Axiom Home Page Forums General Discussion Advice from Axiom Owners One Last LFR Question

I'm strongly considering the LFR660 now (even though Mojo was pushing me toward a larger speaker*) and had one final concern - will the fact that I'm placing the speakers only a foot or two near an opening on the rear muck up the rear DSP processing?

I've tried to attach a diagram, but if it doesn't work what I have is basically the common foyer to living room large opening with 3 or 4 feet on each side. The speakers will be placed on those 3/4 ft walls and open to the foyer.

No, just your bass response will be different than a solid wall.

With toe in you will be sending rear energy into the corners and it will make its way to you as designed.

Putting that opening behind you would be much better though.

I’d call axiom on this but I think your ok. My understanding is that LFRs need walls directly behind them and to the side to achieve the widening of the sweat spot. The key word here is understanding ... before buying I’d find out for sure.

What kind of a room is THAT?!*

If that is a half wall opening, sitting there would be better as Trevor said. You could also place your couch symmetrically
between the speakers.

Regardless of which way you go, you may want to place sliders under the speakers. That will make it much easier to move them around so you can eliminate position error. The 660s will be more forgiving of position error than the 60s.

No matter which way you go, I think it will sound very good.

Cool, I'm glad it's at least a reasonable placement.

I have spoken to Axiom with that drawing and they said I'm fine. But they also said the M80 was fine and you guys had other thoughts; so ... I thought I'd run it past you all.

Sliders is a great idea, which to be honest I wouldn't have done. But I will be moving them around a lot at first so good idea.

I can't switch the direction, at least not until it's my wife's idea. A deal's a deal and that's my wife's room for decorating. I got family room and computer room (M5's and M5's); she got living room and dining room. She carved out some space for the speakers so I'm happy. I could also use the middle of the long wall (there's a fireplace there that's not shown); but I think I'd prefer the long listening placement. Also, I didn't think symmetric between the speakers was as necessary with the LFRs? No matter though, it's not as offset as it looks, so I'm not too worried about that.

Thanks again for the feedback!

Sure the M80 will be fine. It will produce sound, with more SPL than you can handle. But I still maintain the 60 or 660 will sound better. They are apt to deliver more linear bass and acoustically disappear better.

The long wall is usually discouraged for bass reasons. My living room, same size as yours, is set up on the long wall and I love it although bass was a real challenge. The 60 and 660 would be great in that department. Expect a hugely wide and enveloping sound stage on the long wall and awesome mid-bass, particularly with the 660, even at low volumes.



What I can't tell you is if the 60 or 660 would disappear as well on the long wall. My M100s, active LFRs and M80s could not. The M50 and M5 bookshelf were better. The M2 bookshelf and OW completely disappeared and so do the M5OW. I give a slight edge to the M2OW actually.

Completely agree here, with emphasis on the M2OW being the champ of on walls.

Rebulx, I agree with you too!

Your room looks bigger than mine Mojo, maybe it's the bow window, or maybe it's the lighting. But in my case I think using the long wall would limit how much of the room get good sound; but who knows, maybe the LFR would reduce that problem too. (Nice room by the way! And I didn't know you played an instrument. That automatically gives you more acoustic cred.)

FWIW, Axiom did say the LFRs would be better; but it was more because they are LFRs, not because of sizing problems.

I've noticed all the discussion of the on-walls elsewhere, and it's caught my eye. I love listening to music in all-channel stereo, and that's because of the enveloping 3D effect. But of course it's also a little acoustically inaccurate. I'm hoping the LFRs gives me the enveloping feel, but with more accuracy. But if that fails, I'll be looking to add on-walls (or maybe in-walls) in the rear. But that's well down the road.

On walls are much better than in walls. Hugh difference.
