little extra:
With the help of A4 paper sheets, which you roll up and put into the base tube to make it slightly smaller in diameter, you can lower the tuning frequency a number of Hz, for example from 39 to 35 Hz. A different tuning of the speaker. Then you can get noticeably deeper bass, if...
No, not really. The group delay will be lower with high Q shelving and give you better sound because the overshoot will be also ”the other way” , functioning as a sharp high pass crossover right below the bass ports tuning point - where its needed. This will give lower distortion also in the...
Sorry for late reply :
1. At soundstage https://www.soundstagenetwork.com/index.php?option=com_content&view=article&id=1804:nrc-measurements-bowers-wilkins-704-s2-loudspeakers&catid=77:loudspeaker-measurements&Itemid=153 , it looks like it is at 39 Hz .
2. No, at 20 Hz the difference are only...
Good question.
You have to find the right settings for the peq and you must know the real tuning frequency of the loudspeaker.
As with everything, it might result in worse results than without. The resulting frequency response for the meta is a simulation, but it comes from experience of real...
This is a trick thats often used in studios to make the soundmix more fuller and more impressive - the use of high Q shelving function to high pass the signal . This can also be implemented in a ported speaker . And as very few streamers on the market, the WiiM can do this.
This can be done...
As i wrote earlier - you cannot correct anything with accuracy measuring from listeningposition above 200-300 Hz . The microphone must be calibrated and put 1 meter near the single measured speaker 200-20000 Hz to have a measurement thats the same as the ear/brain hears at listening position 4...
Yes, but the measurements below 200 Hz can be done with both speakers active.
You also need gating when measuring speakers above 200 Hz and youre in a room, or you need to have them outside the house.
You can ofcourse use the PEQ as a tone control between 200-20000 Hz when doing measurements from listening position with two speakers, and do adjustment to taste .
But those corrections will however not give you the ultimate sound because of the precedence effect. The mic has to be placed near...
Measurements below 200 Hz from listening position dont need differentiating L and R . But you cant correct anything above 200 Hz then :)
The rooms fundamental room resonanses can only be found below 80 Hz .
( Wall-wall, floor-roof , wall-wall )
Those three resonanses can be corrected in a good...
For the WiiM technical engineers - you can start looking at the Linn space optimisation how they have done it . With that approach , theres not any microphone needed , just mathematical calculations of the room size and corrections below 100 Hz .
This is the correct way to do room correction...
Late to the party but …. Nice to see roomcorrection implemented and more than 4 PEQ in the WiiM .
As an amateur loudspeaker builder ( have done some dsp models before ) and being a person who has done measurements on loudspeaker for 6 years , there is some missunderstandings about measurements...
Dont pay attention to scientific audiophile in this case .
Amirms review of the WiiM amp shows multitone at 5 W and the distortion is very low ( 0,002 % ) even when playing many tones at the same time. Im sure the WiiM amp can give a lot more than 5 W with multitone If the distortion criteria...
A Question:
Are there any proof that the digital part of WiiM pro and WiiM pro + even has a regulator inside at the USB power input ? Or is the 5 V DC (coming from the stock power supply) powering the digital circuits directly , without any 3.3 V regulator inside the WiiMs ?
Im talking only...
Are high slew rate and fast settling time really needed in a streamer that have a rather constant current demand ?
That said, I have tried WiiM pro with power bank, different linear supplies and an IPad charger from 2012.
I also had a very good streamer to compare with, a Linn Klimax DS reneew...
So…. How does this amplifier compare soundvice with the Linn MDSM4 ? Its probably the same tpa3255 or tpa3251 chip inside both amplifiers, but the Linn amplifier might have PFFB and a better powersupply.
