a problem for you.
