Head-to-head
Marantz CINEMA 40 vs Onkyo TX-RZ70: Marantz adds four sub settings, Onkyo powers 7.1.4 alone
The short answer
Choose RZ70 for one-box 7.1.4 and included full-bandwidth Dirac. RZ70 powers 7.1.4 without a separate stereo amp. Choose CINEMA 40 when three or four powered subs need individual receiver settings or seven rear high-refresh inputs matter. Its nine amps need an external stereo amp for 7.1.4. Onkyo has two independent sub outputs and a lower-bandwidth front input.
Before you choose
The reasoning and the trade-offs
The cheaper receiver offer may not be the cheaper complete 7.1.4 system
CINEMA 40 needs two externally powered channels for seven ear-level speakers and four heights. RZ70 supplies all eleven internally. If no suitable amp is owned, compare Marantz plus an amp, cables and appropriate installation space with the Onkyo receiver. If the amp is already in place, that difference can shrink substantially. Published channel counts alone do not tell you what remains to buy, and this page does not assume a current price winner.
What this is based on
Eleven required main channels minus nine Marantz internal amps equals two external channels. Ownership and actual offers determine the cost consequence.
Main trade-off
Onkyo TX-RZ70
Two independent sub outputs do not provide four individual receiver settings. The front HDMI port is slower.

About this comparison
Marantz CINEMA 40 vs Onkyo RZ70 for 7.1.4, multiple powered subs and a busy family media room. Compare complete-system costs and front HDMI limits.
Both process eleven main speakers and suit a substantial home theater. A four-sub installation and a one-box eleven-speaker installation put the emphasis on different hardware.

What matters in practice
The differences that matter
The cheaper receiver offer may not be the cheaper complete 7.1.4 system
CINEMA 40 needs two externally powered channels for seven ear-level speakers and four heights. RZ70 supplies all eleven internally. If no suitable amp is owned, compare Marantz plus an amp, cables and appropriate installation space with the Onkyo receiver. If the amp is already in place, that difference can shrink substantially. Published channel counts alone do not tell you what remains to buy, and this page does not assume a current price winner.
How we reached this conclusion
Eleven required main channels minus nine Marantz internal amps equals two external channels. Ownership and actual offers determine the cost consequence.
Adding a third sub changes the control problem
With one or two powered subs, both provide individual outputs. A planned third or fourth sub gives CINEMA 40 a distinct receiver-side advantage because all four can have separate settings. RZ70 two independent outputs would need another verified distribution or processing arrangement for that plan. A splitter can duplicate a feed but cannot create a third independent receiver adjustment. The distinction is control, not a promise of better bass at every seat.
How we reached this conclusion
Intended sub count crossed with independently adjustable output count. No acoustic result or need for extra subs is inferred.
The guest laptop and seventh gaming device want different sockets
CINEMA 40 keeps seven high-refresh sources at the rear. RZ70 places its seventh socket at the front for convenient temporary access, but that input is 9 Gbps and limits 4K60 to 8-bit YCbCr 4:2:0. A guest laptop sending 4K60 RGB needs a different supported setting or rear route. If the family has six permanent sources and occasional compatible visitors, front access can be the useful feature. A seventh high-refresh source favors Marantz instead.
How we reached this conclusion
Location and bandwidth of the seventh input crossed with permanent and visiting device roles.

Marantz CINEMA 40
Supports your setup
Supports 5.1.2 using the receiver's own amplifiers. Connects 3 HDMI devices, including 1 at 4K/120Hz.
Onkyo TX-RZ70
Supports your setup
Supports 5.1.2 using the receiver's own amplifiers. Connects 3 HDMI devices, including 1 at 4K/120Hz. Use the six rear inputs for 4K/120Hz. The front input has lower limits.
A powered subwoofer is separate from the speaker-channel count. This checks one main room. Zone 2, bi-amping and unusual speaker assignments need another manual check. Allow ventilation space and confirm HDMI settings, cables and speaker impedance before installing.

Meaningful differences
What changes the fit
| What changes | Marantz CINEMA 40 | Onkyo TX-RZ70 | Why it matters |
|---|---|---|---|
| 7.1.4 from internal amps | No, add a stereo amp | Yes | Onkyo avoids another main-room amplifier for this layout. |
| Independent sub outputs | Four | Two | Three- or four-sub plans favor Marantz receiver-side control. |
| Seventh HDMI source | Rear high-refresh input | Front 9 Gbps AUX | Marantz favors permanent fast sources, Onkyo accessible supported visitors. |
| Room correction supplied | Audyssey XT32, optional paid Dirac | Dirac Live Full Bandwidth | Compare the actual desired workflow and license bundle. |
What you give up
Every choice has a cost
If you choose Marantz CINEMA 40
- Audyssey XT32 is included, so a Dirac license is needed only if that workflow is specifically wanted.
If you choose Onkyo TX-RZ70
- Powered Zone 2 removes surround backs from 7.1.4. Plan a supported external zone route if all main speakers must remain active.
Recommendation switch
The decision flips if...
Four independent sub settings are part of the installation
Choose Marantz CINEMA 40. Marantz directly provides them.
One-box 7.1.4 with included Dirac is the priority
Choose Onkyo TX-RZ70. Onkyo includes eleven amps and the specified Dirac license.
What matters in practice
Before you choose
You want a complete theater with fewer boxes, but separately adjusting several subs may matter more than hiding two extra amplifiers inside the receiver.
What this comparison cannot tell you
- No measured sound or room-correction superiority. Bass Control and other advanced licenses are separate from included room correction.
