Axiom Home Page Forums General Discussion What's New At Axiom Introducing the M5 and QS10

Thanks again, dude. I thought the on-wall speakers were much thicker than the 4.75" stated on the product page. Your suggestion just might work. I'll do some measuring with a caregiver or my mom tonight or tomorrow, then report back to see what you think .

One thing I thought of is rather than having a door stop mounted as you suggested, would it be possible to hang the speaker on a thin piece of wood or metal that's hinged to the wall. That would allow for optimal toe-in adjustment, but then there's the weight of the speaker, and the chance of the door being opened before the speaker is put flush against the wall. Maybe Ian could comment on the hinged idea.

I'm not Ian, but I really like the hinge idea.

You could also hinge a larger panel with a cut-out for an in-wall speaker and have it recess into an opening in the wallboard, but I suspect you are going to get better LF response from the on-walls anyways due to the larger enclosure volume.

I just did some measuring, and the edge of the door is 3 1/2" from the wall, so on-walls would really interfere with the door. The other thing is that there's no way that each speaker can be placed at equal distance to left/right on my listening position. This is frustrating because I need something to work. If I could please get some other suggestions, I would greatly appreciate it.

can the doors open the opposite way. that is not a really good pic for me, it looks confusing are you using a special lens

There's a good chance that the equal distance left/right issue can be handled with balance control. I haven't played with that for a while but my recollection was that it worked OK - will do some testing. If it works I might shift my speaker placement slightly off-center as well because that would let the speakers go in much more convenient locations.

Will think about door interference some more. From looking at the picture my first impression was that the door would be able to open at least 60-70 degrees even with a toed-in on-wall but I don't know how well that would work for access.

Another option IF the balance control option works OK would be to move the right speaker to the left - wouldn't necessarily have to be enough to clear the door, just enough that it didn't have to be toed in. That way only the left speaker would need to be angled.

Ian, if you see this could you comment on LF response of in-wall vs on-wall and bookshelf ? Right now the frequency response numbers in the specs seem the same for all three, but they look a bit like initial copy/paste numbers rather than actuals (I'm assuming LF would be impacted at least a bit by the smaller enclosures).

I'm working with the assumption that without a sub Cam would be happier with the sound from on-walls than in-walls but I don't really know how big the difference would be.

Hey Cam you have a unique install situation. I would recommend not installing in walls in your room. Since you spend a lot of time in bed, you could in theory build a system around a nearfield multichannel bedpost setup. This would require smaller speakers mounted around your frame integrated into the bed posts themselves. This way you are guaranteed the same result, wherever your bed is setup. Since your listening distance would be reduced, you can get away with much smaller and lower output enclosures. This would save money as well.

A 4 poster with taller posts at the top of the bed would be your path to modular atmos with a quality HTIB package. An inverted U shaped setup at the foot of the bed would allow an articulating TV mount and your speaker locations. If you were smart about it your costs would be similar to what you are thinking of doing with inwalls. Less hassle as well for tweaking later.

11/4" emt conduit bent at a local electrical company would be a cheap and sturdy post setup. We have the odd dad get us to bend up hockey posts.

Hi Bridgman,

The LF of the on-wall and in-wall benefits from the boundary effect but that is not enough to equal the LF output from the bookshelf model.

Fixed that for you.


Thanks Ian. I'm going to pretend I knew that at one point but just forgot

I did a bit of testing to simulate Cam's wall-mount layout with my M5's - right hand speaker in fairly close & pointing straight ahead, left hand speaker "way over there" and toed in significantly.

Worked better than I expected (eg better than my results with speakers closer together but not toed in at all) although only maybe 8/10 for imaging compared to current location. I ended up getting best results by only partially adjusting the balance control and letting the soundscape spread further to the left... thought that would be odd but the result seemed pretty natural.

All that said I think Serenity_Now's idea of smaller speakers mounted more closely could work even better than anything we have discussed so far, although you probably would end up wanting a subwoofer to cover the lower notes.

The sub will be a tough one. Smaller speakers will mean a higher crossover point. This means more modes are affected and Cam's head is near a wall in bed. Dual opposing sidewall subs at mid bed might be a good compromise. Little guys like ep125 would work well.
