In a large room the constraints invert: placement freedom is usually available, and the question becomes whether the system can fill the space evenly for every seat without being driven to its limit.
Larger floorstanding models with more cone area, a centre with wide horizontal coverage for outer seats, surrounds planned for the seating arc, and two subwoofers in different positions to even out bass across the rows. Amplification headroom matters more here than in any other room size.
A large room needs more acoustic output for the same perceived level at the seats, and the demand rises faster than the room volume does once you account for distance. This is where published sensitivity and minimum impedance become practically important, and where a separate power amplifier for the front three channels often makes more difference than a speaker upgrade.
Two rows means two different acoustic positions. Bass is the hardest part to make consistent, which is why two subwoofers in different positions are close to essential. Surround placement must serve both rows, and a riser for the second row changes the surround heights required. We measure at each row rather than calibrating for the front seat alone.
A large room is the one place where the largest layouts are genuinely justified.
Potential fits for a large room, validated against the actual dimensions, seating rows and amplification.
In a large hard-surfaced room, reverberation blurs dialogue and effects long before the speakers run out of capability. Absorption at the first reflection points, treatment on the rear wall behind the seating and control of the ceiling reflection path are usually where the biggest improvements come from in a room of this size.

Roughly, a room where the furthest seats are beyond four metres from the screen, or a double-height or open-plan space of comparable volume.
With more than one seating row, effectively yes. Two positions even out the seat-to-seat differences far better than one larger unit.
It is often the most effective single change in a large room, especially for the front three channels driving a demanding load at film levels.
In-ceiling, in most cases. Reflected height depends on a reflection path that becomes long and diffuse in a large or high-ceilinged space.
Centre channel coverage, surround placement that serves the whole arc, and calibration measured at more than one seat.
In a large hard-surfaced room it is usually the highest-value investment, ahead of any equipment upgrade.
