Hi again All,

Am waiting anxiously for my actives and in the meantime have been thinking about setup. I will mostly use them for music in a 2.1 setup. If I were to add surrounds for occasional tv and blue ray movies, would axiom m2s work ok or would I have to get m5hps because of the actives? Also, would I need a center speaker?

Thanks much!

For movies it is ideal to have a center channel speaker as that is where the dialog comes from. The two front speakers can create a "phantom" speaker if you don't have a center, but for true movieoholics you need a center. smile You could use M2s for left/right channels in a 5.1 setup, or 4 if your going to have 7 left/right/ and left rear/right rear. The next step is Atmos and adding ceiling speakers. wink

It is addicting...

I have found a center to be a "must" even with actives. I've tried listening from many different positions in two different rooms and the results are the same; a center is required. Get the 160.

As for surrounds, I recommend the QS10s. They are linear enough right down to 40Hz at high SPLs for surround duty.

Don't use QS10 surrounds if you're going full Atmos. The Atmos spec is built around direct firing (monopole) speakers.

If you are only interested in five surround channels, then Atmos provides no benefit and QS10s are the way to go. I think any Atmos track will just be presented in TrueHD without overhead speakers.

You might want to read my review (the first one) of the QS10 at the link below.

Agreed, QS10 is best if you're wanting to do old school 5.1.

Receivers/processors will only decode Atmos if overheads are present.

I am quite sure a blast from twin active LFR1100s connected to ten ADA-1500s can de-link the polyproteins found in the novel coronavirus and cure anyone.

Cool obliterate the virus with SPL.

I've been saying Alcoholics beware Corona is a killer. In more senses than a virus.

Yeah, it's a funny old world.

At the risk of nitpicking, IIRC the bass channel is 4 ohm and the rest are 8 ohm, so max continuous power would be 250W bass plus 4x 125W for the rest, or 750W, assuming each channel happened to draw the maximum spec'ed power from the amp (which is incredibly unlikely).

That said, your question is just as valid if you replace 1000W with 750W...

... and we'll probably use about 10W most of the time.

EDIT - I don't believe Mojo is quarantined... he's just self-isolating so he can spend more time re-arranging speakers.
