Sony's will be fine for surrounds.

Is this for home theater or music? If for HT are you getting a matching center for the Monitor 70's?

CS2 is actually the matching center for your Monitor 70's.
http://www.newegg.com/Product/Produc...-212-_-Product

CS10 or CS20 would also work but actually made to match the TSi speaker line. Tsi is basically a Monitor series speaker in an upgraded cabinet.

That's not small. perfect size for my your new Polks.

17 x 12 is slightly larger than my living room which has 4 tower speakers.

I would NEVER recommend mounting a floorstanding speaker on the wall. That'll look diifferent having a 15" deep, 42" tall, 47lb speaker on the wall. at least it'll be a conversation piece once you figure out how to mount it.

By mounting the M70 on the wall will destroy proper ear level of the speakers when you are seated on a couch

Its recommend the speakers tweeter be at ear level with you are seated on couch or chair

Mounting a Monitor 70 on a wall would not be innovated but it would land you the idiot of the year award

If you don't have the space for large speakers quality book sheleves with a quality woofer would do just as well

But other than it looking weird, you don't think it would affect the audio aspect?

The 70's are already designed to output sound at an optimal height when placed directly on the floor. If you're looking to wall-mount speakers, then find a set of bookshelf speakers instead of the 70's.

Better yet, if floorstanders really aren't an option, buy three matching bookshelf speakers, and use them for the entire front soundstage...

Just know that you will be losing a lot of low end extension if you go with bookshelves over floor standers. For HT, its pretty crucial to have a sub woofer, so if you do go the bookshelf route, I add a sub to the list.

The Polk Monitor 40s and CS2 would be a nice front three if going the bookshelf route. I would suggest the BIC America F-12 sub to accompany them (in keeping the components at the same value level)

Living Room
Samsung PN60F5300 | Denon DBP-1611 | Roku 3
Denon AVR-1713 | EMP E55Ti | EMP E56Ci | EMP E5Bi | BIC F-12

Computer
Topping TP23 | NHT SuperZero 2.0 | Velodyne DEQ-8R

by the looks of that picture, you're better off with wall mounted speakers. Go with one of the recommendations above like the Polk Monitor 40.

No it doesn't matter. Your Onkyo 707 doesn't put out 125 Watts per channel anyway so it doesn't matter if the Monitor 70's can handle up to 270 watts since you have no source that can provide that kind of power.

I suggest perhaps looking at the LSi Bookshelves. Those speakers can take some serious wattage. There is a guy selling a set of LSI9's for 325 on the Polk site...they wont last long there....also Polk has an Ebay site you might find some deals on (like for the matching center)

LSi9's are 4 ohm speakers. I wouldn't recommend getting those without some type of external amplification. They're very power hungry and I doubt the 707 will provide enough power to make them truly sing.

Stick with the Monitor 40's.

Yeah, I forget if its rated for 4 ohms...I just know it was one of their higher lineup models......

If I had 325 bones for those I would be all over em.....

OP, I think 125 watts is fine for your fronts. Keep in mind most recievers really dont provide their full rated wattage to the speakers. They normally say at the back of the manual that its 90 watts per channel with two channels driven.

So if you get a external amp (later on) that does 125 watts with all channels driven then you will fine.

PS. I used Monitor 40's in my bedroom w/ a CS1 and a crappy Sony reciever for 2 years and was more than happy, so the 40's can be used as fronts with no issues at all.

Just make sure you get a good sub to fill out the bottom end of the spectrum

My Setup

don't worry about any external amps right now. You have no room for one! Get your monitor 40's and CS1 center. The 707 will be fine for your room.

Bigger than your Onkyo 707 and will need room to breathe. The XPA-3 is 57lbs!

nice sony subwoofer ...isn't that an oxymoron? Just kidding! ;-)

Please keep in mind that the M40's are rear ported and need to have space behind them; don't push them up against the wall. And try to get them as far apart as you sit from them.

Oh there's plenty of room for towers in there. Just push the mini fridge and computer over and you got it.

BTW, I like your office/man cave better. Sledgehammer are you serious!? Win!


5 Infinity Beta 20's all about 3ft from listening position with Infinity SW-12 sub and Pioneer VSX1014. I think the room is 12x14.

They did not have any of the monitor series.

You did fine and should enjoy that system very much. I would highly suggest though spending some serious cash on a good sub. This will make up for the areas those speakers will not work well in (bass)

If your Sony sub is like my old SA-WM40 you can add some polyfil to help eliminate some of the boominess and tighten up the bass. A very cheap fix, maybe $5.

Alot of us did this several years ago.

I like these mounts better....they are what I am using for my Monitor 40's and work great: http://www.amazon.com/Pinpoint-Clamp.../ref=pd_cp_e_0

Also drop some industrial strength velcro rather than use the included screws and you will be fine...

You'll be fine with the way the speakers are. Where is there room for bookshelf anyway?

How do they sound? It has to be way better than what you previously had.

But are they capable of doing 60hz well? As well as a subwoofer? 80hz is better for those speakers, the specs may say 55hz but bass starts rolling off way before then. Let your subwoofer handle the lower frequencies because it'll do a better job than your bookshelf speakers. It'll also take a load off your receiver since it doesn't have to produce the lower frequencies.

The THX recommendation is also to cross your speakers at 80hz.

the crossover setting isnt an instant stopping point, its where it starts to roll off, so with an 80 setting it still plays below that, so if you set it lower then it usually ends up being too low
