This bundle centers on strong RC-70 floor speakers paired with an Onkyo RZ70 that brings Dirac Live and plenty of channel support for a serious home theater. The speakers are described as a clear step up from RC-10s and capable of impressive sound, especially when crossed over to a sub and set to small. The RZ70 is also viewed as the safer receiver choice for demanding setups and higher listening levels. The main caveat is value, since the package looks overpriced if you do not need 11 channels, and the RC-70 upgrade matters less for moderate music or movie listening.
Home theater builders using a subwoofer, because setting the speakers to small with an 80 Hz crossover cleans up mids and reduces distortion at higher levels.
Room-correction tinkerers who want to tune bass integration, because proper crossover setup and Dirac-style calibration can make the system sound cleaner and more effortless.
Movie watchers who want a strong center-focused upgrade, because the center channel carries most dialogue and the towers add little audible change in films.
Two-channel music listeners who already have capable towers and listen at moderate levels, because the RC70s may not sound much better than the RC10s with a good sub.
Listeners chasing effortless reference-level output in a large open room, because the towers can roll off low and may need a very large sub to keep bass punchy.
Set the RC-70s to small and use a 60-80 Hz crossover for home theater. That offloads deep bass to the sub, reduces distortion and power demand, and usually improves clarity and headroom.
If you do not need 11 channels, the bundle is poor value because most of the price is tied up in the AVR. The speakers-only package at $799 is the better buy, and a TX-RZ30 has been available around $700 with most of the same features.
For movies and moderate-volume music, the RC-70s are not a dramatic audible upgrade over RC-10s when a good sub like an SVS PB12 is already in the system. The center channel carries most movie dialogue, so that upgrade is usually more audible than swapping the front towers.
They can work in direct 2.0 listening for music if you do not play very loud and the speakers reach low enough for your taste. The RC-70s still roll off in the low bass, so adding a sub and crossing over around 70-80 Hz is the cleaner long-term setup.
Yes, the TX-NR747 should easily drive these speakers for normal use. If you already have a decent subwoofer and do not need new AVR features, the older receiver is enough.
I am incredibly underwhelmed by the RZ30 compared to my Pioneer LX505 and the RZ70 is a step up from the Pioneer.
Just curious: what is it about the RZ30 that underwhelms you? Are you using it mostly for movies/TV, or for critical 2 channel music listening? Are the speakers crossed over to a sub?

Interesting, for us we compared it to the RZ70 on a 9 channel SVS Prime/Ultra setup.
At average levels, difference was not significant, definitely not over twice the price difference.
Adding Bass Control made a much bigger difference for us.

I run a 3.1 on my TV and switch to 2.1 for music. I have Martin Logan and a 14" Klipsch. When you turn it up to ear splitting levels it just is lacking compared to the Pioneer 505
So I missed out on just the speakers alone for 799. Is this worth getting or just wait for the speakers to come back at 799? I have a receiver (tx-nr747) but it's 10 years old. But I doubt I'll ever need the 11 channels of this one. I had built in ceiling speakers before but just moved so now getting floor speakers is all new to me. I do have a sub already.

Yeah I'd wait. This bundle isn't worth it if you don't need 11 channels, you're grossly overpaying for the AVR.

I suggest you just wait, it likely will come back.
Your 747 will easily drive these speakers.
So unless you need some new features, you'll just need to add a subwoofer.
If you wanted the features of this receiver, the RZ30 has pretty much all of them and it's been $700.
Well someone mentioned, maybe if you listen at ear splitting levels the RZ30 might struggle.
Have this paired with a RZ30. Absolutely blows my local theater away. Get a UMIK-1 when you do the DIRAC with a laptop and enjoy audiophile sound bliss. Absolutely amazing speakers! I already had the full RC setup from years back so I just got the bundle (the$700 one, not this one) to upgrade my RC-30s to the RC-70s.
Also, Martin Logans don't play nice with limp mode AVRs. Your best bet would have been the RZ70, 805, or DRX 8.4 if you wanted to stay in the PAC family.
The RZ30 would have been the equivalent to the 305 so you actually went backwards in power compared to your 505.https://www.zkelectronics.com/vsr...-vsx-lx505Also, Martin Logans don't play nice with limp mode AVRs.

I know I went backwards. I bought with the intention of adding an amp. That's why I moved the 505 to the theater room. I just feel like stepping up to the RZ70 would be a much better choice. Once I add an amp I will be to that price anyway.

I am curious what level of speaker you would consider an upgrade from the Infinity Reference R263/RC263 or JBL 580/590

If you have the speakers crossed over to a sub and you don't listen at ear bleeding levels, there is a 0.01% chance you'd ever notice one ioita difference between the RZ30 and the RZ70 or your current 505. So just enjoy your new system.

Make sure your receiver has your speakers on "small" with a 60-80Hz crossover, not "large" playing full range as often happens with many room correction tools' default post-calibration settings---single most common culprit in sabotaging perfectly good systems. If you already do, then you probably need higher impedance & higher sensitivity speakers to hit such high SPLs cleanly.

Basically same sonic performance with an extra $500 in your pocket!
