Hey Matt, Awesome videos. Love this series! Would it be possible to do a video about the Harman curve and how to properly set a target curve with your system?
Tonality from one speaker to the other being the same really helps cohesiveness throughout the room. I found out the hard , but cheap way. Now I'm pretty happy with sound "moving, moving around your room". 😁
Thanks. So I'll basically stick with Dirac's curves except i'll be raising the bass, which will be handed off to subs anyway. If I do apply a Harman curve I'll do it equally for all the groups. I'll also go in and raise the Q-150 height's x-over to 110 Hz. I think that'll be fine as Erin's dynamic range tests show they are fairly linear to around 110 Hz @ 96 dB. Thanks much Mr. Poes!

Variable freq limiters does exist and it's readily available for calibraters. Minidsp compressor function will do it 😊 They even have an 8 channel pre amp in and out processor for it. The processor is easy to use/abuse and it measures fantasticly too.
Thanks again for the great content, Matthew. I had heard about Dirac pushing speakers too hard. Audio Advice gave a rule of thumb in one of their videos that users should adjust Dirac curves to never go past +6db of the speaker frequency response. Curious if you agree with that heuristic.
You're not saying to buy expensive heights, but I bought Ascendo 10s for them because of this issue. I wanted 12s to match my bed layer, but they didn't have a 12 wedge that wasn't a Pro model
Hello Mr. Poes, Thank you for your videos, your work is amazing! I have a quick question: Could you please explain the difference (or what makes the difference) between inexpensive computer microphones with mono jacks versus regular calibrated USB microphones versus expensive professional calibration XLR microphones? I have a friend who believes that a $5 microphone is as good as a $100 calibrated microphone, is there a catch? I would appreciate it if you could provide the audience with some information on this topic. Thank you for your time and consideration. $THANKS Regards, Victor
Hey Victor. Thanks for the compliments. This inexpensive mic you speak of is of unknown anything so I can’t comment on it. It could be similar in response to that of a usb mic. But if it’s in calibrated, then the response is unknown and probably not flat. Even those $100 mics are cheap measurement mics and do not have a flat response. The response needs to be corrected to be more accurate. The main difference between a cheap plastic prepolarized condenser mic and a more expensive metal prepolarized mic is noise, dynamic range, response smoothness, and stability. For mission critical work, having a mic that is more stable over a range of conditions becomes important. When measuring max SPL, having good margin it’s important. When measuring noise floor, same deal. So professionals use mics that cost $1000’s of dollars often. But you can match the core 20hz to 20khz response and cover most of the same dynamic range with a $100 mic as you can with a $5000 mic. It just may not keep that same response in humid, cold, warm conditions or over longer periods of time.
Hi Matt. I had a question, but after watching, I have two questions. I have a 5.1 system that I’m happy with, and it’s using Paradigm Reference standing R and L with the matching Center speaker, with similar Paradigm in-wall surrounds. I just upgraded to a Yamaha A4A and have the ability to do a 5.1.2 Atmos-ish setup but wonder if it is worth it. (The AVR does 7.1, but I’m not interested due to small room and seating) My room is 11x15x8 used as a living room, having a couch on each of the long walls and 3 retractable theatre chairs along the back wall that’s rarely used. Do you think adding two in-ceiling speakers would be an upgrade or just add noise? Second question. You mentioned certain Paradigm speakers not be up to the task. I had planned, if I decided to add ceiling speakers, to install Paradigm’s ci home angled tweeter in-ceiling speakers, or perhaps the ci pro step up version. Do you think those are a good choice to match my LCR, or is there another speaker/brand/model that you think might better serve me? Also, you mentioned an enclosure for in ceilings? How’s that work for that type of install, where you cut the hole and the speaker clamps into the drywall? Do they make a product that can be positioned in the hole to provide an enclosure? I saw some foam type product years ago, but I’m not sure if that would work.
Good video! You recommended the same curve for all speakers. Storm uses different target curves for LCR and Surrounds. In what situations would this be advisable?
I don’t know why you would do that. Matthew is a good friend so I can ask their rationale. But the goal is to timbre match all speakers. So why a different curve.
@@PoesAcoustics The LCR curve is more flat than the surround curves. The sureounds get a steeper curve. I assume they do this as the surrounds are usually closer than the fronts. Please ask him what is their rational. I think it sounds very good.
HI Matt. If the +- 3db point on the low end of the frequency range for a speaker were 80hz (in this case a small KEF UNIQ) would you still always set its crossover higher?
I thought you shouldn't go over 120hz for crossovers due to localization. But you're saying 150hz is okay? I have some sattelites which could benefit from this.. I just always thought it was a no-go. These sattelites rolls off at around 120hz. Should you set the crossovers for them at 120 or 150? Would 150 make them be able to play louder without distortion? I watch at reference levels. Can you elaborate on this Matt? Thanks for your content.. much appreciated!
There is no single hard and fast rule here. As you increase the crossover point the bass becomes increasingly localizable. There is no doubt they 120-150hz is in the area where it could be localizable. But you are balancing it against other problems like distortion.
I set mine to 120hz, all around including atmos but I have 4 subs, one in each corner. After calibration, they are not localized at all. I did this after watching one of audioholics videos with Matt discussing if 80hz was the right xover. In the end, it depends but with multisub, it's alot easier to get away with it.
@@MrDante10no Two biggest excuses for NOT having the same speakers everywhere, 1st and most common is " I can't put towers everywhere" answer, you shouldn't have tower speakers in a home cinema system anyways. 2nd excuse is " I haven't the room on the ceiling" 🤔 despite having the entire ceiling unused 😒
Mine are the same brand - same line. All of the tweeters all the exact same tweeter model. Helped greatly. However, I need more lots more speakers. (Evil Laugh - - - - - - - - ) 😁

I was doing 70Hz specified by Dirac for my Polk heights. After extensive testing, they made a popping noise until 120Hz which is where I kept them 😊.

Speaking of target curves, will you be trying or reviewing Joentells Magic Beans? Or if you have already tried it, thoughts?
Would love to see his thoughts on this
A1 Evo from OCA is way better than magic beans, and its free! try it! you wont be dissapointed
Also want an answer to this

Another fine reason to have every speaker the same...
Not possible, especially with Atmos/DTSX/Auro 3D and height speakers.

You should upload a video to your channel showing that you used one model for all speaker positions

Lol google what POES in South Africa means
anyway great video
