Projector screen, most impressive. How big?

Anyway, the receiver is fine, the Speakers however, are to small for your room. At a viewing distance of about 20 feet, those cheap little speakers are going to be straining and may even blow depending on how loud you run your movies. And the subwoofer at 110 watts, your probably not even going to notice it's even on. I recommend at least 250 watts for your theater room.

That speaker system is made for small rooms, about half the size (probably even smaller ) of what you have. I recommend investing in a larger speaker system.

Of course this is just my own opinion.

My room is pretty much the same as yours. I run JBL horn driven speakers for my mains at 150 watts a channel, and 2 passive 250 watt JBL subwoofers powered by an external 500 watt Carver stereo amp. I'm actually looking into replacing my current subs with a folded horn sub, that only uses a fraction of the power my current subs demand.

120" screen. What do I need to check when matching up speakers to receivers? been checking on the internet and almost all the websites say that I just need to match up the impedance of the speakers to the receiver.
Your speakers and subwoofers sound expensive. Was going through the local electronic shops and most subwoofers with that kind of power cost around 1k usd.
Are you on 5.1 or on 7.1. What happens when you play 7.1 dts hd Master through a 5.1 setup? or plaaying 5.1 through a 7.1 setup? will the side sorrounds remain silent?

Most all receivers will say what the impedance is or whether it has selectable impedance. My gear is selectable between 6 and 8 ohms. All impedance means is how much voltage is going to the speakers. If you use 8 ohm speakers, and use a 6 ohm impedance setting on the receiver, the voltage will ruin your speakers because 6 ohms utilizes more voltage. I wont go further into that because it gets really technical.

The speakers that come with the box set you showed me are to small for your theater room, and most likely they are 8 ohm speakers. They will be straining with the volume levels your going to be playing at especially with a 120 inch screen sitting 20 feet away. I recommend getting larger speakers.

About My subs, they are passive, they are not powered. I have to use an external amp to drive them. The subs them selves were very reasonably priced, about 400$ each. The speakers LOL, I cant remember what I paid for. It was either 200$ for a pair, or 200$ each. The speakers by them selves don't sound very good. I had to invest in a Equalizer to tune them. I also had to borrow a RTA device to set the equalizer.

My set up is only 5.1 because there is hardly any 7.1 material available. I have a couple 7.1 movie titles, but I'm not worried about upgrading at the moment.

What happens when you play 7.1 through a 5.1 set up? When you set up your receiver, and hook every thing up, you either set it up for 5.1 or 7.1 ( depending on how many speakers you have )and when you play a 5.1 title, it only plays in 5.1, and when you play a 7.1 title, it will play in 7.1. A 7.1 title playing through a 5.1 setup will down mix the extra surround channels into the standard surround channels. You wont loose any surround FX, it's just been mixed in with the standard surround channels.

Man you really do know your stuff. What receiver are you using if you don't mind me asking?

I think getting a powered subwoofer is the way to go. Im trying to eliminate the complications that come with passive subwoofers. What are the disadvantages of using different speakers from different manufactures. If the receiver that I plan on buying will have audessy eq? Is there a chance that the sound will become unbalanced?

Im willing to spend up to 1.5k usd on the receiver and I have been told that yamaha tend to build future proof AV's. been checking on bookshelf speakers and I find it absolutely ridiculous that a pair of high end bookshelf speakers cost 1900 dollars a pair.

Don't worry about passive subs. You're not going to find them sold in any store now days. I had to special order mine.

Mixing different speakers from different manufacturers in your theater set up will ruin your surround field. Regardless if you are using Audessy EQ. Audessy does the EQ itself and the problem with that is Audessy cannot tell whether or not you have a speaker by a object that will can cause an acoustic problem when it does it's room EQ analysis, and add that problem in the reading. I don't recommend messing with equalizing your speakers, because it can lead to great frustration if you don't know what your doing. I have equalized commercial systems, and let me tell ya, it was a trial and error process until I started to understand what was going on. If you have ever been to a theater when the sound was shrill or dull sounding, or both, then you have heard bad EQ, and the acoustics are the main reason of that.

It's best to just use the same speaker for every channel, that way your sound field will be balanced. 1900$ a pair of speakers, lol, I would never do that, but thats just me; However, I have listened to a 20,000 dollar speaker system though.

I run a Pioneer Elite receiver that has preamp outs, connected to external amps. I don't use the receiver's built in amps. This kind setup is called a sperates based system. I use Marantz Amplifiers for my 5 mains. Processors alone are too expensive so a receiver with preamp outs is more affordable. user added image

I never understood why get large speakers if the subwoofer can handle all the LFE effects been going through some images on the blu-ray.com website and many if not all have large speakers for the front and centre speakers. I think bookshelf speakers are the way to go for all the speakers

McIntosh is a really good AV company. I have never had the chance to sit down and listen to any of their speakers, but I'm sure they sound really good. The 20,000 dollar speaker system I listened to was from Snell acoustics, their first THX certified model. This was back in 1995 ( the Analog days ), when Laser Disc and Dolby pro logic ruled the AV world. The Snell system compromised of 4 very tall ( taller then the McIntosh ) tower speakers, and a GIANT center channel that had tons of drivers all over it. It was as big as a 40 inch TV. The surround speakers were taller than the front towers, and where dipolar due to the THX specs. The subs where passive with 18 inch Drivers and where powered by 2 huge Mark Levinson amps. Everything else was ran using AV gear from Pioneer Elite ( laser disc Player ) and Proceed ( processors and amps ). I was auditioned a couple of demo AC-3 5.1 Laser discs from The Eagles and from Fleetwood Mac. My god, sound quality was as if they where preforming in the room live, and this was almost 20 years ago. Later that year I got to demo some of the very first AC-3 5.1 Laser discs ( True Lies and Star Gate ). They didn't sound as good as the music discs did. It was due to a bad 5.1 remix for video at that time.

Now I only told you what the speaker system cost, not the entire system as a whole, which puts the McIntosh system to shame.

About the McIntosh speakers. The Article said that the speakers "Natively" only went down to 30hz, and said that McIntosh didn't make a sub woofer. And besides all that they crossed the speakers at 80hz.

Towers vs. book shelves, it depends on your tastes and your room setup. Some people don't have shelf's for bookshelf speakers, but have room for floor standing tower speakers.

Finally got this receiver. I did some tests on it at the local yamaha shop with Transformers dark of the moon (the only copy that I have that has 7.1) I was really impressed.now all that's left is to look for good speakers. The receiver only costs 700 usd so the left over budget will be pushed towards the subwoofer

Nice Choice! Too bad I'm not a fan of Bayformers.

If you have any more questions just give me a shout.

For me nothing comes close to bayformers in terms of audio quality not even master and commander

Yeah, the sound mix for Bayformers is top notch. I think the last Pirates of the Caribbean movie is 7.1 also. The newly remastered Jaws release on Bluray is 7.1 also. I think the Indy trilogy coming up on bluray will be 7.1 also.

time to pick out a subwoofer and in all honesty i know nothing about them other than you should stay away from passive subwoofers unless you know what your doing. Been checking on subwoofers and i think ill start off by asking what is the difference between watts RMS and watts dynamic power output. Do you think this is a good product

The RMS is the subwoofers continuous power. The dynamic power output is the maximum power output. The subwoofer you linked here in my opinion is a complete waste of money. They want 3000$ for a 200 watt sub with one 12" driver, and it only goes down to 29hz. Any good sub should go down to 20hz. 3000$ should get you state of the art, and that sub in my opinion is not worth it.

Again, You shouldn't worry in the least about passive subs, they are not an easy thing to get, and your not going to find them at your local best buy or wal-mart. I went Passive because the powered subs sold here in the U.S. ( In my neighborhood to be exact ) suck. Way too boomy and the internal amps where not very good quality. So I ordered some Professional JBL passive subs that have to internal amplification.

Ah i see. Still, I think you could do better then that for even 400$ Alot of the powered subs I see today are at least 350 watts. They may not have good amps or go that low but you can still do upgrades that will improve the performance. I replaced the internal wiring in my JBL's to improve the frequency response, and because I use a separate amp do drive my subs, I'm automatically getting better performance than I would, had I went with a powered JBL sub.

Also in choosing a powered sub, take note that there a different kinds. There are the sealed models and there are the ported or vented models. The sealed models will have a flatter response and will go lower, but require alot more power than a ported or vented sub, but aren't as loud as ported or vented subs. But ported or vented subs are subjective, they usually dont have as smooth of a frequency response or go as low as sealed subs ( this is due to how well it's tuned via the ports ). However, ported or vented subs play louder than sealed subs, but there are exceptions to both ported and sealed subs, it depends on how well they are made.

My passive JBL's are ported.
