    Best iPad App for Measuring Speakers in Room

    AudioTools. I thought everyone uses AudioTools on iPhones or iPads. But I would say it’s more of a Real-Time Analyzer. And you’ll need a calibration file for the Lightning port microphone you’re using. So you need to know how to interpret what you’re measuring… My audio dealer actually paid for...

    Avantgarde Acoustics Duo XD - first go at measurements and EQ

    While this is definitely true, in general, I find it’s easier to move the microphone than to move the speakers. That’s why I usually recommend re-measuring using REW by placing the microphone at new potential listening positions first. If moving the microphone forward and backward doesn’t change...

    Avantgarde Acoustics Duo XD - first go at measurements and EQ

    I suspect for the 100-250Hz dip, you won‘t be able to make a huge difference by moving the speakers. If you can move your listening position forward or backward, you can try re-measuring at 0.5’, 1’, 1.5’ in front and behind the current listening position to see if it smooths out the 100-250Hz...

    Mola Mola Tambaqui question

    I have not heard the Mola Mola Tambaqui. But my gut feeling is that if you like R2R DACs over Chord TT2, you’re unlikely to prefer the Mola Mola Tambaqui over your current R2R DAC. I think in the high-end, DAC architecture plays a dominant role in overall sound characteristics. If you feel that...

    Server vs laptop

    Perfect. So here’s a way to see if you might get better sound. Try playing music by unplugging the charging brick/power supply from the MacBook. Because Qutest has very decent galvanic isolation, for most modern Mac, playing from the MacBook using battery via USB should sound identical to...

    Server vs laptop

    I’m trying to figure out what is the current setup for OP. Why would a new server need 4TB if you’re currently playing off a MacBook Pro? Is the MacBook Pro running off batteries when playing music to the Qutest? Is the MacBook Pro connected to an external HDD/SSD when playing music? What...

    Avantgarde Acoustics Duo XD - first go at measurements and EQ

    So for the longest time, I don't have a dip at 80Hz for my left and right speakers independently but when combined, I do. Now that I use Acourate to create my DSP filters, I have a better understanding of why that is happening. It is not possible to estimate the summation of the left & right...

    Avantgarde Acoustics Duo XD - first go at measurements and EQ

    Hmmm... I think we all have different takes on measurements. First, I presume we are dealing with an asymmetric setup of the speakers in a room? Because you can see that it's not consistent across all frequency ranges (which it would be if the problem is the preamp or speaker alignment). The...

    Top Gun Maverick

    Airbus IMAX with Laser theater instead? I think Gaithersberg also has an IMAX with Laser theatre but it might be a second gen theatre with only 1 laser projector, instead of 2. Either way, It's almost definitely worth the drive for this movie. Unfortunately, I live in the middle of nowhere in...

    Avantgarde Acoustics Duo XD - first go at measurements and EQ

    If the boominess is more distinct 1 foot in front of the seating position, you can try putting the microphone at that position and re-measure to see what frequency the boominess is coming from. Another way is to go to the waterfall plot or spectrogram plot of REW to see which frequency lingers...

    Magico A5?

    I'm still mystified by the lack of power coming out of the A5 from the MC611. Now, in theory, the impedance of the 801N and A5 are fairly similar. But that doesn't necessarily mean that they can go in the same spot of the 611? I'm wondering, was your 801N connected to the 8 ohm or 4ohm or 2ohm...

    Magico A5?

    One thing that might still keep your hopes up that all will work out is that my dealer got a new A5 about 1.5 weeks ago. I dropped by to listen a week ago and right now. He has been burning it in 24/7 and I definitely here more low and mid-bass with more dynamics compared to last week. Would be...

    Magico A5?

    To me, it's not a total surprise you were a little disappointed by the A5. I agree with your fundamental assessment that perhaps your dealer didn't listen or didn't understand needs/preference of more low bass which you'll get more from the ported 801N, compared to the sealed A5. Particularly if...

    Room measurements and what to make out of them

    So I have definitely found many local "professionals" to know very little about room acoustics and are just there to sell you acoustic treatment products and then maybe hang them up for you. That's why I recommended the Acoustic Frontiers link because they seem to know what they are talking...

    Room measurements and what to make out of them

    I'm unsure what issues are trying to be addressed. is it the frequency response? Is it the RT60 in the bass or the RT60 in the midrange and trebles? I'm guessing pretty much any brand of 4" absorber panels would address most of these issues? But having read the other related posts, I wonder if...
