Axiom Home Page Forums General Discussion Home Theater M80's big for 10'x19' room? Drivers hitting frame?

Hi there!...finally got a projector..so I am moving my speakers to the room it will be in.

I am wondering if M80's will be too big for a 10'wide by 19' long room.

I wanted to use a 100-105" wide CIH size AT screen.

Another questions is that the lower part of the screens frame will be in front of the lower drivers. Somewhat inbetween the bottom two. Will that be bad?

Should I just get 3 m22's instead?

If I used a 88-92" diag 16x9 solid screen, the m80's would only be about 7 or so inches away from the side walls. Which is why I was going to go AT. That's doesn't seem like proper breathing room? It would also leave me with a pretty small 2.35 scope viewing area. I wouldn't mind having the option to have that sweet 105" wide scope movies :).

I am sure I'll have more ?'s shorty.

Thanks everyone !

I wouldn't worry about the position of the frame in front of the lower drivers--lord knows mine get obscured half the time... Also, I'm not a believer in "too big for the room" when it comes to speakers, except in physical dimensions. If you can take that (look at a side view of an M80 to see exactly how deep it is+breathing room), then I wouldn't worry about it.

My view is to forget the so-called "acoustically transparent" screen, which isn't ideal for either sound or picture, and go with the second screen that you mention. Having the M80 woofer cones very close to one room surface is okay if their distances to the floor and other wall differ. So, I'd suggest the M80s outside the screen and a vertical M22 beneath it for the center channel.

I did a lot of research a year ago into screens and projectors. Despite a good effort, I couldn't find any data or supporting opinions that made me comfortable enough to go with the concept of an acoustically transparent screen at that time.

Everything Murph said, I had the same issue!

Liquid - check out my pictures for a similarly sized room. Mine is around 14' wide, so a bit wider, but I've managed to squeeze 2 M80s plus an EP800 + EP600 in the front of the room. My screen is in a 16:9 format and is 92" diagonal.

So, are two M80s too big for your room? Not even close.

As for the questions about the screen... I agree with everything about the transparent screens. I'd forget that idea and go with a regular screen. You could consider a wall mount of a VP150 as well, which you can also see in my pictures.

how tall is your room? You can't raise the screen up enough for the 80's to sit below? Keep in mind if your going to have 2 rows of seating you don't want the people in the front row to block the back row viewing.

Hello hello,

First off, as always...thanks for the help

The majority thus far are against the AT! Interesting.



So with screen 2 it would be
(Wall-7"gap-M80-Frameleftside-framerightside-m80-7"gap-Wall)
M22 center channel.
The m80's would have about 12 or so inches behind them before the rear wall, and 7" to the sides, on both sides. Maybe less if I ever GG, Doubledrywall, decouple, etc...

This is definately okay? Just seems sooo close.



Hi Jason, I saw your room...Love it. I would LOVE to have 14 ft wide room. To me, it looks like your speakers have proper breathing room. I'm without those 4 feet that your speakers are hanging out in That's what made me think AT...to get the speakers away from almost touching the side walls.

But, no one mentioned speakers almost up against the sidewall being too bad..So maybe I will give a regular 92" screen a go.



You know...I was wishing Axiom made a speaker like the Klipsch THX just so I could do this! My room is standard 8 feet tall. I am pretty sure that the screen on top of the M80 speakers will be too high. I will remeasure and evaluate this option. Maybe I can tape 2 M22's together for each left, center and right I know I've seen some of you making frankenspeakers before :P.

I live in Warrenton VA. and I have my speakers (M80's) fairly close to my walls (11' wide room). You can come check out how they sound if you like. I have pics in the gallery under "Roger's Theater":

Just posting a quick reply (I'll admit I didn't read every reply).

Unless you go with really (and I mean *REALLY*) expensive screens, and then you run into issues of matching a high performance projector to that screen to "compensate" for the acoustically "opaque" (not really transparent) screen. I would skip the idea personally. As for the M80s, let me tell you about my speaker choice path.

I started with M22 fronts and VP 100 center. When talking with the folks at Axiom, and we talked about cubic feet (volume of the listening area) I bumped up to M60 fronts and a VP150 center.

That was when I was really set up in a non-dedicated area. Now, I am in a 10' x 15' room and the M22s would certainly do the job, but I don't ever feel like my M60 fronts and VP150 are "overkill". Heck, the M60s would work wonderfully in your size room as well, but why not go for the M80s if you are looking at them anyway. They will be amazing for you.

My room is about 11 X 20 and I don't feel as though the M80's are overkill. The reason I went with the 80's over the 60's is that I can play them at lower levels and still get amazing detail (I live in a townhouse and can't play movies too loud too late).

Liquid, do you already have the M80's?

I have 9ft ceilings and a 10ft wide 2.35: 1 constant height screen, 51"tall x 120" wide. My 80's are currently on a stage up front so they won't fit underneath, but if I was not on a stage they would fit fine. Not sure about 8ft ceilings.

What is important is that the drivers are not the same distance from the side walls as they are from the back walls. Plus, you could toe-in the speakers slightly anyway, which works great.

Yes, those distances are okay. Keep in mind that what we're talking about is the distance to the center of the woofer cones, not the distance to the closest point of the enclosure. These distances should differ so that the reflections from the nearest room surfaces don't all pile up at the same frequency, causing a significant peak and valley in the response.

By the way, "breathing room" is most often applied to the distance necessary for the speaker ports not to be significantly affected. Alan has pointed out that a few inches are adequate for this, so the distance that you mention from the wall behind would be no problem from that standpoint.

I do appreciate that offer! Wish I could take you up on it, I live in Las Vegas now. I should update my profile. Seriously though, thank you again for that offer. I do already have the m80's.



Ah ok. Then that would work for me. Looking at your sweet sweet scope screen really makes me want one. If the screen on top is too high up... I may have to trade in my m80's for something that would fit under. Then I'd end up with the issue of the tweeters potentially being too low? I dunno... I will probably start out with a 16x9 screen for now since I do not have a anamorpic lens anyway.

To expand on the speaker idea... could I use double m22's l/c/r to get closer sound to the m80's? Or just silly talk? Sounds kinda like silly talk :(. It would be nice of axiom to release info they are gonna make a big ol stumpy double wide box speaker :)! I don't want to try out the Klipsch ones...



Thanks for that info. That does add a few inches of clearance then Alright..so I got it now.
Distance from sidewalls the same = okay.
Distance from the sidewalls the same as distance from the back wall = not okay.

Once again...thank you all so much for taking the time to write such thorough responses.

My M80's sound great and my room is not much bigger. (2150 cf) However, it does open up to a kitchen and a hallway.
