onkyo 607 2 subs vs 1

slowpolky

so for 2 to 5 hours of movie going im not gona fry the ps3 on the rack above or melt the vynal on my fixed frame screen .Did you see the rack its going to go on though? the marantz rm 7001 from amazon

I assume it's going on the bottom shelf? That thing is going to have PLENTY of breathing room there. I wouldn't even worry about it the slightest bit.

Melting the screen? It would have to be pretty damn hot to do that. The Onk's run hot, but nowhere near hot enough to melt vinyl. They average around 130 degrees or so after being used for an extended time.

It'll have tons of breathing room on that shelf though...so, like I said, I wouldn't worry. After you get it, keep your eye on it for a while. I highly doubt you'll have any issues with it overheating.

My cabinet is FAR more restrictive than that, and it's never overheated after listening to music at high volumes for 5-6 hours at a time.

thats very relaxing because i love that rack ,you do know its only like 17 " in height? . i thought ,hmmm if its 2 hot i shall place it on the top shelf because some1 said there onkyo melted the lazer on there dvd plyr on the shelf above it , but if it was sitting on top could 130 dgrs 5 inch below my screen cause it to sag or melt?

Hi Slowpolky,

I said that. It didn't melt the player itself, just knocked out its laser--overheated it! A PS3, I have one, can stand on its side. So why don't you consider standing it up on top of the unit and letting the Onkyo breath on its own on the very bottom shelf with LOTS of space above it. The only way the Onkyo will melt something is if you put it directly ontop of the back right side of the unit itself. That's where most of your heat is generated, the rest of the unit is not as hot in the front!

yeah, the bottom shelf is what i had in mind and wanted , plus i do like the idea of the ps3 on top of the rack as itl mch the silvery crome thing on the rack

Just for reference, here's where my 606 sits.

The back of the shelf is closed in the back, aside from an opening for cables that's about 4-5 inches wide and runs the whole height of the unit. It's got about two inches of air space above the AVR, and less than an inch on either side. If I'm not having overheating issues with this shelf, you're not going to have any with the one you ordered. Your rack is like the equivalent of the Grand Canyon compared to mine...lol

I would like to give my 606 a bit more breathing room though. A new rack will hopefully be coming along a little later in the year.

This is what I'm gonna end up getting.

never thought i would say this to another man, thats a nice big rack dude lol, thats a very cool store though. I shopped there myself 3 month ago ,i bought the wood technology solid hardwood ebonys ,18 inch centre and 21 inch for my front l/r and i must say that for the black rti's its a match made in heaven , almost seems like they were made just for them speakers , i picked up a pair of the sanus bf 31 inch for my fxi3 , they have super fast delivery and let you return it without payin shippin should you choose to do so

I have run two subs and in my room its an improvement but placement is a bit tricky as well as sub matching. I had mine at opposite ends of the room at a diagonal but that won't work for every room. And as Curt says and I have to agree ONE may be enough. The subs can interfere with each other if you're not too sure about how to configure and place them?

What is your opinion on running cable from your receiver to the sub, then from the sub to your speaker, thus avoiding the crossover. Heard it on AV Rant...

Well for HT...why would you even want to do that? LFE effects are their OWN .1 channel and that means you would have to tell your receiver it has no SUB attached to it. Now sure you can get bass in 2 channel that way....but LFEs are a separate channel of their own.

I would only do that if I were dealing with a 2-channel system..and even then I'd probably just want a pre-amp that had a sub out on it (or maybe 2 channel out).

Finally, depending on the sub....for some subs that means sending the power through the subs amplification to the L/R which are now attached to the subs...not the receiver or amps DIRECT POWER. And that's got to add some noise, I would think?

Also, a REALLY good receiver or Pre/pro should have BETTER bass management than most subs...except perhaps a high tier sub?

I'll stop here....and let others add. It's not like there aren't a lot of other takes on this besides mine.

I hear you..Actually the suggestion was made by someone at Polk to the host of AV Rant..the host didnt like the idea.my cheap Sony sub is 100 watts. Always wondered what the speaker inputs were for in the back of the sub, being that Im a novice at this game.

I'd like to chime in regarding the comments and thoughts provided on the Onkyo "600" series of late, beginning with the model that this company brought to the current state of surround decoding (i.e. TrueHD/Master Audio) and the one I went with, the '605...

While the lack of preouts is indeed a slight shortcoming on these models, an external multichannel amp is not really necessary with these Onkyos; I have owned a plethora of models in this series, beginning with the '600 years ago, and none of them really needed a power boost. In fact, I was running a '600 (80 watts x 6) in my parents' home theater for them at the time and that room was HUGE, with 15 foot vaulted ceilings and such...the power of that '600 could be experienced in other rooms of the house when the volume crept up. Sure, these receivers won't power a movie theater...but the "90 watts per channel" rating of the newer models are really deceiving IMO...

As for Curt's description of the '605/606/607s being "entry level" models from Onk, in a very literal sense this may be so -- even though there is a model or two below these units that don't decode the new formats -- but I disagree in the sense that they don't really perform IMO as "entry level" models and their wattage ratings as I said are deceptive. Furthermore, the build quality, features, etc. take them out of that moniker range as well; perhaps "the first level of Onkyo's better-made receiver equipment" is a better yet less traditional way of describing where these '600 models reign...:D

As a side note, these receivers REALLY come to life by using Onkyo's "INTELLI-VOLUME" system that can be found in the setup menu's SOURCE SETUP submenu; this control, while intended to "level off" the different devices connected to the receiver in terms of their input volume, can be used very much like a power amp's sensitivity control (which is the way I use it) in that the higher you crank this dB number, the louder the input connected "appears" to be at a lower volume number...the range goes from -12dB I believe to +12dB, and I keep all my IntelliVolumes (well, the DVD and CD inputs) on "+10dB" which makes films and music seem much more alive and punchy. The downside to using this control is that ANY change made in these receivers that involves pushing values into the "+" range -- such as IntelliVolume and the speaker calibration levels -- reduces the overall maximum volume value for the receiver. So, for example, if I use "+10dB" on IntelliVolume for the DVD input, that AUTOMATICALLY reduces the maximum volume on my '605 to "90" from the factory-set "100"...

But I prefer this because of the "power amp sensitivity control-like" punch I get from cranking up the IntelliVolume...
