Recovering space in flush mount to enlarge the sweet spot

Dears, I've tried to flip the post but no clear answer ont his simple question: - CAN I CHANGE THE SLAT RESONATOR POSITIONING on John's COMPONENTS.spk (rendering below with yellow highlighting to understand what i mean) in order to recover the space from the wall to the flush mounting? I've made two assumption on the below renderings: 1) Slat with large part on the cieling and the low on the floor 2) Reverted SLAT Can some one tell me if the two options I've done (or one) of the two is viable without compromising the acoustics? (i will gain monitor space from 1.35cm to 1.80!!!) Thanks ALe

Its all about geometry. With those backward slats waves are going to hit directly at your face. The purpose of them is to make waves go behind your listening position and hopefully get absorbed at the back wall if absorptive

And the vertical solution?

One thing I did notice is that your desk / console is way too big for that room: With something that big, you have no choice but to have your mix position (ears) at 50% of the room depth. Worst possible position. Solve that problem, and your side walls should work out when done normally. - Stuart -

Thanks for the head's up... infact you are right... By now the positioning is at 45% of the room This is to respect the monitor 1.80 M space (see below picture) If i want to move the listening positioning to 38% i've to put it at 1.54 CM (see below pic). QUESTION: can i move it to 1.54 (38%) still keeping the monitor at 1.80 without big issues? Iwould love to do this to keep a larger listening positioning (i'm always with someone else). If not, better to move monitors to 1.54 distance or keeping listning positioning to 45%? Thanks in advance Ale

This is to respect the monitor 1.80 M space (see below picture) If i want to move the listening positioning to 38% i've to put it at 1.54 CM (see below pic).

Why do you need them at 1.8m separation? You could bring them closer together without any harm. It would also allow you to build bigger soffits (wider front panels), which would be good. Or if you really have to keep them at 1.8m separation for some reason, then you could just angle them more. It looks like you have them at a 60 degree intersect angle (acoustic axes). You could increase that up to as much as 90 degrees if needed. And yeah, 45% of room depth is awfully close to 50%: you'd only have to move your head back a few inches, and you'd be right in the null. I reckon I'd try to get a bit closer to 38% by either reducing the space between the monitors, or angling them more, or a little bit of both. - Stuart -

I would love to keep them as far as possible to WIDE the sweetspot. Is this not right? i will be most of the times with 2 people listening... and if the sweetspot is to narrow we will be having problem listening right. Is this not right?

Apart from which angle i choose (i red by the way that 60 is better than 90..is this true?) is not the RULE to have the a perfect triangle with every side of the same lenght? I mean if the distance from the speaker is 1.54.... does not the distance AMONG the speaker need to be 1.54?

I cannot comment on whether 60 is better than 90, but by definition, if the three distances are the same, the angle MUST be 60 degrees. If you used a 90 degree angle, then the angle between the front wall and speaker face would be 45 degrees, and the distance from you to the speaker would be 0.707*{the distance between the speakers}. So if your speakers were 1.8m apart, the distance between you and each speaker would be 1.27m. If you wanted to get to a 1.54m distance to the speaker, your listening angle would need to be 71.5 degrees - in between the two. However, please understand that if you have two people side-by-side, one will have a listening distance of approximately 1.3m from one speaker, and 1.85m from the second. Even if you were at the 1.8m distance and 60 degrees listening angle, the two speaker distances would be 2.06m and 1.6m. (this is assuming approximately 900mm between the heads of the two people) In both cases, you are nearly half a meter closer to one speaker than the other. So, in reality, sitting side by side with someone else, your ears wouldn't be at the 60 degree listening angle anyway.

That's a perfect descpription!!!! THNAKS.. So you are suggesting to not bother to much of 1 degree more or less and put them somehwere in beteween the 60 and the 90 and achieve a listening around the 38%.... Right?
