the choice of gear is also budget driven since HT has a lower priority.
but wouldn't the MF and especially the HF response of the Magnepans still point up the flaws in movie sound of a certain vintage?
The modest MC1s are a two way "quasi ribbon" design and are used as surrounds. Most vintage content is stereo at best where they don't speak. Even if one of the "surround modes" is selected to *create* rear channel content, its output is inherently lower.
In any case, do you find the sound stage of the Magnepans wide and deep enough to where there's no apparent "hole" in the middle?
Did you click my moniker and follow to the gallery where pics are found? They are set pretty far apart and their hinged mounting allows for fine tuning angle to listening area. Since they are relatively narrow, dispersion is pretty good. Most folks have no idea what they (or the Acoustats) are. :)

If that's a subwoofer in the corner and you use it with the Magnepans where does it cross with them? Are you saying that you have two pairs of those MC-1s that you use with the Oppo player? Or is the other pair some Acoustat model?
So, when you toe in the Magnepans at ~ 30 degrees there's a wide enough sound stage to void any need for a center speaker?
To realize ~ 60db SPL at 1kHz at ~ 10 ft, about how many wpc does a pair of the MC-1 require?
Can you describe the sonic character of the highs, mids and midbass?
What's the step model from the MC-1, and do you think it would be worth it for movie sound that was hit with somewhat less compression than usual, like the BD Edition of "North by Northwest" (1959)?

Strictly speaking, the subs are actively crossed by the Emotiva (also called MC-1) processor to the Acoustat 1+1 mains and subs at 80 hz. High passing the 1+1s improves headroom by relieving them of the bottom octaves. The other sub is located at right rear just into the sunroom. In this pic it is just below and left of the right surround with a small igloo atop it. I use Emotiva "virtual copper" wireless connectivity with both. Works fine for the limited bandwidth required.

Just one in rear for surround.

Again, it is the Acoustats used as mains running phantom center that provides the sound stage. Dispersion with the one panel wide model works great. Years ago, I had 3 and 4 panel across panels and they are much "beamier". Previously used a Magnepan center but when we remodeled the space, it really didn't fit in with the minimal look I wanted nor do horizontally oriented centers seem to offer the same coherency with tall mains.
To realize ~ 60db SPL at 1kHz at ~ 10 ft, about how many wpc does a pair of the MC-1 require?
Both sets of speakers are fairly insensitive at 88 db/watt/meter but the XPA-5 power amp delivers 300 watts/channel into their nominal 4 ohm load. Not sure I have an exact answer to your question.
Can you describe the sonic character of the highs, mids and midbass?
If you refer to the MC-1s, they are pretty darn neutral and match the 1+1s very well. They're only rated down to 80 hz +/- 3db. Both exhibit what I would refer to is a natural midbass timbre as referenced with acoustic instruments including string bass, tympani and concert drum. Likely wouldn't satisfy, however, a rocker used to JBL punch.
What's the step model from the MC-1, and do you think it would be worth it for movie sound that was hit with somewhat less compression than usual, like the BD Edition of "North by Northwest" (1959)?
Not entirely sure I understand your question. One step up from them would be part of the floorstanding line like the LRS+ or the .7. Some folks even use a pair of MC1s flanking the video screen as center which would better retain the vertical line source.
