      All works, sounds really good and there is something slightly erotic, even prnographic, about seeing Atmos on the avr!
      Is that wrong?

      Finally got my new rear speaker stands and set everything up.

      Was a bit fiddly and unintuitive with the Marantz SR 7011 receiver, but got there in the end.

      Have tried a few of the demos and one in particular was very good. I'm definitely getting extra height and width, sounds amazing actually, but not much overhead as such. I suppose I don't have the "ideal" arrangement as it's 43 inches from the top of the PSB's to the ceiling at the front, and 37 from the top at the back.

      Any suggestions anyone? Boost output levels on upfirers? Adjust speaker distances? Or just accept that I won't get that in-ceiling effect in my room and set up and leave as is?

      I'd accept the last option as the system already sounds 50% better, so I don't regret taking the risk

      Boost your output levels 3-4db

      Well, going by Scoobie's recommendation above I would say yes.

      My Marantz SR 7011 doesn't offer Direct or Non-Direct modes, but it set all 4 of my PSB XA's to 0 dB and the effect was barely there.

      I've boosted mine to +6 dB all round and may end up tweaking it again, try yours at 0 dB and see how you get on from there?

      Hi, i bought a set of these recently from a member here and was struggling where to put them as i had just finished my small cinema room and all wires had been plastered into the walls.

      My front surrounds were already sitting on top of my stereo floor standers so had to find a place for these so i could sit my atmos speakers on top instead.

      I came up with this solution to stick my surrounds on the side of my floor standing speakers using a dozen large command strips.

      I have run the mic calibration on my Denon receiver and the results from the atmos speakers were quite poor....hardly any volume coming from them, they were in the minus setting but i pushed it up to +3.5 and now i feel there is new sound in front of me but not sure i notice anything coming from above.

      Can anyone tell me if they think these atmos speakers are too high, they measure 3 Foot 9 to the ceiling and i have put this measurement into the Denon.

      Still think it sounds quite a good bit better than the 5.1 i had but would like to tweak it a bit more if i could get better results.

      Thanks for reading.

      Hi

      I'm a bit confused:

      1. You originally had Front Height speakers on top of your Front L&R.
      2. You then bought some upfiring speakers to go Atmos (5.1.2?).
      3. You've now moved your Front Height speakers to the sides of your Front L&R and put the upfirers in their place.

      And your query is related to sounds above your head?

      My upfirers are 4 feet from the ceiling at the Front and 3 feet 6 at the Rears and I have a stippled Artex ceiling. I get very distinct extra Height effect mostly, with the occasional sound from above experience, despite not fulfilling Dolby's distance guidelines exactly.

      But I wonder if your speaker arrangement is nullifying the effect you're looking for? I mean, you've got Front Height speakers at the same height as your Front L&R and slightly below your upfirers - how does your amp work out the sound is meant to be? What arrangement is it, 5.1. what?

      Maybe you need to lose the Front Heights and just stick with the upfirers? You've certainly done the right thing by boosting their volume.

      @skirpydoink That is the strangest speaker set up I have ever seen. Even in a conventional 7.1 involving front height they are mean't to be high, not firing at you. The upfiring modules are correctly placed but now you have another set of totally useless speakers stuck to the side of your floorstanders. I shudder to think as to what kind of resonance that is putting into the floorstanders.

      You've not mentioned what receiver and in what configuration you have it set, if indeed that configuration is even available. Put a screenshot up of your connected speaker output.

      Yes, I agree :laugh:

      Its the strangest setup I have seen, I should have thought about atmos before I got my room done, I would have put speakers in the ceiling.

      To be honest, it does sound better than it did before I moved the front surrounds.

      The floor standers are not part of my cinema setup, they are wireless speakers just used for Spotify and TuneIn radio.

      I am at work just now, I will post the details from my amp once I get home if I get a chance.

      Cheers for the info.

      That goes a long way to solving the mystery of your set up. However my remarks on sticking the two speakers together still stands. They would be far far better off on their own stand or even wall mount. The modules would still work on top of your 'audio' speakers.

      Trying to get the perfect setup in these old council houses with curves ceilings and angular corners has me beat, I am starting to hear my stihl saw revving up to get those speakers wall mounted and in ceiling speakers.

      I must resist to after Christmas, my family will kill me, i make big changes to this cinema room every year but only recently took an interest in Atmos.

      Thanks for the help.

      Totally agree and can't see the point of the so-called front ' height ' speakers.

      I've just picked up a pair - what are people using as their crossover frequency?

      T-Force's query got me thinking today and I looked up the stats on the XA's:

      http://www.psbspeakers.com/content/160315123801-PSB_ImagineXA_Data_Sheet.pdf

      As you can see, PSB list the frequency response as:

      100-23,000 Hz
      LF Cutoff @10dB - 60 Hz

      I know it's best to set the crossover frequency so that pretty much all Bass frequencies are being met by your Subwoofer, that it does all the heavy lifting so to speak. But just out of interest, what would happen if we set the XA's crossover at 60 Hz? If, for whatever reason, you didn't have a Subwoofer, for example?

      Would this end up muddying the sound by having Bass frequencies handled by the speakers? Or would it create a fuller sound?

      Just wondering because, at the moment, they just sound like they're all Treble based on the Dolby Atmos demo disc.

      Thanks!

      You'd not accurately portray the frequencies below the roll off of the speakers. In some instances, frequencies below the roll off may even be inaudible or not be portrayed via those speakers at all. 60Hz is 40Hz below the rated roll off of the speakers in question and there's no benefit associated with outputting the frequencies below its roll off.

      The roll off is determined by the point at which the speakers' responce is no longer flat or consistent.

      So have I set the crossover too high at 150 Hz or should I try lowering it to 100 and see how it sounds? I suspect it won't damage the XA's if they have to deal with a little extra Bass.

      I dunno. Some opinions about Atmos speakers in another Thread got me thinking about this:

      These are ideal Atmos speakers......Honestly!

      It is suggested that the crossover for heights, upfiring or ceiling speakers be set in the range 150 - 200Hz. No, I'd not set the crossover lower than you've got it set now.

      I've got these and set the crossover to 200, if memory serves. I had to increase the output to around +8db, regardless of crossover settings, and they seem to create a good effect. Neural X is more pronounced than the Dolby setting. I presume everyone's ears are different and probably receive the sound differently to the Audyssey microphone, so I've adjusted output to suit how I hear the sound.

      I'm quite happy with it, but no doubt I'll fiddle around a bit more.

      Are you thinking of buying the XB's because you have concerns about tonal matching? Or do you want your XA's (I presume these are also on your shopping list?) to sit flush with your Front L&R?

      I can tell you that I have a PMC speaker set up with a Monitor Audio Subwoofer, and the XA's sound really good. I don't have super duper hearing, but I think the XA's are voiced to pretty much match with any speaker and they have definitely enhanced the sound both vertically and laterally.

      The XA's don't sit flush with the PMC's (both Front and Rears), they're not even the same colour! But I got used to their physical appearance very quickly and hardly notice them now.

      Hope this helps.

      Set these up today and not having much success...
      2 xa's on top of my front bookshelf speakers on stands, about 1.1m from the floor and 1.3m from the roof.
      Set up with audyssey, crossover increased, been trying 150 and 200hz. I have also entered the speaker to roof value.
      I sit approx 2.5m away, ear height a little below the height of the xa's.
      Audyssey shows distance from front speakers as 2.6 and the xa's as 2.7, so looks like the amp is picking up the direct sound from the speaker rather than the reflection. That is also what I hear, nothing overhead.
      Ceiling should be reflective enough, it's flat and has a slight artexed stipple, nothing severe.
      If I stand about a foot from the speaker, the sound is definately from overhead.

      Any ideas?
