Very cool seeing it all come together Matt! Nothing new to you I'm sure but I have had amazing results adding a second-hand Lumagen Radiance Pro to my JVC rs500. Way less cost than a new PJ or MadVR Envy and I'm convinced you can't beat it with anything short of an NZ8. Like your rs540, it has higher native dynamic range than even an NZ9. Keep up the great work!
Really looking forward to the completed tour of your room, love the modern look. For Kef in-walls I’m assuming the RL line is basically the equivalent to their R series in bookshelf and tower speakers. Is that correct?
Hi Matthew! Killer room! I was so happy to hear you say you like Kef speakers! I am retiring from the Navy and instead of the motorcycle or watch, I'm going with Kef Reference 5 Metas, Technics SU-R1000 amp, and yup, Eames chair! Cause, well... Why the heck not! Thoughts? (Love your videos! Keep em coming!)
9:15 tbh the madvrs versus the new JVC tone-mapping, not sure I saw much of an actual improvement. it can look different, but not for sure better. I noticed the MadVR was pumping some of the blacks too much and revealing stuff that was probably not intended to be visible (below black content). Like when comparing on my OLED I noticed that the madVR was pulling up too much shadow detail. It for sure does stuff, but, not sure I see the value in it when you can get a JVC NP5 that would do your screen just fine without external processing.
That is good to know. I've not had any time back to back like that. I only know what others tell me. I've seen the Sony dynamic tone mapping against MadVR and I thought that was night and day. I have seen the JVC dynamic tone mapping and a JVC on a MadVR, but nobody turned off the MadVR and on the JVC tone mapping back to back to compare. I had heard the MadVR was a lot better, but I happen to think the JVC is good on it's own. Sounds like you agree.
@@PoesAcoustics I do agree. I saw a difference between JVC and MadVR, but I couldn't say one was better.. if that makes sense. One concern I had with the MadVR is it manipulated things a bit more, almost like using Photoshop and creating layers to pull details out of a photo in just specific spots. The Sony absolutely does need help tone-mapping, and to me using the Sony's doesn't make sense now because in order to get the best results you need to use the Sony + a video processor. Versus the JVC you can just use the JVC. The new firmware for the JVCs was an even bigger improvement in the tonemapping. Without help, the Sony's aren't awful for a casual but if you're someone that really cares about picture quality you'll end up in the menus all the time adjusting per movie which is really annoying. The JVC is set it and forget it.
Would you recommend holding out for Perlisten Atmos speakers, use Perlisten S/R4i, or KEF in-ceiling speakers to match a Perlisten bed layer system? (For height/Atmos channels)
I’d do KEF in ceiling becuse they are in the ceiling, I don’t think you’ll notice any difference like you may when they are going directly to your ear. Also, my dad has the SVS ceiling speakers which are excellent
Perlisten is the best option for match and the S4i could work but really isn’t ideal in a ceiling. However I’ve been using a Kef for other peoples installs and I think are very good. I would do Kef or wait for Perlisten.
I’d hate to not go with all Perlisten. Do you believe the ceiling versions will be significantly different than the rest of the line - i.e. not have the DPC? Seems like that is a big part of the Perlisten secret sauce. As long as the MLP is in the 30 degree on axis window of the in-wall DPC I’d think they would function well. I guess I’m just not sure what the in-ceiling versions will offer that are different from the in wall versions without straying too far from the Perlisten DNA.
@@derrondoc I was asking the dealer I bought my Perlistens from about this the other week & he told me the new Atmos range will have the exact same DPC etc so if he is correct I'd assume they may look a lot like the in wall series?
What are some things that only concentric/coaxial speakers can do (kefs) that other designs can’t do? Like time alignment? To me the physics makes sense from a geometry perspective. But the question is: is that academic? Thanks!
their design has the potential for more symetric dispersion and yes coincident designs have potentially perfect time alignment. But it is academic because Kef speakers are not time coincident but phase accurate. The phase response is correct but the time response is not. It's basically next to impossible to make a time coincident linear phase speaker using passive crossovers. It's technically possible with a first order, but then you have first order crossover issues. So in practice you need DSP to get both time coincidence phase perfect speakers and enough roll-off to get a good response. Kef could do this with active models. It's very debatable if the linear phase approach is audibly superior. I take the view that if you can you should, all else being equal, but if its going to introduce problems, it's not the main goal. Even with FIR filters for the crossover and response shaping, you can introduce problems like pre-ringing. I think their dispersion is their main advantage. For the LCR's its actually not a huge advantage as similar speakers like Perlisten or Revel have equally good or better horizontal dispersion and the vertical dispersion will show the same lobing errors due to the woofers. However, for the in-ceiling, I do think there is a real advantage. A Kef Uniq in-ceiling has perfectly symetric dispersion, which is really helpful for ATMOS speakers.
They each have trade offs. The S4 will be a bit more resolving and lower in distortion. The R5 is more efficient and plays louder. It also has better vertical directivity control. I would probably choose the R5 myself.
Hi Matthew, I’m am curious about using 3 each Perlisten S4s (on wall) as LCRs combined with 2 each R210s placed in the front corners. I would place S4s just above my TV angled down towards my listening position (my TV is fairly low - mid screen at eye level). With this setup I would be about 5 degrees below the vertical on axis location. I would probably use a crossover somewhere between 90Hz - 130Hz, letting the subs handle the lower frequencies. Do you have knowledge or experience of using the S4s in this manner? Would the sound seem to come from the higher location, or my ear level location? Thanks in advance.
I haven’t used them in this manner but we use speakers with a downward lobe in our projects quite a bit. Grimani systems builds a less steep 5 degree downward tilt to the lobe. We place the speakers above ear height in order to help the dispersion be unhindered by people. So the ventriloquist effect helps a lot here. Your brain will tie the sound to the talking heads. However you also have the visual cue of the speakers. Plus the angle is more extreme. So I am inclined to say this will work but you may notice a high soundstage. All home theaters are a series of compromises. The differences between the best and worst are how well thought out those compromises are.
@@PoesAcoustics Thanks for the quick reply. Just to recap - you are saying that you would NOT have major reservations using 3 each Perlisten S4s in this manner, with a pair of R210s? Thanks again.
What external DSP are you using? I searched the market for a multichannel digital DSP with TOSLINK/SPDIF connection but I couldn’t find any with the number of channels I require.
i'm contemplating between the Kef -R11 META, and the Perlisten R5T, they are both the same price in my country where i'm based, which one do you think it's better for home theatre use? which one would u personally pick if it was you? Thanks.
There is no simple answer to that. I sell both. Meaning I like both a lot. The Perlisten is a great home theater speaker, they have THX Dominus ratings on every product, that alone should tell you how good for theater Perlisten is. They are excellent speakers. Kef R11 Meta is a really good sounding speaker. They are rated for very good output, similar but a little below that of the Perlisten. In my opinion, the Perlisten has some advantages in construction quality. The R11 actually measures really good and may be a little better than the Perlisten. I believe the R11 could not pass THX Ultra or Dominus as is because its sensitivity is too low. I suspect that its not going to play quite as loud. So I don't know that I can clearly tell you that one is way better than the other for movies. Perlisten are great dual purpose speakers, with no compromises in movie reproduction. But the Kef isn't a music only speaker, its a far better theater speaker than most realize.
@@PoesAcoustics Thanks for the input, i did purchased the perlisten but still havn't got them yet , they are out of stock til the mid/end of August. Can't wait to get them 🙂
They are supposed to be pretty good. I've only ever heard them once or twice and I thought they were too bright, but that was probably the setup. They are easily tuned via DSP. I know some designers swear by them. I happen to have other brands I like better.
Hi Matt do you rate the KEF on-wall/ceiling Atmos speakers? I'm currently trying to decide which Atmos speakers will compliment my Perlisten bed layer (3x R5i & 4x R4i), unfortunately I can't really cut holes into my ceiling so I was looking at Arendal's Atmos range but I'm still just researching at the moment. I know Perlisten's belated Atmos range are still due out at some point this year but I've been told they'll probably be an in-ceiling design, which won't be practical for my situation plus to be honest I've blown my very modest budget on the bed layer so expecting them to be beyond my means.
The Perlisten Atmos are in ceiling. If you can’t cut holes those won’t work. They already have a wedge option. That’s alway the best match. Kef is very good but not sure they have a on wall that works for this. The wedge shaped models I think are only Q series and lower, no?
@@PoesAcoustics I'm not very familiar with KEF's ranges but just from a quick Google I think they do Q series for on walls plus I've seen an R series, which I'm guessing is a higher series & comes in at around £1,400 per pair in the UK. I'm also looking at the Arendal 1723 S which I can get for £1,170 per pair. I may end up just splashing out on x4 Perlisten R4S, which would obviously be the best option if money wasn't an issue. The main problem being I'm in the middle of renovating my house as well as building my HT & the rising cost of everything has blown my budgets so I can't see my partner being particularly happy about me shelling out £6,400 for x4 Perlisten Atmos speakers at the moment😆
@@northeastcorals that’s pretty much everyone’s problem. We all go over on renovations and speakers get pushed. I’ve worked on million plus dollar builds with clients scrutinizing hundreds or a few thousand on speakers. I don’t want to ever push someone into debt. You need to do what is right for you. However I would say that speakers are something that I wouldn’t compromise on either. Wire the room for what you want now. Buy the speakers you want now. But if budget is an issue, buy less of them. Upgrade later. Buying a lower end speaker is a commitment you can’t easily fix.
@@PoesAcoustics Totally agree with that! I can only imagine the frustration of working on a million dollar+ build & the client penny pinching over hundreds/thousands on the speakers 😅
@@northeastcorals it can be. I take these projects very personally and I feel that if my name is associated that the end result needs to meet my expectations. I don’t want to compromise on performance because the client can’t use speakers I know will work best for them. At best the sound is simply not as good or not as consistent. At worst the compromises actually hurt sound quality by limiting the systems ability to meet or exceed reference levels (or even close).
I feel like I need to re-watch this video. Did I talk about it and say it wrong? Forget the name? In any case, my bass traps are similar to the Modex Plate but different engineer behind them with different ideas. He actually worked with Modex plates and decided that some of the design was a mistake and refined it (based on lab testing) until he had a more optimal design. I always liked the modex plate, so I am glad that these are available again and at a price that isn't astronomical.
can you make a video of a full walkthrough of the room.

Yes but their in walls have a sensitivity difference which gives them a little more output.
