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.

  • The RZ30 bundle path can deliver strong value when paired with DIRAC calibration using a UMIK-1.

  • The RC-70 towers can sound punchy when crossed over properly, with the sub handling deeper 15-100 Hz content.

  • The RZ30 can include a full DIRAC Live license for 7.2 channel use, which supports future multi-channel expansion.

  • The speaker package can support a practical upgrade plan by replacing existing LCRs and reselling unused speakers to reduce net cost.

  • The RZ30 can sound lacking at ear-splitting listening levels compared with a Pioneer LX505 setup.

  • The RZ30 may struggle at very high SPLs, especially if the listening levels push beyond typical headroom.

  • The RC-70 towers can show real low-frequency rolloff and may sound boomy or strained at the bottom without a sub crossover.

  • The bundle may be a poor fit when 11 channels are unnecessary, since the AVR portion can feel like an overpay.

So I am interested to know why you would want full towers set to small?
if you set your towers to small and cross over at the recommended 80hz (or even a bit lower, maybe 60hz), your woofers can concentrate on mid-bass and upper bass regions (which will be kept tight and punchy without all the lower bass and sub bass signal) and then the sub can concentrate on what it does best (15-100hz) which is relatively non-positional. not only does it keep frequency response cleaner on your towers, lowering distortions and improving transient response, it also keeps them significantly more efficient because it takes way more power to make those lower bass frequencies than it does the high ones, this enables you to get somewhat more volume, lower distortion, keep transients faster, and overall integrates way better so you don't get bass frequency overlap with the sub.

I am currently running my rc-70's as large in a 2.0 configuration on my rz30 and I can't WAIT to get a sub. the low frequency rolloff on these speakers is pretty real - they're also ported so they tend to be a bit more boomy at the bottom... they CAN hit about 35hz, but the bottom tends to lack detail and I can hear it strain... I'm absolutely certain that adding a sub and crossing over at 70 or 80 is totally the move here and i'm working on making that happen. it's NOT just about the input power pushing to make those low notes, it's about the speakers design spec and driver behavior. if you have to push your drivers to do what you want in a particular frequency range, you're doing it wrong and you usually end up with distortion or boominess.

my current issue with a subwoofer is that my living room is part of an open floor plan with my kitchen, a stairway down to my basement (all open), and a short hallway upstairs so there's no way to pressurize it which means i'll need something really big if I want reference levels of bass in my room. thinking about maybe doing an 18" martysub but i'm still researching.

You might want to consider building or buying a mid-bass module nearfield and/or bass shakers as well. Hsu used to make an MBM but it's discontinued now, though the ULS-15 has an "MBM mode" and I think that one or two of the Rythmik subs also have an "MBM mode."

However, depending on your bass experience and expectations, a single 15" ported sub like a Hsu TN-1 or VTF-3 might already be enough, especially if corner loading works in your space. That would likely be the easiest most direct route. Or a pair of robust 12" ported subs, e.g. RSL 12s or Hsu VTF-2.

Tough question since there are so many options and factors to consider.

Upon saying that since you're new.
A very safe and budget friendly options.
I would suggest looking into are RSL & Starke, in that order.

Safest bet would probably be RSL's 10s MKii.
Its size makes it more versatile for optimal placement with good performance.
For a large environment, their 12s might be worth the extra $300.
They have good CS & return policy just in case you're not happy(very unlikely).

There are many other overall better options but would be more for people after specific performance, preference & expectations. That does come at a price though.
I bought the $800 speaker deal and rsl 10s mkii. Im having a problem finding a good deal on a receiver. I've seen advice to buy a used $200-300 receiver, which I've found quite a few options, but a buddy of mine said it's a crapshoot knowing if it's still good and to just go new.

I doubt I'll need anything more than a 7.2. What would you go with around a $700-800 price point?

With so many switching over to soundbars, you can run into really good deals with used.
Just looking in here you see how many people still recommend 5 year options like Onkyo's 7100, RZ50!
All you need is finding one with features you need.

A main reason those 5 year old units are still recommended is Dirac room correction.

A plus for Denon units is you get the game changing option for their room correction(Audyssey) called A1EVO.
It basically gives you the performance of the Dirac that's included in those two units for free!
There are many iterations, the easiest would be Express version.

I bought an onkyo rz30 that was a recent deal here. I think it was $800 iirc and I like it a lot. 7.2 includes a full dirac live license which is pretty fantastic, sounds good... it's 9.2 channels which should work out great for my end game (5.1.4), for now i'm running it as 2.0 until I can move around my room and get speaker stands and such.

i've thought about doing some bass shakers later on but those are really for like ~10-16hz for tactile bass. that'll come later. for now i'm looking in the 15-18" sub range. I don't really have a lot of space to go with 2 subs, I'd like to do a single large-ish sub which is why i was looking at the martysub. I don't really need more upper bass or mid-bass than my rc-70's can put out (they're honesty fine down to 40hz but the falloff is hard after that). because of my open floor plan, I'm not sure the rsl 12s is going to move enough air to get me to infrasonics with punch. the hsu-vtf-3 has come up in my research a few times, and I do like it, but i'm not sure if it'll quite be enough up to home reference volumes and down to under 18 or so. I'm still looking around. meanwhile something like a mini marty or the like is looking better and better... I don't really mind diy if I can get significantly more value out of it, but also I don't have any wood cutting gear so I can't easily do a full custom fab... flat pack, though overpriced, may provide what i'm looking for.
