Generally, you'll hear something at each xover point that stands out. By crossing them all at 80hz, you take a load off the AVR and it might open up the midrange. Crossing at 60hz might give you a better blend with the sub, a little more bass resonance in the dialog, more punch, etc....same with 40hz. Leave the surrounds crossed at 80. As long as you're not asking your speakers or AVR to operate out of spec, the right way to set things up is what sounds best to you.

By blending the bass together between the surrounds (5.0) and the Sub, you will avoid bass cut offs. Imagine if you will: you play one single note, like a test tone, all the way down from 120hz to 20hz. The note starts in your mains and slowly drops down through the range. At 80hz your sub kicks in as the mains continue to drop along with it. When you hit 60hz your mains kick out but the sub keeps going all the way down to the end at 20hz. I think we call this harmony. If your mains stop at 80hz and your sub starts at 80hz, there will be a clear break in the note as it switches to the other speaker.
It would sound similar to shifting gears in a car, for that brief moment, the engine is idle and the roar of the acceleration stops. This is why it works better to blend the frequency cut-offs throught the speakers to obtain gradual shifts in sound.
God I hope this made sense, it did to me while writing.

So I have the Onk 705...
RTi8 as my fronts
CSi3 center
fxi A4 surrounds
Incoming eD A3-300 sub

Anyway, my question lies when i run audessy...It seems it like to set everything at full band, turn on double bass and set the sub at 80hz (currently using an HTIB sub) anyway...What would you recommmend for these settings??

Im looking for opinions...yea, Full band is nice and makes everything loud and with the double bass it makes movies fun since i dont have a real sub yet..but it seems to cover up the center at times...so now im testing at the recommend 80hz...but if you have to choose or what do you have yours set at .... Thanks for your ideas...I know only my ears will make me happy but i can always check to make sure im not deaf...lol
post #3124 of 34757
Perfect sense! thanks for the visual. I just set the mains and center at 60 and the surrounds at 80. sub is set to 80. I will let you all know how it worked out.. thanks for all your help!

Very pleased with my new Polk speaker setup! I was sort of worried about how I matched up everything since I had to go small for the center channel and couldnt spend a fortune on the whole setup but after some demos last night I can say that everything is just wonderful. Here is what I have:

- Monitor 50s for the fronts
- RM8 center channel(took a chance on this speaker but size matters!)
- M10s for the rears
- Sony Powered Sub(I know, I'll get a Polk unit but it really is a decent sub)
- Blue Jeans speaker cable(mid-grade) all around with locking banana plugs

I tried some select scenes from Kingdom of Heaven(blu-ray), 300(blu-ray), Transformers(HD DVD), and various HD cable channels. Alls I can say is that this all completely blows away my old set of tiny speakers. More detail, more depth, much better soundstage presence, much more "in the room" feeling as well. The M50s really do help with overall bass output and the sub is now handling a little less of the bass work which IMO is a good thing. The sub takes care of the really deep stuff for good bass extension that before seemed to have a "hole" in the bass frequencies. I was getting good low bass but mid-bass was somewhat lacking/missing. Im still messing with the crossover freqency and will get that fully dialed in this weekend.

So, for mainly lower-end Polk stuff I am thrilled with the results and will continue to break these speakers in and tweak the levels. Just wanted to report back since a few guys were wondering how the RM8 center would work with the Monitor 50s..... well, so far so good.... nothing to complain about. Dialog is clean and during the few action scenes I tried the speaker holds up well to higher volume levels. The speaker is pretty small....but it handles itself quite well thus far!

I think I have finalized my set-up as of today (for now ) with a few changes in placement and stand upgrades. I will post the new pics tomorrow. I really like the new look and viewing is better now along with sound.

1) Created a platform on top of my TV stand to place my LCD on and raised it 4.5" also allowing me to move it to the very back of the stand. While fully reclined, the bottom of the screen is now at eye level creating a more dramatic effect and making the screen appear larger.

2) That allowed me to place my center on the top platform of the stand in front of and below the LCD. Center is now at ear height and performing much better thus far. Tested with King Kong HD DVD tonight.

3) With all shelves now free on the stand, I was able to move all equipment below the TV. Took the Audio Rack stand out of the room. Need to pick up a spacer of some sort tomorrow so I can place the PS3 over the HD DVD player on the bottom shelf. PS3 just creates too much heat to set it directly on top of other equipment. Lots of re-wiring required for this change in equipment placement.

4) With the audio cabinet out of the way and 18" more wall space, I moved the Fronts in closer to the LCD and moved the sub to the outside corner on the right side to increase the reflection points from the open side it was on at the left. The fronts being in closer actually helped the surround realism, I had expected quite the opposite to happen. But I really wanted to open up the entry way and get the sub into the corner.

It was one heck of busy first day of vacation for me, but well worth the time and effort so far. A much cleaner, less congested look with some increased performance to boot. I will try to get the new pics done tomorrow after I finish getting the PS3 set back up and clean up some of the wiring issues.


Thanks for the reply Ohio, but you really didn't answer my question. Will I really see much of an increase, switching from R50s to FXi5's for my surround? I like that the R50's are sturdy and the FXi5's would need a stand, making them likely to fall down in my current setup.

Seems like there are quite a few questions about setting the bass crossover, so thought I would pass on this link to a good overview article by Gene DellaSala at audioholics.
post #3128 of 34757
Question: Im currently running monitor 40's for my front and monitor 30's for the rears, in a few months i want to get monitor 70's for the front and move my monitor 40's to the back. I currently have an onkyo 605, will it have enough power to push those speakers or do i need something with more power?

My setup is similar, but my center is CSi-A4, and my sub is SVS SB12plus.

Anyhow, my current (still experimenting) setting are:
Fronts...60hz
Center...70hz
Surrounds...70hz

Right now the LPF of LPE (or whatever) is on 100hz been playing with that but not really noticing much difference wherever it is set. Of course I don't have double bass on since I changed my fronts from FULL Band.

I also prefer my surround FXi A4s on bipole over dipole. How about you?

Thanks for the info. Your link says: Shoot for setting the crossover frequency for at least 10Hz above the lowest frequency your main speakers can reproduce cleanly.
Where my confusion lies is Polks specs
Monitor 70's:
Overall Frequency Response: 30Hz - 25kHz
Lower -3dB Limit: 40Hz.
Which to set 10Hz above ? Overall freq or lower -3dB Limit.
In other words 40 or 50 Hz crossover for these speakers? As you can tell I am not really getting the Lower -3dB Limit thing.

The standard for specifying frequency range is where the sound level drops to -3dB from the "flat" response. I've always wondered why Polk publishes the -6dB points which will always provide a wider range and are misleading - since the acceepted standard for the frequency range spec is the -3dB point. That's the number to use, not the -6dB point.

Hey everyone. My local Crutchfield store has a pretty good deal going on the whole Polk line. Right now there's a BOGO deal on all their speakers (Its just a local sale) so I decided to give them a listen. I took some time to demo the various Polk offerings against competing brands in the same price range. The best speaker I heard from any brand was the LSi15 (the only LSi speaker connected in the listening room). Voices were very clear, and the highs sounded beautiful. Unfortunately I'm not an LSi guy, as I couldn't afford to drop even half price on a pair of those. I checked out both the Monitor series and the RTi series and I ended up with pairs of Monitor 70's and 50's to use as mains and surrounds respectively. I'm pleased to say that both the 70's and the 50's sound even better in my place than in the store.

OhioMike, it looks like I'm close to having a similar system to the one you put together. Any suggestions on a subwoofer?

A frequency response curve for a speaker should be fairly flat throughout the range. Polk runs a sine wave sweep in an anechoic chamber at a given volume. The graph looks like a hill rising to a plateau, then eventually dropping off at the top end of it's range. For the M70s, the FR probably flattens out around 45hz. At 40hz it's 3dbs down in volume, probably 10dbs down at 30hz. Below that it drops out of sight. So 40hz is +/- 3dbs. The +/- meaning that it's room dependent...some will get room gain, some won't, but the speaker should be fairly flat to around 40hz. Running this speaker full band with a sub crossed at 40, 60 or 80hz, may or may not benefit you depending on how the speakers interact with the sub at the crossover point. Same with running the speaker small with whichever crossover you choose. What's important is blending the sub with your speakers at the crossover point so there's no hump or suckout. You want a seamless integration. You need to download test tones and run them with a SPL meter to find out what's happening in your room. Avia is a great disk for getting you calibrated or there is available freeware that's has a bit steeper learning curve.
post #3135 of 34757
What kind of budget do you have for the sub? How big is the room including any openings to other spaces?
I am happy with my Velodyne, but there are much better subs out there. My room is also quite small, so it doesn't take much to fill it up with bass.

The 605 will be plenty, these are very efficient speakers. My 605 pushes an even bigger Monitor set-up without a problem.

Thanks mike. Killer setup. thats exactly how mine will be. I want 70's in the front, my 40's for side surround (which arnt that different from the 50's), and my 30's for the back.
post #3138 of 34757
@ skipsterut and Ron Temple. Thank you for the clarification on the -3dB limit. I actually spent time on google looking for the info you gave me. I will give your suggestions whirl when I get a chance.
post #3139 of 34757
These look to be essentially the same price ($100). It seems the CS1 is a higher quality speaker. I'm confused.. Anyone know the difference??

Thanks for the reply.

My room is about 15'x10' and I have pretty strict budget. On my short list for subs are the AV123 x-sub, and the new Tweak City audio SCAMP-10 (whenever its released). I can't easily stretch past $300 total.

Since my room is smallish, I think most subs will do a sufficient job. I just figured I'd ask to see if anyone has better suggestions.
post #3141 of 34757
Very good. Your budget is plenty for a sub in that space. The Scamp is certainly the flavor of the week. The X-Sub has tremendous reviews and of course the Bic-H100 is always a good choice.

If you can wait, the Scamp 10 would be the choice. Early reports is that it will be a very musical with better performance than the x-sub. A pair of these will be on par with an SVS PB12NSD for output for about $425 all in. I believe they are about 60-75 days out.
post #3143 of 34757
Thanks for the advice guys.

I'm pretty happy with the Polks. Before I found them, I was planning on demoing an Aperion 4B system. Unfortunately the Aperions have become a bit pricey and for the price of a pair of 4Bs, I picked up the Monitor 70's. I still may try out the Aperions, but I have a feeling that stepping down to such a small speaker would not be much of an upgrade.

Hallo Mike and Everyone,
Finally I received all my speakers and put them to work.
front-monitor 60's
center - csi1
sourrands - monitor 50's
back sourrands - fxi3
sub. - polk psw111

Works great.
I ran audyssey yesterday and of course my onkyo 705 set it up - everything as a full band.
Any suggestion for crossovers ???
I was reading a few posts by OhioMike yesterday and in one of it he left averything as a full band.
Next, He changed just center one ( I don't remember it was 60 or 80hz)
So, Mike did you like it ??? any suggestions for my settings ???
post #3145 of 34757
I think adjusting the center to 60hz really brought the dialogue back out of it. With the CS1, you should be good at 60hz also...but may want to go to 80hz with the smaller drivers, check them both out..but 60hz should be good. The 60's should work very well in full band. The 50's can also go full band or 50-60hz if you like. Put your rear surrounds to 80hz and you should be ready to go. The 50's as side surrounds are pretty great, aren't they? How is the PSW111 working out so far? A good test for it would be the Two Towers, when they are launching the rocks and the wall explosion. When the large pieces of rock from the wall explosion land, you're walls should be shaking and your floor rumbling if it is hitting low enough. Also the Ironhide flip from Transformers should rattle everything on your walls....good stuff!!

Got a chance in my boredom today to really test out the set-up for music and was extremely impressed. My main listening is Modern Rock...so I had tested it out with NIN, Korn, Sixx AM and Linkin Park, even some Bob Marley (Legend..one of the best discs ever made). But today I turned to my 2nd love musically, Electronica, to really test this system out with the overwhelming digital bass.

The 70's on their own were extremely good in the mid and deep bass, especially the mid hits, extremely tight hits and the deep bass was clean and more powerful than I expected, easily sending vibrations throughout the whole house with the HT sealed up.

When I added in the DPS-10, I was amazed by it's performance, so much more than I thought it could do. Very tight and quick excursion and inversion. It was able to keep up with Voodoo and Serano's: Blood is Pumping, which if I remember correctly back to my DJing days is around 142 beats per minute, one of the fastest tracks out there. The 70's were fantastic in recreating this difficult track. For those who aren't familiar with this song, it was in either Blade's blood bath club scene or Blade2's club scene (can't remember which, I have the track on a 2-disc German set) I'll have to check which one it is tonight.

Also on the list: DaRude-Sandstorm (incredible): Zombie Nation-KernKraft 400: Gigi D'Agostino-I'll Fly with You and Bla Bla Bla: and Dido-Thank You Remix. I really wanted to test DJ Jean's-The Launch, but couldn't find my disc, think it's in the car.
If you are into this music and have any of these discs (if you've never tried this genre, for 10 bucks they are worth a listen) give them a try as they will really let you know what your system is capable of.

Music is the very reason I bought the 70's. I was tinkering with the settings as mentioned in the above posts. Changed what Audyssey did from the full band.
Center CS2@ 60Hz X-over.
70's@ 50Hz X-over
50's@ 70Hz X-over
30's@ 70Hz X-over (Audyssey set)
Sub PSW110 80Hz X-over(yeah not a great sub)

Was listening to Santana Essentials while in the setup mode in the Onkyo and turned off Audyssey by chance and the whole system basically came alive. Lots of rich clean sound, good bass and good volume. Didn't change a thing just turned off the Equalizer. Flipped over to PLIIx Music even better. Make me wonder that it set most of my speakers to full band and set the filters (or those 100's of parameters that Audyssey sets) for that range. Long story short. Seems Audyssey is choking my system more than filtering it. Could be way off here too. Maybe THX amp. My Sub probably doesn't help matters either.

To tell you the truth I din't have so much time to test everything.
Seems like 60's and 50's as side surround - works great really big difference to harman kardon in box HKTS18.
I am very happy with them and thank YOU for all suggestions before buying them.
Tonight I will work out with subwoofer.
Looks really beautiful. Seems like well build and looks nice , but we will see how is it working in overall composition.
Maybe You will tell me how to test it good ???
post #3149 of 34757
I am just affraid that Polk Psw111 can't produce so much bass, but reading manual it can, ah we will see.
If it can't maybe I will exchange for something different like valodyne.
I wish HE can because I don't like returns
post #3150 of 34757
A ha I forgot about one question.
If I change only center for 60 or 80hz as You recommend do I need any x-over in my PSW111 ???
