Thanks for sharing. That's pretty much what I'd expect based on the majority of this thread and also my own experience. I recently went from a smallish room using dipoles to a somewhat large one (20' x 20') using bipoles. The surrounds are selectable between bipole/dipole so I tried both modes that's just what sounded best for each room. The trick seems to be trying to remove localization without allowing the sound to get too muddled and chaotic.

Did you have a chance to try bipoles in either room?

No, never tried bipole. I have heard them in multiple demos and to me, they wound very much like monopoles.

I have a question not about speakers but placement for the surrounds.

I'm going to take my side surround speakers down a bit to better match the ear level. Would I want them placed more to 90° in a 7.1-setup or a little more to the back when my sofa and rears are near the backwall, around 2.5 feet? Will it get better separation with those at around 90°? I'm also planing for Atmos in a while. Does that impact anything with the placement of the side surrounds?

Here are pics with my surrounds. Thanks!

Spoiler!


Spoiler!

In your situation, I would only do a 5.1.4 layout. You won't get any real benefit from rear surrounds as there isn't enough space (angle separation) between the sides and the rears. I would, however, have your sides at about 100 degrees, so closer to the wall corner.

I can't see the front of your room, but you could perhaps do 7.1.4 (only with upper end Denon and Marantz gear, mind you) with 5.1.4 plus Front Wides, which might be a better solution in your case. You would take the surrounds you're using behind you now and then placing them in Dolby's recommended FW positions towards the front of the room. They help fill in the sonic gap between the screen wall speakers and the side surrounds. Dolby Atmos uses them all the time as does Neural: X upmixing and native DTS: X.

Also, drop the side wall surrounds to just above head level while seated. They're high enough so somebody's head doesn't block the sound from any other viewer, but low enough to have separation between the lower and upper speaker layers.

Listen up, studios! Just say "NO" to DNR and EE!!

Ideally, one would tonally match speakers by sticking within a line and brand - or so my studies thus far indicate - though less critical than L/C/R matching.

Given my less-than-ideal arrangements, I'm probably not going to be able to do this - I need really low-profile side surrounds that force me into a different brand than mains.

I'm hoping to convince my local dealer to set up the surrounds I'm looking at in the same room as the mains I have, should be pretty easy - but I'm looking for recommendations on a soundtrack that could put this to the test - to see how badly mismatched (or not) the speakers might be. Any recommendations?

Hi guys,

This is a really interesting thread and probably the best place where ask my question.
I can't decide what will be the best solution between bi-pole & mono-pole speakers for my room. Reading around it seems the best solution for my small room is a bi-pole,1 pole toward the viewers and 1 pole toward the lateral walls; but I've doubts because I don't have a reflective surface on the left (I can close that opening with some cloth but I think it will remain not sound reflective ???). Also the two walls have different distances from the central view point, I'm attaching a schema of the room that explain it better, I simulated the Monitor Audio Bronze FX.

This is my original thread where you can find others pictures of the room.

Hello, what do you mean with Multipole ? Could you link a speaker model as example ?

It was over 10 years ago I was faced with the Dipole/Bipole/Monopole issue and went Dipole due to THX influence at that time (and a typically english smallish room)
So far seems better sound placement (without being too direct as from a monopole)
And the Yammi 3040 YPAO doesn't pick up the out of phase units.

Next am gonna try a 130mm full range KEF Uni-Q in place of the downward firing woofer - seperately wired to the amp for rear presence/atmos.
I am looking into rewiring my Q2DS (put some more info in the KEF thread):

Any thoughts?

I have this same setup but with dipoles. One side doesn't have a wall. Surround effects are excellent IMO and you get great spaciousness as well. It's like the advantages of monopole and dipole at the same time.
